Abstract

A video processing method applied to a splicing screen is provided, including: dividing each frame of an initial video into multiple sub-images; and forming sub-videos using all the sub-images, the initial video and each sub-video including M frames, M being an integer greater than 1, and durations of individual frames of the sub-videos being the same, wherein i-th frames of all sub-videos are spliced into an i-th frame of the initial video, and a relative position of the i-th frame of any sub-video in the i-th frame of the initial video is the same as a relative position of any other frame of the sub-video in a corresponding frame of the initial video, where i is a variable whose value is a natural number from 1 to M. A dividing task distribution method, a computer-readable storage medium, a scheduling server, an execution server and a video processing system are provided.

First claim

What is claimed is:

1. A dividing task distribution method, comprising:
generating at least one dividing task according to a received source video; and
allocating, according to statuses of a plurality of servers, each dividing task to a server that meets a predetermined condition, so that the server that receives the dividing task executes a video processing method applied to a splicing screen for displays, wherein the video processing method comprises:
dividing each frame of an initial video into a plurality of sub-images, the initial video comprising M frames, where M is a positive integer greater than 1; and
forming a plurality of sub-videos using all of the obtained plurality of sub-images, each sub-video comprising M frames, and durations of individual frames of the plurality of sub-videos being the same as each other, wherein i-th frames of all of the plurality of sub-videos are spliced into an i-th frame of the initial video, and for any one sub-video, a relative position of the i-th frame of the sub-video in the i-th frame of the initial video is the same as a relative position of any other frame of the sub-video in a corresponding frame of the initial video, where i is a variable, a value of which is a natural number from 1 to M, and
the dividing task distribution method further comprises, between the step of generating at least one dividing task according to a received source video and the step of allocating, according to statuses of a plurality of servers, each dividing task to a server that meets a predetermined condition, a step of:
sorting N servers in ascending order by the number of tasks executed by each server; and
the step of allocating, according to statuses of a plurality of servers, each dividing task to a server that meets a predetermined condition comprises:
sequentially sending the generated dividing tasks to servers in the top L among the N servers, where a value of L is the same as the number of the generated dividing tasks, and L<N.

2. The dividing task distribution method of claim 1 , wherein the predetermined condition is that:
a number of tasks executed by the server in the plurality of servers does not exceed a predetermined number.

3. The dividing task distribution method of claim 1 , further comprising:
storing mapping relationship between each dividing task and the server executing the dividing task.

4. A computer-readable storage medium for storing an executable program, wherein when being invoked, the executable program is capable of executing the dividing task distribution method of claim 1 .

5. A scheduling server, comprising:
a second storage module storing a second executable program therein;
one or more second processors that call the second executable program to implement the dividing task distribution method of claim 1 ; and
a second I/O interface coupled between the second processor and the second storage module to implement information interaction between the second processor and the second storage module.

6. A video processing system, comprising the scheduling server of claim 5 .
