Description
Technical field
The utility model relates to video communication and video conference field, especially, relates to a kind of real-time interactive high-definition network video communication system.
Background technology
Along with the technique of internet fast development, popularizing of the integration of three networks will become the application of main flow by image information data such as the two-way real-time Transmission high definition audio in internet, video, picture and text, be also the developing direction of high-definition network video.
Existing video conferencing system mainly adopts and H.320 arrives H.323 communications protocol; Minority producer is also to the Session Initiation Protocol transition, and SIP is the network communication protocol that is similar to the text based agreement of HTTP, also has a large amount of technical bottlenecks to be difficult to merge with the internet.H.323 wait serial network communication protocol owing to H.320 arriving, be based on radio and television and the large System Development of telephonic communication two, standard is formulated by producer.Therefore also must adopt some switching softwares with Internet connection, be difficult to adapt to fast development.And the software of each producer, hardware etc. are not identical, thereby coding and decoding all needs separately the special equipment of manufacturer just can complete, and this is the principal element that causes the video communication transmission can not popularize because of high cost eventually.
The general centralized processing system that adopts of existing video conferencing system.Its main cause is in order to continue to use original hardware and software framework.One, existing video conferencing system mainly originates from radio and television and telephonic communication two large system, and the network communication protocol standard of system is also to be formulated by these producers.According to these communication protocol standards and technical conditions at that time, can only research and develop deisgn product based on integrated system.Two, as shown in Figure 1, existing video conferencing system adopts the hardware structure of a plurality of terminals of main frame band, and terminal does not have data-handling capacity, is all analog interface mostly as video camera, VGA interface etc., and calculation process is mainly carried out on main frame.As all being connected to focus on an encoding and decoding box, video camera and other video source realize receipts.If realize that the above video communication of three points also needs a superpower PC (MCU) of operational capability to complete.Realize that more video watches a function, can only adopt the dilatation of cascade stack stacked group net, each grade connects stackingly all can bring in various degree loss and time-delay to vision signal, and these hardware, software are often all very expensive, cause equipment price high.And system is more complicated, brings more destabilizing factor to system thus.
Existing video conferencing system generally adopts the H.239 double-current video of communications protocol transmission, can only video of one-way transmission and a PPT text picture video.Also only have at present minority video conference producer can realize one-way transmission double fluid video capability.According to communications protocol designed system H.239, can't realize passing a plurality of videos or transmit a plurality of code stream video requirements in a video flowing at all.Adopt the video conference control mode of the mode of operation of radio and television can only realize simple conferencing function, adapt to the data message data transmission function demands such as high definition audio, video, picture and text such as remote teaching, tele-medicine, long-range judicial evidence collection and remote operation industrial control equipment, existing video conference mode of operation can't realize.
Storage, relay and the playback of video conferencing system at present need to configure third-party recorded broadcast server and could realize.Because being based on telecommunication standard, agreement H.323 formulates, and poor compatibility between the internet, coding and decoding must adopt special equipment just can complete.Use very complicated difficulty if need the functions such as realization is recorded, issue, online request, must be in the main meeting-place of configuration MCU, the recorded broadcast server that increase hardware, software are integrated namely only has the main meeting-place that has configured MCU and recorded broadcast server just can carry out relay, storage and the playback of meeting.
In summary, existing video conferencing system exists poor compatibility, end equipment large and complicated, and all computing functions concentrate on all that a CPU is upper to be processed, and is high to the configuration requirement of CPU, expensive, the shortcoming such as processing when can't realize more video.At present, the video conferencing system that can process in real time 16 road videos is extremely expensive; And, not yet see the video conferencing system that can process in real time the video more than 24 tunnel and emerge.
The utility model content
The utility model purpose be to provide a kind of compatibility good, realize that cost is little, cost is low, video quality is good and can realize that multi-channel video processes, do not limit the real-time interactive high-definition network video communication system of the number of visiting people simultaneously, with solve existing video communications system poor compatibility, end equipment is large and the price of complexity and video communications system is extremely expensive, the technical problem that can't realize multi-channel video communication.
For achieving the above object, the utility model provides a kind of real-time interactive high-definition network video communication system, comprising:
