Description Products
An HD-SDI signal with embedded compressed audio is processed using the
X75HD and an external audio decompressor.
The embedded compressed audio stream is de-embedded and provided as an
AES stream into the audio decompressor. The decompressed audio streams (four
AES, eight channels) are processed and timed with the video signal.
