Video If this is disabled no video can be seen using RTSP.
Audio If this is disabled no audio can be heard using RTSP.
Closed Caption If this is disabled no closed captioning can be seen can be heard using
RTSP.
Closed Caption
AUs Per RTP
Packet
This is the number of frames of closed caption frames (access units)
that are placed in each RTP packet. Since each closed caption frame is
small, if multiple Aus are placed in a single RTP packet the bandwidth
efficiency is improved at the cost of additional latency.
Total Bit Rate This is the maximum amount of data the VBrick will generate at any
time using RTSP. It's the total calculated by adding together the data
in all the video/audio/cc streams (including network overhead) that
have been started using RTSP. When this maximum is reached, no
additional MPEG-4 players will be allowed to use the RTSP method.
Resource Name The name used in an RTSP URL to locate a particular stream.
Announce RTSP
Server
This section is used to announce the RTSP streams to the local
network allowing viewable RTSP SAPs in programs like StreamPlayer
Plus. The unit must be on the same segment of the network or the
Router must be configured to retransmit broadcast in order for the
SAPs to be accessible using the IP Address 255.255.255.255.
Announce
External RTSP
Server
This section is used to announce RTSP streams to a Network device
outside of the broadcast domain.
