Method for screen transmission between computer and mobile equipment through incremental mixed compressed encoding

Abstract

The invention discloses a method for screen transmission between a computer and mobile equipment through incremental mixed compressed encoding. The method comprises the following steps of: acquiring screen data on the computer, and performing image encoding on the acquired screen data to form screen frame image data; performing incremental computation on the current screen frame image datum and the previous screen frame image datum by using an incremental computation method, and acquiring incremental data; performing mixed compressed encoding on the current screen frame image datum and the incremental data to form an incremental data packet; and comparing the size of the incremental data packet with the size of the current screen frame image datum, and transmitting the smaller one to the mobile equipment.

Description

technical field [0001] The invention relates to a method for screen transmission between a computer and a mobile device through incremental hybrid compression coding, especially through the method of incremental hybrid compression coding, which reduces the amount of transmitted data on the premise of ensuring the quality of the screen image, and belongs to computer image processing and Network transmission technology field. Background technique [0002] In the existing screen transmission method, there are mainly two methods for processing screen data: image mode and video mode. [0003] In the image mode, the screen data is collected into image data frames at a certain frequency for processing and transmission. The advantage of this method is that image data encoding is widely supported by equipment, and it is convenient to control the transmission frame rate and the amount of transmitted data. The limitation of this method is that when high image quality is requir...

Problems solved by technology

The limitation of this method is that stream encoding requires relatively high computing and transmission capabilities of the device, and it is often difficult to apply to situations with low device processing capabilities.

[0005] With the rapid development of science and technology, new mobile devices such as smartphones and tablets are constantly emerging. Compared with ordinary computers, these devices have lower overall hardware performance, poorer computing power, and smaller screen sizes, etc.
