Abstract
A digital data transmission system comprises at its input a higher order multiplexer receiving at least one stream of digitized data organized into blocks and at a specific timing, said multiplexer transmitting each block of data in a digital multiplex to the output of the transmission system via a digitized data transmission channel subject to a variable multiplexing delay. To reduce the low-frequency component of the jitter in a timing signal reconstituted at the output of the system, the multiplexing delay is measured for the current transmission of a block of data in the multiplex and the measured multiplexing delay is compared with a reference value to determine a multiplexing delay offset and if necessary to defer said current transmission. The measurement and comparison are repeated for the next transmission of a block of data in the multiplex using in the comparison the multiplexing offsets determined for previous transmissions.
