Description

A kind of remote controller that can receive public information

Technical field

The utility model relates to a kind of remote controller of household electrical appliance, particularly relates to the TV remote controller that a kind of built-in wireless receiving module can receive public information.

Background technology

When television channel was increased to some, spectators usually felt mixed and disorderly and inconvenient when selection and TV reception, wear down plenty of time driftlessness ground search and wait for programs of interest before television set, caused physiology and psychological discomfort.List of television programmes can make spectators to comprehensive understanding being arranged, planned on purpose TV reception with the program that will broadcast.

The main method that present spectators obtain list of television programmes is broadcasting ﹠ TV news or other newpapers and periodicals, owing to be subjected to the restriction of the space of a whole page and cost, content is detailed inadequately, and program is searched very inconvenient.

Among existing radio paging system and the FM RDS (Remote Data Services), oriented very early user provides the effort of other public information services such as list of television programmes, product advertising, and this service is still continuing at present.Because receiver adopts the form of beep-pager, stock handset or pager usually, its product external form is restricted the user group, and receiver can't be popularized in a large number and enter family, and information service also can't effectively be carried out always.In radio paging technology, generally adopt POCSAG (Post Office Code StandardizationAdvisory Group) coding standard at present

In an at present known foreign patent technology, adopt the form of TV set-top box, by built-in radio call receiver received television program table and other information, by television receiver display program table and other information.The core of this technology is the issue of accurate listing and based on the automatic control to program of listing, as performance recording and advertisement filtering etc., the out of Memory service then mainly is that television set is used as display.As a kind of listing service, the program controlled function that accurate listing issue is provided not is that the televiewer generally needs.With regard to understanding this simple functions of program broadcasting time, the scheme that this technology provided is too complicated, cost is high and inconvenient use.Information service depends on television set, and type service and place are restricted.In China, television set generally is a plurality of kinsfolks services simultaneously, and the clear information on services of readding is then carried out alone by a people usually, and the existence of this contradiction has determined this technology to be difficult to the public to accept.

Because the defective that above-mentioned prior art exists, the inventor is actively studied innovation, through constantly studying, designing based on abundant practical experience and professional knowledge, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.

Summary of the invention

Main purpose of the present utility model is, provides a kind of built-in wireless receiving module can receive the remote controller of public information.The related list of television programmes service of present technique is to satisfy the public and understands a kind of like this primary demand that simply has generality of television program transmission time, utilization has a kind of so simple and natural product form of TV remote controller of list of television programmes and is realized, is a kind of service ready to hand whenever and wherever possible.Built-in display on remote controller, make it can be totally independent of television display, thereby kept the removable characteristic of radio call terminal, public information service needn't be subjected to the place and whether the restriction of television set is arranged, have wider crowd and region applicability, the information service kind that can provide is also more.

The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions.According to a kind of remote controller that can receive public information that the utility model proposes, comprise remote controller keyboard scan array, remote controller transmitting tube, it is characterized in that also including information receiving module, display screen, central processing unit and memory module, wherein: information receiving module is connected with memory module with central processing unit respectively with display screen, control by central processing unit, information receiving module can receive public information and be stored in the memory, and demonstrates public information on display screen.

The aforesaid remote controller that can receive public information, wherein said information receiving module are POCSAG radio call receiver module or FM RDS receiver module.

The aforesaid remote controller that can receive public information, wherein said keyboard scan array, remote controller transmitting tube also are connected with memory module with central processing unit respectively.

The aforesaid remote controller that can receive public information, wherein said display screen are the LCD LCDs, and described remote controller transmitting tube is an infrared transmitting tube, and described remote controller is a TV remote controller.

The utility model compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, the utility model is with low cost with two of radio call terminal (or FM RDS terminal) and TV remote controller, technology maturation and originally fully independently technology combine, satisfy the demand of the public in natural mode to list of television programmes.The generality of list of television programmes demand and the low cost of product and simplicity have determined this TV remote controller can enter family on a large scale.After above-mentioned remote controller enters family in a large number, can form one towards ordinary consumption family, public information delivery network powerful, with low cost, easy to use.When list of television programmes is provided, provide other public informations such as government notice, product advertising, information on services.

In sum, the utlity model has above-mentioned many advantages and practical value, and in like product, do not see have similar structural design to publish or use, no matter and it structurally or bigger improvement all arranged on the function, have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really, thereby being suitable for practicality more, really is a new and innovative, progressive, practical new design.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
