APPARATUS AND METHOD FOR GENERATING AN MPEG-2 TRANSPORT PACKET HAVING A VARIABLE PACKET LENGTH

摘要

The present invention proposes a transport packet generating apparatus for generating a transport packet having a variable length, wherein a header of the transport packet contains a field area indicating the length of the transport packet, or wherein the length of the transport packet is indicated using a synchronization area of the transport packet. In addition, the present invention proposes a depacketizer which interprets the field area indicating the length of the transport packet, or searches for and interprets the start point of the transport packet in accordance with a predetermined regulation on a synchronization area, so as to depacketize a transport packet having a variable length.
