AI Technical Summary

Problems solved by technology

In the original implementation of the Android system, T is 33.3 ms, so the process takes a maximum of 33.3 ms, which will significantly increase the frame delay and affect the user experience
However, if the cycle T is simply reduced, it will take up too much CPU time and affect performance.

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0040] Such as figure 1 Shown, display frame processing method in the Android WifiDisplay of the present invention comprises the following steps:

[0041] S1: The source device starts processing the display frame;

[0042] S2: The frame composition module puts the display frame in the remote display frame buffer queue;

[0043] S3: The remote display processing thread reads the display frame from the remote display frame buffer queue, puts it into the frame shared object, and sends a frame ready message to the frame transfer thread;

[0044] S4: The frame transfer thread receives the frame ready message, reads the display frame from the frame shared object, and starts to process the display frame. After the frame transfer thread processes the display frame, it sends it to the encoding module for encoding;

[0045] S5: The encoding module en...

Abstract

The invention provides a display frame processing method and system in Android WifiDisplay, belonging to the field of display frame processing. The display frame processing method of the present invention includes the following steps: the frame synthesis module puts the display frame in the remote display frame buffer queue; the remote display processing thread reads the display frame, puts it into the frame sharing object, and sends a frame ready message to the frame relay thread; the frame transfer thread receives the frame ready message, reads the display frame from the frame shared object, starts to process the display frame, and then sends it to the encoding module for encoding; the encoding module encodes the display frame, and the encoded display frame is delivered to the package Sending process; package the sending process to package and send to the remote display device. By changing the interaction mode between the remote display processing thread and the frame transfer thread, the present invention effectively improves the delay phenomenon that occurs when the source device and the remote display device transmit display data, and improves user experience.

Description

technical field [0001] The present invention relates to the field of display frame processing, in particular to a display frame processing method and system in Android WifiDisplay. Background technique [0002] The rapid popularization of smart terminal devices represented by smartphones and tablet computers has brought great convenience to people's lives. While enjoying the good experience brought by the diversification of smart terminal devices, consumers also have a demand for display content sharing among different devices. Between different display terminals, multimedia content is transmitted through the WiFi network to realize the multi-screen interactive technology of sharing display content on different platform devices, which greatly meets this demand. [0003] Among the many multi-screen interactive solutions, WifiDisplay (also known as Miracast) is a technology with better results and more manufacturers. It is a point-to-point display content sharing protocol for...
