Figure 3-4 Program Config menu
Selecting a Program Config assigns all metadata values that best fit the most common
use of that configuration. Although the metadata values can be modified, it is unlikely
the user will need to do so. See Section 3.2.4 - Metadata Params for a discussion of the
values that may need to be changed.
Notational Conventions
The + symbol separates programs within a configuration. For example, 5.1 + 2 represents
one 5.1-channel and one stereo program. The x symbol shows the number of a given
channel format within that configuration. For example, 4 x 2 represents four two-channel
programs. One configuration has three different formats: 4 + 2 + 2 x 1 is one four-channel,
one two-channel, and two mono programs.
Encoding Considerations
It is important to distinguish between configurations with the same number of channels
but different program formats, such as 8 x 1 and 4 x 2. Although both configurations
encode eight channels, 8 x 1 uses eight metadata streams while 4 x 2 uses two. Increasing
the number of programs with independent metadata streams decreases the number of
encode/decode generations possible without audible degradation.
