Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] figure 1 It is a flowchart of a multi-screen interaction method in an embodiment. Such as figure 1 As shown, the multi-screen interaction method includes the following steps:

[0020] S10: When the mobile terminal receives the media data stream sent by the shared memory of the audio-video terminal, acquire the preset continuous flag bit in each frame of the media data stream received by the mobile terminal.

[0021] When the multi-screen interactive function is enabled, a mobile terminal (preferably a mobile phone) establishes a connection with an audio and video terminal (preferably a se...

Abstract

The invention relates to a multi-screen interaction method and system. When the mobile terminal receives the audio and video terminal media data stream, the present invention presets the continuous flag bit for the acquisition of each frame of the received media data stream, judges whether the current frame and the previous frame are continuous according to the continuous flag bit, and records the number of discontinuities , if the number of discontinuous times reaches the upper limit, the audio and video terminal will be notified, and the audio and video terminal will clear the media data stream in its shared memory and re-store the new media data stream; the mobile terminal will clear the received media data stream and receive it again The new media data stream re-stored by the audio and video terminal clears the previous media data stream through the audio and video terminal and the mobile terminal, so that the mobile terminal does not receive incomplete decoding data, and the speed of storing the data of the audio and video terminal into the shared memory is comparable to that of The speed at which the mobile terminal reads the shared memory data is synchronized, so that the performance after freezing can return to normal, and finally solve the problem of live broadcast or mirror screen freezing for a long time.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-screen interaction method and system. Background technique [0002] In recent years, with the rise of mobile Internet technology, people have deeply felt the convenience brought by mobile Internet technology. Smart mobile terminals represented by smart phones and tablet computers are setting off a fingertip revolution sweeping the world, and the development of mobile Internet is unstoppable. At the same time, with the development of triple play and the improvement of mobile bandwidth transmission rate, the multi-screen interactive technology built on the home LAN has developed rapidly. [0003] At present, most multi-screen interactive applications are implemented through the DLNA protocol. Through the construction of the DLNA protocol, the mobile terminal can watch the media data stream of the audio and video terminal (set-top box, smart TV, etc.) through the wireless ...
