Embodiment
The invention provides a kind of method and system of content preview of streaming media.
Describe the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes integrated management server 100, media server 200, preview server 300 and client computer 400.
Wherein, integrated management server 100 is accepted the register requirement of client computer 400, and writes down the information of each client computer: comprise ID number of client computer, IP, network speeds etc., integrated management server 400 these information of record are so that rationally distribute to client network.
Integrated management server 100 is also accepted the register requirement of media server 200, and generation the rendition list, all need to register before the media server 200 issue programs of each program to integrated management server, log-on message comprises: program ID, programm name, size, the stream media format of transmission, information such as media server IP, integrated management server 100 generates a rendition list according to the information of the registration of all media servers, offers client computer 400 and selects.Client computer 400 is according to the ID request program source of the rendition list.
Media server 200 must be registered program source to integrated management server 100: promptly to integrated management server registration program source information, comprise program ID, programm name, size, the stream media format of transmission, information such as program source server ip.Media server 200 provides program data to client computer 400 and preview server 300 in addition: media server 200 is to the initial data of preview server 300 and client computer 400 transmission programs.
Preview server 300 is to integrated management server request program source server, the program source server address that provides according to integrated management server is connected to the media server 200 of appointment, and to the real-time program data of asking current broadcast of this media server, and regularly generate preview data according to predefined preview demand, such as current point-to-point (Peer to Peer) living broadcast buffering 120 second flow media datas, in general per second has 15 frames, then one have 1800 frame data, preview server reads the frame data of certain intervals from these 1800 frame data according to the preview demand, suppose to preestablish needs 20 frame preview datas, preview server 300 every interval 6 seconds in 120 seconds then, per second reads first frame data and comes out, and is kept in the internal memory.Preview server 300 is accepted the preview request of client computer 400, and returns preview data for client computer 400.
Based on the invention described above system, the invention also discloses a kind of method of preview Streaming Media.Fig. 2 is a data flowchart of the present invention, below explanation specific implementation step of the present invention.The present invention mainly comprises 2 parts:
A: client and integrated management server, preview server mutual;
B: media server, preview server and integrated management server mutual;
The specific implementation step of A and B below will be described respectively.
The performing step of A part is as follows:
Steps A 50: client computer need arrive the integrated management server registration.Client computer is with information such as ID, IP address information, the bandwidth notice integrated management server of oneself.
Steps A 100: client computer is to integrated management server request the rendition list.
Steps A 200: integrated management server is accepted user's request, and sends a series of the rendition lists to client computer.
Steps A 300: the user need to select the program ID of preview, by the preview data of client to preview server request program ID.
Steps A 400: preview server sends preview data according to program ID to client computer.
Steps A 500: client computer receives the preview data that preview server sends.
Steps A 600: client computer is play the preview data that receives, client computer is according to the quantity and the frame data invokes media players of frame, (as MEDIA PLAYER), and by each frame data of certain time interval loop play: 10 frame data for example, player is play by 1 second speed of every frame period.
Being achieved as follows of B part:
Step B50: various media servers (program source server) are to the integrated management server registration, and promptly media server notifies integrated management server its service content.
Step B60: accept the media server registration, and distribute program ID, write down the information of this media server, as this media server IP address, information such as related-program introduction.
Step B100: preview server is to the media server address of integrated management server request previewing program ID.
Step B200: integrated management server returns the media server address of program ID to preview server.
Step B300: preview server is to the media server request preview data of program ID.
Step B400: media server returns the data of program ID to preview server.
Step B500: preview server program receiving ID data, and generate preview data, and this preview data is stored in the internal memory.Preview server generates data according to predefined preview time t_preview and preview frame number f_preview, for example, if set preview time t_preview=120 and preview frame number f_preview=20, then preview server is every first frame of 6 seconds read datas, and these frame data are stored in the internal memory.
