UPnP+ links non-IP devices to wide-area networks

UPnP+ links non-IP devices to wide-area networks | EETasia

My Comments

The recent extension of the UPnP Device Architecture specifications, known as UPnP+ is being worked on at the moment by the UPnP Forum. This is to extend the reach of the UPnP Device Architecture specification sets to satisfy certain new realities.

One key reality is to make UPnP work properly with the “Internet Of Everything” concept. This is where devices are able to interlink with each other and share their information in a manner not dissimilar to the concept associated with the Internet.

It will be achieved with native support for IPv6 across IP networks. This takes advantage of the huge number of addresses this standard offers compared to the legacy IPv4 which most of the Internet works on at the moment.

As well, a SensorBridge Device Class will be defined. This caters for the “bridge” device that links sensors and similar devices that work on non-IP networks with IP-based networks. The article talked of the non-IP wireless-sensor networks as being Zigbee, Z-Wave and ANT which take advantage of low-power low-overhead operation suited for those fields. These devices could be represented by “black-box” devices that stand between an Ethernet or Wi-Fi-based home network and the sensors or controllers such as the Honeywell Evohome Mobile Access Kit, but could also be represented as software integrated in either a router that also has a Zigbee or Z-Wave interface or a smartphone, tablet or laptop with Bluetooth 4.0 Smart interface.

There will also be inherent support for cloud-based “hosted” services to be part of the UPnP ecosystem. Of course, I find that the term “cloud” alludes a lot to services hosted by other parties away from the main home network, typically to provide remote access from smartphones, tablets and other computers connected via the Internet. In the context of “Internet Of Everything”, it could extend to service providers like utilities or monitored-alarm companies using this data to participate in the “Smart home” concept.

I would see this come in to its own with home and other networks that are operating along the line of “Internet Of Everything” and this could be supported with newer devices that have newer UPnP+ firmware in place.

Desktop security moves from virus-hunting to more tasks according to Symantec

Antivirus Is Dead — Long Live Antivirus | Krebs On Security

What did anti-virus software do?

McAfee LiveSafe desktop security program

A typical desktop-security program in action

Previously, an anti-virus program was regularly vetting software against a known signature-based list of virus software or, in some cases, Trojan-Horse software. Better programs of this class also implemented “heuristics-based” detection that observed software behaviour for known virus-like characteristics.

The software authors beihind the anti-virus programs were playing cat-and-mouse with the malware authors who are trying to get their rotten software on to our computers. For example, malware authors use “crypting” services to hide their software from the gateway software, typically through the use of obfuscation.

What have the anti-virus software programs evolved to?

These have evolved to robust “desktop security” software suites that perform many different security functions for the computers they are protecting.

Firstly they work with your email client software to vet your incoming email for spam and phishing emails. This will typically work with client-based email setups like Outlook, Apple Mail, Windows Live Mail and others rather than Webmail setups like GMail or Hotmail.

As well, they implement a desktop firewall that  verifies traffic coming to and from the Internet and home network so that malware can’t easily “report to sender” to fulfill its task.

They also implement a wider malware-checking mandate such as catching out rootkits, adware and spyware. Sometimes this is done on a “software reputation” mechanism or observing for particular behaviour traits.

Another function is to implement a “reputation check” for the websites that you visit. This checks whether a Website is a host for questionable software or implementing other questionable practices. This may also be included with a desktop content-filtering function which filters against pornography, hatred and other undesireable content.

They also work as a privacy watchdog by monitoring Websites or social-media services for improper activity that threatens your privacy or that of your child or other vulnerable person.

But, wait, there’s more!

Some of these programs offer extra functionality in the form of a password vault which looks after the passwords for the Websites and other resources you visit.

They may offer a client-server VPN so you can use the Web from other networks like your friends’ and relatives homes or public networks in a secure manner. Similarly, they offer a secure file-storage option, whether on the cloud or on your local machine.

Different levels of functionality available

Most desktop security suites pitched at the home or small-business user tend to be sold with client-focused manageability where you set their parameters to manage that particular client computer. If you have multiple computers, you have to manually replicate that same setup across those computers. As well, they are priced either “per machine” or in a licence-pack that covers up to five or, in some cases, ten machines. You may be lucky to have the software provided as a site-licence that covers equipment owned by a particular household.

