Configure encoding
For example:
l
if the input signal resolution is 1920×1080 (a 16:9 aspect ratio)
l
and stream frame size is set to another 16:9 frame size such as 1280×720,
the smaller stream frame size causes the system to downscale the image and use less bandwidth to
transmit.
Or if you have a widescreen/HD format source but need a 4:3 output frame size, you can add black bars to
the top and bottom of the frame.
The system is designed to provide scaling, however for the best overall system performance
(particualrly when reaching maximum system capacity), configure your source to provide the
correct frame size and avoid scaling.
To configure your stream's frame size:
1. Connect to the admin interface using your preferred connection mechanism. See
2. Login as admin.
3. Click
Encoding
for the your channel; the encoding configuration page opens.
4. Scroll to the
Frame size
section.
5. Perform one of the following steps:
Using current signal resolution as the frame size only works for channel layouts with a
single source. If you're using multiple sources, follow the steps below to set your frame
size.
a. Check the
Use current signal resolution as the frame size
check box. Enabling this feature
greys out the other frame-size configuration fields. The system automatically streams at the
frame size of the input signal.
