The example below shows how to deliver a new 7.1 surround audio data file for a film previously delivered.
The following summarizes the effects of updating existing content:
Existing film with 2.0, 7.1 surround audio, and 5.1 surround audio: If you send a new update with only 2.0 audio, only the 2.0 audio file is replaced, keeping the original 7.1 surround audio and 5.1 surround audio.
Existing film with 2.0, 7.1 surround audio, and downmixed 5.1: If you send 2.0 and 5.1 surround audio, only the 2.0 and 5.1 surround audio files are replaced, keeping the original 7.1 surround audio. The existing downmixed 5.1 surround audio will be replaced by the provided 5.1 surround audio.
Existing film with 2.0 and 5.1 surround audio: If you send 2.0 and 7.1 surround audio with "audio.surround.force_5_1_downmix" attribute set to true, you must remove the existing 5.1 audio before or at the same time as sending "audio.surround.force_5_1_downmix" set to true. See Overview of Asset Removal for information on removing an asset.
Existing film with 2.0 and 5.1 surround audio: If you send 2.0 and 7.1 surround audio with "audio.surround.force_5_1_downmix" attribute set to false or omit the tag, the original 5.1 surround audio file is kept as is.