Conversely, desktop-security software that is targeted at the big business or at some small businesses is set up for management of multiple machines from one logical point. This includes the ability to deploy the same software across multiple machines yet have the same standards preserved across the multiple machines. They are typically priced in licence-packs that encompass many machines or may also offer a site-licence deal which covers all equipment kept at a particular location or by a particular organisation.

Prototyping electronics the inkjet way–to come soon

Home inkjet printer fabricates circuit boards on photo paper | ComputerWorld

Video

My Comments

There have been a few methods for building electronic-circuit prototypes which involved a “breadboard” of some form and having the components anchored down with either mere friction, with wires inserted in a spring or screwed down with a screw and washer. This was either used to teach electrical and electronics concepts or to “rough out” an electronic-circuit idea and having it work properly before spending time on building a printed circuit board for permanent deployment.

Now Microsoft have come about with a method of making printed-circuit boards using the common inkjet printing method that most printers (including a lot of the ones reviewed here) implement. Here, users could design a circuit using a regular computer and print this out on the photo paper. But the inkjet printer would have to be equipped with a cartridge that holds a special conductive ink and think it is printing something in black and white.

You could then think that you have to solder down the various regular components like diodes, resistors, capacitors and transistors, punching their wires through the paper. But this could prove to be difficult with heat-based soldering and wires attached to the components. Instead, Microsoft and 3M are implementing “stick-on” components that are conductive through the tape as a way to build the circuit that work in a similar way to a SIM card where there is conductive areas on that card.

There would be the requirement to use card-grade paper for improved mechanical reliability as well as the ability to connect regular wire to these circuits whether to connect regular batteries, switches and the like or connect between two circuits. Another issue would be to provide the conductive-ink cartridges for most of the currently-issued inkjet printers so that one can get going with using these printers for turning out the printed circuit boards.

But what I see of this is that equipment used by most computer users could come in to its own with learning electronics or building electronics circuits, especially “short-order” circuits. At the moment, the idea hasn’t been commercialised but the kind of people who could make it sell would include the educational sector or electronics shops of the Maplin, Jaycar or Radio Shack kind.

CableLabs have given their blessing for DLNA CVP-2 standards for premium-content delivery in the home

DLNA CVP-2: Premium Content to Any Device in Any Room

My Comments

Consoles like these could be able to pick up pay TV from a DLNA CVP-2 gateway device

CableLabs have cemented their approval for the current iteration for DLNA Commercial Video Profile 2 to provide for improved in-home pay-TV setups using the home network. This leads effectively to an FCC goal that requires device-independence for cable-TV setups in the home rather than users being required to lease a set-top box for each TV in the home or install a “TV Everywhere” app provided by the cable company on each mobile device if they want cable TV on the extra screens.

What is DLNA CVP-2?

This is a super-standard defined by DLNA which uses a group of standards to assure pay-TV networks that their content is being delivered securely and surely to the display device via the home network. Here, the display device can be a Smart TV or video peripheral with “Connected TV” capabilities or software in a regular desktop / laptop computer or mobile device (tablet / smartphone) to show the TV content on the screen.

Sony BDP-S390 Blu-Ray Disc Player

.. as could these Blu-Ray players

It will typically require a so-called “gateway device” connected to the cable system, satellite dish and/or Internet service, such as a broadcast-LAN tuner, router with broadcast-LAN capabilities or a PVR in the customer’s home while display devices and software would have to authenticate over the home network with the standards that are part of the package. The PVR solution may typically be connected to the main TV set in the lounge or family room where most TV viewing is done while TVs installed in other rooms like the bedroom can use the home network to “pull down” live or recorded TV content using “smart-TV” abilities integrated in the set or a games console / Blu-ray player.

DLNA media directory provided by server PC

.. as could these Smart TVs

There is the use of DTCP-IP secure-content-delivery specifications for IP-based home networks to authenticate the access of content to cable-TV / content-studio / sports-league requirements. As well setups that implement DLNA CVP-2 implement RVU which provides the same kind of user interface expected when you use pay-TV services, which could facilitate things like access to video-on-demand and pay-per-view content, access to the service provider’s TV-hosted storefront and magazine, or ability to schedule PVR recordings.

Another benefit provided by DLNA CVP-2 is to support endpoints that implement a very-low-power standby mode and allow them to use wakeup and network-reservation mechanisms to allow the efficient-power modes to operate but provide for proper useability and serviceablility. This avoids service issues that are likely to happen if a device goes to an ultra-low-power quiescent mode when not needed and finds that it has to create a brand new connection to the network and its peers when it is needed.

