Abstract

The utility model relates to a remote control and station selecting device for a television. Twenty six English letters are appended to numeric keys of a numeric keyboard of a remote controller of the utility model, and keys for selecting stations, programming and switching are additionally arranged on the numeric keys. A data memory is added inside a central processor. The names and preset sequence numbers of channels of the television stations are stored in the data memory after programming. When a user types in the name of the television station of a channel program for watching on the numeric keyboard, the remote controller can send to a receiving controller inside the television, and the program of the selected television station can be watched immediately. The remote control and station selecting device for a television can be operated conveniently and quickly, and the trouble of remembering the sequence numbers of the channels or looking for one by one can be left out.

Description

The TV remote channel selecting device

The utility model relates to digital communications treatment technology scope, particularly a kind of TV remote channel selecting device.

Existing TV remote channel selecting device mainly by remote controller, receives controller and forms in the machine.During the one digit number keyboard, remote controller sends signal on pressing remote controller, and receiving system will identify the name of pressing the key position in the machine, send subsequent instructions then and finish the channel selection function.To select the channel of two digits equally, at first to remember each TV station in television set channel preset item, press on the remote controller "/--" key during operation earlier, press required double figures keyboard subsequently, on television screen, demonstrate the platform number and the channel digit of selected channel; Another kind of way is on the basis of television channel at that time, press " P Λ " or " PV " key on the remote controller, looks for singly successively, and is so both time-consuming, bothers especially again.Especially the number along with television channel day by day increases, and nearly dozens of is looked for singly and quite felt inconvenience to up to a hundred.

The purpose of this utility model provides a kind of TV remote channel selecting device, and having the rating people only needs the TV station's title that will see program is keyed on remote controller, just can select quickly and easily and desire to see programme channel.

The purpose of this utility model is achieved like this: a kind of TV remote channel selecting device comprises in remote controller, the machine and accepts controller.Described remote controller is by reflector 1, controller 2, and numeric keypad 3 and other function keys are formed.Additional on the numerical key 3.1 of described numeric keypad 3 have English alphabet 3.4, also set up "=" number key 3.2 and MODE channel selection, programming switch key 3.3.When pressing MODE key 3.3, controller 2 is in programming state, by the programming signal of numerical key 3.1 selected numerals of input and letter 3.4, and through central processing unit cpu2.1, after program memory ROM 2.2 calculation process, data memory input RAM2.3 storage.During channel selection, after keying in selected letter row from 0-9 numerical key 3.1 again, press "=" key 3.2 again, controller 2 will retrieve selected TV station from data storage RAM2.3 platform position digital signal is sent to reception controller 4 in the television set by reflector 1, promptly occurs institute's channel selection program on the screen.Sound, light prompting device 1.1 in reflector 1, have also been added.

The reflector 1 of described remote controller can also directly propose the channel selecting signal of keying in the second way from RAM2.3, all be sent to the signal receiver 4.1 that receives controller 4 in the machine then, signal is input to signal receiving processor 4.2, after program storage RAM4.3 programming, deposit 2 4.5 storages of new channel data memory RAM in; After channel selecting signal is imported from information recipient 4.1, signal is accepted processor 4.2 and retrieve the selected channel signal from channel data memory RAM 2 4.5, transport to frequency modulated video signal in 4.6 pairs of machines of additional frequency modulation device, convert this signal input signal modular converter 4.7 to picture intelligence again, show on the TV screen again.

The utility model TV remote channel selecting device with prior remote controller relatively, its advantage is: owing to preset TV station's title and corresponding channel position in advance in RAM, rating people only needs the phonetic of each TV station and platform number, on numeric keypad, key in, just can see at once want the station synchronization seen, saved the channel number of remembering each TV station, or the trouble of looking for singly.This TV remote channel selecting device cost cost is low, practical, easy and simple to handle, quick, and people take like a shot.

Below in conjunction with description of drawings, the utility model is further specified.

Fig. 1 is commercially available TV remote controller numeric keypad layout.Fig. 2 is Fig. 1 remote control circuitry schematic diagram.Fig. 3 is a TV remote channel selecting device numeric keypad layout.Fig. 4 is TV remote channel selecting device circuit theory diagrams.Fig. 5 is the interior controller circuitry schematic diagram that receives of the machine of TV remote channel selecting device.

Fig. 1 and Fig. 2 are the numeric keypad layout and the circuit theory diagrams of commercially available TV remote controller.Controller 2, reflector 1 that it is made up of numeric keypad 3, central processing unit cpu2.1 and program memory ROM 2.2 are formed.

From the keyboard layout of Fig. 3 numeric keypad, on the numerical key face, increased the arrangement of English alphabet 3.4, and set up "=" number key 3.2 and " MODE " key 3.3.

By Fig. 4 circuit theory diagrams as can be known, the remote controller of this TV remote channel selecting device is by the reflector 1 that has sound, light prompting device 1.1, by the controller 2 that has increased data storage RAM2.3 and set up "=" number key 3.2 and " MODE " key 3.3 and be attached to numeric keypad 3 formations that English alphabet 3.4 on the numerical key 1.1 is formed." MODE " key 3.3 in Fig. 4 is channel selection and programming switch key, when programming, press " MODE " key 3.3 expression remote controllers and be in programming state, at first using to add has 0-9 numerical key 3.1 of 26 English alphabets 3.4 to programme, in specified time interval, numerical key 3.1 clicks expression and keys in first character on the key, double-click expression and key in second character on the key, and the like.The channel selecting signal of its key entry deposits signal among the RAM2.3 in after entering CPU2.1 and ROM2.2 calculation process.When channel selection, not according to " MODE " key 3.3, remote controller is in the channel selection state, according to aforementioned still press on the ten key 3.1 the letter and digital, after key entry wants the letter of the name phonetic of channel selection name to add this sequence number again, then by "=" key 3.2, at this moment remote controller retrieves the pre-set channel sequence number of institute's channel selection from RAM2.3, reflector 1 is sent to this channel number signal and is received controller 4 in the television set machine, identify channel number by former data storage 4.4, be presented on the screen, rating people just can see selected station synchronization at once.

Fig. 5 receives the controller circuitry schematic diagram in the improved machine.When the reflector 1 of remote controller is emitted to the receiver 4.1 that receives controller 4 in the machine to the signal that TV station's phonetic and channel are arranged, this signal is programmed by its central processing unit CPU4.2 and program memory ROM 4.3, again by channel data memory RAM 2 4.5 storages of newly adding.When the rating people when the numerical key 3.1 of remote controller is keyed in TV station's title of desiring TV receptions, sequence number and channel, receive controller 4 retrieves the channel selecting signal of receiving this channel selection through central processor CPU 4.2 and channel data memory RAM 2 4.5 data-signal in the machine, after carrying out frequency modulation again by 4.6 pairs of videos of frequency modulation device, input to signal conversion module 4.7, convert TV station's title, sequence number and channel that picture intelligence shows intuitively that on TV screen the rating people will see to.Need only select once and just can see the program of desiring to see.
