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.
Ⅵ 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.
Maximum number of distributions when only
JPEG images are distributed
● 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.
Maximum number of distributions when
JPEG and H.264 data is distributed
● 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.
Maximum number of distributions when
H.264 data is only distributed
Ⅵ 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.
Maximum bit rate when only JPEG data is
distributed
● 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.
