z Image Format
H.264 and MJPEG are available for image format selection. The term, “image
format”, is referring to compression / encoding technique. The selection of image
format decides the performance of bandwidth and storage requirement. In the
request of same video quality, H.264 contributes to less bandwidth and storage
requirement, which is more efficient than MJPEG.
z GOP
In H.264 video coding, GOP (group of pictures) describes how the different types of
frames are arranged. The frame types implemented here are I-frame (full image
information) and P-frame (motion-compensated difference information). This setting
configures the GOP length which is the number of frames before next I-frame appears.
Having more I-frames usually increases the stream size, and therefore more
bandwidth and storage are required.
z Frame Rates
The Frame Rates defines the number of frames that will be displayed per second.
The frame rate setting can affect the target bit rate (bandwidth requirement) and
storage requirement.
Note:
While multiple streaming is possible, each stream has its limitation and dependency to
other stream.
