Nuvation’s Intelligent Video Server (IVS) is a reference design for a 1-channel audio/video encode/decode streamer which can adapt a standard CCTV analog camera into an Internet Protocol (IP) streamer. The reference design features TI’s DaVinci™ DM357 DSP with TI video codecs, G.711 audio codec, Embedded Linux, and a compact mechanical enclosure.

	1-channel audio/video encode/decode streamer over TCP/IP Can be run in Encode mode, or Decode mode 30 frames per second, D1 resolution TI DaVinci™ DM357 Dual-Core DSP with ARM926 H.264 BP, MPEG-4 SP, and MJPEG video codecs Supports unicast and multicast Supports audio mic interface and G.711 audio encode/decode 10/100 Ethernet TCP/IP compressed video stream Power-over-Ethernet 802.3af-compliant PD controller with integrated DC/DC converter Real-Time Embedded Linux Encoded audio/video stream can be decoded on any networked PC running software such as QuickTime or VLC Player Encoded audio/video can also be decoded with IVS and displayed on an attached monitor in decode mode. Browser-based utility allows configuration of settings and parameters RTP/RTSP over UDP/TCP transport Compact form factor 12V DC, 4.5W max RoHS compliant Available as evaluation unit or production license with fully licensable design

Hardware Architecture

An external video/audio source (eg. camera) can be connected to the IVS through to stream the video on a network.  The source is connected through the IVS front panel.  Video and audio connect directly to the AVIO board inside the IVS. 

The AVIO board receives composite video through a BNC connector.  Able to decode both NTSC and PAL video formats, a TVP5146 video decoder converts the video to 10-bit BT.656 and sends it to a TI DaVinci™ processor on the Encoder board.  The video output connector passes NTSC / PAL analog video received from the DaVinci™ processor.  Stereo audio input, output, and mic connections run through an audio codec, and on to a bi-directional I²S bus to the DaVinci™ processor. Both the video and audio codecs are controlled through an I²C interface.

Software Architecture



Software & Drivers

• Runs Montavista Linux with TI DaVinci™driver support
• Encoder firmware application that encodes/decodes audio-video streams in real-time
• Decoder comes with audio-video synchronizing mechanisms for proper playback
• thttpd lightweight web server runs a browser utility for easy camera configuration
• Driver support for USB, video, audio and UART RS-232 communication

TI DaVinci™ DM357 Software Options

• Pre-programmed codecs:
• H.264 BP encode/decode
• MJPEG encode/decode
• G.711 encode/decode
• IVS is pre-programmed with embedded Linux 2.6 with real-time extensions, running on a ARM926 coprocessor within the DaVinci™
• MPEG-4 SP is pre-programmed in the DM357 and can be brought out to the browser UI controls with design customization
• Alarm IO, PTZ, and other features can be added with design customizations

• The Fixed-Function Coprocessor runs the complex algorithms required to encode the raw video into the various video codec formats
• The ARM is responsible for managing the digital video interface and the web server
