Configuring an Encoder with SDI Input and IP or ASI Output
Defining the Logical Inputs
The first step is to define the service in Logical Inputs. For SDI input you must create the stream
objects to match your input content.
1. Begin by displaying SAG in your browser. (See Displaying SAG for instructions.)
The platform displays a SAG page similar to Figure 2–1 .
2. In the Configuration page > Logical Inputs panel, right-click Baseband SDI–1 and choose Add
New. Add a Baseband Video, and a Baseband Embedded Audio.
Figure 3–2: Adding streams to Logical Inputs
When you add the audio you indicate the group and pair that carry the audio.
If you plan to have
a stereo audio stream (or an audio passthrough stream), L/R will be taken into account. The
device will discard C/LFE and Ls/Rs.
For a real service, you would add all streams that correspond to the input content. You can then
choose to include them in the output when you create the output transport stream.
Any stream that you want to include in the output must be added here in the Logical Inputs first.
For example, if you want to output another video or audio from the same source input, you create
them here under Baseband SDI–1.
