In addition to standard signal I/O frames, the DRS system also includes two special purpose circuit cards for de-embedding (DEMUX-3G Card) and embedding (MUX-3G Card) digital audio with SDI video that marry the video routing capability of the Cheetah Video Matrix Routers with the audio routing capability of the Cheetah DRS Audio Router. Both cards are fully compatible with SDI video signals up to 3Gbps and compliant with SMPTE 259M, 292M and 424M. These cards are used in place of the HD/3G-SDI video input buffer and video output combiner cards in a Cheetah video router mainframe. The audio portion of each card integrates with a DRS channel group through an available E-DXE I/O port using common CAT5E cable, up to 100M in length.
The Cheetah DEMUX-3G card provides 16 SDI video inputs and de-embeds all audio groups and channels from all sixteen video signals. Up to 128 de-embedded audio signals may be selected as input sources for the DRS channel group. The Cheetah MUX-3G card provides 16 SDI video output channels and embeds any of up to 128 audio signals selected from DRS input sources onto any of the sixteen video output signals. Any audio input signal to DRS – AES, embedded, MADI or analog – can become the input source for the video MUX card for embedding onto a video output signal. In DRS system configuration, the DEMUX-3G card functions as a signal input frame, and the MUX-3G card functions as a signal output frame. Full digital signal processing and stereo remedies may be applied to any or all embedded audio signals.
