Envivio and TUXIA demonstrated an MPEG-4 enabled interactive IP TV set-top box at the National Association of Broadcasters (NAB) Conference this week in Las Vegas. The demo showcased hardware, software, and services for an end-to-end low-bandwidth IP TV solution, the companies said.

Specifically, Envivio's MPEG-4 video broadcast and streaming technologies were combined with TUXIA's “Purple TASTE” client software stack, and the two were integrated into GCT Allwell's IP-streaming set-top box. The latter accomplishes MPEG-4 decoding using Sigma Design's EM847x MPEG decoder, which provides ISMA-compliant video streaming, the companies said.

TUXIA describes its TASTE software as a customizable, Linux-based software stack for open standards based IP-streaming set-top boxes. TUXIA's componentized Linux embedded operating system makes use of an XML-based GUI on a Mozilla web browser.

Envivio says its technologies enable the capturing, encoding, and streaming live video content, provide media-on-demand services, and offer realtime control of multiple encoder and server components within IP TV content.
