Table 2-6. Input Video, Embedded Audio, and Compressed Audio Processing with External
Audio Compression and Decompression
Description Products
HD-SDI video with embedded audio and embedded compressed audio is
processed using the X75HD and external audio decompressor and compressor.
The HDTV video and AES program signals are processed through the X75HD.
Embedded compressed audio is sent to an audio decompressor, providing three
AES (5.1) signals to the X75HD. The X75HD processes the audio signals and
then sends them to an audio compressor. The compressed audio signal is sent to
the X75HD where it is embedded into the output processed program video signal.
