System and method for dynamic control of downloading multiple videos
A system for adaptive control of the download of multiple videos includes at least one electronic device, a client coupled to the at least one electronic device, and a displaying device coupled to the client. The electronic device includes a video content divided into a plurality of video chunks. The client downloads each video chunk according to a bandwidth change trend and a displaying of an aspect ratio that is displayed on the displaying device and adjusts instant bandwidth change trend in downloading each video chunk. A method for such adaptive downloading control is also provided.
1. A system for dynamic control of downloading multiple videos comprising:
at least one electronic device comprising a video content comprising a plurality of video chunks;
a client coupled to the at least one electronic device; and
a displaying device coupled to the client and configured to display the video content;
wherein the client is configured to:
download each video chunk in a decreasing order of an aspect ratio and in an ascending order of a bandwidth change trend;
sort the plurality of video chunks into an instant buffer insufficiency area and an instant buffer adequacy area, and a plurality of video chunks in the instant buffer insufficiency area is downloaded before a plurality of video chunks in instant buffer adequacy area is downloaded; and
adjust an instant bandwidth change trend of downloading each video chunk.
2. The system of claim 1 , wherein the plurality of video chunks in the instant buffer insufficiency area is downloaded by the client according to the decreasing order of the display of an aspect ratio and an ascending order of the instant bandwidth change trend, and the plurality of video chunks in the instant buffer adequacy area is downloaded by the client according to the ascending order of the instant bandwidth change trend.
3. The system of claim 1 , wherein the bandwidth change trend comprising a maximum value of the bandwidth change trend and a minimum value of the bandwidth change trend, when an instant bandwidth change trend of downloading the plurality of video chunks is greater than the maximum value of the bandwidth change trend or less than the minimum value of the bandwidth change trend, the client is configured to adjust the instant bandwidth change trend to be located between the minimum value of the bandwidth change trend and the maximum value of the bandwidth change trend.
4. The system of claim 1 , wherein the at least one electronic device is a server or a personal computer.
5. A method for dynamic control of downloading multiple videos, comprising:
(a) dividing a video content into a plurality of video chunks,
(b) downloading each video chunk in a decreasing order of an aspect ratio and in an ascending order of a bandwidth change trend, sorting the plurality of video chunks into an instant buffer insufficiency area and an instant buffer adequacy area, and downloading a plurality of video chunks in the instant buffer insufficiency area, before downloading a plurality of video chunks in instant buffer adequacy area;
(c) adjusting an instant bandwidth change trend of downloading each video chunk; and
(d) displaying the video content.
6. The method of claim 5 , wherein the step (b) comprises following step b2: downloading the plurality of video chunks in the instant buffer insufficiency area according to the decreasing order of the display of an aspect ratio and an ascending order of the instant bandwidth change trend, and downloading the plurality of video chunks in the instant buffer adequacy area according to the ascending order of the instant bandwidth change trend.
7. The method of claim 5 , wherein the bandwidth change trend comprising a maximum value of the bandwidth change trend and a minimum value of the bandwidth change trend, when an instant bandwidth change trend of downloading the plurality of video chunks is greater than the maximum value of the bandwidth change trend or less than the minimum value of the bandwidth change trend, adjusting the instant bandwidth change trend to be located between the minimum value of the bandwidth change trend and the maximum value of the bandwidth change trend.
