Embodiment Construction

[0049] As mentioned above, in the various existing playback synchronization methods, there is often a problem of low accuracy, which is difficult to meet user needs.

[0050] In a specific implementation of the prior art, the master player and the slave player are assigned in the multi-device playback system. When the playback progress of the slave player is not synchronized with the master player, the Play progress difference, change the pointer pointing from the playback device data buffer. After the pointer is changed, the pipeline time of the slave playback device is correspondingly changed. For the audio and video data that is about to be written into the data buffer, if its timestamp is less than the changed pipeline time, it will be discarded, so as to achieve fast synchronization with the main playback device; on the contrary, it will be written into the corresponding audio and video buffer area, and then wait for synchronization with the main playback device.

Abstract

A playing synchronization method and device, a storage medium and a user side are disclosed. The method comprises: receiving ideal playing progress information from a server side, the ideal playing progress information being used for indicating a playing progress of a to-be-played file determined by the server side through calculation; determining actual playing progress information, wherein the actual playing progress information is used for indicating a user side to output the playing progress of the to-be-played file; determining a synchronization progress difference value according to theideal playing progress information and the actual playing progress information; and for each data block in the to-be-played file, determining a playing mode of the data blocks according to the synchronization progress difference. According to the invention, a more accurate synchronization target can be provided for each user side, so that the accuracy of each user side can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a playback synchronization method and device, a storage medium, and a user terminal. Background technique [0002] In scenarios such as exhibition halls, outdoor billboards, public transportation, smart home appliances, and car audio and video, multiple devices are often used to play the same multimedia file, and multiple devices display the same picture and play the same sound at the same time. If the synchronization error of the picture and sound is very small, it can bring a more shocking feeling, which is impressive. [0003] However, in the various existing playback synchronization methods, there is often a problem of low accuracy, which makes it difficult to meet user needs. [0004] There is an urgent need for a playback synchronization method that can effectively improve the accuracy of playback synchronization. Contents of the invention [0005] The technic...
