Method of and apparatus for converting data stream format and method of and apparatus for recording data stream using the method and apparatus

摘要

A method of and apparatus for converting a program stream (PS) into a transport stream (TS) and a method of and apparatus for recording a data stream using the method and apparatus are provided. The method for converting the PS includes extracting a system clock reference (SCR) and a program mux rate; extracting a stream identifier (ID) from a packetized elementary stream (PES) packet header; identifying a data type of PES packets using the stream identifier (ID); dividing the PES packets according to a payload size of a TS packet if the identified data type is video or audio data; generating consecutive TS packets by adding a TS pack header to each of the divided PES packets; and setting a program clock reference (PCR) of an adaptation field included in a TS packet header of the first generated TS packet equal to the extracted SCR.
