Layering framework for multimedia synchronous broadcast and control relationship

Abstract

The invention discloses a layering framework for a multimedia synchronous broadcast and control relationship. The framework maps the multimedia synchronous broadcast and control relationship as a task, and divides the task into 1-L of sub-tasks on a time axis according to a screen dividing arrangement; the relative broadcasting time of the subtask is appointed in the task, the subtask is seriallyplayed in the task; the subtask uses a split screen template or a split screen area to control the display position of broadcasting the content of the multimedia in parallel, each split screen template consists of 1-N split screen areas, each split screen area can bind 1-M of multimedia contents, the relative broadcasting time of the multimedia contents is controlled by broadcasting items; the subtask can be used repeatedly between tasks, the split screen template can be used repeatedly between subtasks; the layering framework for the multimedia synchronous broadcast and the control relationship can lead the elements in the multimedia synchronous broadcast and control relationship to be flexibly used repeatedly; and the broadcast and control relationship has no relation with the specific broadcast and control language.

Description

technical field [0001] The invention relates to the technical field of multimedia synchronous broadcast control, in particular to a hierarchical structure of multimedia synchronous broadcast control relationships. Background technique [0002] With the continuous improvement of the processing capability of playback terminals, it becomes a reality to play multiple multimedia contents simultaneously on one playback terminal. For example, with the help of the "picture-in-picture" technology display mode, one multimedia content can be played in one display area, and other multimedia content can be played in another display area. This way of split-screen playback can get better information. Spread effect, and successfully applied to the field of multimedia advertising. The multimedia synchronous broadcast control technology is the key to split-screen playback, and it is also a research hotspot now. [0003] The current version of SMIL (Synchronized Multimedia Integration Langua...

AI Technical Summary

Problems solved by technology

[0005] Due to the lack of a unified hierarchical structure to describe the multimedia synchronous broadcast control relationship, the existing technology cannot realize the separation of the multimedia synchronous playback control relationship and the playback control file

This has led to the inability to reuse the elements of the multimedia synchronous playback and control relationship in the prior art; at the same time, in the face of playback terminals that support different playback control files, the prior art does not have the function of "make once, play anywhere"
