Web GUI Control

Un-checking this box allows you to set a specific group rate. If you know your

pass-through components are higher than the above allowance, you should

manually set a lower group rate.

Note: If this box is unchecked and you set a Group Bit Rate manually, take care to

ensure that there is enough headroom to accommodate all non-video

components in the transport stream.

 Group Bit Rate – When the above Use Max Available Bit Rate box is

unchecked, this field can be modified to set a specific group bit rate. When the

Use Max Available Bit Rate box is checked, this field is not modifiable and is

greyed-out, showing the bit rate that has been automatically set.

 Video Delay – Enables a specific video delay to be set. The range of delay that

can be set depends on the output video format used (HD, SD, MPEG-2, H264).

Allowing a longer delay will usually give better overall coding efficiency and thus

better picture quality for a given group bit rate. The minimum bit rate (Bmin) that

a video component will be allowed to drop to will depend on the delay setting

and the output video format, so as to not violate the MPEG buffer models. Bmin

will be calculated and set automatically.

This pane shows the Service accor

dion with the Service Properties tab selected.

The number of selectable accordions and the range of parameters within those
