MPEG4 reduced frame rates be employed when the unit is operating at

low bitrates (1.25MHz bandwidth FEC1/3).

Video Bitrate

This control can be used to set the video bitrate within the constraints of

capacity available in the channel, but only when “Chaining Input” is set

to ON.

For normal SOLO transmitters, chaining CANNOT be enabled, and as

such video bit rate control is automatic.

The video bit rate is automaticall

y maximised in each configuration

when “Chaining Input” is turned off.

Horizontal resolution

The video coding resolution can be selected from 704, 528, 480 and

352 pixels. Changing the horizontal resolution to lower values will make

the coded picture softer.

Care should be taken to match the horizontal resolution to the resolution

of the camera connected to the transmitter; this will give best image

results.

Audio Encoder

The Audio can be turned on and off with this control. Audio is OFF by

default, but there are several audio modes that vary from very high

quality to speech grade that can be selected with this control. Enabling

audio will degrade the video quality, because some of the available data

capacity is diverted away from video to audio. Selecting high fidelity

audio modes will degrade the video quality more than lower fidelit

audio modes. The Audio encoder can also be switched to 32 kHz and

48 kHz MPEG Layer 1 modes; from software V3.3 upwards.

Note: The Solo4 receiver only supports 48 kHz sampling in MPEG Audio mode

and bit-rates in the range 192 to 448kbits/s.

Audio Input Level

This control is used to define the audio gain to be applied to the audio

input signal. 0dB is used for line level audio and various options up to

48dB of gain can be applied for microphone inputs.

Unit Name

This field allows the user to enter an identifier for the service that they

wish to transmit. This must match that selected at the receiver for the

service to be decoded. The unit name can be constructed of

any eight

ASCII characters.
