DMB TX/RX APPARATUS AND METHOD FOR TRANSMITTING SUPPLEMENT DATA BY IDLE BAND OF VIDEO SERVICE

摘要

PURPOSE: A DMB transceiving apparatus for transmitting additional data by an idle band of a video service and a method thereof are provided to insert additional data to a null packet of video service data encoded in a video multiplexing unit. CONSTITUTION: A video multiplexing unit(220) receives additional data from a data encoder(218). The video multiplexing unit receives encoded video service data from a video encoder(214). The video multiplexing unit detects a null packet from the encoded video service data. The video multiplexing unit inserts the additional data into a payload of the null packet. An ensemble multiplexing unit(230) multiplexes the encoded data by an ensemble signal.
