  • the video is live video from the specified camera.
  • historical video may be requested in which case the video selection specifies when the video was created (e.g. date and time) .

  • the video camera system is a security camera system.
  • the video transmission system comprises a session controller for establishing a connection between the security system and the video streamer.
  • the session controller provides at least one video parameter to the video streamer to thereby control the quality of video transmitted to the mobile terminal. For example, video format type, frame size, bandwidth, frames per second, video quality.

  • the video from each of the cameras is monitored by the security system computer 132 in order to detect whether any motion has occurred in a monitored area.
  • an alert message is generated and sent to a mobile terminal.
  • the alert message typically consists of an image from the camera that relates to the alarm condition and a link which enables a browser software running on the mobile terminal to initiate a video session which results in transmission of live video from the relevant video camera.

  • the user operates the browser of the mobile terminal 110 to select a video camera and clicks on the link for the desired camera in order to start the live video stream process.
  • this provides a video request that specifies a camera.
  • the MVASS 132 contacts a central server 140 via Internet 120 over message path 162 in order to start the video stream.
  • the central server 140 has a command server 142 that acts a session controller and a video streamer 144 that has a transcoding server for transforming video from security system 130 into a format suitable for mobile terminal 110 and a streaming server 145 for controlling transmission of the video stream to the mobile terminal 110.
  • the command server 142 When the command server 142 is contacted by the MVASS PC 132 it configures the streaming server with the video stream parameters. These include the video format type, the frame size, bandwidth, frames per second, the IP address of the MVASS 132, the port that should be contacted of the MVASS 132 and the required video quality. MVASS 132 either stores video parameters specific to mobile terminal 110 or obtains them when the index page request is made. In this way, the command server 142 is able to configure the video streamer 144 - e.g.
  • the transcoder server 146 knows the native video format of the MVASS 132 and the destination video format of the mobile terminal 110 and the streaming server what frame size and how many frames per second should be sent and also the IP address of the MVASS 132 so it can access the video.
  • the video from the security systems 130 will be in motion jpeg (MJPEG) format and the transcoder server will code the MJPEG streams to MPEG-4 streams and packet it into RTSP.
  • the command server also obtains a session description that describes which resources of the video streamer 144 will produce the video stream so that the session description can be supplied to the mobile terminal.
  • the video streamer 144 then contacts the address of the MVASS 132 to obtain the video stream.

  • the streamer server 145 then starts the video stream to the mobile terminal 110 via streaming port 152 as indicated by- arrow 169.
  • Streaming port 152 is typically a UDP port obtained during RTSP negotiations. In this way, the quality of the video delivered to the mobile terminal can be high as 1. it matches the video capability of the mobile terminal; and 2. it is sent via ports configured for video transmission.

  • arrows 120a and 120b indicate that connections between the command server and the security systems and between the security systems and the mobile terminals are Internet type connections. These arrows do not imply in the case of the mobile terminals that the mobile terminals are able to access each of the security systems 130. Typically, there will be a security layer in place that allows only mobile terminals that are intended to have access to a particular system to be able to access those systems.
  • line 150 which is intended to illustrate a telecommunications network between the video streamer 144 and the mobile terminals 11On is not intended to imply that those mobile terminals 110 are able to receive video from all of the security systems 130.
  • the command server 142 is capable of configuring multiple sessions between the security systems 130 and the mobile terminal. To do this it allocates resources within the video streamer 146 by allocating resources on the transcoding servers 144 and the streaming servers 145 to a particular video session and creating session descriptions .

This is also important for keeping track of billing - e.g. to ensure that if the user has signed up for the service to be delivered via one carrier that it is not delivered via another carrier.
