Using source groups with your channel's outputs
A source group associates a package configuration with an output on a channel. When you create the package configuration on the source, you identify the source group's name. Then, when you create the output on the channel, you enter that same name to associate the output with the package configuration. VOD sources and live sources that are added to a program on a channel must belong to the source group that's identified in the output.
For example:
-
VOD sources 1 and 2 both have three package configurations that have the source groups: HLS, DASH, and HLS-4k.
-
VOD source 3 has two package configurations with source groups HLS and DASH.
If channel A has two outputs with source groups HLS and DASH, the channel output can use all three VOD sources. That's because VOD sources 1, 2, and 3 all have package configurations with source group labels HLS and DASH.
If channel B has two outputs with source groups HLS and HLS-4k, it can use VOD source 1 and 2, but not 3. This is because VOD sources 1 and 2 both have package configurations with source group labels HLS and HLS-4k.
If channel C has a single output with the source group DASH, it can use all three VOD sources. All three VOD sources have package configurations with the DASH source group.
