TimeCode Source
None
Timecodes are used to mark video frames,
mainly for editing purposes. This field either
disables timecoding, or selects the source to
“timecode” the encoded video frame. The
following selections are available:
●
None: No time code will be inserted in the
video stream (saves bandwidth if not
required).
●
Video (SDI only): The timecode will be
extracted from the incoming video signal.
●
System: If no timecode is included in the
video feed, the encoded timecode is
based on the encoder’s system clock.
In this case, it is a good idea to enable
NTP (see
“Configuring Network Settings”

Entropy Coding
CAVLC
(H.264 only) Select the compression
scheme:
●
CAVLC: Context-adaptive Variable-length
Coding is a lower-complexity alternative to
CABAC. CAVLC produces lower quality,
but is easier to decode.
●
CABAC: Context-adaptive Binary
Arithmetic Coding is an algorithm to
losslessly compress syntax elements in
the video stream. CABAC compresses
data more efficiently than CAVLC and
should produce better quality, but requires
considerably more processing to decode.
NOTE:
The H.264 decoder must be Main
Profile compliant or higher to decode a
CABAC video stream.
TIP:
CABAC provides better visual quality
because it is more efficient.
