Abstract

The invention discloses a multimedia synchronous play method, device and system, and a terminal. The method comprises the steps of detecting currently cached data volume of a cache space in a process of synchronously playing multimedia data of the cache space; detecting a current data caching rate; and controlling the cached data volume of the cache space to be kept between a second preset threshold value and a third preset threshold value according to the currently cached data volume and the current data caching rate. Cache management is carried out on the media data in a constant current approximate mode, when multiple play devices cache the data, the bandwidth is employed reasonably in balance, the bandwidth occupation will not be increased explosively, the intermittent sudden change fluctuation is avoided, the network pressure is reduced, the synchronism of the cached data is ensured, and synchronous play of the multiple play devices is realized.

Description

technical field [0001] The present invention relates to the technical field of multimedia playback, in particular to a multimedia synchronous playback method, device, terminal and system. Background technique [0002] Multiple playback devices (such as mobile phones, computers, speakers, various players, etc.) are connected through wired or wireless network technology to form a multimedia synchronous playback system, which plays the same audio, video or picture synchronously, and has been widely used. [0003] In the prior art, for multiple playback devices that implement synchronous playback, the buffered media data is generally played during the buffering process. When the amount of cached data in the playback device overflows, close the data cache, so that the data source device immediately stops transmitting media data to the playback device, so that the cache space of the playback device stops caching immediately. When the amount of cached data in the playback device i...
