Embodiment 1

[0035] Embodiment 1 of the present application provides a data transmission method, which is applied to electronic equipment and can solve the above figure 1 The problem of low download efficiency in the download process shown, of course, the data transmission method described in Embodiment 1 of this application is not limited to solving figure 1 The problems existing in the downloading process shown are only illustrative illustrations for the convenience of understanding.

[0036] In order to facilitate understanding, the application scenario of the data transmission method provided by the first embodiment of the present application is described, refer to figure 2 as shown, figure 2 It is a schematic diagram of a scenario of a data transmission method provided in Embodiment 1 of the present application. figure 2 The scene shown includes an electronic device 201 and a cloud 202; the electronic device 201 may be a device that executes the data transmission method provided ...

Embodiment 2

[0068] Based on the data transmission method described in Embodiment 1 above, Embodiment 2 of the present application provides a data transmission method, and details the downloading of index information in the data transmission method described in Embodiment 1. In this embodiment, the index information The m3u8 file may be included. Of course, this embodiment is only an exemplary description, and does not mean that the application is limited thereto. refer to Figure 4 As shown, the method includes the following steps:

[0069] Step 401, start an automatic update thread.

[0070] Step 402, downloading index information through an automatic update thread.

[0071] In this embodiment, the index information may be an m3u8 index file. The downloading of index information may be triggered by a trigger operation, or may be triggered by a thread request for downloading multimedia slice data. Refer to the description of obtaining trigger information in Embodiment 1, which will not...

Embodiment 3

[0083] Based on the data transmission method described in Embodiment 1 above, Embodiment 3 of the present application provides a data transmission method, and details the downloading of multimedia slice data in the data transmission method described in Embodiment 1. In this embodiment, multimedia Slice data includes video slice data, which can also be called video transport stream (English: Transport Stream, TS), that is, video TS. , divided into several seconds of video slice data, usually including audio tracks and video tracks, of course, this embodiment is just an example, and does not mean that the application is limited thereto. refer to Figure 5 As shown, the method includes the following steps:

[0084] Step 501, judging whether the cached index data contains address information of multimedia slice data.

[0085] If the judgment result is that the index data contains the address information of the multimedia slice data, execute step 502 ; if the judgment result is t...

Abstract

The embodiment of the invention provides a data transmission method, a device, electronic equipment and a computer storage medium. The method comprises the following steps: obtaining triggering information, downloading index information according to the triggering information, and enabling the index information to comprise at least one part of address information corresponding to at least one part of multimedia slice data; and downloading at least one part of corresponding multimedia slice data according to the at least one part of address information, and when the target multimedia slice data is downloaded, downloading the address information of other multimedia slice data except the target multimedia slice data in the index information in parallel. Since the index information and the multimedia slice data are downloaded in parallel, downloading of the multimedia slice data is not affected by downloading the index information, downloading efficiency of the index information and the multimedia slice data is improved, and playing fluency of the multimedia slice data is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of electronic information technology, and in particular, to a data transmission method, device, electronic equipment, and computer storage medium. Background technique [0002] In the field of electronic information technology, multimedia data, such as video, image, audio and other data forms, are more and more widely used for information transmission. The data transmission volume of multimedia data is also increasing, and users have higher and higher requirements for data transmission rate. [0003] For example, when a user uses a browser to watch a multimedia file, the terminal device downloads the multimedia data from the server, and then plays it for the user. However, many factors will affect the downloading of multimedia data, resulting in slow downloading speed, seriously affecting the transmission rate of multimedia data, and also reducing the fluency of playing multimedia files. ...
