Description
Technical field
The present invention relates to the communications field, in particular to a kind of video switching method, device
And system.
Background technology
During multipart video-meeting, either voice-activated pattern or chairman/director's control
Molding formula, there is a meeting-place as broadcast source.When the terminal output media stream, except the end
Other outer all participant terminals of end can all watch the video image of broadcast source terminal.Work as video conference
In when having the terminal-joined meeting of more than three, then either voice-activated is also in conference process
It is that broadcast source caused by controlling operation switches, video occurs in the terminal that can all cause to watch broadcast source
Switching.
Current video meeting image mode is divided into single-image and more picture both of which.In single-image
Under pattern, all meeting-place all can only see a certain meeting-place video image, it is impossible to see other meeting-place
Video image.A pre-set more picture layouts are seen in each meeting-place under more image modes,
The different meeting-place of different position displays, by multipoint controller (Multipoint Control Unit,
Referred to as MCU) terminal for participating in meeting is sent to after Unified coding.
Under single stroke surface model, when needed in video conference will watch broadcast source terminal on show
Image when switching to the image of current new broadcast source terminal, typically utilize video fast update
(VCU) and video freeze order (VCF) signaling is ordered, VCF is first passed through and freezes to watch broadcast source
Terminal on image, and stop sending video code flow to the terminal of viewing broadcast source, and to new
Broadcast source terminal and send VCU signalings, when MCU receives the new I frames broadcasted source terminal and sent
The terminal of viewing broadcast source is sent it to after video flowing.The terminal of viewing broadcast source, which receives, newly to be regarded
After frequency Media Stream, the original broadcast source images freezed on display are switched into new broadcast source
Video image plays out.
Essentially identical with single-image handling process above under more image modes, difference is freezed
No longer be watch broadcast source terminal, but in video conferencing system continuous presence unit it is wide
The sub-screen image where source video is broadcast, so present each video producer either single-image is still
Video switching in the case of more pictures is all to freeze video image from one to be suddenly switching in addition
One new video image, it is not fine on Consumer's Experience.
The problem of user experience is low when switching for video conference image in correlation technique, at present
Scheme is not efficiently solved also.
