Method and server for synchronous playing and player

Abstract

The invention discloses a method and a server for synchronous playing and a player. The method comprises the following steps: from a plurality of target multimedia apparatuses, a random apparatus is picked as a master control apparatus and the total number of the target multimedia apparatuses is configured on the master control apparatus; a player of each apparatus is connected to a synchronous playing server on the master control apparatus and sends a playing starting request message to the synchronous playing server upon a successful connection; and when the synchronous playing server receives the playing starting request messages from all the players, the synchronous playing server determines a current playing time curPlayTime according to a current playing system clock curSysTick maintained by itself and sends playing starting clock messages, carrying the curPlayTime, to all the players, which receive the playing starting clock messages and start to play multimedia files synchronously according to the curPlayTime in the messages. The method improves the precision of multi-player synchronous playing.

Description

technical field [0001] The invention relates to the technical field of multimedia playing, in particular to a synchronous playing method, a server and a player. Background technique [0002] All existing embedded multimedia devices provide media players, and the core of the player is the audio and video (A / V) synchronization engine. V) The interactive control and clock control of multi-player synchronous playback are added to the synchronous control. [0003] The existing multi-player synchronous media playback technology has the following defects: [0004] 1. The audio and video (A / V) synchronization engine of the player in the embedded multimedia device mostly uses the system clock of the local device, and the system clock on each device may be different. Therefore, the consistency of the player clock of multiple devices cannot be guaranteed , there is no guarantee that multiple players will play synchronously and accurately. [0005] 2. When multiple device players are...

AI Technical Summary

Problems solved by technology

[0004] 1. The audio and video (A / V) synchronization engine of the player in the embedded multimedia device mostly uses the system clock of the local device, and the system clock on each device may be different. Therefore, the consistency of the player clock of multiple devices cannot be guaranteed , there is no guarantee that multiple players will play synchronously and accurately

[0005] 2. When multiple device players are playing, operate the player of one of the devices, and the players of other devices cannot respond synchronously without external hardware control devices. Therefore, the operation cannot guarantee synchronization
