Comcast and Cox Communications showed off HTML5-based program guides that supported playback of linear TV content across a range of IP-based devices at a recent CableLabs tru2way interoperability event.
The CableLabs tru2way Home Networking interoperability event -- the third in a series of events -- was held at CableLabs' Louisville, Colo., headquarters from April 30 to May 4, 2012.
Device manufacturers that participated in the event included Humax, Samsung Electronics, Sony Computer Entertainment America -- which makes the PlayStation 3 -- and Sony Electronics.
Digital Living Network Alliance (DLNA) technology component suppliers included Access Systems, Groupo Communications, Myriad Group and PacketVideo. Tru2way host device manufacturers were represented by Cisco Systems, while Silicondust provided an OpenCable unidirectional receiver device.
The interop's participants demonstrated delivery of premium cable content between IP-based DLNA client services, including early implementations of HTML5-based clients and cable operator-supplied Remote User Interface (RUI) program guides. The content was securely shared over the home network using DTCP-IP link protection.
In addition, Comcast, Time Warner Cable and Cox provided program guides that integrated tru2way technology with multiroom DVR capability.
During the event, Comcast demonstrated its HTML5 RUI running in an HTML5-based browser and streaming linear content to early implementations of HTML5-based clients, according to Steve Reynolds, Comcast's senior vice president of premises technology.
The CableLabs tru2way reference implementation also participated as both a client device and a tru2way Host Device in the multivendor interoperability scenarios. The tru2way reference implementation software is maintained by CableLabs with support from the open-source community on java.net and integrated into tru2way devices by manufacturers.
The CableLabs Home Networking events "continue to provide value in advancing interoperability between the growing list of tru2way Host Devices and DLNA-based home networking devices," Mike Hayashi, executive vice president of architecture, development and engineering for Time Warner Cable, said in a statement.
