Abstract
Technique for Routing digital audio and digital video signals commences by routing a digital video signal, devoid of embedded digital audio, to at least one output, typically by way of a video cross-point switch. At least one digital audio signal undergoes buffering to obtain a prescribed amount of data prior re-timing of the digital audio signal to a prescribed timing format. Following buffering and re-timing, the digital audio signal undergoes routing to at least one output, typically by way of an audio cross-point switch. When routed to outputs associated with each other, the digital audio signal undergoes embedding in the digital video.