Do I see this as a change for delivery of the multichannel pay-TV service?

One reality is that DLNA CVP-2, like other technologies affecting TV, won’t change the calibre of the content offered on pay-TV services. You will still end up with the same standard of content i.e. a lot of channels with nothing worth viewing.

But it will affect how a pay-TV company delivers services pitched towards a multiple-TV household. They could offer, either as part of the standard service, as part of an upsaleable premium service or as an optional item, a “multiple-TV” service. This would allow a person to have the pay-TV service appear on all suitably-equipped screens instead of paying for each TV to be equipped with a set-top box.

Similarly, the main device could change from an ordinary set-top box with PVR abilities to either one with the “gateway” abilities integrated in to it or a “headless” gateway device with broadcast-LAN and PVR abilities. In this case, the main TV would either be a suitably-equipped Smart TV or be connected to a video peripheral that has this kind of “connected TV” functionality built in. It could also change the focus of the value of the customer’s bill towards the content services rather than the customer-premises equipment.

For consumers, it could be a path for those of us who move between pay-TV or triple-play services whether due to moving location or moving to a better offer. This is because there isn’t the need to mess around with set-top boxes or create infrastructure for a pay-TV service that implements different methodologies.

Pioneer to bring Apple CarPlay to some newer aftermarket car stereos

Apple CarPlay Coming To Pioneer’s In-Dash Systems This Summer | Engadget

From the horse’s mouth

Pioneer

European Press Release

Product Page

My Comments

The talk about Apple’s CarPlay in-dash infotainment operating system has been focused on vehicle builders providing this as standard with particular car models. But Pioneer, who is well-known for a long run of high-quality car-infotainment technology for the vehicle aftermarket, has become the first company to launch an Apple CarPlay setup for this application class.

This will be available as an up-and-coming firmware update for a few of Pioneer’s premium “double-DIN” multimedia head-units that are being launched this year. The units, some with and without optical disc will have the large LCD touch screen as the operating system but will require the use of a iPhone 5 or newer device running iOS 7.1 or later to run with the new operating environment. They will also be connected to that iPhone via a USB-Lightning “charge and sync” cable. Key advantages will come in the form of access to Apple’s assets like iTunes, especially iTunes Radio, the reformed Apple Maps along with the Siri voice-driven “personal assistant”. There will be some driving-appropriate third-party apps like Spotify or TuneIn Radio that will be made “CarPlay-ready” as they are developed or revised for the iOS platform.

What I see of this is that the aftermarket scene, which will cater to the younger drivers who primarily start out with older vehicles, will need to embrace Apple’s CarPlay and other similar connected-infotainment platforms offered by Google and Microsoft. As well, it is showing that the vehicle is becoming part of the home network and the Internet and heading towards a platform-driven connected environment rather than one directed solely by the vehicle builder.

Dolby to provide a personal soundtrack for sporting and cultural events

Article

Dolby’s vision for the living room includes abundant audio options | Engadget

My Comments

Most of us who watch sports have a preference for a personalised audio experience during these events. For example, a common method of enjoying cricket in Australia is to have the TV’s volume turned down and the ABC radio commentary playing on the radio or hi-fi. This is due to “cutting out” the TV advertising as well as listening to cricket commentators who know what they are talking about.

Similarly, I have watched the Tour De France on SBS and do enjoy the English-language commentary that is provided but have had a taste of the French commentary when there was a technical mishap and would appreciate that, due to my knowledge of the language. Sometimes, a simple “music-and-effects” soundtrack for a royal wedding or similar public ceremony may suffice as the audio experience rather than what some might see as a “slanted” commentary.

Dolby is putting forward the idea of a highly-personalised soundtrack for sporting, cultural and other live events that can include one or more different commentary streams along with, for example, effects or other “event-driven” sounds that follow something like a social-media stream. This can be derived from “existing infrastructure” like broadcast commentary, or IP (the Internet) which could be something like an alternative radio or TV commentary or a “text-to-speech” of Twitter comments from your friends.

Of course, they say that it could require additional hardware at the broadcaster’s and consumer’s side for this to work but a lot of smart-TV and set-top-box platforms that have an Internet connection of some sort could adapt to this easily through a firmware update or the delivery of an app.

This application for interactive TV could be a godsend to those of us who love our sporting and cultural events our way.

