SMSC Unveils First Network Multimedia Co-Processor For Streaming HD Media Content

Today, SMSC introduced its LAN9131, the industry's first high-performance network multimedia co-processor. Based on RipStream technology, which combines support of multiple high-definition audio/video streams, software protocol stack management and security, this solution delivers time-to-market advantages and reduces development risk for customer designs. Target applications include network-enabled HD TVs, set-top boxes, digital video recorders and home media servers, among others.

The LAN9131 offers support for the interoperability standards and is the only wired Ethernet co-processor solution to currently support Digital Living Network Alliance (DLNA) guidelines.

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 Fast Ethernet data rates. 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 the LAN9131's implementation of two dedicated bi-directional Transport Stream Interfaces (TSIs). This enables the multimedia co-processor to assign both audio and video packets without interfering with the main SoC's system bus. Also, the LAN9131's hardware-based AES-128 function block accelerates Digital Rights Management (DRM) content protection schemes such as Digital Transmission Content Protection over Internet Protocol (DTCP-IP) and Windows Media DRM (WMDRM 10) without burdening the main SoC.

Key Features:

  • Supports MPEG2, MPEG4, WMV9/VC-1, H.264/AVC
  • Audio & Video streaming over Ethernet with support for multiple HD streams
  • Support for UPnP protocols: HTTPU, HTTPMU, GENA, SOAP, XML and SSDP
  • SMSC custom API run-time libraries and drivers for host CPU communications
  • Interfaces to most 32- and 16-bit Embedded CPU busses
  • Embedded Linux OS with full support for networking applications
  • Integrated 10/100 Ethernet MAC/PHY
  • 256-pin XTQFP

The LAN9131 engineering samples are available today. Qualification samples are expected to be available in December 2006 with mass production samples in the first quarter of calendar 2007.
