Abstract

An remote controller for quick access digital TV program comprises a microprocessor, a keyboard sweeping circuit, an infrared transmission circuit and an EEPROM reading and writing circuit. According to the habits of different household, CPU accumulates watching time and arranges them according to a descending order. When turn off the TV by pressing down POWER, save the TV channel to be watched next time is stored in EEPROM; press down POWER key to turn on the TV, read out the TV channel from the EEPROM and put into the ring structure. With the particular FORECAST key, you can quickly find out available channel so as to save time and prolong remote control and TV set service life.

Description

A kind of remote controller that is used for the fast selecting digital television program

Technical field

The utility model relates to a kind of remote controller that is used for the fast selecting digital television program.More particularly, relate to a kind of analysis user watching habit automatically, the channel that storage may be watched is so that the digital television remote controller of fast selecting TV programme.

Background technology

In existing TV tech, the user watches that digital television program usually wants the multi-pass operation remote controller, if forget the channel at institute favor program place, pass through the long period just can switch to and want the channel seen.If require the user to remember channel, can increase user's use difficulty and workload, in the digital television program system that provides tens covers covers up to a hundred, the user uses very inconvenient especially.Simultaneously, switching digital TV channel continually repeatedly, the useful life that can reduce television set and remote controller.

Because the influence of subjective factors such as the personality of certain household integral, hobby, the digital television program that one family is watched have several channels of relatively concentrating usually.Therefore can in remote controller, write down the digital TV channel of having watched, pass through intellectual analysis then, automatically find out several channels that this family might watch, and be stored in the remote controller, make this domestic consumer can be transferred to these digital TV channels fast afterwards.

Summary of the invention

The utility model provides a kind of remote controller that is used for the fast selecting digital television program, this remote controller can write down and analyze several channels that family often watches automatically, stored then, the user can be transferred to this several channels fast by " FORECAST " button on the remote controller, transfers the platform time thereby save.And the possible digital TV channel number of user can be carried out close friend's setting by " SET " key.This device not only prolongs the useful life of television set and remote controller, and gives the user selecting to provide great convenience aspect the digital TV channel, makes the user save the time that much is wasted in the channel selection process.

The technical scheme that its technical problem that solves the utility model adopts is: pressing " POWER " when key is turned on television set, by the EEPROM read/write circuit, read the digital TV channel that may watch from EEPROM, be put among the loop configuration.Remote controller CPU at first obtains the channel of program key and chooses after the information, this information is noted, and the channel of each program key that adds up is chosen number of times and changed blanking time between the platform; The channel that adds up is chosen number of times and channel viewing time, and carries out descending according to viewing time, and is kept among the RAM.When pressing " POWER " key closing television machine, by the EEPROM read/write circuit, the digital TV channel that may watch (being the longest several channels of viewing time) is docile and obedient preface and is deposited among the EEPROM.The basis of fast selecting digital television program and key are to analyze the channel that this family may watch once more, and store these channel, by calculating the number of times of watching of each channel in nearest one section setting-up time, perhaps calculate total duration of watching of interior each channel of nearest one section setting-up time, according to the queuing algorithm descending, choose the most forward setting number channel, promptly think the digital TV channel that this family may watch once more.Certainly, the user also can use all the other buttons to carry out conventional straighforward operation as usual.

The beneficial effects of the utility model are according to user watched custom, to dope automatically and change the channel that platform may be watched next time, so can save the time of blindly changing platform; Do not need the user to remember channel yet, alleviated user's workload; Reduce simultaneously the channel switching times of pressing number of times and television set of remote controller effectively, prolonged the useful life of remote controller and television set.This device can be stored channel commonly used according to the watching habit of different home automatically, and is easy to operate, wide accommodation.

Embodiment

In Fig. 1, the utlity model has shell and keyboard, with respect to common remote controller, the utility model has increased " FORECAST ", " SET " two buttons, " FORECAST " key helps the user to select the digital TV channel that may watch, and concrete using method is: press " FORECAST " key, the increasing progressively of the digital TV channel that realization may be watched, when arriving greatest measure, get back to the initial value of the digital TV channel that may watch again." SET " key is realized the setting of the loop configuration degree of depth, just the user realizes the setting of the digital TV channel number that may watch by this key, concrete using method is: at first press " SET " key, then by twice numerical key, it is the loop configuration degree of depth, for example the user wishes that the digital TV channel that may watch is 6, so after pressing " SET " key, then by " 0 " key and " 6 " key.In the utility model, the loop configuration degree of depth can be set to 1-99, and general recommendations is set to 2-16.

In Fig. 2, circuit of the present utility model comprises microprocessor CPU, oscillating circuit, keyboard scan, infrared emission, EEPROM.Microprocessor CPU is 8TC89C51RC, the alignment of keyboard matrix circuit links to each other with the I/O interface P0 of microprocessor, line links to each other with I/O interface P1, and signal source of clock directly links to each other with microprocessor, and infrared transmitter links to each other with certain I/O of the interface P2 of microprocessor; The signal source of clock of clock oscillation circuit is made up of capacitor C 1, C2, crystal oscillator Y1; Infrared transmitter is made up of triode Q1, infrared transmitting tube D1, resistance R 1 and battery BT1, the base stage of triode Q1 links to each other with microprocessor by resistance R 1, the collector electrode of triode Q1 links to each other with the negative pole of infrared transmitting tube D1, and the positive pole of infrared transmitting tube D1 is connected back ground connection with battery BT1.

In Fig. 3, the EEPROM read/write circuit is by eeprom chip AT24C02, capacitor C 3, C4, resistance R 2, R3, and the 3.3V power supply forms, resistance R 2, R3 realize SCL, SDA on draw, wherein SCL with connect the 3.3V power supply after R2 is connected, SDA with connect the 3.3V power supply after R3 is connected, guarantee the reliability of serial data read-write.
