Automatic clear, adding recording and searching acquiring method for digital TV EPG information

Abstract

A method for automatically clearing, increasing record and seeking for obtaining of EPG information of digital TV includes four processes of automatically clearing EPG information record, increasing EPG information record, increasing EPG current / next information record and seeking for obtaining EPG information record. Its automatically clearing process includes confirming recording space and maximum recording number, setting reserving time of EPG information to avoid overflow by long time of operation, indexing out newest record time when record number is less than zero, calculating out threshold time, deleting off record exceeding threshold and refreshing information record.

Description

technical field [0001] The invention belongs to the technical field of digital televisions, and more specifically relates to the design of methods for automatically clearing, adding records, searching and obtaining EPG information of digital televisions. Background technique [0002] Among digital TV receiving terminal products, Electronic Program Guide (EPG) is a function closely related to consumers. Through the electronic program guide, consumers can learn about the future broadcasting status of each channel's programs, make program reservations, read plot briefs, obtain various information about digital media, and so on. [0003] The traditional methods of automatic deletion, adding records and searching and obtaining EPG information have no automatic maintenance function, cannot prevent data overflow, and are not stable enough. At the same time, its information storage and retrieval speed is slow, and the call interface is also troublesome, wh...
