System and method for achieving synchronized broadcast and control of media files in multiple intelligent terminals

Abstract

The invention relates to a system and a method for achieving synchronized broadcast and control of media files in multiple intelligent terminals. The system comprises a master control terminal and a plurality of controlled terminals connected with the master control terminal. The master control terminal comprises a digital media service module and a digital media control module, wherein the digital media service module is used for storing the media files needing synchronized broadcast, and the digital media control module is used for controlling the controlled terminals to synchronously broadcast the media files stored in the digital media service module or the selected media files in the controlled terminals. Each controlled terminal comprises a digital media present module for synchronously broadcasting the selected media files under the control of the digital media control module. By means of the system and the method for achieving synchronized broadcast and control of the media files in multiple intelligent terminals, synchronized broadcast in multiple terminals can be achieved without additionally arranging hardware resources based on digital living network alliance (DLDA) interconnection and interworking technical specifications, and synchronous control functions such as pause, stop, relocation, voice regulation and the like can be achieved. Therefore, the system and the method for achieving synchronized broadcast and control of the media files in multiple intelligent terminals are wide in application range.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to the field of synchronous playback control of media files, and specifically refers to a system and method for realizing synchronous playback and control of media files in a multi-smart terminal. Background technique [0002] With the development of network technology and the popularization of smart terminals, people's demand for multimedia services has also increased. For example, in multimedia classroom teaching, home media sharing and other occasions, multiple users will share the same video, music, photo and other media files through different smart terminals at the same time. How to play and control the same video file synchronously, the initial method is to use video splitter or screen splitter to realize the video synchronization of multiple display terminals. The disadvantage of this method is that the terminal needs additional hardware devices, and it is o...

How to play and control the same video file synchronously, the initial method is to use video splitter or screen splitter to realize the video synchronization of multiple display terminals. The disadvantage of this method is that the terminal needs additional hardware devices, and it is only suitable for TV terminal with video input interface, not suitable for tablet PC and mobile phone terminal

Another method is to build a live streaming media server to convert video files into live video streams. Other smart terminals can use players that support streaming media protocols to realize multi-terminal synchronous playback. The disadvantage of this method is that it requires additional Add hardware equipment, and if you need to drag and relocate (seek) to any playback time point during playback, this live broadcast method cannot be realized
