Patent ID: 7324560

Claim:
A method for transmitting a digital data stream, in which method data clock information and data frame information are recovered from the digital data stream, the method comprising: providing a digital data stream having successive data stream units, each data stream unit including a data frame, a data block having data bits, and a frame synchronization word having frame synchronization bits; wherein a frame start of a data frame is defined when a plurality of dummy bits precedes a frame synchronization word, the plurality being at least one greater than the sum of the number of frame synchronization bits in the frame synchronization word and the number of data bits in the data block; receiving the digital data stream; detecting successive frame synchronization words of the successive data stream units; determining the data clock information from a temporal spacing of the successive frame synchronization words; and outputting the data clock information in a manner dependent on a temporal spacing of successive frame synchronization bits.
