3.7.3 Selecting the Audio Component Introduction
Automatic audio component selection is based on component order in the
PMT as follows:
• Audio 1 selects the first component in the PMT and Audio 2 selects the
second component.
• Audio 1 does not select the same component as Audio 2 and vice-versa
when component-PIDs are reordered in a new PMT.
• Coding type and language are manually selectable through the
User PID and type parameters.
Selecting the Audio Manually
It is possible to manually select any audio component from the active
Service by using the front panel controls or via the remote control
interface. Select one of the audio components in the list or enter the
correct PID. Table 3.13 describes the procedure for selecting a component.
