Problems solved by technology

In the implementation process, the EPG content is downloaded to the local set-top box through the regular update of the background program, and the EPG content file on the server side is changed in real time, including the file organization method of the EPG content. During this real-time change process, the set-top box every After the first update, the local files and file organization have also changed, so often the EPG content files on the server side and the EPG content files in the set-top box cannot be updated synchronously, resulting in the lack of some latest EPG content in the set-top box or the accumulation of a large number of invalid files

Abstract

The embodiment of the invention discloses a method and device for synchronizing EPG (Electronic Program Guide) server content in an embedded platform. The method comprises the following steps of: transmitting an EPG request to a server; receiving the server EPG content information returned by the server; and comparing the client end EPG content information with the server EPG content information and updating the client end EPG content information and the corresponding catalogue thereof by comparing. The device comprises an information receiving unit, an information comparing unit and an information updating unit. The client end EPG content information is updated, thereby ensuring that the EPG organizing way and EPG content of the server end have no redundant file at the client end, completely maintaining consistency with the EPG content of the server and realizing the synchronous updating of client end and server end EPG contents.

Description

technical field [0001] The invention relates to the communication field, and more specifically, relates to a method and a device for synchronizing EPG server content in an embedded platform. Background technique [0002] Currently, embedded products, especially set-top boxes, can provide users with information on all programs through the electronic program guide (EPG, Electronic Program Guide). , is responsible for the navigation of programs and various services, and users can understand the relevant information of programs (including program time, broadcast time, content summary, etc.) through EPG. In the development of the set-top box, based on the graphical interface of FrameBuffer (frame buffer), the set-top box first downloads all the EPG data from the server to the client through a background program, and the EPG data is described through a unified XML file, and then the GUI program parses the local XML (Extensible Markup Language) file to display EPG information. In...
