Abstract
A method of converting format from a transport stream (TS) to a file for storing television program data carried by the transport stream includes steps of receiving a transport stream, performing filtering and depacketizing process for the transport stream to generate a plurality of elementary streams (ES) and presentation time stamps (PTS) corresponding to each data unit of the plurality of elementary streams according to packet identifiers (PID) of television programs being recorded, and converting the plurality of elementary streams to a file according to the presentation time stamps.
Claims27
A method of converting a transport stream into a file, for storing television program data carried by the transport stream, the method comprising:
- receiving the transport stream;
- performing filtering and depacketizing processes on the transport stream according to a plurality of packet identifiers (PID) of television programs to be stored to generate a plurality of Elementary Streams (ES) and Presentation Time Stamps (PTS) corresponding to each data unit of the plurality of elementary streams;
- and
- converting the plurality of elementary streams to the file according to the presentation time stamps.
An electronic device for converting a transport stream into a file, for storing television program data carried by the transport stream, the electronic device comprising:
- a reception terminal for receiving the transport stream;
- a filtering unit, coupled to the reception terminal, for performing filtering and depacketizing processes on the transport stream according to a plurality of packet identifiers (PID) of television programs to be stored to generate a plurality of Elementary Streams (ES) and Presentation Time Stamps (PTS) corresponding to each data unit of the plurality of elementary streams;
- a file wrapping unit, coupled to the filtering unit, for converting the plurality of elementary streams to the file according to the presentation time stamps;
- and
- an output terminal, coupled to the file wrapping unit, for outputting the file.
A digital television reception device having a television recording function, the digital television reception device comprising:
- a television receiver, for receiving a digital television signal to generate a transport stream;
- a stream to file converter, coupled to the television receiver, for converting the transport stream to a file for storing television program data carried by the transport stream, the stream to file converter comprising:
- a filtering unit, for performing filtering and depacketizing processes on the transport stream according to a plurality of packet identifiers (PID) of television programs to be stored to generate a plurality of Elementary Streams (ES) and Presentation Time Stamps (PTS) corresponding to each data unit of the plurality of elementary streams;
- and
- a file wrapping unit for converting the plurality of elementary streams to the file according to the presentation time stamps;
- and
- a file storage device, coupled to the stream to file converter, for storing the file outputted by the stream to file converter.
