DLNA router technology runs Linux

Jan 7, 2009 — by Eric Brown — from the LinuxDevices Archive — 5 views

At CES, fabless chip-maker Mindspeed Technologies will demonstrate a prototype of a consumer DLNA router that combines its Comcerto 100 broadband processor with Wind River's Platform for Consumer Devices, Linux Edition. The media sharing demonstration will also feature DigiOn's DiXiM Media Server (DMS), says Mindpeed.

The demonstration will show a broadband home router using Digital Living Network Alliance (DLNA) technology that shares and streams digital media from a variety of TVs, set-top boxes (STBs), computers, and gaming consoles across a home network. The integrated product can even share files that are saved on non-DLNA-enabled storage devices, claims the company, although it does not describe how the router would be able to discover such resources.

In June, Wind River announced plans to port Wind River Linux to Mindspeed's Comcerto 100. Announced in mid-2007, the Comcerto 100 is based on dual ARM11 cores clocked at 450MHz. According to Mindspeed, the packet processor also integrates “a security engine, 64KB of on-chip memory, 128KB of L2 cache, a 64-bit-wide, 165MHz multi-layer interconnect bus, and built-in QoS and traffic-management capabilities.” Different configurations of the chip variously target VoIP, Fast Ethernet broadband routers, gigabit Ethernet broadband routers, and ATM routers.

Currently, the typical software configuration for the chip is to run the OpenWRT Linux distribution on one core, and MindSpeed's binary-licensed “media stream processor” executive on the other. The Wind River port gives customers the option of instead using Wind River's “optimized platforms” on one or both cores. Wind River's Platform for Consumer Electronics is one of a growing list of Wind River commercial embedded Linux platforms. Introduced in 2005, it targets mobile phones, STBs, digital video recorders (DVRs), and other small-footprint consumer electronics devices.

DigiOn's DiXiM Media Server (DMS) offers “DLNA guideline qualified” media server capabilities, says the company. Features are said to include content discovery services (CDS), AutoSync, content distribution, upload, and a DTCP-IP encrypted distribution option.

Stated Preet Virk, SVP and GM for Mindspeed's CPE products, “Our Comcerto 100 low-power packet processor combined with industry leading DigiOn's DMS software and Wind River's Linux platform, enables us to deliver an off-the-shelf solution to our customers targeting the next-generation consumer electronic devices where media sharing capabilities are a must!”

Mindspeed did not mention when a router combining the three technologies might appear. The DLNA router technology demonstration will take place starting tomorrow at the 2009 International Consumer Electronics Show in Las Vegas, Nev. at Mindspeed's booth, South Hall 1, Las Vegas Convention Center, booth 21828.
