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...
