Precise multiplexed transmission and reception of analog and digital data through a narrow-band channel

摘要

A data transfer system is described for transferring analog data from a source to a destination by treating the analog data as a continuous series of segments sequentially compressing segments of the analog data and then multiplexing the compressed analog data with analog encoded digital data including synchronization data. The resultant multiplexed data stream is then provided to a data channel for transfer. The synchronization data included with the analog encoded digital data is used to resynchronize the demultiplexer of a receiver receiving the multiplexed data stream. The analog encoded digital data is demultiplexed and demodulated while the analog data is decompressed to realize again the continuous analog data stream as originally provided to the data source.
