SMSC High-Performance Multimedia Co-Processor, Featuring RipStream Technology
     
LAN9131
     
High-Performance Multimedia Co-Processor, Featuring RipStream™ Technology
     

SMSC High-Performance Multimedia Co-Processor, Featuring RipStream TechnologyIndustry’s first high-performance, wired 10/100 network multimedia co-processor employing RipStream technology, which combines support for multiple high-definition (HD) streams,software protocol stack management and security. The LAN9131 co-processor allows system designers to leverage existing SoC and host processor-based designs that support Digital Living Network Alliance™ guidelines with minimal design risk and fast time-to-market.
 
Highlights:
•
 RipStream technology supporting DLNA guidelines
 
•
 Supports multiple HD video streams
 
•
 Built-in UPnP, HTTP, TCP/IP protocol stack
 
•
 Integrated 128-bit AES encryption/decryption for Digital Rights Management (DRM)
   
-
 Supports Windows® Media DRM10 (WMDRM 10)
   
-
 Supports Digital Transmission Content Protection over Internet Protocol (DTCP-IP)
   
-
 Fast DTCP-IP AKE key exchange time (0.6 sec.)
   
•
 Two Transport Stream Interfaces (TSIs) to MPEG encoder/decoder SoCs
 
•
 Either interface can be used in server or rendering applications
     
•
 Video codec agnostic
    Supports MPEG2, MPEG4, WMV9/VC-1, H.264/AVC
   
•
 Integrated ARM926™ core
   
•
 Integrated 10/100 MAC/PHY with HP Auto-MDIX and multiple power management modes
   
•
 TCP/UDP checksum offload
   
Features Benefits
RipStream technology combines
support of multiple HD streams, software protocol stack management and security		 High throughput; two HD MPEG2 or multiple MPEG4 streams
Two bidirectional TSI ports which directly interface to videoprocessing functions Overcomes system host bus imitations. High bandwidth audio/video HD streams can be handled without burdening system host bus. Ports support extended modes with flow control and allow transfer of non-MPEG2 TS formats.
Integrated 10/100 MAC/PHY with HP Auto-MDIX Complete networking solution that eliminates the need for special “crossover” cables when connecting LAN devices together
Crypto block supports both DTCP-IP
and WMDRM 10		 Provides DRM copyright protection. Flexible support for major industry standards; eliminates need for separate crypto device.
Video codec agnostic Handles any video codec (MPEG2, MPEG4, WMV9/VC-1, H.264/AVC)
Can boot from Flash memory or host processor Reduces need for additional components
Integrated DLNA, UPnP and TCP/IP stacks Consumer Electronics interoperability; ability to recognize other UPnP devices and offload host TCP/IP implementation
Highly flexible software architecture; customer can decide whether LAN9131 or host runs UPnP stack Allows ease of integration to various architectures; allows system designer to optimize the architecture to application needs
