fig1 to transmit the cds 18 to the receiving device 22 of fig1 the transmission process of fig2 commences upon execution of the start step 200 during which the transmitter initializes itself if needed thereafter the transmitter 14 of fig2 combines the elementary data streams edss 16 1 and 16 2 into the cds 18 during step 202 of fig2 during step 202 the transmitter 14 will compress and or encode the cds 18 if necessary using one of a variety of known techniques finally the transmitter 14 transmits the cds 18 over the link 20 at the cbr to the receiving device 22 of fig1 during step 204 of fig2 after which the transmission process ends step 206 referring to fig1 the receiving device 22 processes the cds 18 to yield an output data stream 23 for rendering such as for display on a display device not shown or for processing by a codec not shown or other device as discussed in greater detail hereinafter the receiving device 22 advantageously buffers each byte in a buffer 24 for at least a brief interval before processing to achieve synchronization in that regard the receiving device 22 includes a clock and phase lock loop circuit 26 for synchronizing the processing of each eds e g edss 16 1 and 16 2 following de multiplexing of the cds 18 as discussed above the transmitter 14 will typically compress and or encode the cds 18 transmitted to the receiving device 22 for that reason the receiving device includes circuitry 28 for decoding and or de compressing the bytes in the de multiplexed bit stream fig3 depicts in flow chart form the steps of a process.
