Not sure it is a network system. The company promoting it is Valens Semiconductor who make the first chipset ( RX and a TX). From the front page of their website
Valens’ HDBaseT™ is the first technology to enable long-reach wired connectivity of uncompressed HD multimedia content via a single LAN cable. Valens chips transfer uncompressed HD video, audio and Internet via up to 100m/328ft low-cost LAN cable. This enables both point-to-point connectivity and full multimedia distribution with higher reliability, longer distance and lower cost cable - perfectly answering the needs of the end user.
Valens’ HDBaseT delivers significant value to the entire home entertainment ecosystem, from Consumer Electronics (CE)/PC equipment manufacturers and audio/video connectivity product suppliers, through systems integrators and retailers, to installers and consumers.
HDBaseT enables the next evolution of HD video and data connectivity and distribution in the home by offering a unique feature set that:
* Enables 5Play™ – video, audio, Internet, power over cable and various controls signals which are all critical in order to provide the point-to-point connectivity and multimedia distribution in a HD home entertainment environment.
* Reduces the number of ports – one port for HD video, audio and Internet, instead of two.
* Solves the customer’s need for performance over longer distance, ease of installation, reliability, flexibility and cost of installation.
* Leverages the distribution of HD content with new applications.
* Enables, for the first time, an HD distribution system based on CE devices. PC-based media servers are no longer required and CE devices are once again the emperors of the living room.
