Time to Live (TTL): Set the effective scope of multicast distribution for RTP video streaming between 1 and 255. TTL is a
mechanism that limits the lifespan of data in a computer or network. It is implemented by having a counter or timestamp
attached or embedded in the data in order to ensure that data is discarded once the correct time is reached. TTL counter
decrements each time the signal pass through a router, so when the value reaches 0, the signal can no longer be
distributed. For example, if TTL is set to [1], multicast distribution is confined to the local segment only and cannot be
distributed by the router.
Always Multicast this stream: Check this box to start on-demand multicast RTP video stream without opening a new
RTSP session.
Secondary Video Stream
Repeat Primary Video Stream setting steps for the Secondary Stream settings.
Tertiary Video Stream
Repeat Primary Video Stream setting steps for the Tertiary Stream settings.
Audio Stream
Repeat Primary/Secondary Video Stream setting steps for the Audio Stream settings. However, notice that settings here are
related to Audio, not video. NOTE: Audio stream configuration is synchronized to each video stream.
Restore Default Multicast Settings: Click this button to restore to the camera’s default multicast settings.
Revert to previous Multicast Settings: Click this button to revert to the camera’s previous multicast settings.
TCP/IP
Max. Transfer Unit (MTU): Set the value in the range 576 to 1500 for the largest packet size that can be sent through RTP
streaming.
Restore Default TCP/IP Settings: Click this button to restore to the camera’s default TCP/IP settings.
Revert to previous TCP/IP Settings: Click this button to revert to the camera’s previous TCP/IP settings.
2.2.4.5 Pelco Smart Compression
The Pelco Smart Compression features the brilliantly efficient stream compression technology to not only economically exert
leverage between different regions and compression levels, but also effectively reduce the average bit rate to level down the
overall bandwidth exploitation. Refer to the following section for elaborate descriptions.
