Problems solved by technology

[0004] The above method 1 needs to frequently extract data from the storage device to the cache area during the data playback process. Therefore, this method has the problems of time-consuming and inconvenient, especially when the data is not extracted in time, it will also cause the playback to freeze The problem
Although the above-mentioned method 2 can avoid the problem of frequently extracting data, the size or duration of the data to be played back is usually uncertain. When , there are also time-consuming and inconvenient problems, and this method also has the problem of occupying too much cache resources
[0005] It can be seen that the existing data playback method has the problem that the data cannot be played back quickly and conveniently.

Abstract

The invention discloses a data playback method, and the method comprises the steps: obtaining first playback data, the first playback data comprising data of a data block in a data block set, the data block set comprising a plurality of data blocks arranged according to a time sequence, and the plurality of data blocks being obtained by splitting data to be played back; in the process of playback of the first playback data, loading buffer data to a buffer region, wherein the buffer data comprises at least one data block arranged behind the first data block corresponding to the first playback data in the data block set; and playing back the data to be played back according to the first playback data and the buffer data. According to the method, the to-be-played-back data can be played back quickly and conveniently.

Description

technical field [0001] The present disclosure relates to the technical field of data playback, and more specifically, to a data playback method, device, and terminal equipment. Background technique [0002] With the continuous development of computer technology, the application of data playback technology in different fields of people's life can bring great convenience to people's life. For example, in the field of rail transit, by collecting the track information data of the train on the running route and playing back the track information data, the train can be better monitored to improve the safety of the train and facilitate people's lives. [0003] At present, the following two data playback methods are usually used to play back the data to be played back: Method 1. First, store the data to be played back in the storage device, and then extract the data of a fixed duration from the storage device at each moment for playback, that is , realize the playback processing of...
