GNSS system for operating vehicles -
Video communication protocol
1 Scope
This standard specifies the protocol basis and communication protocol between
the vehicle-mounted video terminal and the video platform in the satellite
positioning system of the road transport vehicle, the code-stream
communication between the audio-video stream server and the client’s playing
software, the communication protocol basis, communication protocol flow,
constant definition, protocol data volume’s format between the video platforms.
This standard is applicable to the transmission of audio-video data between the
vehicle-mounted video terminal of the satellite positioning system of the road
transport vehicle and the enterprise’s video surveillance platform, as well as the
exchange and sharing of audio-video resources between different video
platforms.

4.1 Basic agreement of protocol
The communication method, data type, transmission rules and message
composition of the protocol are in accordance with the requirements of clause
4 of JT/T 808-2011.
The communication connection mode of the signaling data message in the
protocol is in accordance with the requirements of clause 5 of JT/T 808-2011.
The message processing mechanism of the signaling data message in the
protocol is in accordance with the requirements of clause 6 of JT/T 808-2011.
The encryption mechanism of the signaling data message in the protocol is in
accordance with the requirements of clause 7 of JT/T 808-2011.
The parties to the protocol for platform and terminal communication shall meet
the following requirements.
- Unless otherwise specified, all messages shall be responded;
- If a dedicated response message is not explicitly specified, it shall use the
universal response reply;
- For messages with sub-packet, the responder shall respond on a packet-
by-packet basis for each sub-packet message.
4.2 Convention on real-time audio-video transmission channel
A real-time audio-video transmission channel may either transmit one channel
of video information or one channel of audio information, or transmit one
channel of video information and one channel of audio information. There are
two types of conventions on the real-time audio-video transmission channel.
- When using the TCP method, each TCP connection may carry multiple
audio-video channels. If there is no data transmission within the set timeout
period, both the terminal and the monitoring center may actively close the
TCP connection which is used for audio-video data transmission.
- When using UDP method, each UDP port may carry multiple audio-video
channels.
