For example, transmitter one may have a wide shot of the target house requiring only

low bit rate so you can see the door open or the car arrive.

Transmitter two might have a high resolution camera on a close up of the door so you

can identify the target. This will require high bit rate.

Let’s see how we might do this:

3. Chain your transmitters together.

4. Move the Bit Rate Balance slider to suit your operation.

In my example I have chained encoder two into encoder one so I can transmit two video

products over the single frequency of RF Output 1 (1000MHz).

Then, I moved the Bit Rate Balance slider to allocate 75% of the available bit rate to

Encoder two and 25% to Encoder one.

13.15 Dividing Bit Rate using a Manual Method

You can see the great advantage of being able to divide the Bit Rate unequally using the

SOLO 6 Bit Rate Balance Slider, but what if you don’t have SOLO 6?

There is a manual way of doing this same exercise using two conventional transmitters.

Before you Begin

You’ll need:

 At least one Receiver.

 Two SOLH264TX Transmitters each configured to accept an SD video source.

 A video source for each transmitter (I’m using SD in my example)
