Method for transmitting synchronization data in audio and/or video processing systems

摘要

A method for transmitting synchronization data in an audio and/or video processing system that supports digital two-channel audio transmission between a control center and at least one remote station is disclosed. The synchronization data include speech information and control information. The speech information is transmitted over a first channel and the control information is transmitted as an analog audio signal over the second channel of the two channel transmission path.
