Description
Technical field
The present invention relates to conference system technical fields, more particularly to a kind of remote terminal and entity main meeting-place recorded broadcast equipment
Real-time interactive have a meeting system.
Background technique
With coding and the development of compressionism and the high speed development of digital network, video conferencing system occurs simultaneously
It enters into the market, the international standard (H.320) from phase at beginning of the nineties in last century first set about video conferencing system is obtained by simultaneously
Since implementation, video conferencing system is more and more widely used, meanwhile, provided voice experience, video tastes
Demand also more and more attention has been paid to.For voice experience demand side, will the evolution in terms of high fidelity speech reappears, and regard
It will the evolution in terms of high-resolution, wide viewing angle in terms of frequency demand for experience.
However, existing video conferencing system needs that a Remote Video Conference hardware terminal is arranged in each meeting-place, if
It is related to multiple participants and is in different regions position, not only needs more Remote Video Conference hardware terminals, carried out video council
Discuss at high cost, when can not reach meeting-place especially for certain personnels participating in the meeting (e.g., welcome guest or leader), can not often attend a meeting the meeting
The phenomenon that discussing, meeting caused not hold normally.Main meeting-place hardware is identical with sub-venue hardware terminal eventually, leads to main meeting-place
The broadcast of switching instructor in broadcasting's picture of multimachine position picture and electronic script
In addition, the video conferencing system of existing pure software, lacks hardware, all terminals are using computer or mobile phone same
Head portrait is shown in screen, without main meeting-place, also lacks the screen switching function of main meeting-place, thus without computer, mobile phone and master
The view of the more screen switchings in meeting-place, audio interaction.
Summary of the invention
It has a meeting the purpose of the present invention is to provide a kind of remote terminal and the real-time interactive of entity main meeting-place recorded broadcast equipment and is
System cannot reach specified meeting-place for important personnel participating in the meeting for solving conference system in the prior art, just can not normally hold
The problem of meeting.
In order to achieve the above objects and other related objects, the present invention provides a kind of remote terminal and sets with the recorded broadcast of entity main meeting-place
Standby real-time interactive is had a meeting system, is interacted for video and audio between entity main meeting-place recorded broadcast equipment and each remote terminal and picture and text
Interaction, comprising:
Entity main meeting-place recorded broadcast equipment, for switching between more scenic pictures and electronic script between more scenic pictures
And switching result is subjected to coded treatment, live video stream is generated, the video flowing is uploaded to server；
Entity main meeting-place display device connects entity main meeting-place recorded broadcast equipment or/and server, for receiving and presenting institute
Live video stream after stating the switching of entity main meeting-place display device, alternatively, for receiving the entity for decoding the server forwarding
The live video stream and picture and text of the acquisition of terminal used in the live video stream of main meeting-place recorded broadcast equipment and all remote participants
Data, and the different display windows in same interface play simultaneously；
The terminal that remote participant uses includes at least the smart phone or/and computer of camera function, before being preinstalled with
Hold interactive applications, the live video stream for the entity main meeting-place recorded broadcast equipment which receives and decoding server forwards and institute
The live video stream and graph text information for thering is terminal used in remote participant to acquire, and institute is played simultaneously in different display windows
State live video stream and graph text information；The live video stream and graph text information for being also used to send the acquisition of this terminal are to server；
Server is equipped with backstage interactive applications, connects the entity main meeting-place recorded broadcast equipment to receive and forward master
The live video stream in meeting-place is connected the terminal that the remote participant uses and is believed with the video flowing and picture and text that receive and forward participant
Breath.
The system as described above, remote terminal of the invention and the real-time interactive of entity main meeting-place recorded broadcast equipment are had a meeting, has
Below the utility model has the advantages that
The terminal (mobile phone, computer or tablet device) that the present invention is used by remote participant can be built between main meeting-place
Vertical video link, achievees the purpose that teleconference so that personnel participating in the meeting no matter where, meeting can be participated in by network in time
View；Wherein, recorded broadcast equipment in entity main meeting-place switches between more scenic pictures and electronic script between more scenic pictures and will
Switching result carries out coded treatment and generates live video stream, and switching display interacts convenient for main meeting-place with remote participant face-to-face.
In addition, the present invention only needs a Remote Video Conference hardware terminal to be set to main meeting-place, avoids each meeting-place and require to install
Remote Video Conference hardware terminal, caused by the very expensive phenomenon of conference system cost.Meanwhile the end that remote participant uses
The form that graph text information can be used in end interacts, and realizes and interacting between the personnel participating in the meeting of main meeting-place, remote participant.
