AUDIO PROCESSING CHAIN
The audio processing chain is composed of the following elements:
n
One audio input front-end including one analog two digital embedded audio sources and oe
audio multiplexer
n
One sample rate converter
n
Three encoders
n
One set of audio outputs
Audio inputs front-end
The audio multiplexer selects a digital audio stream from one of the following three audio
sources:
n
Analog audio source
n
SDI audio source
n
HDMI audio source
The analog audio interface digitizes the analog audio stereo signal at 48 kHz.
The HDMI and SDI interfaces extract up to two audio channels of the embedded audio/video
signal. The sampling rate for such audio signal is determined by the HDMI/HD-SDI source.
Sampling rate converter
The sample rate converter adapts the sample rate of the audio stream to the desired rate.
Note: The sample rate is defined once for all the encoded audio streams and the audio
outputs. If e.g. we want to use G.711 encoder (8kHz), simultaneous output as linear PCM or
AAC is only possible at 8kHz!
