Hi!

The broadcaster triggers it. We (TsWriter) can detect the updates by looking for changes in the version field of the PMT:
MediaPortal/MediaPortal-1

No.

Yes, you won't find anything in the ETSI/DVB spec. This is an MPEG 2 transport stream (ISO/IEC 13818 part 1) concept. Refer to "Table 2-33 – Transport Stream program map section" (page 54) "version_number" field.

[code]version_number–This 5-bit field is the version number of the TS_program_map_section. The version number shall be incremented by 1 modulo 32 when a change in the information carried within the section occurs. Version number refers to the definition of a single program, and therefore to a single section. When the current_next_indicator is set to '1', then the version_number shall be that of the currently applicable TS_program_map_section. When the current_next_indicator is set to '0', then the version_number shall be that of the next applicable TS_program_map_section. [/code]
