RTD, represented in Australia by Allied Data Systems , has introduced a range of frame grabbers with up to 8 composite or 4 S-video inputs supporting NTSC, SECAM, and PAL. input formats.
Video inputs connect with SMB snap lock or 0.1-inch DIL connectors. Stereo audio I/O can be interfaced with 0.1-inch DIL connectors.
Dual independent channels support audio and video capture of simultaneous A/V input streams. Multiplexed video inputs on each channel switches independently per user specification.
Hardware MPEG-2 compression is available on selected modules and requires no specialised software libraries. Compression can be enabled or disabled independently on each channel reducing storage and PCI bandwidth requirements for video and audio data.
Philips’ SAA6752HS MPEG-2 compression chip supports 1.5 to 25Mb/s output data rates in constant or variable bit rate modes giving maximum application flexibility.
Frame Grabber modules include 8 general purpose I/O lines supporting 4 opto-coupled digital inputs and 4 opto-coupled digital outputs.
Opto-isolated digital I/O allows the Video Frame Grabber to interface with control equipment in the presence of high voltages and current loops.
