Ancillary Data and the Serial Digital Interface

The previous tutorial in this series discussed EDH (error detection and handling). The EDH information is inserted into the serial data stream as ancillary data. Other signals, such as digital audio and time code, have also found their place as an ancillary data type. Signal source identification and closed captioning would be the next two obvious candidates for standardization. Now that many signals can be carried along a single coaxial, there are benefits to the broadcaster. As digital audio signals can be embedded into the serial video signal, a review of digital audio is in order.
