Embodiment Construction

[0073] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0074] First, the networking environment of the present invention is described:

[0075] Multiple target multimedia devices are connected to the same internal network. The internal network can be a LAN in a home or office, or a directly connected internal network without any configuration. The switches in the network support the Internet Group Management Protocol (IGMP, Internet Group Management Protocol) protocol.

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...
