Problems solved by technology

[0002] The video playback system includes a playback client and a data acquisition device. The acquisition method of the data acquisition device in the prior art is that the playback client passively receives all data sent by the data acquisition device. This method will cause data playback and download rates to be inconsistent. Thereby causing some problems, for example, when the playback client stops playing and no longer requests data from the data acquisition device, the data acquisition device still downloads data continuously. According to this method, a large part of the data downloaded may not be played by the playback client. The required data is still downloaded and stored, which not only occupies network resources and storage resources, but may cause playback crashes, making the surfing experience of the playback client worse, and making these unplayed video data inefficiently Occupy too many storage resources and reduce the utilization of various data resources

Embodiment 1

[0042] Embodiment 1: set to a fixed value, for example, set a specific value aKb as the unit of data volume, when the data volume downloaded by the data acquisition device reaches aKb, then the data acquisition device acquires data according to the playback rate and sends it to the playback client After receiving the data required by the terminal, continue to download data within the range of a fixed data volume aKb to reach a certain level of dynamic balance.

Embodiment 2

[0043] Embodiment 2: Set the fixed amount of data according to the playback rate and the playback time of the downloaded data. Its playback rate of a certain video is nKb / s, and the playback time of the playback volume of the playback client is m seconds, so the fixed amount of data can be set to m*nkb, and then the data acquisition device acquires data according to the playback rate so that the data acquired by the data acquisition device reaches a certain dynamic balance level within the range of the fixed data amount m*nkb.

Embodiment 3

[0044] Embodiment 3: The fixed data volume is set according to the network condition. When the network condition is good, a smaller fixed data volume is set, and when the network condition is not good, a larger fixed data volume is set. The network bandwidth of a playback client is small and the network speed is slow and unstable. At this time, in order to ensure that the client plays the video smoothly, a large fixed data volume is set. It is assumed that the playback data volume is 2.5M or 3 minutes, and then the data The acquisition device acquires data according to the playback rate so that the data acquired by the data acquisition device reaches a certain dynamic balance level within the range of a fixed data volume of 2.5M or a playback data volume of 3 minutes. And when the network bandwidth of a certain client is large, the network speed is fast and stable, the memory usage of the client is reduced, the resource utilization efficiency of the client is improved, and a sm...

Abstract

The invention provides an obtaining method of data. The obtaining method of the data comprises that a play order sent by a play client side is obtained by a data obtaining device; the data is downloaded by the data obtaining device according to the play order and a fixed data size is reached; and the data needed by the play client side is sent to the play client side by the data obtaining device according to the play order. According to the obtaining method of the data, the play client side can initiatively obtain the data from the data obtaining device according to requirements of the data client side and the data size downloaded is limited in a certain range so that the problem of stored data redundancy caused by unlimited downloading of the data by the data obtaining device is solved and the phenomena of corruption of the play client side are reduced.
