Description

This use-case allows the listener or an automatic processing system to choose between multiple languages.

Approaches

Multiple languages within an ADM file can be used in two different scenarios – to express two different intents. On the one hand, there is the non-interactive case, where the language is supposed to be selected before the playout. On the other hand, there is the interactive case, where the languages are supposed to be switched by the listener during the playback.

Non-interactive

To indicate that there should not be any user interaction multiple audioProgrammes should be used. In each audioProgramme the audioProgrammeLanguage attribute should be set accordingly. Each audioProgramme should reference all the audioContent elements which belong to it – the language specific and the language independent ones. Language specific audioContent elements should set the audioContentLanguage attribute. There should be only one language specific audioContent element for each language. There are no restrictions on the number of language independent audioContent elements.

Interactive

To indicate user interaction complementary audioObjects should be used. For each language there should be only one complementary audioObject, which should only be used to group all language specific audioObjects. Also, it should be referenced by its own audioContent element to signal language, loudness, etc. The audioProgramme should not have an audioProgrammeLanguage attribute. There is no restriction on the number of language independent audioContent elements.
