Embodiment 1

[0028] In order to solve the problem that the terminal download rate strategy is not described in the existing protocol, causing the terminal to excessively occupy broadband resources during the process of downloading the corresponding film source, which is not conducive to the normal use of other users in the same network environment, the present invention implements The example provides a download control method.

[0029] See figure 2 , the download control method includes the following steps:

[0030] S21: Obtain the real-time download rate during the process of downloading the fragment source of the current code rate.

[0031] In this embodiment, the download rate is the average download rate in the time period from the start of downloading of the segment source to the current moment. For example, the terminal is currently downloading the slice source X1, and the download starts at t1=0, assuming that the current download rate is obtained at the time t2=1ms, at this tim...

Embodiment 2

[0067] On the basis of the first embodiment, the embodiment of the present invention provides a download control method, which is described in combination with specific examples, so as to better understand the present invention.

[0068] See image 3 , the download control method provided by this embodiment includes the following steps:

[0069] S301: Download a fragment source with a code rate of VL.

[0070] In this embodiment, the webcast is taken as an example. It is assumed that the webcast has source files of three bit rates: VL (low bit rate), VM (medium bit rate), and VH (high bit rate). mobile phone, Internet TV, etc.) start watching, that is, the start-up stage, you can choose any bit rate fragmentation source to download, or download according to the preset bit rate, such as the system default bit rate or The code rate manually set by the user is not limited in this embodiment. In this embodiment, it is assumed that the fragment source of the low bit rate VL is d...

Embodiment 3

[0100] An embodiment of the present invention provides a download control device, which is used to implement the steps of the download control method described in Embodiment 1 and / or Embodiment 2 above.

[0101] See Figure 4 , the download control device 40 provided in this embodiment includes an acquisition module 41 , a comparison module 42 and a processing module 43 . Wherein the acquisition module 41 is used for obtaining the real-time download rate during the process of downloading the slice source of the current code rate, and the download rate is the average download rate in the time period from the download of the slice source to the current moment.

[0102] The acquiring module 41 can obtain the download rate of the slice source by dividing the currently downloaded capacity of the slice source by the time from the downloading of the slice source to the current moment. It should be understood that the obtaining module 41 can specifically obtain the capacity of the cu...

Abstract

Embodiments of the present invention provide a download control method, device, multimedia terminal, and computer storage medium. During the process of downloading a slice source of the current code rate, a real-time download rate is obtained; the download rate is from the slice source. The average download rate during the period of downloading to the current moment; compare the download rate with the download rate limit threshold corresponding to the current code rate, the download rate limit threshold is greater than the smooth playback rate of the fragment source, and the smooth playback rate is The minimum download rate for smoothly playing the fragment source; when the comparison result is greater than the download rate limit threshold, the download is suspended until the download rate is less than or equal to the download rate limit threshold and the download is restarted; through the set download rate limit Speed ​​threshold, which can well limit the download rate of the terminal to download the fragment source. The download rate is not too high, but is close to or equal to the download rate threshold, so as to solve the problem of excessive occupation of broadband resources.

Description

technical field [0001] The present invention relates to the technical field of audio and video playback, in particular to a download control method, device and multimedia terminal. Background technique [0002] With the rapid development of the mobile Internet, the promotion of OTT (Over The Top, OTT refers to the development of various video and data services based on the open Internet by Internet companies over the operators) technology and the emergence of various smart terminal devices, such as through Watching videos online on video terminals such as mobile phones, handheld computers, and set-top boxes has become an increasingly common leisure and entertainment method for people. At present, mainstream OTT services are implemented based on HLS (HTTP Live Streaming, Apple's dynamic bit rate adaptive technology), DASH (Dynamic Adaptive Streaming over HTTP) or HSS (HTTP Smooth Streaming) protocols. The common point of these protocols is to encode the source into multiple ...
