Abstract
A system and method for processing SI data such as PSIP/PSI data in a digital TV environment are discussed. In the method for processing SI data from a plurality of input transport streams into at least one output transport stream for a digital broadcasting, SI data from the input transport streams are extracted and decoded, the decoded SI data are mapped by being reconfigured for the output transport stream, and the mapped SI data are merged and re-encoded to generate the output transport stream.
Claims34
A method for processing service information (SI) data from a plurality of input transport streams into at least one output transport stream for a digital broadcasting, the method comprising:
- extracting SI data from the input transport streams;
- decoding the extracted SI data;
- and
- mapping the decoded SI data by reconfiguring the SI data for the output transport stream.
A system for processing service information (SI) data from a plurality of input transport streams into at least one output transport stream for a digital broadcasting, the system comprising:
- a receiver section to receive the plurality of input transport streams;
- an extraction section to extract SI data from the input transport streams;
- and
- a metadata processing subsystem to decode the extracted SI data and to map the decoded SI data by reconfiguring the SI data for the output transport stream.
A computer program product embodied on at least one computer-readable medium, for processing service information (SI) data from a plurality of input transport streams into at least one output transport stream for a digital broadcasting, the computer program product comprising computer-executable instructions for:
- extracting Si data from the input transport streams;
- decoding the extracted SI data;
- and
- mapping the decoded SI data by reconfiguring the Si data for the output transport stream.
