2) resource management system distributes and examines resource according to the operating position of device resource in the system;
3) resource management system is set up and is examined link according to the resource of examining of being distributed;
4) according to the link of examining that has generated,, be modulated to the respective inner frequency channels of cable TV, utilize the TV corresponding channel to examine the signal of examining on the link.
Further, step 1) and step 2 in step (2)) in when accepting resource bid and distribution and examine resource, according to the resource bid that receives, check the operating position of resource in the existing system, those resources are used, and those resources are not used, and judge the condition of the material do not use resource whether to satisfy the demand to examine, as satisfying, then distribute; Otherwise refusal distributes, and returns information.Described resource comprises video server decoding channels, video tape recorder, matrix circuit, radio-frequency modulator, and these resources are shared resources, can come dynamic assignment according to operating position.
Further again, in the step 3) of step (2), set up when examining link, according to the resource of examining of the material distribution that needs are examined, judge, judge whether to generate and examine link,, then allow if the generation of this link does not influence the normal operation of other request in the existing system; Otherwise, return.
Further again, when the signal that will examine material in the step 4) of step (2) carries out rf modulations, be modulated to the frequency range of respective inner cable TV, and in cable television network transmission video signal, realize long-range examining.
Further again, when examining video material that client examines needs in the step (3) and examining, can control material broadcast, suspend, stop, F.F., rewind down, frame are advanced, frame moves back.The described client of examining is a cable TV.
Further, step 2) by network, utilize the network resource scheduling center in, according to the encoding characteristics of video file, video file is sent to when examining client in the mode of stream, the concrete grammar of employing is:
1) the network resource scheduling center accepts request, and watches the network behaviour in service, examines if can carry out network, then Resources allocation; Otherwise, return;
2) encoding characteristics, compressed format and the storage characteristics of extraction video file;
3) according to 2) information judge that whether video file can send to client with the form of stream, if fruit can, then directly send; Otherwise, carry out the code stream conversion earlier, and then send.
Further again, described network is the Internet or local area network (LAN), and the described client of examining is to show the video material of being examined by host computer and display.
Effect of the present invention is: adopt method of the present invention, can improve the efficient that video material is examined greatly, can reduce taking of resource, improve resource utilization, reduce the investment of device resource, and can carry out long-range examining, can also utilize inner cable TV to finish collaborative examining.
