Data processing method, image demonstration method, data processing apparatus and demonstration equipment

Abstract

The invention provides a data processing method, an image demonstration method, a data processing apparatus and demonstration equipment. The data processing method comprises: when a first picture is being displayed at a first display, image data of the first picture displayed at the first display are obtained; compressed encoding is carried out on the obtained image data to obtain compression data; and the compression data are stored in a first memory temporarily; the compression data in the first memory are transmitted to the demonstration equipment connected with the display equipment, so that the a second picture corresponding to the compression data can be obtained synchronously from a second memory of the demonstration equipment and the second picture can be displayed at a second display of the demonstration equipment. The second picture and the first picture are identical to each other approximately. According to the technical scheme of the embodiment of the invention, synchronous demonstration can be carried out rapidly, thereby improving the using experience of the user.

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically, to a data processing method, an image presentation method, a data processing device, and a presentation device. Background technique [0002] With the development of electronic technology, various electronic devices have appeared, such as notebook computers, intelligent communication terminals, and personal digital assistants. Videos, games, presentations, etc. can be played on these electronic devices. However, due to the small size of the screen of the electronic device, or the limitation of the power consumption and performance of the electronic device, in some cases it is necessary to display the image displayed on the screen of the electronic device (that is, the display device) on a screen such as a TV, a projector, etc. other electronic equipment (i.e. presentation equipment). [0003] The electronic device usually has a screen capture function, so tha...

AI Technical Summary

Problems solved by technology

[0004] The demo performance provided by the existing synchronous demonstration scheme is poor, and the highest frame rate can only be 1-2fps (frame per second), which cannot meet the needs of real-time synchronous demonstration, especially for video playback, games and other fast-changing screen, completely failing to achieve the purpose of real-time demonstration
