Configuring rtsp Server module

The rtsp Server object is used for transmitting video from Server to remote workplaces using the RTSP protocol. Use of the RTSP protocol allows viewing video from IP cameras and video archive on remote clients by means of the Intellect software or using video players that support this protocol. 

When MJPEG codec is in use, video of height and/or width more than 2048 pixels is not supported.

To create and configure the rtsp Server object, do the following:  

1. In the context menu of the Computer object select Create object => rtsp Server.
2. Specify the name and ID of the object in the opened panel.
   
3. Click the Apply button to create the object.
4. Open the settings panel for the rtsp Server object. For this select the created object in the Intellect objects tree.
   

5. In the Cameras table set the checkboxes next to video cameras video from which is to be displayed (1).

   Note.

    To select several cameras at the same time, mark lines in the table and then holding down the Ctrl key on the keyboard click the unchecked box in one of the marked lines.
   
   As a result all selected lines will be set checked.
   To uncheck several boxes at the same time, do the same, but click the checked box after the selection of the lines.
6. If video from the camera is to be received through the video gate, then select the Vide ogate object in the Gate drop-down list (2). 
7. In the RTSP port field specify the port via which the video is transmitted (3).
8. In the HTTP port field specify the port that is to be used for transmitting video via http-protocol (4).

9. To distribute transmitted signal among different rtsp-ports set the Multicast checkbox (1). In the Cameras table the Port column is displayed. Every video camera is to have a data transmission port (2).

   The following ports are in use for each camera in the Multicast mode: nPort, nPort + 18000 (rtp), nPort + 19000 (rtcp), where nPort – port number specified for camera in the Port column.
   

   Note.

   Use of the Multicast mode allows decreasing Server load due to reduction of transmitted data.

   Note.

   In spite of specifying video data port it is required to specify camera number in source address (see table below).

   Note.

   To get such video in the Intellect software (see Configuring multimedia receipt using RTSP protocol) set the multicast value to the rtsp parameter in the HKEY_LOCAL_MACHINE \SOFTWARE\ITV\Intellect\Video\TransportProtocols registry section on computer where the Camera object is created. Detailed information on this parameter see in   Changing the transport protocol used by IP-device section.

10. In the Assignment IP address field enter the address from which the broadcast in Multicast mode will be performed. Address is to be in range from 224.0.0.0 to 239.255.255.255 (3).
11. Click the Apply button to save the changes.

The rtsp Server object is now configured.

To connect to Server and display video in the video player that supports RTSP protocol, specify the address of data source in the format given in the table.

If captions are overlaid on the video (see Configuring captions display on a video image), they will be transmitted via RTSP server along with the video and can be displayed in the receiving app – VLC player.
