6. Video

The following descriptions show examples of some of the features available with V960D.

6.1 Video Codec

This section allows you to choose the compression codec for each of the video streams.

Motion JPEG

This format uses standard JPEG still images in the video stream. These images are then displayed

and updated at a rate sufficient to create a stream that shows constantly updated motion.

The Motion JPEG stream uses a considerable amount of bandwidth, but also provides excellent

image quality and access to every individual image contained in the stream.

Multiple clients accessing Motion JPEG streams could use different image settings.

H.264

This is a video compression standard that makes good use of bandwidth and could provide

high-quality video streams at less than 1 Mbit/s.

The H.264 standard provides the scope for a large range of different coding tools for use by

various applications in different situations, and the

V960D 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.
