specific Embodiment approach 1

[0012] Specific embodiment 1: The multimedia distributed command and dispatch system based on mobile ad hoc network described in this embodiment is composed of multiple mobile terminals, each of which has the same structure, and the multiple mobile terminals adopt the mobile ad hoc network Form a network system, any one of multiple mobile terminals can be used as a control terminal to send control commands to other mobile terminals.

specific Embodiment approach 2

[0013] Specific implementation mode two: combination figure 1 Describe this embodiment, the difference between this embodiment and the mobile ad hoc network-based multimedia distributed command and dispatch system described in the first embodiment is that the mobile terminal is composed of the following parts:

[0014] The multimedia unit 1 is used to collect multimedia information according to the command sent by the control unit 3, convert the multimedia information into a multimedia stream, and then send it to the wireless transceiver unit 2 by the multimedia unit 1; or send it to the wireless transceiver unit 2 Decode the multimedia stream and output the multimedia information;

[0015] The wireless transceiver unit 2 is used to find the route according to the command sent by the control unit 3, and select the best path, and send the received multimedia stream or control command according to the selected best path; The multimedia streams or control instructions sent by ot...

specific Embodiment approach 3

[0027] Specific embodiment three, the difference between this embodiment and the multimedia distributed command and dispatch system based on mobile ad hoc network described in embodiment two is that the multimedia unit 1 is composed of a pickup 1-1, a broadcaster 1-2, Camera 1-3, display screen 1-4, multimedia encoder 1-5, multimedia decoder 1-6, multimedia server 1-7 and multimedia client 1-8;

[0028] Wherein the pickup 1-1 is used for collecting audio information, and sends the collected audio information to the multimedia encoder 1-5;

[0029] The camera 1-3 is used to collect video information, and sends the collected video information to the multimedia encoder 1-5;

[0030] Multimedia encoder 1-5, is used for setting the multimedia parameter of encoding, and described multimedia parameter comprises the mode of information encoding, stream type, image parameter, video format, video resolution, video transmission rate, video frame rate, video stream Type, audio mode and a...

Abstract

The invention discloses a multimedia distribution command and control system based on a mobile ad hoc network, relating to the technical field of mobile network multi-hop communication and a multimedia stream transmission method in communication technology. The system of the invention solves the problems brought about by the existing and traditional cluster mode command and control system that only voice transmission can be carried out, the command system can not be flexibly and quickly transferred, etc. The system consists of a plurality of movable terminals with the same configuration; the terminals can be fast and spontaneously organized to form mobile ad hoc networks, can realize the transmission of the multimedia stream through a multi-hop router, and can realize the aim of conducting command and modulation to other terminals by inputting control instructions to various mobile terminals. In the dispersed network constitution, a commander or a mobile terminal is allowed to conducting seamless interoperability to other terminals; the system supports transmission ways of singlecast and multicast, etc., the terminals of the system have equivalency, therefore, the system has good universality and expandability.

Description

technical field [0001] The invention relates to the technical field of mobile network multi-hop communication and multimedia stream transmission method in the communication technology. Background technique [0002] Traditional command and dispatch communication systems are generally clustered, that is, they have a center. Usually, the network infrastructure must be set up in advance to make the entire system run normally. For example, a cellular mobile communication system must be supported by functional facilities such as base stations and mobile switching centers; wireless local area networks generally work in the mode of access points and wired backbone networks. But for some special application occasions, the centered mobile communication technology is not competent. For example, the rapid deployment and advancement of troops on the battlefield, rescue after large-scale disasters such as earthquakes or floods, field expeditions, remote mine operations, and large-scale c...
