Additionally, each FHD264-R comes with an IR Remote control that
works at a frequency of 56 KHz. The IR Remote can be used to quickly
change Receiver groups:

Use NAV keys to increment or decrement the group by one

Use NUM pad to go to any group in the range of 0 to 63

Keys A and B are reserved for future use

5.8 Video Scaling and Bit Rate Control
The FHD264-S (Sender) has internal video scaling capabilities. The user can control the bit
rate and scaling feature depending on the network bandwidth. The user can change the
settings in three ways – WebGUI, Telnet, or PC GUI. Please consider the following if you
decide to change settings from default:

The input of the sender is the source video fed into the sender.

The output of the sender is the network stream.

Reducing the bit rate will decrease the occupied bandwidth on the network.

By default, these settings are optimized for the best image possible without undue
burden on the network.
5.8.1 Scaler and Encoder Settings
If you are using a source with 1080p resolution, then use “Scale Full HD to :” option to either
transmit the video at the same resolution on the network, or to first downscale the video from
Full HD to HD (or SD) and then transmit the lower resolution image on the network. By doing
so you will force the unit to use the bit rate for HD instead of Full-HD, which is typically much
lower. This lowers the resolution for each Receiver from 1080p/60 to 720p/60. But, if the video
has a lot of motion and action, there will be less compression, resulting in a clearer overall
picture, while using less bandwidth.
However, if you have a Full HD (1080p) source video where the amount of motion on the
screen image is limited (such as a slide show), you can skip scaling it down and just reduce
the bit rate for Full HD. That way you are not sacrificing any resolution of the original image.
If you are using a 720p source resolution, the use “Scale HD to:” option to downscale the
video to Standard Definition (SD) to transmit in the network. Click “Update Scaler” to confirm
the settings.
Once the Scaling Settings are confirmed, select the Full HD, HD and SD bit rate in the
Encoder Settings section and click “Update Encoder”.
