Abstract
Apparatus for inserting synchronizing data between blocks of serial data and for subsequently retrieving said blocks of data in the correct sequence and at the right point in time. The apparatus for inserting the synchronizing data synchronizing data generating means for producing a predetermined data sequence. Selector means are connected to the data generator and also to an input receiving the serial data for selecting either the serial data or the synchronizing data. Control means are connected to an output of the selector means for producing an identification gap in the serial data before the start of the synchronizing data. The signal produced at an output of the control means comprises a data gap followed by the synchronizing data and the serial data. The apparatus for retrieving the blocks of serial data from these signals comprises synchronizing data detection means for detecting the predetermined data sequence including the identification gap. Extractor means are provided to separate the data blocks from the synchronizing data. Control means are also provided for controlling the extractor means to inhibit extraction of the data if the synchronizing data detected is of an incorrect sequence.
