Network multimedia co-processor supports multiple high-definition A/V streams


Hauppauge, N.Y.—Aimed at network-enabled HDTV, set-top boxes, digital video recorders and home media servers, Standard Microsystems Corp. has released the LAN9131 network multimedia co-processor based on RipStream technology that combines support of multiple high-definition (HD) A/V streams, software protocol stack management and security.

The LAN9131 is video codec agnostic, supporting MPEG2, MPEG4, WMV9/VC-1 and H.264/AVC standards. It provides A/V streaming over Ethernet with support for multiple HD streams, as well as support for UPnP protocols, including HTTPU, HTTPMU, GENA, SOAP, XML and SSDP.

It is said to be the only wired Ethernet co-processor that supports Digital Living Network Alliance (DLNA) guidelines. For more on DNLA, click here:

The LAN9131 interfaces to most 32- and 16-bit embedded CPU buses, and integrates a 10/100 Ethernet Mac/PHY.

The LAN9131 leverages the 32-bit ARM926 core to offload the main SoC's high TCP/IP processing burden while supporting multiple HD A/V streams with what the company claims are the fastest Fast Ethernet data rates available. The main SoC can now partition out CPU intensive networking, interoperability and content-protection functions to the LAN9131 co-processor, allowing the SoC to focus its finite resources on core multimedia and user interface applications.

Additional offloading from the main SoC is achieved through two dedicated bi-directional Transport Stream Interfaces (TSIs), enabling the LAN9131 multimedia co-processor to assign both audio and video packets without interfering with the main SoC's system bus.

The LAN9131 is sampling now with production volumes expected in the first quarter of 2007. Pricing for the LAN9131 is expected to be in the sub-$18 range per unit in OEM quantities.
