4.2 Bitstream decoding and monitoring
Using the DP580 to decode and monitor incoming bitstreams begins with the selection of the
input signal type. The type of bitstream coming from a source determines the available
configuration and output options. In most scenarios, the DP580 monitors the output of an
encoded bitstream to ensure that the intended codec or contribution format is correctly output
throughout the broadcast stream.
4.2.1 Decoding and monitoring AES input
Selecting the AES option as the input on the DP580 enables decoding and monitoring of PCM,
Dolby AC-4, Dolby Digital Plus, Dolby Digital Plus with Dolby Atmos content, Dolby Digital, and
Dolby E bitstreams. The DP580 functions as a monitoring decoder to ensure the integrity of an
encoded bitstream.
About this task
The steps included here represent the workflow for a general example of an input. There may be
cases in which the outcomes are similar but different in their details.
Procedure
1. On the DP580 web client UI, select the Input tab.
2. From the Input drop-down list, select AES.
A single AES input can transmit only two PCM channels or one Dolby Digital Plus bitstream.
The channel pair details are displayed in the bottom-left panel below the drop-down list.
3. Double-click an input name to see the stream type that the combined input pair is receiving
(for example, 1.0 or 5.1 Complete Main).
4. View details about all characteristics of the channel pair by monitoring the panels on the
right-most side of the page.
The panels provide information about:
•
The bitstream on the channel pair (including the codec), the presence of Dolby Atmos
content, the dialogue normalization setting, and other similar data
•
Downmixing information, including the preferred downmix setting and accompanying
downmix level settings
•
General information, including the stream type, bitstream mode, and similar data when
present
•
Mixing metadata information, including whether it exists, the program and external
program scale factors, and the mix control, as well as related settings
4.2.2 Decoding and monitoring IP input
Decode and monitor the channels and presentations associated with the IP input. The DP580
functions as a monitoring decoder when used to ensure the integrity of an encoded bitstream.
Procedure
1. On the DP580 web client UI, under Setup, select the IP Bookmarks tab.
2. In the Bookmarks panel, check whether the IP source input you want to monitor is available.
3. Optional: If the IP source input you prefer does not appear in the list, add a bookmark In the
Add Bookmark panel for a new IP input source:
