Initial Streaming and Current Streaming States
These two parameters control the static (non-volatile) streaming state of the encoder, both actual and
after boot-up.
• The Current Streaming State controls whether the encoder is actually encoding and sending
video over the network. The stream controlled by this parameter is always non-volatile.
(Volatile streams cannot be seen or controlled in the CLI.) The Current Streaming State
parameter is never saved in the configuration, so set the Initial Streaming State parameter if
a constant setting is desired.
• The Initial Streaming State setting determines the value of the Current Streaming State after
boot-up. If this is enabled, the Current Streaming State will be enabled as well, and the unit
will start streaming immediately.
Transport Protocol
This parameter specifies both the Internet protocol that will be used to transmit the video stream over
the network and the video protocol that will be used to decode the stream.
• For the Internet protocol, you have a choice between TCP and UDP — two well-known and
widely used protocols.
• For the video protocol, you have a choice between VSIP, a proprietary video and audio
protocol, and RTP, an accepted industry standard.
It is suggested that you set this parameter to RTP/UDP. Use TCP only in setups where UDP is not
accepted or if you have occasional packet loss.
Energy Vector (EV) Transmission Rate
The energy vector represents a measurement of movement in the image. Its value can range from 0
(no movement) to 255 (a lot of movement). The Energy Vector (EV) Transmission Rate is the
frequency, in frames, at which the energy vector is computed and sent over the RTP/UDP stream. A
value of -1 means there is no video signal going to the encoder. This setting is used by video
management software only.
Web Multicast IP Address and Port
These are the Multicast IP address and port that will be used only if the Multicast streaming method is
chosen for live viewing on a Web page. To stream Multicast to one or multiple receivers, you must set
the target IP address to a valid Multicast group.
Target VSIP GUID
Useful for TCP streaming, this is very hard to set manually. It is used by SConfigurator or other
software to create non-volatile video TCP connections.
