ABSTRACT:
The invention relates to a C block generator for generating the C bits for a plurality of devices using the AES/EBU format. The C block generator preferably comprises an eight switch dip switch for selecting a desired one out of 256 possible C block sequences. The dip switch is connected to the upper eight bits of an EPROM's address input for indicating to the EPROM which sequence has been selected. The lower eight bits of the EPROM's address input are connected to an eight bit binary counter which is reset at the initiation of the transmission of each block. The EPROM uses the count from the counter to indicate which bit will be generated out of the selected sequence. Thus, as the count progresses, the generation of the sequence of C bits progresses in synchronism. The invention allows an operator to easily change the C block by simply opening or closing the appropriate switches on the dip switch. The invention also simplifies the design of systems using the AES/EBU format since a single C block may be used to generate the C bits for a plurality of devices.
