Media multi-type switching carousel system and method

The present invention relates to a playback system and method, and more particularly to a media multi-type switching carousel system and method.

There are a variety of players currently in use on the market, but existing players can only play certain forms of audio and video format documents. If you need to play a document in another format, you must use a special tool to convert the format first. The entire format conversion process requires not only the necessary hardware resources, but also a long time.

In addition, some units not only require the playback of documents in audio and video formats, but also require the transmission of Powerpoint format documents, Flash format documents and image format documents, etc. Currently, the existing players cannot meet such complicated requirements, if the playback document format is After the conversion and then playing, there is no guarantee that some time-sensitive programs will play instantly.

In view of the above, it is necessary to provide a media multi-type switching carousel system and method, which can meet the requirements of playing a plurality of formats of documents, and can ensure timely playback of time-sensitive programs.

A media multi-type switching carousel system includes a database server storing a plurality of program documents, a client computer and an application server connected to the database server, and at least one display connected to the application server. The client computer is configured to receive a program play schedule set by a user, where the program play schedule includes a program document selected from a database server, attribute parameters set for each program document, and the program play The start time and end time of the schedule. The application server includes: an exporting module, configured to export and store the program document in the program playing schedule from the database server according to the program playing schedule set by the user received in the user computer to the application server. a recognition module for identifying a type of each program document by parsing an overall structure of each program document in the program play schedule; and a control acquisition module for each program in the program play schedule The playing of the document is obtained from the application server, and the playing module is configured to play the corresponding program document according to the obtained playing control, and display the played program on the display.

A media multi-type switching carousel method includes the following steps: (a) providing a client computer for receiving a program play schedule set by a user, the program play schedule including a program document selected from a database server, The attribute parameters set for each program document and the start play time and end play time of the program play schedule; (b) export the program files in the program play schedule from the database server according to the program play schedule and Storing to an application server; (c) identifying the type of each program document by parsing the overall structure of each program document in the program play schedule; (d) playing each program document in the program play schedule Starting to obtain a play control of a type to which the program document belongs from the application server; and (e) playing a corresponding program document according to the acquired play control, and displaying the played program on at least one display.

Compared with the prior art, the media multi-type switching carousel system and method realize the requirement of playing a plurality of format documents, which can automatically acquire relevant information of the program document and select and match each program before starting to play. The program control matches the play control, and then loads the selected play control to play the corresponding program, so that the time-sensitive program can be played instantly.
