Linux-based media stack for TI’s DaVinci launched

Jan 10, 2008 — by Eric Brown — from the LinuxDevices Archive — 4 views

A developer of Linux-based, IP-media applications formally launched its software for Texas Instruments's DaVinci media processor platform. DigiLink Software says its Digital Media Elements (DME) IP-media stack for set-top boxes (STBs) lets television viewers watch and record Internet TV… (ITV), including Flash-based content like YouTube.

The DME stack has previously been demonstrated on DaVinci processors, but apparently not formally offered as a standalone product. DigiLink, based in Beijing and Irvine, Calif., says it has hired consulting firm 3D Incorporated to help it market the DME stack.

The previous demonstration of DME on DaVinci came last November, when DigiLink teamed up with set-top box design house Visioneering on a hardware/software reference design. The design featured Digilink's DME codecs and DME-FLV media player running atop MontaVista Linux on Visioneering compact “Sonata” STB. The Sonata is based on TI's DaVinci TMS320DM6446 processor.

The Sonata-based design can display high-definition multimedia content up to 720p resolution, and supports H.264, WM9, VC-1, MPEG4, MPEG2, and other codecs. Options include 802.11g WiFi, videoconferencing, video capture, and digital video recording (DVR) capabilities. DigiLink says the design could also be used in other embedded applications, including Internet TVs, digital media adapters, and portable media players (PMPs).

Stated Dr. Karl Zhao, President of DigiLink, “We believe that TI's DaVinci DSPs provide a mainstream, unified platform. With the cooperation from 3D, DigiLink is ready to embrace the consumer electronics market directly.”
