Abstract
The invention discloses a television channel selection method and a remote controller. The television channel selection method comprises the steps of: setting a selection key on the remote controller, defining a review key dual-click mode, when the selection key is pressed down, determining that a watching channel is a key return destination channel, in a process of selecting a program, and when a reviewing key is clicked for two times, returning the key return destination channel. The remote controller comprises a keyboard and a microprocessor, wherein the microprocessor uses the watched channel as the key return destination channel when the selection key is pressed down, and when the reviewing key is clicked for two times, the return destination channel is returned. On the premise of no change of a favorite function of the original return key, the function of the traditional return key of the remote controller is enlarged, so that trouble of multiple times of key pressing even one-to-one channel searching is avoided for a program which is watched by a user when other programs are freely browsed temporarily due to reasons such as advisement and the like only and the former program which is watched by the user is returned by using one key. Great convenience is provided for the user.
Description
Technical field
The present invention relates to television set and make the field, particularly DTV STB, concrete is the remote controller of STB and the remote controller of television set.
Background technology
Television set, video tape recorder, DTV STB etc. all have a remote controller at present; The user operates television set, video tape recorder or STB through remote controller, adjusts etc. and can accomplish through remote controller such as the sound size of selecting program, adjustment broadcast program or to image.
At present, no matter be that the TV remote controller or the general structure of the remote controller of digital TV set box remote control or video tape recorder are: mainly form by the microprocessor chip that forms remote signal, crystal oscillator, amplifier transistor, infrarede emitting diode and keyboard matrix.Its operation principle is following: the oscillator of microprocessor chip inside produces high-frequency oscillation signal (480kHz) through forming a high-frequency generator with the oscillating crystal of outside.This signal is sent into sinusoidal signal and the timing pulse signal that produces 40KHz behind the timing generator.Sinusoidal signal is sent into coding demodulator as carrier signal; Timing pulse signal is delivered to and is swept signal generator, keying input coding device and the command encoder time standard signal as these circuit.
The inner sweep generator of microprocessor chip produces the scanning pulse signal of five different times, and keyboard matrix circuit is delivered in output.When pressing a certain key, corresponding to the control signal of this function button respectively by being input to the keying encoder, the digital signal of output corresponding function.By keying encoder output order coded signal, on carrier signal, form the high-frequency pulse string that includes function information then, amplify, promote infrared light-emitting diode and launch pulse-modulated signal through transistor through modulators modulate.Be provided with corresponding infrared radiation receiving circuit, amplifying circuit, demodulator circuit and decoding circuit above television set or STB or the video tape recorder etc., carry out the guidance command that the user sends through remote controller.Perhaps adjust voice command or other order such as the channel selection order.
At present; Television set and STB can be selected suitable television channel through remote controller; The user is free to use television set or set-top box remote controller channel selection; General channel selection has two kinds of situation, the first through "+" perhaps "-" key transfer platform after being transferred to the platform of oneself liking, just to stop in order to watch, a kind of in addition situation is that the user knows and wants to see the numbering of directly selecting this channel with the numbering of program through keyboard.Also have one on the keyboard in addition and review key, when pressing this key, just can get back to a last program of watching.Use quite convenient, flexiblely, still, existing design can only make the user turn back to a program of watching, and just has to utilize numerical key input table number when the user need turn back to the program of front more watching.When forgetting platform number be, just need to use up and down key to search one by one, feel inconvenient when the user is used.
Summary of the invention
The present invention overcomes the remote controller of present television set or DTV STB in use, can only return a program of watching and can not return the inconvenience of front more watching that program brought and a kind of television channel of designing is selected remote control thereof and remote controller.
The present invention for realizing the technical scheme that its purpose adopts is: the method that a kind of television channel is selected; This method is provided with one " selected button " on remote controller, and defines the mode of reviewing key " double-click ", when pressing " selected button "; Confirm that the channel of watching is that a key returns the purpose channel; In the process of carrying out channel selection, when key is reviewed in double-click, turn back to described key and return the purpose channel.
Further, in the method for above-mentioned a kind of television channel selection: the work of remote controller may further comprise the steps:
Whether A, detection have button to press;
The button that B, judgement are pressed returns the purpose channel if the channel that described " selected button " then will watched is made as a key, otherwise turns to step C;
C, judgement are then sent the channel that a described key returns the signal of purpose channel if key is reviewed in double-click, otherwise, send corresponding channel.
The invention also discloses a kind of remote controller, comprise keyboard, microprocessor according to above-mentioned method; A selected button is set on described keyboard, and the channel of watching when described microprocessor is pressed described selected button is that a key returns the purpose channel, when key is reviewed in double-click, turns back to described key and returns the purpose channel.
Further, in the above-mentioned remote controller: described remote controller is the remote controller of DTV STB.Described selected button is " a red key ".
The present invention is not changing under the habitual function prerequisite of original return key; Expanded the function of remote controller tradition " return key "; Make the program that the user is watching; At present for no other reason than that reasons such as advertisement temporarily when arbitrarily browsing other program, when needing a key to return the program of watching the front, have been removed repeatedly button or even the channel trouble of thumbing one by one from.Bring great convenience to the user.
Description of drawings
Fig. 1 is a flow chart of the present invention.
Embodiment
Embodiment 1, and present embodiment is a kind of remote control thereof that DTV STB is carried out channel selection, and this method is provided with one " selected button " on remote controller; And the mode of key " double-click " is reviewed in definition; When pressing " selected button ", confirm that the channel of watching is that a key returns the purpose channel, in the process of carrying out channel selection; When key is reviewed in double-click, turn back to described key and return the purpose channel.
In the present embodiment " double-click " to judge also that except the time interval of judging 2 buttons the time interval of for the first time pressing key and reverse keys, (this time interval was less than certain value; Generally be in the 100ms); Here, " double-click " double-clicks similar with the use mouse on the remote controller.
