Frequently during cable is linked into video meeting system, by send by the way of secondary flow by this transmission of video to far-end its
His meeting-place, such far-end is it will be seen that the computer output picture the same with this meeting-place, when each participant meeting
Field discusses some films in same meeting, is sitting on same computer limit just as everybody the when of material
Equally, very convenient.
In prior art, add video meeting system multiple meeting-place multipoint control unit (MCU,
Multipoint Control Unit) on hold a meeting, main meeting-place (such as main meeting-place A) can send master
Stream and audio stream, wherein, main flow occupies the transmission bandwidth of the overwhelming majority, therefore, it is possible on other meeting-place
Show preferable definition and fluency.But, the secondary flow logic of sending direction can also be opened in main meeting-place
Passage, is transferred to MCU by the desktop picture of local computing by this secondary flow logical channel, and other meeting-place
(such as: meeting-place B and meeting-place C) will open secondary flow and receive passage, and the secondary flow that meeting-place A sends is led to by MCU
Cross this secondary flow reception passage and be sent to other meeting-place (such as: meeting-place B and meeting-place C).
On the one hand, the bandwidth of main meeting-place A is fixing, therefore when meeting-place A sends secondary flow when, just
Can open secondary flow sendaisle, thus cause the main flow bandwidth sent to reduce, other meeting-place are (such as meeting-place B
Or meeting-place C) main flow of viewing meeting-place A time, it watches effect just to have in reduction, i.e. meeting it
He watches the video effect in the meeting-place of meeting-place A main flow and can be affected, and secondary flow fractional bandwidth also has
Limit, therefore the effect of secondary flow is the most poor.But secondary flow is usually and is used for watching computer desktop image,
Wherein a lot of contents belong to Word message, in the case of definition, fluency are poor, will cause far
End subscriber viewing effect is very poor, has had a strong impact on Consumer's Experience, therefore on the process strategy of secondary flow generally
Use the mode reducing frame per second to ensure definition, but sacrifice the fluency of picture.
In prior art after main meeting-place A opens secondary flow logical channel, when meeting-place B, C are by full frame
(secondary flow image on the display screen of meeting-place B, C, it is displayed in full screen), meeting-place B, C when mode watches secondary flow
The bandwidth of the only meeting-place band alleviating distention in middle-JIAO very small part secondary flow passage seen is transmitting secondary flow data,
On the computer desktop of far-end meeting B, C, the secondary flow data of display, cause data the most smooth because bandwidth is the least,
Just as sheet of showing slides, hopping sense is very strong, experiences very poor.Or, when main meeting-place A opens auxiliary
After stream logical channel, as meeting-place B, in the case of C does not watch secondary flow, because B, C open secondary flow
Passage occupies bandwidth, causes original main flow bandwidth to reduce, thus the video effect of main flow also can reduce,
Affect Consumer's Experience.
