1) Compressed Data
The audio data inputted to ZIC1 (Vaddis 882) A/V decoder is divided into compressed data and uncompressed
data.
It is compressed data that is compressed with multi-channel audio data such as Dolby digital, MPEG, DTS,
WMA,etc. The compressed data inputted to ZIC1 (Vaddis 882) is converted into the uncompressed data of 2, 4,
and 6 channels through ZIC1 built-in audio decoder and is outputted to Data 0 through digital audio interface.
The compressed data is transmitted to external AC-3 amplifier or MPEG/DTS amplifier as IEC-958/1937 trans
mission data format compressed by ZIC1 built-in IEC-958 output process.
2) Uncompressed Data
The uncompressed data is that data isn't compressed, so it is called CD-DA, LPCM data.
The 2 channels data is converted through audio decoder 2-channel data and Data 0 and are outputted in digital
audio interface.Via IEC-958 output process, they is transmitted to digital amplifier or AC-3/MPEG/DTS
amplifier built in the external digital input source with IEC-958/1937 transmission format.
