Problems solved by technology

[0003] In the past, program information was generally stored in EEPROM. Due to the limitation of the size of EEPROM, the ability to store information is relatively limited. With the development of digital TV, the number of programs has increased dramatically. If stored in the traditional way, the capacity of EEPROM must be expanded, so that Increase the cost of the product; and the speed of data storage and query depends on the read and write speed of EEPROM, which is also a big bottleneck

Abstract

The invention discloses a method for memorizing and managing program information used in multi-media equipment, and the application of the multi-media equipment memorizes and manages program information through an embedded database. The method using the database to memorize and manage program information, is not subject to restrictions of the storage capacity and the read-write speed, has strong expansibility, and is convenient for maintenance; and in case of a sharp increase of programs, no change of hardware is needed to achieve expansion, and the capability of the equipment is not affected. The invention, combined with the method for memorizing and managing program information, further provides another type of multi-media equipment to which the method is applied, particularly TV and set-top box equipment.

Description

technical field [0001] The invention belongs to the technical field of multimedia equipment, specifically relates to the field of televisions and set-top boxes, and relates to a method for storing and managing program information of televisions or set-top boxes. Background technique [0002] In the design of digital high-definition televisions or set-top boxes, program management is a very important aspect, mainly including two parts: one is the extraction of program information, mainly by extracting PAT table (Program Association Table, program association table) and PMT (Program Map Table, program mapping table) information in the table to obtain information such as ServiceID and AudioID related to the program, as well as the manufacturer providing these programs; the second is how to store the information after the program information is extracted, and in a reasonable way , It is very convenient to provide consumers with browsing, editing and classification, that is, the ...
