摘要： A PSI converter includes: a protocol data extractor, a protocol data converter, a protocol data inserter, and a system controller. The protocol data extractor is configured for demultiplexing a terrestrial broadcasting TS or a satellite broadcasting TS, and extracting audio/video data and PSIP/PSI data or audio/video data and SI/PSI data from the terrestrial broadcasting TS or the satellite broadcasting TS, respectively. The protocol data converter is configured for converting the PSIP/PSI data or the SI/PSI data into PSIP/PSI data of a corresponding digital cable television broadcasting standard. The protocol data inserter is configured for inserting the digital cable television broadcasting standard PSIP/PSI data into the audio/video data extracted by the protocol data extractor though TS multiplexing, and generating a digital cable broadcasting TS. The system controller is configured for checking the protocol data extractor, the protocol data converter, and the protocol data inserter, and controlling their operation.

摘要： An apparatus and method for transmitting MPEG-4 data synchronized to MPEG-2 data is disclosed. The apparatus for transmitting MPEG-4 data synchronized to MPEG-2 data includes: an object separation unit for extracting MPEG-4 object data from MP4 data, separating meta information from the object data, and generating program information and synchronization information; a conversion unit for converting the MPEG-4 object data to MPEG-4 packets of which data structure is the same as that of MPEG-2 data, based on the program information and synchronization information; and a multiplexing unit for multiplexing the MPEG-4 packets with the MPEG-2 data.
