Louisville, Colo. - Cable TV industry-standards body
said it recently gathered 37 participants from 11 companies to demonstrate the next phase in Tru2way/Digital Living Network Alliance (DLNA) interoperability.
The event demonstrated sharing of premium DVR content among multiple Tru2way set-top boxes and DLNA-certified devices, such as connected TVs, game consoles, PCs and mobile devices, over a home network in a secure manner.
"Providing an environment where cable and consumer electronics manufacturers can work with each other and solve problems to advance home entertainment networking technologies is a valuable service that CableLabs provides to the industry," stated Paul Liao, CableLabs president and CEO.
Set-top manufacturers attending the showcase included ADB, Cisco, Samsung Electronics and Motorola; they were joined by such DLNA-certified device manufacturers as Panasonic, Samsung and Sony, and DLNA technology component vendors including Microsoft, Cyberlink, Irdeto, Myriad and NDS.
Program guides with multi-room DVR capability from Cox (Trio) and Time Warner Cable (OCAP Digital Navigator v.4.0) were also used in the demonstrations, CableLabs said.
The event followed CableLabs' recent revision of the home-networking extension specification and associated reference implementation that is part of the Tru2way suite of specifications.
CableLabs said it believes that integrating home networking into the overall specification "enhances the Tru2way platform, making premium content sharing possible among multiple set-top boxes and DLNA-certified devices within a home network."
The DLNA interoperability guidelines are the foundation of Tru2way home-networking specifications. The premium cable content is protected using DTCP-IP as it is transmitted over the home network.
"By using the Tru2way home-networking specification we can now offer pre-recorded premium content from cable set-top boxes to various DLNA-certified devices, enabling consumers to watch cable content anytime using any device in the home" said Mike Hayashi, Time Warner Cable advanced engineering executive VP.
"Now a Cox cable consumer can utilize Cox's Trio guide to record an event on the DVR in the family room and access it later from the bedroom television, thus enabling the promise of multi-room DVR capability," said Craig Smithpeters, Cox Communications interactive services engineering executive director.
Content sharing among set-top boxes is enabled via a Multimedia over Coax Alliance (MoCA) 1.1 network that utilizes in-home coax wiring, thus alleviating the need to run new wiring within the home. MoCA can support multiple streams of HD video and offers 175Mbps of throughput.
