1RU Multi-Path Video Converter, Frame Synchronizer and Decoder
The controls for the audio processor are segmented into seven logical categories as shown below.
The following sections will outline in detail the parameters under each of these seven categories.

Configuring the Embedded Audio Per Channels Delays
The HD201x de-embeds 4 groups (16 channels) of audio from the video supplied to each of the
HD201x video processing paths. The HD201x supports per channel delay for de-embeddeded audio
channels. For the sake of brevity, the audio delay control for de-embedder 1, channel 1 only. Delay
controls for all other de-embedders and channels operate in the same way.
NOTE:
Deembedder 1 corresponds to the audio de-embedded from PATH1
Deembedder 2 corresponds to the audio de-embedded from PATH2,
Deembedder 3 corresponds to the audio de-embedded from PATH3
Deembedder 4 corresponds to the audio de-embedded from PATH4.

5.2.1.2.
Configuring the Embedded Audio Sample Rate Converters
The HD201x de-embeds 4 groups (16 channels) of audio from each of the video supplied to the input of
each processing path. The HD201x supports control over the relevant sample rate converters on a per
channel pair basis.
For the sake of brevity, the audio sample rate converter control for de-embedder 1, channel pair 1 will
only be discussed in this manual. Sample rate converters for all other de-embedders and channels
pairs operate in the same way. It is recommended that all audio sample rate converters remain in auto
mode.

Table 5-3: Top Level of the Audio Setup Menu
Units of measure are audio samples (48 KHz sampling).
Select a value from 0 to 16383 audio samples.
Each audio sample is 48 KHz and therefore represents a delay of
0.02 ms. Therefore, 0 samples correspond to 0ms of delay and 16383
corresponds to ~ 314 ms of delay.
