Embodiment Construction

[0055] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0056] see figure 1 , is a flowchart of a method for synchronously playing videos on different devices according to an embodiment of the present invention. The method comprises the steps of:

[0057] First enter step S101, the master device obtains the first video stream from the server, and sends the video stream identifier corresponding to the first video stream to one or more slave devices.

[0058] The master device and each slave device are electronic devices with data transmission functions and video playback functions, such as mobile phones, tablet computers, personal computers, digital set-top boxes, and the like. The video stream identifier is a physical quantity representing the difference between the currently playing vid...

Abstract

The invention provides a method and system for realizing synchronous video playing of different devices. The system comprises a master device, slave devices and a server, the master device calculatescommunication delay information with at least one slave device, and sends an identifier of a video stream obtained from the server, the calculated communication delay information, a first playing timestamp of the currently played video stream or the playing timestamp of the nth frame of video stream to the corresponding slave device. Each slave device generates a second playing timestamp according to the corresponding communication delay information and the first playing timestamp of the currently played video stream, or generates the second playing timestamp according to the communication delay information and the playing timestamp of the nth frame of video stream, and starts to playing a second video stream from the second playing timestamp. Therefore, the synchronous operation of playing the video stream by the master device and the slave device is achieved, the requirements of simultaneously watching the video stream on different devices of users is met, and the user experience isimproved.

Description

technical field [0001] The invention relates to the field of video playback, in particular to a method and system for realizing synchronous video playback by different devices. Background technique [0002] Video stream data generally includes audio data and video data. During the playback of a video stream, the audio data and video data of the same video stream are often out of sync. In order to ensure that the audio data and video data are played at the same pace, the audio data and video data need to be synchronized. Audio and video data synchronization refers to synchronization by selecting a unified reference clock (such as audio PTS, video PTS or external system clock). The general audio and video synchronization methods are as follows: (1) synchronous video to audio; (2) Synchronize audio to video; (3) Synchronize audio and video to an external clock. However, the above-mentioned several synchronization methods are aimed at the situation where the audio and video of...
