Nuvation’s Intelligent Video Server (IVS) is a reference design for a single-channel audio/video encode/decode streamer which can adapt a standard CCTV analog camera into an Internet Protocol (IP) streamer. IVS can also be utilized as an A/V decoder.
The reference design features TI’s DaVinci™ DM6446 DSP, TI Digital Media software codecs, Embedded Linux, optional video analytics, and a compact mechanical enclosure.

Hardware Architecture
System 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.
Within the DaVinci™, the incoming BT.656 video stream is processed by the Video Processing Front End (VPFE) and sent to the C64+ DSP for encoding. The DSP encodes it with the chosen video codec and passes the data back to the ARM. The ARM then packetizes the data using the RTP/RTSP over UDP/TCP protocol and sends the stream to the Ethernet PHY chip for transmission over the network.
A web server running on the ARM within the DaVinci™ allows users on the network to configure IVS settings through a browser utility.
