Abstract

The invention relates to remote control technology for a plurality of player terminals and provides a player remote control system which is easier in system extension. The player remote control system comprises client control modules and the player terminals, and is characterized in that the player remote control system also comprises a message forwarding module, wherein the message forwarding module is connected with the client control modules and the player terminals and used for receiving related information of the player terminals, maintaining a device identification list, transmitting the related information of the player terminals to the client control modules, determining a target player terminal by searching through the device identification list after receiving control data packets transmitted by the client control modules, and forwarding a control command; and the related information includes IP addresses and ports, device identifier IDs and device types. Correspondingly, the invention also provides a player remote control method. The player remote control system and the player remote control method realize centralized and unified control management of the plurality of client control modules on the plurality of different player terminals.

Description

Player tele-control system and player long-range control method

Technical field

The present invention relates to remote control technology to many player terminals.

Background technology

As everyone knows, the audio/video player system that on market, is seen everywhere many at present, as: the advertisement machine in supermarket, the propaganda demonstration equipment on the airport also has watch-dog of each crossing and bank, charge station or the like.Because the rise of the Internet, therefore the user can just can control these equipment in office of company or family by a PC end software, as changing play content, associative operations such as controls playing speed, also can carry out unified management, realize the purpose of a control centre many Play Systems.Traditional Long-distance Control is based on point-to-point mechanism, be that PC1 wants to control player terminal 1, player terminal 2, then directly send control information respectively to player terminal 1 and player terminal 2, like this, whole system has significant limitation, be not easy to expansion,, then set up a new communication line again again if increase new device end more later.

Summary of the invention

Technical problem to be solved by this invention is that a kind of player tele-control system and player long-range control method that is easier to system extension is provided.

The technical scheme that is adopted that the present invention solves the problems of the technologies described above is, the player tele-control system comprises client control module, player terminal, it is characterized in that, also comprise message transmitting module, described message transmitting module links to each other with client control module, player terminal; Message transmitting module is used to receive the relevant information of player terminal and keeps the device identification tabulation, sends the relevant information that receives player terminal to the client control module; After receiving the control data bag that the client control module sends, determine the destination player terminal by searching the device identification tabulation, and transmit control command; Described relevant information comprises IP address and port, device identifier ID, device type.

The player long-range control method may further comprise the steps:,

F, player terminal are registered the relevant information of this player terminal to message transmitting module by network; Described relevant information comprises IP address and port, device identifier ID, device type;

G, message transmitting module receive the relevant information of the player terminal of player terminal transmission, the identification list of keeping, update the equipment;

H, client control module are obtained the relevant information of all player terminals from message transmitting module;

I, client control module send the control data bag to message transmitting module, and described control data bag includes player terminal device identifier ID, and the control operation order;

J, message transmitting module resolution data bag are searched corresponding IP address and port according to identifier ID in the device identification tabulation, transmit the control operation order to player terminal.

The invention has the beneficial effects as follows, realized many client control modules to many different player terminals concentrate, unified control and management, the increase of player terminal or minimizing are connected can not for the hardware of client control module and be impacted, same, the increase of client control module or minimizing are connected also can not for the hardware of player terminal and be impacted.

Description of drawings

Fig. 1 is a system schematic of the present invention.

Embodiment

As shown in Figure 1, system comprise plurality of client end control module (client control module 1,2 ... n), message transmitting module, some player terminals (player terminal 1,2 ... n), wherein player terminal is made up of player receiver module and playing module.Message transmitting module links to each other with plurality of client end control module, some player terminals.

The concrete flow process of long-range control method is as follows:

After player terminal starts, register oneself relevant information to message transmitting module by network, as: the device identifier ID of this player terminal, device type, IP address and port etc.;

Message transmitting module starts the back and opens two threads, a thread is used for monitoring the data that send over from player terminal, another thread is used for monitoring the data that send from the subscription client Control Software, after receiving the information that player terminal sends, the equipment of keeping a player indicates tabulation, manages corresponding information respectively;

After the client control module starts, a mutual process is also arranged, obtain the relevant information of all player terminals from message transmitting module with message transmitting module, as: device identifier ID, device type, IP address and port.Can control separately certain player terminal then, send the packet of some controls to the player terminal of fixed ip address, content in the bag can have these information: the device identifier ID of destination player, certain title of a film, the pattern (HDMI or Ypbpr etc.) of video output also has relevant control command, as: F.F., rewind down stops to wait operation;

After message transmitting module received the packet that the client control module sends, the resolving of being correlated with was searched purpose IP address and port by device identifier ID, determines the destination player terminal, carries out repeating process again;

The player receiver module is received corresponding control information by network communication mode from message transmitting module, by socket (socket) communication mode information is passed to player again, and player carries out the control corresponding operation.

Claims

[claim 1] player tele-control system comprises client control module, player terminal, it is characterized in that, also comprises message transmitting module, and described message transmitting module links to each other with client control module, player terminal; Described message transmitting module is used to receive the relevant information of player terminal and keeps the device identification tabulation, sends the relevant information that receives player terminal to the client control module; After receiving the control data bag that the client control module sends, determine the destination player terminal by searching the device identification tabulation, and transmit control command; Described relevant information comprises IP address and port, device identifier ID, device type.
[claim 2] player long-range control method is characterized in that, may further comprise the steps:
