Description

A kind of visual TV remote controller

Technical field

The utility model relates to the remote control that uses on the television set, particularly visual TV remote controller.

Background technology

High speed development along with modern science and technology, the raising day by day of living standards of the people, increasing household electrical appliance enrich to daily life, television set is as development a collection of household electrical appliance early, through the development of nearly half a century, still be popularity rate nowadays, one of household electrical appliance that utilization rate is the highest.

See that TV is popular a kind of main flow life style.

The arrival of digital age has brought digital appliances miscellaneous, PDA, DVD, digital camera, Digital Video ... come into people's family one after another, we have to sigh with feeling: how lucky is the today that is in the scientific and technological enjoyment epoch! " greatly " television set as household electrical appliance is also constantly being innovated, pure flat, rear-projection, wall hung TV, Digital Television are come on stage one after another, yet the develop rapidly of television set hardware technology relatively, as if the television set step that (such as channel searching, mode of operation etc.) steps aspect software is also little, and the innovation of television set occupation mode has been neglected because of carelessness by the television set research staff.

Chinese originally common people are in and can only receive seven, eight cover TV programme, along with reform and opening-up, each local tv station has emitted like the mushrooms after rain, add the satellite television that strong CCTV and quantity are high, nowadays at home, can receive at home three, 40 the cover in addition four, 50 the cover TV programme be quotidian thing.

The mode of operation of television set develops into present widely used button remote controller by initial manual knob.Yet, the television set function is constantly perfect for many years, TV programme is being enriched constantly, and remote controller does not then have too big variation substantially, and " 0 " to " 9 " (or " 10 ") numerical key and " ↑ ", " ↓ " key all are " repertoire " on the telecontrol panel all the time.

See the TV switching channels except the direct button of 0-9 (or 10) channel, other channels add numerical key by " ↑ " " ↓ " key or "--" without exception and switch.

After a television set is bought back home; the TV programme that we can use the automatic function of search (or semi-automatic search) of television set to receive is usually searched for without exception; because the frequency location random distribution of TV programme; for the purpose of convenient; the program channel that we can often see oneself is adjusted to the position (0-10 channel) of front by " channel editor "; like this, the program channel that just can go directly and to see by primary key.At this moment we often find: some certain good program channels have to be set to " 10 " later position, because the button on the panel is limited after all.

When we wanted to see the program of the program of the 15th channel or 34 channels, most people can select the mode of comparison " stupid ": switch to the 15th channel or 34 channels one by one with " ↑ " or " ↓ " key.

Perhaps, this is a custom, perhaps is that people's inertia and inertia makes so, and doing does not so in a word have what not right, because people look for platform not want to tax one's brains, sees that originally TV diverts oneself exactly!

Such as: your these last few days is being watched TV series always, this serial is at " moon gulf arenas " of Shenzhen TV Station the 7th programs, when you turn on television set and remove to seek this program, perhaps, you will change platform one by one and go for this channel, often you will change tens platforms or twenties and just find this channel (in information blast, rhythm of life today efficiently, can remember that it definitely is minority that there is the people of which channel of television set in this program).

The aforesaid operations mode is not only loaded down with trivial details, not directly perceived but also efficient is low!

Summary of the invention

The purpose of this utility model provides a kind of novel visual TV remote controller that can effectively overcome the problems referred to above generation.It can consult the television channel name tabulation by the remote controller displays panel, and visualized operation is carried out in channel selection.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of visual TV remote controller comprises the control circuit in main body and the main body, also is provided with display floater on the main body, and described control circuit comprises: CPU, input unit, infrared transmitting element, memory cell, display driver unit; Wherein input unit, infrared transmitting element, memory cell connect with CPU respectively; The display driver unit is connected with display floater with central processing unit respectively.
