Method and apparatus for multiple image display control

Abstract

The embodiment of the invention discloses a method and a device used for a multi-picture plane control display. The method used for the multi-picture plane control display comprises the steps as follows: a request carrying a model mark is received; the model mark is used for indicating the layout of the picture plane; corresponding picture plane layout model is gained according to the model mark; a calling program which is memorized in advance and matched with the picture plane layout model is called; a display device is indicated to display the picture plane according to the picture plane layout model. The device used for multi-picture plane control display comprises a receiving module which is used for receiving the request that carries the model mark that is used for indicating the picture plane layout, a gaining module which is used for gaining corresponding picture plane layout model according to the model mark, a calling module which is used for calling the calling program which is memorized in advance and matched with the picture plane layout model, and an indicating terminal which displays the picture plane according to the picture plane layout model. The method and the device of the embodiment of the invention improve the indicating efficiency of the sub-window information during the video conference and reduce 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...

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
