The DRS system also includes an optioncard for embedding (MUX-3G Card) digital audio with SDI video to marry the videorouting capability of the Cheetah Video Matrix Routers with the audio routingcapability of the Cheetah DRS Audio Router. The DRS MUX card is compatible withSDI video signals up to 3Gbps and compliant with SMPTE 259M, 292M and 424M. Audio may be embedded to a SD/HD/3G-SDI signal.

The Cheetah MUX-3G card provides 16 SD/HD/3G-SDI video output channels andembeds any of up to 256 audio signals selected from DRS input sources to any ofthe SD/HD/3G-SDI video output signals. Any audio input signal to DRS – AES,embedded, MADI or analog – can become the input source for the video MUX cardfor embedding onto a video output signal. In DRS system configuration-theMUX-3G card functions as a signal output frame. Full digital signal processing andstereo remedies may be applied to embedded audio signals.
