Multimedia program scheduling method and device

Abstract

The embodiment of the invention provides a multimedia program scheduling method and device. The method comprises the steps of: acquiring a playing schedule of each playing partition according to a playing plan, and respectively starting periodic planning scheduling for each playing partition; carrying out clock synchronization with a central clock source, and according to preset scheduling momentpoints, acquiring the playing schedule, all playing lists and multimedia files of the current playing partition; calculating an offset between the preset scheduling moment points of each multimedia file and a planed playing moment point, carrying out played frame offset calculation on the multimedia files with the offsets and generating detailed playing data; and periodically starting a schedulingmethod, generating detailed scheduling result data, and by a player terminal, carrying out multimedia playing according to the detailed scheduling result data. According to the embodiment of the invention, by acquiring the offsets of the playing data of the playing partitions and carrying out synchronization correction according to the offsets of the playing data, the playing progress of each playing partition of a plurality of terminals is guaranteed to be kept consistent, and consistency of multimedia program playing is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of playing digital media information, and in particular to a multimedia program scheduling method and device. Background technique [0002] With the rapid development of network technology and information technology, digital media technology has applications in all aspects of life. Traditional print advertisements, print media, and guide signs are all developing towards digital display. Behind these applications, there are corresponding digital The media information release system is used as support. Taking the Passenger Information System (hereinafter referred to as PIS) as an example, it deploys a media editing and publishing system in the center of the line, which is responsible for the layout production of each terminal device in the line, the compilation of broadcast plans, and the editing and publishing of other passenger information. Play plan data and multimedia files are r...

Problems solved by technology

[0003] However, in the process of sending multimedia programs to each playback terminal for combined playback, the existing program scheduling method only schedules at the program switching time point. Due to the differences in the clock crystal oscillators of each playback terminal, there will be problems in the program playback process. A small amount of deviation will eventually lead to the out-of-sync phenomenon of audio and video information on multiple playback terminals within a period of time
