Abstract
In a video TS packet separator, a video TS packet VTSP is extracted from a TS (transport stream). In a PES packet analyzer through a TS packet generator, the video TS packet is decoded, re-encodes at a predetermined bit rate, TS-packetized and supplied to a switch input terminal. The switch input terminal is also supplied with non-video TS packets UVTSP from a TS packet buffer. A controller is provided to control the TS packet generator and switch based on timing information and PCR from a TS packet timing manager. Thus, codes in the TS can be converted.
Claims9
A transcoder for transcoding a first video stream into a second video stream, comprising:
- a separator configured to extract a video transport stream packet including the first video stream, an non-video transport stream packet and timing information from a first transport stream;
- a memory configured to store the timing information;
- a conversion unit configured to generate the second video stream based on the first video stream;
- and
- a multiplexer configured to multiplex a video transport stream packet including the second video stream and the non-video transport stream packet based on the stored timing information to generate a second transport stream.
A transcoder for transcoding a first video stream into a second video stream, comprising:
- means for extracting a video transport stream packet including the first video stream, an non-video transport stream packet and timing information from a first transport stream;
- means for storing the timing information;
- means for generating the second video stream based on the first video stream;
- and
- means for multiplexing a video transport stream packet including the second video stream and the non-video transport stream packet based on the stored timing information to generate a second transport stream.
A method of transcoding a first video stream into a second video stream, comprising:
- extracting a video transport stream packet, including the first video stream, a non-video transport stream packet, and timing information, from a first transport stream;
- storing the timing information in a memory;
- generating the second video stream based on the first video stream;
- and
- multiplexing a video transport stream packet, including the second video stream and the non-video transport stream packet based on the stored timing information to generate a second transport stream.
