3.14.4.2.4 Audio Decoder > Mode
The Mode field is a read-only field that reports the current mode of the Audio
Decoder. This state depends on the Mode configured in the Decode > Advanced
settings and also depends on the audio format type. If pass-thru is not supported for
the audio format in use then the Audio Decoder will attempt to decode the audio
stream by default.
• DECODE – The Audio Decoder is decoding the audio stream. The default state
if pass-thru of the audio format is not supported.
• PASS THRU – The Audio Decoder will pass-thru the audio stream without any
alteration. Typically, the audio stream is passed on to an external piece of
equipment that will decode the audio stream.
3.14.4.2.5 Audio Decoder > Language
The Language fields are read-only fields that report the audio language of the audio
stream being decoded (or pass-thru). In the case where the audio stream is stereo
or mono, only the Language 1 field may be specified. In the case where the audio
stream is dual mono, both the Language 1 field and the Language 2 field may be
specified.