The 3Play Bluetooth audio adaptor answers the multi-device problem

Article

3play is a Bluetooth audio dongle that begs to be misused | Engadget

My Comments

A common problem that affects any Bluetooth audio and mobile-phone setup is the way that most Bluetooth devices handle multiple source devices. I have covered this issue in a previous article concerning managing multiple Bluetooth source devices with one Bluetooth destination device (headset, speaker, etc). Here, I even highlighted how desktop and mobile operating systems don’t even handle connecting and disconnecting of these devices very well save for Android and Windows 8 and it requires you to pair up your wireless speakers with your iPhone every time you want to use them again.

3Play have come up with a Bluetooth audio adaptor that allows 3 source devices (smartphones, tablets, MP3 players) to this adaptor at the one time. In this implementation, if a device is paused, another device could be playing out the music, thus being based on a “priority” method.

What I would like to see of this is that 3Play could license the software out to other manufacturers who sell wireless speakers, Bluetooth audio adaptors and the like to allow for priority-driven multiple-device handling. Another way to solve the problem could be to enumerate each connected device as a logical source or sub-source which would work properly for home and car stereo systems. Here, a user operates a control on the system like a “Source” or “Band” button to select the Bluetooth device to listen to.

At least 3Play are answering the common problem associated with people showing up with Bluetooth-capable smartphones and tablets full of music and pairing them up to the same wireless speaker or music system.

Why do I give space on this site to the network-capable CD receiver?

Regular readers may have noticed me giving some space to the network-capable CD receiver of the same ilk as the Rotel RCX-1500, Naim Uniti series, the Cyrus Lyric series and Sony’s newest offering in the form of the MAP-S1. I am writing about why I give coverage to these systems as a network-capable music-system option.

The rise, fall and renaissance of the high-quality integrated system.

Cyrus Lyric network-enabled CD receiver

These followed on from the “music centres” or “compact stereos” of the 1970s and 1980s which housed a turntable, receiver, cassette and / or 8-track cartridge deck in one box connected to a pair of separate speakers. Systems of that class that were worth buying approached a functionality and sound-quality standard that was equivalent to a baseline component-style hi-fi system.

Some users preferred to buy this class of integrated music system because of the fact that it was simpler to use or understand and there was less to worry about compared to a component-based hi-fi system. In some cases, it meant that the system ended up being used by more members of the household for more music-enjoyment tasks rather than one or two highly-knowledgeable people.

This kind of standard for integrated home audio had died out through the late 1980s with Bang & Olufsen, Bose, Proton, Onkyo and a few others carrying the flag through the 1990s and beyond. This was while integrated systems that most people could afford at that time didn’t hit the mark for sound quality or, in a lot of cases, functionality or build quality.

The category resurfaced in the late 1990s with NAD, Denon, Onkyo and a few others offered CD receivers and DVD receivers that didn’t come with a set of matching speakers. One UK hi-fi magazine even described it as the return of the 1970s-era music centre. Onkyo even fielded a system that could be considered today’s equivalent of the music centre by offering the FR-435 which had a CD player, FM receiver and MiniDisc deck in one box.

The network-capable CD receivers mentioned here take on the CD-receiver concept and become part of the home network to provide access to Internet radio, online music services and music stored on that network.

The typical network-capable CD receiver

Amplifier design

Rotel RCX-1500 CD receiver

Rotel RCX-1500 CD receiver

These CD receivers are typically built with amplification sections that could approach that or, in some cases, be equivalent to. a competently-designed baseline integrated hi-fi amplifier. This means that they can be used with any pair of competent speakers that the customer chooses to use it with.

There are a few examples of this concerning music systems of this class that come to my mind. One was a demo setup for the Onkyo FR-435 CD/MiniDisc receiver which involved it being connected to a pair of floor-standing hi-fi speakers made by a hi-fi “name of respect” and I had played a personal-compilation MiniDisc through this setup with it performing very competently..

Another was the review setup that International Dynamics provided me with when I reviewed the Rotel RCX-1500 network-capable CD receiver. This setup consisted of the CD receiver and a pair of Cabasse Antigua bookshelf hi-fi speakers connected with a pair of very-low-resistance hi-fi-grade speaker cables.

Marantz CR603 CD receiver

Similarly, when I was at the Australian Audio & AV Show 2013, I had seen and heard a preview sample of the Cyrus Lyric network-capable CD receiver in full flight with a pair of Quadral Montan floor-standing speakers. This was, at one time, streaming music from a Bluetooth-connected phone or, earlier on, playing music off a CD.

