Getting Started
8. Click on the Encode tab.
9. Set the Coding Standard to MPEG Layer II.
10. Set the Coding Mode to either 6 Channel Aligned or 8 Channel Aligned.
The unit will automatically set the other input sources and the necessary languages
and dual phase aligned audio output can now be produced.
3.16 How to Set Up Input for 3/2L (5.1 Surround) Encoding
Overview
The unit can only de-embed stereo channel pairs (groups) from the SDI/HD-SDI
input signal. Therefore, to set up 5.1 encoding, three groups have to be de-
embedded from the SDI/HD-SDI input signal, and routed to the audio encoder.
The embedded groups have to be consecutive. That is, they have to carry the
different channels as detailed in Table 3.12 (SMPTE 320M).
Table 3.12 Embedded Stereo Channel Pairs
Group Description
Embedded n Left Front, Right Front
Embedded n+1 Center, LFE
Embedded n+2 Left Rear, Right Rear
Configuration
Note: This procedure assumes that a service has already been created. If not, one
must be created before continuing.
1. In the Inputs widget, select Audio Stream 1.
2. Drag the selected component to a service in the Outputs widget.
3. In the Outputs widget, click on the audio component.
Note: If you click on the Audio component in the Outputs widget, the
corresponding audio stream will be highlighted in grey in the Inputs widget.
4. In the Properties widget, click on the Input tab.
5. Set the Input Format to Uncompressed (LPCM)
6. Set the Input Source to Embedded n (SDI 1), the embedded stream that
contains the left front and right front channels.
7. In the Properties widget, click on the Encode tab.
8. Select the required Coding Standard.
9. Select 3/2L (5.1 Surround) for Coding Mode.
