11 DIGITAL PROCESSING MODULES
11.1 AUDIO LEVELING MODULE
The Audio Leveling card is able to adjust the audio level for up to 250 audio PIDs. The leveling process operates
purely in the digital domain which means there is no signal degradation associated with this process.
The concept with the Audio Leveling card is to be able to adjust all the outputs to the same audio level so that
zapping between channels will be more comfortable.
Figure 11.1 - Audio Leveling Effect
The audio leveling card is intended to be used with all available outputs.
The audio leveling parameters are configured as part of the service output setup.
Figure 11.2 – Setting up Audio Leveling
The following parameters are available:
Processor
Select the audio leveling card to route the input stream through – the unit
supports multiple cards per chassis.
Check box
Enable the audio leveling algorithm
Slider/Dropdown box
Adjustment level – the range is +/- 30dB, in steps of 2dB
11.2 ELECTRONIC PROGRAM GUIDE (EPG)
The Electronic Program Guide (EPG) module is responsible for collecting event information from all incoming
transport streams, usually via PID 18, and regenerating this information for EPG-enabled outgoing networks.
