Set top box program searching method and set top box program searching system

Abstract

The invention discloses a set top box program searching method and a set top box program searching system. The set top box program searching method disclosed by the invention comprises the following steps: receiving or reading the program frequency point information file of external storage equipment and detecting whether the program frequency point information file is effective or not; when the program frequency point information file is effective, analyzing the program frequency point information file and obtaining the data item parameters of the program frequency point information which iscontained in the program frequency point information file; setting the data item parameters to a tuner; locking frequency points according to the data item parameters which are set to the tuner and demodulating; and renewing the data item parameters and storing the data item parameters to a flash memory in a set top box. By means of the modes, on the premise of not changing the existing structureof the set top box, the set top box program searching method and set top box program searching system disclosed by the invention can be used for rapidly realizing the program searching of the set topbox when the resources of the system do not need to be occupied.

Description

technical field [0001] The invention relates to the field of radio and television, in particular to a set-top box program search method and a set-top box program search system. Background technique [0002] With the continuous development and maturity of digital TV technology, users have put forward higher requirements for set-top boxes in terms of functions and performance. At the same time, users have higher and higher pursuit of user-friendly operation of set-top boxes. [0003] TV station search is one of the basic functions of set-top boxes. Traditional TV station search methods include automatic channel search and manual channel search. Automatic channel search is a global search within the receiving range of the tuner according to the preset channel list in the set-top box. The search time is usually In 4 to 8 minutes. At the same time, the automatic channel search is because the channel list is fixed, and the channel list has different standards in different countri...

Problems solved by technology

However, the applicant of the present invention has also found that because this technology needs to store the list in the CPU read-only memory ROM or in the EEPROM, it takes up a certain amount of memory space; meanwhile, the list edited by the user does not have portability, that is, it cannot be stored in the EEPROM. Repeated use in multiple set-top boxes; in addition, when the user upgrades the software or restores the factory settings, the user's channel list will be cleared due to the erasure of the ROM or EEPROM, and the channel list set by the user cannot be saved
