Video Capture and Compression Adapter
Advance

PDF print version of this specification : A4 or Letter

 The CI Systems Video Capture and Compression Adapter generates a compressed video data stream from a standard RS-170 video source using MPEG4 compression implemented in hardware.

This compressed video data stream can be output directly on one of four high-speed serial output channels or passed to a host computer via the PCI bus.

The Video Compression Adapter is available in the following industry standard compliant formfactors :

  • PMC
  • Air-cooled PMC with frontpanel I/O (IEEE Std 1386.1-2001)
  • Conduction-Cooled PMC (CCPMC) with backplane I/O (ANSI/VITA 20-2001)

Architecture

RS-170 (NTSC) Video is decoded by a Techwell TW9900 Video Decoder and the resulting IUT-R BT.656/601 video is compressed by an INTIME IME6500 MPEG4 Codec. The IME6500 features an integrated RISC processor core as well as a DSP core to enable real-time operation, as well as uploadable firmware allowing customised solutions for specific applications.

The MPEG4 data stream is available via the PCI host interface, and can also be transmitted via one of the four RS-422 or RS-485 High-Speed Serial channels which operate at a maximum of 20 Mbit/s each. When not used for video transfer, High-Speed Serial channels are available for data transfer via the PCI host interface. The dedicated Communications Processor contained within the Motorola PowerQUICC II processor ensures that all four High-Speed Channels operate at full capacity while the main processor transfers video.

Features

  • Unbalanced 75 ohm or balanced 150 ohm Video I/O

  • IME 6500 Multi-Channel MPEG4 Codec with uploadable microcode for high flexibility