These systems can easily serve certain realities concerning the availability of speakers.

One could be that you already ended up with a pair of good speakers. For example, you have ended up with Dad’s old Klipsch hi-fi speakers when your family were clearing out your parents’ house after he passed away and Mum had to move to supported accommodation. Or you went to an estate sale or auction and ended up with a pair of hi-fi speakers of a respected audio name that were in good condition for pennies’ worth.

On the other hand, you could be able to buy the CD receiver with a pair of speakers that suit your needs and budget at the hi-fi store you were buying it from. This may also include being able to look at what the hi-fi store offers when it comes to second-hand speakers in very good operating condition which could be trade-ins or a pair or two that they are tasked with selling on consignment.

Functionality

Naim Uniti network CD receiver

These systems offer a CD player, FM/DAB+ radio, USB file-based audio playback along with network-based AV sources like Internet radio or DLNA audio playback in that one box. Newer generations even come with Bluetooth A2DP audio play from mobile devices along with access to various online audio sources other than an Internet-radio directory, like Spotify, Deezer or Pandora.

The limitations that may be exposed by these systems may include fewer connections for other audio devices. This may manifest in the absence of a phono stage where you can connect most turntables equipped with a magnetic cartridge or the absence of a “tape-loop” where you can connect a recording device like a cassette or MiniDisc deck and be able to record from or play to the CD receiver. As well, you may only find up to two line-level inputs on these systems. The reasoning behind this is that the network-capable CD receiver offers most functions in that one box.

Build quality and longevity

Sony’s new entry to the CD-receiver scene

I draw attention to these systems due to them being built to last which is important if you do either expect to use it frequently or see it staying around for a long time. It also underscores amongst users that they want to frequently play a well-built system that is less likely to break down with the regular use.

Newer systems will even implement user-updatable firmware to allow the system to support new online music services or newer networking standards and audio file types.

In some ways, the longevity that these CD receivers offer would justify the price tag especially in this economic climate where the idea is to look for value and durability so you don’t end up spending too much over the long term.

Relevance

Smaller residence

Arcam Solo Neo CD receiver

Arcam Solo Neo CD receiver

The network-capable CD receiver is intended to satisfy a trend for smaller living spaces which is likely to become the norm for two main user classes. One user class would be a tertiary student who is living in student accommodation i.e. a student hostel, college dorm or residence hall. This would also extend to people living in accommodation associated with their job where the accommodation space is a small apartment or a room of a similar size to a hotel room. This also includes people who share a house and find that their private space is simply a bedroom.

Another user class would be a retired person or couple, or a couple whose children have flown the “family nest”. Here, these people would opt for smaller premises such as a decent-standard inner-urban apartment located close to city activities like the good theatres, or they could be living in retirement or assisted-living accommodation which would typically yield a small bedroom or a small apartment.

Both situations may not easily accommodate a stack of regular-width hi-fi components due to the small size of the living quarters or having such equipment may overwhelm these spaces.

Secondary music system

Even a larger house where you can have a “stack” of hi-fi components as your main A/V or audio system may yield a space where a secondary audio system may be desired. Examples of this may be a secondary lounge area like a large landing or foyer; a dining room or simply a master bedroom. To the same extent, these systems would earn their keep in a small office or shop, providing high-quality music for the patrons.

All these situations could easily be passed off as being suitable for a cheaper music system which is something you would do on a budget. But for those of us who want high-quality sound without an underpowered amplifier straining because too much is asked of it or are used to a good hi-fi system serving your music needs, these network-capable CD receivers could simply answer these needs.

This can also extend to a high-quality three-piece music system that you may want to set up in your shop or office to reflect the tone of your business. The network ability could then allow you to benefit from music held on a small NAS or online-hosted music services like the “new shortwave” that is Internet radio.

Changing needs

It is more so if you have changing needs and can easily purpose these systems either as a primary music system or a secondary music system as required. An example of this could be to purchase one of these units as a secondary system for the “den” in the large house, then take it with you to the small apartment as the hub of a decent music system.

Conclusion

I do give space on this Website to the premium network-capable CD receivers due to them being able to be the heart of a well-built good-quality music system that caters to the downsizing trend that is affecting how we live nowadays without losing on the good-quality sound that a lot of us are used to.

