Method and system for instantaneous transmission of screen images

Abstract

The invention relates to the field of image processing and discloses a method and a system for instantaneous transmission of screen images, which solves the problems of low frame rate, image katon andfragmentation caused by simple transmission of screen captured pictures. The system of the invention comprises a screen data acquisition module, which is used for acquiring parameters of the screen and currently displayed frame data, and storing the acquired frame data in a memory; the video data encoding module is used for encoding the adjacent frame data in the memory according to the parameters of the screen. The code stream synthesizing module synthesizes the encoded data according to the set transport stream format to generate streaming media data suitable for network transmission. The network sending module is used for packaging the synthesized stream media data into network packets according to the live stream address and the transmission protocol to be transmitted, and sending thepackets to the live stream address for downloading and playing by the terminal stream media player. The invention is applicable to timing transmission of television screen images.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and system for instantly transmitting screen images. Background technique [0002] The function of instantly transmitting the screen image of the current device is an important function of consumer electronic devices, such as smart TVs, smart phones, set-top boxes, etc., and its core function is to transmit the currently displayed screen image to a remote device for display, and also It's screen sharing. There are many usage scenarios for screen sharing, and it is widely used in scenarios such as video conferencing, remote assistance, and online services. To share the screen, you must first obtain the screen of the shared device, then encode it, then synthesize the audio and video into a stream format that needs to be transmitted, and finally select an appropriate transmission method to send it to each media terminal through the network, and the media terminal is respons...

Problems solved by technology

[0003] Because the mainstream Android TV system generally only provides an interface for capturing an image on the screen, and obtaining the image is time-consuming and inefficient, and the effects of different platforms vary greatly, resulting in the screen transfer effect if realized based on the screen capture interface of the system. Very poor, specifically manifested in the low frame rate, image freeze, severe fragmentation, often blurry screen and image incoherence, this non-smooth screen transfer method seriously affects the overall viewing process of the user's viewing process to experience
