Example 3

The HLS output group consists of:

  • One video high output.

  • One video low output.

  • Two audio outputs (English, French) that each use the AAC codec. These outputs both belong to the same audio rendition group, RG1.

  • Two audio outputs (English, French) that each use the Dolby Digital codec. These outputs both belong to the same audio rendition group, RG2.

  • The video high output is associated with both audio rendition groups.

  • The video low output is associated only with the RG1 audio rendition group.
