5.5.4.1 Transport Stream Configuration
The Transport Streams generated by the unit are fully compliant with the MPEG-2
Transport Stream specification (ISO/IEC 13818-1), and consists of services that
carry one or more components.
The unit can form up to 18 output Transport Streams and output them through the
Transport Stream output interfaces.
A total of 256 services can be allocated between the output Transport Streams.
Each service can contain a maximum of 24 elementary streams. The elementary
streams that make up a service can be selected from the elementary streams
available from the option cards. The only restriction is that the elementary streams in
a service must all reference the same 27 MHz clock.
An elementary stream can be included in up to four services. Only one video
elementary stream can be assigned to a service, and the audio delay of audio
services should be matched to that video. Only one PCR can be associated with a
service.
Settings for IP and non-IP output Transport Streams differ slightly. The following
three sections define the general Transport Stream settings, the settings that are
related to the IP output, and the settings for the various services within the IP or
non-IP output Transport Streams.
5.5.4.1.1 General Transport Stream Settings
The general Transport Stream parameters are available in the Properties widget on
the Service Configuration page if a Transport Stream is selected in the Outputs
widget. The same settings are also available through the front panel under
Output/<interface name>/<Transport Stream name>.
