may also use the Client Setting to disable the audio transmission.

Client Settings

Users can configure the following functions in Client Settings.

1. Encoder standard: Shows the encoding algorithm currently being used. VPort 364A features built-in 2

encode engines to generate dual simultaneous video streams. Each client can select the H.264 video

streams from Stream 1, or the MJPEG video stream from Stream 2. To configure these video streams,

please go to System Configuration Video Video Performance.

2. Media Options: Enable or disable the video or audio transmission.

3. Protocol Options: Choose one of four protocols to optimize your usage—Multicast (RTSP or Push) or Unicast

(UDP, TCP, HTTP).

• Multicast protocol can be used to send a single video stream to multiple clients. In this case, a lot of

bandwidth can be saved since only one video stream is transmitted over the network. However, the

network gateway (e.g., a switch) must support the multicast protocol (e.g., IGMP snooping). Otherwise,

the multicast video transmission will not be successful.

 RTSP: Enable the multicast video stream to be sent in RTSP control, which means the multicast video

stream will be sent only it receives the client’s request.

 Push: Enable the multicast video stream to be sent in Push control, which means that after this

setting is selected the multicast video stream will be sent continuously even without any client

request.

• Unicast protocol is used to send a single video stream to one client.

 UDP can be used to produce audio and video streams that are more real-time. However, some

packets may be lost due to network burst traffic, and images may become blurred

 TCP can be used to prevent packet loss, which results in a more accurate video display. The downside

of using TCP is that the real-time delay is worse than with UDP protocol.

 HTTP can be used to prevent being blocked by a router’s firewall. The downside of using HTTP is that

the real-time delay is worse than with UDP protocol.

Once the video encoder is connected successfully, Protocol Options will indicate the selected protocol. The

selected protocol will be stored on the user’s PC, and will be used for the next connection.
