Method and apparatus for multiple image display control

Abstract

The embodiment of the present invention discloses a method and device for multi-screen control and display. The method for multi-screen control and display includes: receiving a request carrying a model ID, and the model ID is used to indicate the layout of the screen; according to the model ID, obtaining Corresponding screen layout model; calling a pre-stored calling program that matches the screen layout model, instructing the display device to display screens according to the screen layout model. The device for multi-picture control and display includes: a receiving module, used to receive a request carrying a model identifier, and the model identifier is used to indicate the layout of the screen; an obtaining module, used to obtain a corresponding screen layout model according to the model identifier; a calling module , for calling a pre-stored calling program that matches the screen layout model, and instructing the terminal to display a screen according to the screen layout model. The embodiment of the present invention improves the indication efficiency of the sub-window information during the video conference and reduces the processing complexity.

Description

technical field [0001] Embodiments of the present invention relate to the field of network communication technologies, and in particular, to a method and device for controlling and displaying multiple screens. Background technique [0002] In a video conferencing system, a series of information such as identification, starting position, size, and stacking order of each sub-window need to be transmitted between the various components of the conference system, and between the terminal and the conference system. The sub-window identifier is used to modify the properties of the sub-window, the starting position and size determine the window layout, and the stacking order determines the stacking order when multiple sub-windows overlap. In the case of a single window, part of this information can be omitted, but in the case of multiple screens, such as a window layout of 1 large and 5 small windows, the above information cannot be omitted, otherwise it will cause inconsistencies i...

AI Technical Summary

Problems solved by technology

[0020] Since the instruction information is transmitted between the two components, the transmission efficiency is low because the message is too long, and the encoding process of the sender and the decoding process of the receiver are also relatively complicated. packet loss problem

Between the terminal and the conference system, and between the internal components of the conference system, it is necessary to decode the mode selected by the user into a series of dimensional descriptions such as sub-window identification, starting position, size, stacking order, etc., and then restore to the actual display mode. Or after processing, encode it into a series of dimensional descriptions such as sub-window identification, starting position, size, stacking order, etc., to indicate to the next component of the conference system, which is very inconvenient to use

The more complex the multi-screen layout, the more serious the above problems
