4.9 Audio Menu
4.9.1 Overview
The Encoder can process two stereo pairs as standard, but with the
addition of Audio Option Cards it can process more. The control menu for
each stereo pair is essentially the same, but the options available are
dependent on the audio coding standard selected. See Figure 4.13 for the
menu structure.
4.9.2 Audio A / B Menus – MPEG Layer 2
Introduction
Audio A and B have the same menu options, depending upon the Coding
Standard selected.
Audio A Menus
are shown as examples. This menu
permits the selection of individual channel audio parameters.
Source Option
This option defines the audio source.
Table 4.38: Source Options
Selected Option Description
Off No audio packets are sent in the transport stream and audio is removed from the SI.
Mute Audio silence.
Test Tone An internally generated test tone is used as the audio source. The bit-rate automatically changes to 96 kbit/s.
Analogue Analogue audio input on AUDIO IN connector.
Digital Digital audio input on AUDIO IN connector.

SDI Embedded 4 Digital audio de-embedded from digital video input using DID 0x1FD.
Coding Standard Option
This option controls the audio coding standard. The options available in the
audio menu are dependent on the coding standard selected.
