elementary streams are required. This bypasses the Service Guide and other Service
Information (SI) tables.

NOTE…
1.
Selecting the video component by PID will result in the following actions. If the video PID
is identified in the PMT of the currently selected service, the video standard type is
automatically determined and used for decoding the video component. If the video PID is
not identified as being part of the currently selected service, the video standard type will
default to the user-defined video standard type. The user-defined video standard type
can be set using the COD sub-command described under the Video Command section.
2.
Selecting the audio component by PID will result in the following actions. If the audio PID
is identified in the PMT of the currently selected service, the audio standard type is
automatically determined and used for decoding the audio component. If the audio PID is
not identified as being part of the currently selected service, the audio standard type will
default to the user-defined audio standard type. The user-defined audio standard type
can be set using the COD sub-command described under the Audio Command section,
one for each audio route.
