Sat-IP: Sat-TV im ganzen Haus – AUDIO VIDEO FOTO BILD (Germany – German language)
From the horse’s mouth

Just lately, I had published an article on this site about the concept of broadcast-LAN devices like the Devolo dLAN SAT and the HDHomeRun devices. These use at least one integrated broadcast tuner to stream broadcast signals received via a regular antenna (aerial), cable-TV setup or satellite dish around a small network using the protocols associated with these networks. The content is picked up from the network using software installed on regular or mobile computers to be displayed using their screens and speakers.
Now, SES, BSkyB and Craftwork who are heavyweights in Europe’s satellite-TV industry have set up a branded standards group called SAT-IP. This group determines standards for setting up satellite-based broadcast-LAN devices and promotes the concept of satellite-based broadcast-LAN systems. This is very relevant with the European market where satellite TV is considered a preferred medium for delivering supplementary TV content such as free-to-air from other European countries or pay-TV content from one’s own country or one of many neighbouring countries.
Here, they had worked out a data standard which is effectively based on the UPnP AV standards and is to co-operate with that standard but allow for satellite-TV tuning. They even wrote in support for DVB-T/T2 terrestrial-TV setups primarily to cater for the MATV systems implemented in multiple-tenancy setups where the goal is to run a single coaxial cable to each unit and have the satellite TV and regular TV through the one cable. The reason I supported this idea is to allow for a broadcast-LAN setup working to SAT-IP standards to cater to most broadcast environments where content distributed via the satellites is different to content distributed via the regular TV infrastructure.
But the main benefit is that there is a step to a level playing field for satellite-based broadcast-LAN applications thus providing for competition and innovation in this application no matter the deployment type. It has opened up broadcast-LAN implementations like a Power-Over-Ethernet-powered LNB with integrated server which bolts on to the satellite dish and yields the broadcast streams to the home network from that dish; as well as a Grundig broadcast-LAN tuner with four front-ends and full DLNA capability.
The SAT-IP concept, along with the US goal for using broadcast-LAN to democratise the provision of cable TV is underscoring the reality of using the home network to distribute TV content around the home, whether this network uses Ethernet, Wi-Fi wireless or HomePlug AV powerline or a mix of the technologies. Here, this means no more chipping at delicate walls to run satellite cable around the home and you can view Sky on your iPad or Sony VAIO Duo 11.
