Module mpeg2ts_reader::psi [−][src]
Types for processing tables of Program Specific Information in a transport stream.
Concepts
- There are multiple standard types of Program Specific Information, like the Program Association Table and Program Map Table. Standards derived from mpegts may define their own table types.
- A PSI Table can split into Sections
- A Section can be split across a small number of individual transport stream Packets
- The payload of a section may use section-syntax or compact-syntax, as indicated by the
section_syntax_indicator
attribute- Section-syntax sections have additional header data, represented by the
TableSyntaxHeader
type - Compact-syntax sections lack this extra header data
- Section-syntax sections have additional header data, represented by the
Core types
SectionPacketConsumer
converts Packets into Sections
Note that the specific types of table such as Program Association Table are defined elsewhere with only the generic functionality in this module.
