A receiver is provided for receiving a digital data stream over a communication path. The digital data is arranged as a sequence of frames, each frame including a plurality of lines of data. The beginning of each frame is indicated by a frame synchronization word; the beginning of each line is indicated by a horizontal synchronization byte. The data is interleaved by an encoder prior to transmission. The decoder contains circuitry for locating the horizontal and frame synchronization data and contains circuitry for deinterleaving the digital data. Both the synchronization locating circuitry and the deinterleaving circuitry require access to a memory, but not at the same time. Therefore, a single memory is used with the synchronization recovery circuitry and deinterleaving circuitry alternately addressing the memory.

Memory efficient method and apparatus for sync detection

An apparatus for transmitting a multiplexed analog component television signal. The apparatus includes a signal source generator for generating a signal source having information regarding the number of lines per frame. A multiplexed analog component television signal generator generates a multiplexed analog component television signal having a varying number of lines per frame and including information regarding the number of lines per frame. A transmitter coupled to the multiplexed analog component television signal generator transmits the television signal to at least one remote terminal.
