D.7.6 Surround EX Mode
This parameter is used to identify the encoded audio as material encoded in Surround
EX
TM . This parameter is only used if the encoded audio has two surround channels. An
amplifier or receiver with Dolby Digital Surround EX decoding can use this parameter as
a flag to switch the decoding on or off automatically. The behavior is similar to that of the
Dolby Surround Mode parameter.
D.7.7 A/D Converter Type
This parameter allows audio that has passed through a particular A/D conversion stage to
be marked as such, so that a decoder may apply the complementary D/A process.
