Formula is with the picture of other object computers of preview.But the formation that actually user can significantly experience divided frame needs
One section of waiting time is wanted, because the middle control computer that at this time network-type multi-computer switch must service may have more, network
All hardware resources (part related with image capture ability) can not be all dropped in segmentation picture by type multi-computer switch
In the formation in face, network-type multi-computer switch still have to retain a part hardware resource with take into account in other control computer its
He is user's (under single image mode), that is, network-type multi-computer switch still has to capture the picture of certain object computers
Face.Therefore, network-type multi-computer switch actually and can not once simultaneously capture be more than a certain number of object computers picture
Face, network-type multi-computer switch are only capable of sequentially capturing the picture of more object computers with the hardware resource of its part to service point
Cut the middle control computer under mode.Therefore, if user U between divided frame mode and single image mode continually back and forth
Switching by will cause user in use have some setbacks with it is inconvenient.
