Method and device for rapidly processing and displaying electronic program guide information, digital television and main board of digital television

Abstract

The invention relates to a method and device for rapidly processing and displaying electronic program guide information, a digital television and a main board of the digital television. The method comprises the steps of after the digital television is powered on and started up, writing event information constantly obtained through filtration and analysis in a transport stream (TS) code stream in a USB storage which is arranged inside the digital television and electrically connected with a main IC; under the condition that the digital television is started up, updating the event information in the USB storage in a real-time mode, and detecting and deleting the passed event information in the USB storage in a timed mode; when an electronic program guide menu is opened, reading the event information after the current time from the USB storage so as to construct the electronic program guide menu. Precise double data rate (DDR) space can be completely released and used for processing other tasks, a user can check all the information of all electronic program guides (EPG) without worrying out the problem of incomplete data collection, the circumstance that the EPG information of different frequency point programs is vacant will not be caused, and a brand new method for storing, managing and displaying EPG information is realized.

Description

technical field [0001] The present invention relates to a digital television, and more specifically, to a method and device for fast processing and displaying information of an electronic program guide, a digital television and a main board thereof. Background technique [0002] Electronic Program Guide (Electronic Program Guide, EPG) refers to the service information (Service Information, SI) defined by the DVB standard inserted in the TS (Transport Stream) transport stream conforming to MPEG-2 (13818-1), so that the integrated TV The receiving decoder (IRD) can extract the list and broadcast parameters of the programs broadcast by the program provider from the TS stream, and display them to digital TV users in an intuitive form, so that users can view the information they are interested in, such as: classification by program (such as music programs, sports programs, movies, etc.) Retrieve programs, retrieve programs by program provider, check the program broadcast list in ...
