Abstract:
Data processing apparatus for receiving and processing a transport stream of packets for allowing simultaneous recording of the transport stream by a recording apparatus and reproduction from the recorded transport stream, comprising:(a) a multiplexer; (b) an input PID parser in communication with said multiplexer and the recording apparatus for selecting different types of packets included in a transport stream, comprising an input for receiving packets from said transport stream, a first output for outputting recording/controlling packets from said transport stream to said multiplexer, and a second output for outputting recording packets and said recording/controlling packets to the recording apparatus; and (c) an output PID parser in communication with the recording apparatus and said multiplexer for selecting different types of packets included in a reproduced transport stream, comprising an input for receiving packets from a reproduced transport stream of packets reproduced from the recording apparatus, said reproduced transport stream including prerecorded data packets corresponding to said recording packets and prerecorded recording/controlling packets corresponding to said recording/controlling packets, and an output for supplying said prerecorded data packets and said prerecorded recording/controlling packets to said multiplexer, wherein said multiplexer multiplexes said recording/controlling packets, said prerecorded data packets and said prerecorded recording/controlling packets to form an output transport stream of packets.
