Description
VBR maximum
bit rate
Range: [0...15000]. Sets a limit for variable bit rate.
Q min I
Used to achieve consistent picture quality within a single GOP or across
consecutive GOPs. Lower values produce a better picture, but will yield
higher bit rates and require more processing. Default Q min I = 3; default
Q min P = 2.
Q min P
Frame rate
divider
Relates to the frame rate configured in the Encoder Settings section.
X-resolution
Variables that enable you to freely set picture resolution instead of using
the resolution presets in the Encoder Settings section.
Y-resolution
Request I-
frame
When joining a multicast stream in the middle of a long GOP, requesting
an I-frame will speed up response time, i.e. image display will start
sooner.
Request I-
frame hold off
Range: [0…255] frames. Requesting (too) many I-frames may add to
latency. To prevent this, you can specify the distance in frames, starting
after the previous I-frame, before another I-frame is sent upon request.
Meta data
insertion mode
For details, see the section on Meta Data Insertion.
Disabled
No meta data added to stream.
Fixed interval
Not supported for MPEG-4 streams. If
a fixed interval is set, the nearest I-
frame will be used.
Each I-frame
Data block is added after each I-frame.
The interval is determined by the GOP
length, therefore.
Meta data
insertion
interval
Activate this parameter by setting Meta data insertion mode (above) to
Fixed interval.

Stream Manager, Transmitter #, RTSP Transmitter, and SAP settings
Configuring Stream Manager, Transmitter #, RTSP Transmitter, and SAP settings for
MPEG-2/4 encoding is done in the same way as for Encoders 1/2. For details, see the
description earlier in this chapter.
