General contd.
- Hence a conventional Broadcaster of a TV channel or service having one program would be composed of a series of “broadcaster programmes” or events with the same program_number and a common PCR_PID.
- In other words the PCR time base effectively creates a virtual channel which may be associated with a single or multiple program_numbers.
- A TV channel having multiple programs would have multiple program_numbers with either single or multiple PCR_PID between program streams.
- NOTE : Services with different program_numbers may draw upon the same video as with the case of multilingual srevices.
