ABSTRACT:
An apparatus and a method for packetizing a coded bitstream of digital data in accordance with a transport protocol. Packetizer receives MPEG4 stream from an encoder and translates it into MPEG2-PEG packet. A multiplexer receives the stream of the MPEG2-PEG packet form and transports a stream of MPEG2-TS form as a transport output signal. The packetizer detects a header from the MPEG4 stream and analyzes the header to obtain predetermined information from Video_Object_Layer header and Video_Object_Plane header. The packetizer generates the time information such as ESCR, DTS, and PTS using the predetermined information and an initial value of ESCR supplied from outside. The PES header including such time information is generated. The packetizer further generates the MPEG2-PES packet in sequence with the generated PES header added into every AU of the MPEG4 stream and obtains the stream of MPEG2-PEG packet form.
