The specific embodiment mode
The present invention is described in detail below in conjunction with specific embodiments and the drawings.
Basic principle of the present invention is to utilize in the TV conference system equipment such as original GK, MCU, conference dispatching system and terminal and increase the programme televised live source and encoding device provides technical solution of the present invention required programme televised live source, by MCU with the program of program source to whole meeting broadcast, terminal equipment passes through to dial and makes meeting number insert meeting to watch program, realize providing the channel live program in the mode of dialing to the terminal use.
The system group network of technical solution of the present invention as shown in Figure 2, wherein the function of each assembly is as follows:
GK (gateway system E1): GK mainly is responsible for the parsing of network number.When terminal was dialed conference number, GK received the request of terminal, and the address that meeting number is resolved to MCU (multipoint control unit E2) returns to terminal, and terminal connects MCU and watches meeting just at live video-audio program;
MCU:MCU is responsible for sending video/audio signal to terminal, can carry out capability negotiation with terminal when transmission, selects appropriate transmission rate.When programme televised live is watched in a terminal desire adding meeting, call out the conference number (this number is by conference dispatching system E4 definition) of this program correspondence earlier, number is resolved by GK (E1) and is returned the MCU address to terminal, terminal then connects MCU by the address of returning, determine traffic rate, receive the video/audio signal that MCU transmits;
Programme televised live source (E3): the programme televised live signal is responsible for receiving in the programme televised live source, and reception is obtained the real-time input coding equipment of programme signal, and encoding device is encoded into programme signal the IP bag of RTP (RTP) form;
Conference dispatching system (E4): conference dispatching system is responsible for the definition and the scheduling of meeting.At first need to define a meeting, meeting has the anonymous site of some (can set), and the program stream that encoding device (E6) is exported is passed through MCU as a meeting-place broadcast to meeting.If programme channel, each programme channel (corresponding meeting) has the meeting number of an access.
Terminal (E5): when meeting was held, terminal can insert the meeting-place by the mode of call-conference number, watched the programme televised live of meeting broadcasting.
Encoding device (E6): the input in encoding device program receiving source is encoded into the IP bag of RTP form as output with programme signal; This equipment is broadcasted to the meeting of holding by MCU as program source.
In the said equipment, GK, MCU, conference dispatching system and terminal constitute a TV conference system devices needed on IP network, and these equipment belong to the existing equipment in the TV conference system.Program source that increases newly and encoding device provide technical solution of the present invention required programme televised live source.
The flow process that the terminal click to dial is watched the channel live program is as shown in Figure 3:
Step 1, MCU are registered on the GK;
Step 2, conference dispatching system (E4) at first define a meeting, and program source (being made up of jointly equipment E3 and E6) is added to the meeting-place; When conference setup, conference dispatching system can be conference number that inserts meeting of each meeting definition, and terminal equipment can pass through to dial and makes conference number access meeting watch program.Meeting number is stored on the conference dispatching system with the related information of meeting;
Step 3, when program source provides multiple programs, need a plurality of meetings of definition, each meeting is added a programs as the meeting-place;
Step 4, conference dispatching system dispatching MCU are held a meeting, and MCU broadcasts the program of program source to whole meeting.
Step 5, conference terminal are dialed conference number, GK (E1) receives this number, it is resolved to return to terminal (incidence relation of meeting number and MCU address is set when the conference dispatching system E4 conference setup, and GK need inquire about the MCU of this meeting to conference dispatching system (E4)) after the address information of MCU;
Step 6, conference terminal connect MCU after receiving this address;
The video frequency program that step 7, MCU (E2) will broadcast sends to terminal.
In order to provide more friendly to the user and programming access mode easily, can allow the user select to watch with program is distributed on the Web server.The flow process of issuing the channel live program to the terminal use by the Web form web page is as shown in Figure 5:
At first MCU and conference terminal are registered to GK, by Web server issue program (the related meeting of each programme televised live), set conference number.Web server is issued program with Web web page interlinkage formula, terminal is if watch programme televised live, can be to Web server request the rendition list, behind the rendition list that obtains returning, the channel link that the user selects to want to watch is clicked, the corresponding conference number of terminal call, GK (E1) resolves this number (in resolving, GK need inquire about the MCU number of holding a meeting to conference dispatching system E4), the address of MCU (E2) is returned to terminal, terminal connects MCU, and MCU is to the audio/video program of terminal transmission program source, and terminal is watched program.
In order to realize visiting the function of Web service, conference terminal must have the browser of supporting the http agreement, and supports the mode call number by clickable hyperlinks.
