2.2.11 I Frame Detect
Enabling I Frame Detect will instruct the GV1000 to monitor the video being encoded for
high motion segments. If the GV1000 detects a large content change from frame to
frame an I frame will be produced regardless of the GOP value selected. This improves
the video quality during high motion segments when larger GOP values are selected.
2.2.12 Frame Drop
When the encoding bit rates exceed the set limit, the frame(s) producing the excess will
be dropped. Frame Drop should be used when transmitting over data paths that cannot
support bursty behavior (such as wireless transmission).
2.2.13 IMB in P (Intra Macro-Block in P-Frame)
Enabling IMB in P will improve video quality in the areas surrounding large amounts of
motion. Doing so will also reduce overall bit rates as less information is required to be
sent. This allows the use of larger GOP settings (I frame spacing) while retaining the
video quality.
2.2.14 Audio Encode
Future releases of the GV1000 may allow for audio encoding using codecs such as CELP
or G726.
2.2.15 Gain
Future releases supporting audio will allow for Gain, which will effectively act as a
volume control for the audio encoder.
2.2.16 Bit Rate
Audio bit rates will be configurable in future releases supporting audio. The bit rate seen
in Section 2.2.5 is the combined bit rates for audio and video combined.
