5. Camera and Image
The following descriptions show examples of some of the features available in the
NMDI.
5.1 Video Codec
These are the tools for adjusting the H.264 settings and controlling the video bit rate.
H.264
This is a video compression standard that makes good use of bandwidth and which
could provide high-quality video streams at less than 1 Mbit/s.
The H.264 standard provides scope for a large range of different coding tools for use
by various applications in different situations, and the NMDI provides certain subsets
of these tools.
Using H.264, it is also possible to control the bit rate, which in turn allows the amount
of bandwidth usage to be controlled. CBR (Constant Bit Rate) is used to achieve a
specific bit rate by varying the quality of the H.264 stream. While using VBR
(Variable Bit Rate), the quality of the video stream is kept as constant as possible, at
the cost of a varying bit rate.