Google to use the Chrome platform to build a TV-hosted photowall

Turn Your TV Into An Interactive Scrapbook With Chrome Photowall | Fast Company

My Comments

Media contents in Dropbox folder available on DLNA-capable Samsung smart TV

With Google Chromecast, a smart TV could become a photowall

A friend of mine who likes “scrapbook walls” as part of parties or as a way to represent their children growing up. She typically used A0 or A1 sheets of card to either glue cutouts of photos or even pinned one of these sheets up on a wall during her 21st so people can leave messages wishing her happy 21st birthday.

Google has taken this further by making the TV screen become a photowall using a Chromecast “server” app alongside client apps for iOS and Android mobile platforms and a Web page that is part of the server platform.

Here, guests can upload messages and photos on to this photowall from their mobile devices or the Web page and they appear on the TV screen associated with the Chromecast device.. There is the ability to have “tiling up” occur for the photowall with pictures come in at different sizes.

According to the article, this software is not a polished product. But I see it appeal to other software platforms such as the “smart-TV” / connected-video-peripheral app platforms or just simply the “regular-computer” platforms (Windows and MacOS X) for display functionality. It could also work well with support for user-nominated “image pools” like NAS directories, DLNA content pools, Social-Web albums or “cloud-storage” folders.

Similarly, it could support the concept of a single “content-and-control” server which could control how pictures appear on multiple screens. This could appeal to setups where you could run multiple photowalls such as during a large party.

The Google Photowall concept could be all about realising the fact that multiple pictures can be displayed at the same time in a manner that appeals to most consumers.

Sony enters the network CD receiver market as part of their new home AV lineup

Sony’s expanded High-Resolution Audio line-up brings you musical clarity you’ve always dreamed of (Press Release)

My Comments

Sony MAP-S1 CD receiver courtesy of Sony

Sony’s new entry to the CD-receiver scene

Sony had launched some newer hi-fi components in to the European market including the STR-DN1050 and STR-DN850 surround-sound receivers and the BDP-S7200 optical disc player which can play SACDs or Blu-Ray Discs. All of these can be part of the home network by implementing at least DLNA functionality and access to varying online-content services with the receivers even supporting Bluetooth and AirPlay functionality.

But what drew my attention to this playlist was Sony climbing on to the high-quality network-enabled CD-receiver bandwagon by offering the MAP-S1 CD receiver. These are systems that have a CD player, broadcast-radio reception, amplifier functionality and, now. access to network-hosted and online content like Internet radio but are optimised for high-quality sound. They take on the spirit of the late-1970s music centre or cassette receiver (casseiver) where a very good unit of this class could offer what a baseline component-based hi-fi system of the time offered in both sound quality and functionality.

Previously, I had given a fair bit of space to the network-enabled CD receiver, including my review of the Rotel RCX-1500 as well as a fair bit of commentary about this product type in my coverage of the Australian Audio And AV Show 2013. This is due to the “lifestyle audio” product class becoming more relevant as the small elegantly-furnished apartment becomes more relevant especially for those of us whose children have flown the family nest.

This product is different from their CMT-series micros systems due to the idea of users being optimised for high sound quality. One of the factures was that a user could supply their own speakers for this system or they could purchase a pair of Sony high-grade bookshelf speakers and use them, very much like Onkyo’s FR-435 CD/MiniDisc “music-centre” system.

The Sony MAP-S1 offers the network connectivity for DLNA, AirPlay and access to online music services like Spotify and Internet radio, and also offers the ability to work with Bluetooth smartphones using the NFC pair / connect functionality and the aptX codec. As well you can have it become a USB DAC/amplifier for a computer thus exploiting the high-resolution audio content available for download if you host that on a Windows or Mac regular computer.

One question that can be raised with this class of network-capable AV equipment is whether the equipment will support dual-band wireless networks whether using 802.11n or 802.11ac technology. Similarly, there will also be the issue of network and online functions not being available with developments that offer “headline” Wi-Fi Internet that implements Web-based login. In these situations, the Sony MAP-S1’s Bluetooth and USB Audio functions would come in to their own when it is used with a regular computer or mobile device to “pull in” online music services including Internet radio.

As more of these network-capable CD receivers come on the market and yield the high-quality sound, especially from mainstream as well as boutique AV-equipment manufacturers, a compact hi-fi system for that apartment or house could be about buying one of the CD receivers and buying or resurrecting from the garage a pair of good hi-fi speakers.
