摘要： A method of formatting a digital broadcast transport stream packet, a digital broadcast transmitter, and a signal processing method thereof, includes constructing a transport stream packet that includes a stuffing region for an insertion of a known supplementary reference signal (SRS) data therein, randomizing the packet that includes the stuffing region is randomized, and the SRS data is inserted into the stuffing region of the randomized packet. Adding a parity for an error correction to the packet into which the SRS data has been inserted, the packet to which the parity has been added is interleaved, and a trellis encoding of the interleaved packet is performed. Inserting a segment sync signal and a field sync signal into the trellis-encoded packet, and a vestigial side band (VSB) modulation and an RF conversion of the packet are performed to transmit the VSB-modulated and RF-converted packet.

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.
