Restrictions on the Number of
Distributions for Camera
The maximum number of distributions for camera is determined by the settings as well as requirements from the client.
For JPEG distribution, you can select either
AFrame Rate PriorityB mode or AClient Number PriorityB mode. AFrame Rate PriorityB mode distributes JPEG images according to the frame rate requested by the client. The maximum number of distributions is determined based on the highest bit rate within the distribution streams. For AClient Number PriorityB mode, if there are requests from multiple clients, JPEG images are distributed in a lower frame rate than that requested to cater to multiple clients. It can accept 20 distribution requests as the maximum number of clients.
When Frame Rate Priority Mode is Selected
JPEG images are distributed as the frame rate requested by the client.
When a distribution request that exceeds the maximum number of distributions is received, this request is denied.
●When only JPEG images are distributed For example, if Client A requests for JPEG at 1 Mbps, while Client B requests for JPEG at
5 Mbps, additional 2 stream (total 4 streams) of distribution are possible for request below 5 Mbps.

●When both JPEG and H.264 data is distributed When both JPEG and H.264 images are distributed simultaneously, up to two clients for JPEG and three clients for H.264 can be distributed, respectively. However, distribution requests that exceeds a total bit rate of 20 Mbps will be denied.

●When distributing only H.264 data
The maximum number of distributions is determined by the preset bit rate. When a distribution request that exceeds the maximum number of distributions is received, this request is denied.

When Client Number Priority Mode is Selected
●When only JPEG images are distributed
If the distribution request would be accepted in the frame rate priority mode, distribution works in the same way as frame rate priority mode, where JPEG images are distributed at the frame rate requested by the client. If the distribution request would be denied in the frame rate priority mode, the frame rate is controlled such that the maximum bit rate is as shown in the following table, to accept distribution requests from up to 20 clients. For example, if Clients A and B request for JPEG at 10 Mbps, the frame rate will be reduced such that the distribution bit rate to each client is less than 5 Mbps.

●When both JPEG and H.264 data is distributed When both JPEG and H.264 images are distributed, distribution works in the same way as frame rate priority mode if the distribution request would be accepted in the frame rate priority mode. If the distribution request would be denied in the frame rate priority mode, the frame rate is controlled such that the maximum bit rate is as shown in the left table (Maximum number of distributions when JPEG and H.264 data is distributed), to accept distribution requests for up to 20 a total number of 20 JPEG and H.264 distributions. However, distribution requests for which the total bit rate of the H.264 distribution stream exceeds 10 Mbps will be denied.
