Multimedia data synchronized playing method, device and system

Abstract

The invention discloses a multimedia data synchronized playing method, a multimedia data synchronized playing device and a multimedia data synchronized playing system. The method comprises the steps of when a request of adding first slave equipment into a multimedia playing group is acquired, sending a control command to at least one piece of second slave equipment included in the multimedia playing group for controlling the all second slave equipment to clear original cache data and controlling to feed back current playing progress information; determining to add the first slave equipment into the multimedia playing group according to the request; and sending corresponding multimedia data to the multimedia playing group including the first slave equipment, thus allowing the multimedia playing group to play synchronously. According to the method, device and system of provided by the invention, only clearing of the original cache data of the existing equipment is needed when the new equipment is added, and then the corresponding multimedia data is sent according to the current playing progress information, so that the existing all equipment is not interrupted is ensured when the new equipment is added to follow the playing, and thus synchronized playing is achieved, and playing continuity and playing effect are improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method, device and system for synchronously playing multimedia data. Background technique [0002] As a kind of smart home, the intelligent multimedia system is often composed of multiple intelligent multimedia devices, also known as a multimedia playback group. These smart multimedia devices can be controlled to perform certain operations through network synchronization, such as playing a certain song synchronously. If the media data transmission of each device is regarded as a media stream, then the synchronous playback between multiple devices can be understood as Synchronization between streams. In the use of multimedia play groups, it is often necessary to edit the play group during play, which involves how to add another device to follow the play during the process of one or more synchronous play. [0003] The general practice of existing solutions is ...
