Abstract
The present invention relates to a method and a device for television reception. Image material played in real time by all channels of pre-selection tuned television channels are edited into an image menu, and are divided into sections according to positions to be simultaneously displayed on a screen of a display device; simultaneously, the positions of (remote-control or native) keys of a menu keyboard for program selection are corresponding to the geometric positions of the screen screens; corresponding keys are pressed according to the positions of the images on the screen, and a selected program can be instantly obtained. The present invention has the advantages of multi-channel and real-time properties.
Description
The present invention relates to a kind of system of selection and device of television channel program, particularly by the programme content of browse graph as menu screen, directly quick method and the device of selecting to watch program.
General television set is by the way of channel lifting one by one, or from the way of the storage numbering of certain channel TV of control device input the television channel of watching is selected.Such system of selection lacks real-time and simplicity, and especially at local television channel numerous (as dozens ofs), and during unknown multiple channels of program content, the selection of television channel program is complicated and time-consuming especially.
(day for announcing: on August 2nd 4,1994) disclosed " TV multi-menu co-screen display controller " proposed a kind of multi-menu co-screen display unit that is used for multi-channel video signal to notification number CN2175502Y, shows the multi-channel video live image simultaneously on a display screen.It adopts universal elements and picture-in-picture module, constitutes the multi-menu co-screen display controller with hardware, has realized the identification and the demonstration of multi-picture signal.Because the restriction of hardware circuit, this device can only realize the same screen of maximum 4 movable sprites of maximum 5 tunnel vision signals and show, and this document does not relate to the method that how obtains the multi-channel video picture signal from the multi-channel television radiofrequency signal.
Publication number CN113541A (open day: on November 6th, 1996) disclosed " being used to produce the device of the PIP/POP screen of a plurality of quasi-movings " a kind of device that produces a plurality of picture-in-pictures/picture out picture screen is proposed, it adopts microcomputer and the pattern that picture-in-picture/the picture out picture processing unit combines, and has realized the many pictures picture-in-picture/picture out picture function of television set.Main screen tuned cell in this device and secondary screen tuned cell are controlled by same microcomputer, the PIP/POP screen generation unit of the quasi-moving in this device, it is picture-in-picture/picture out picture signal processing unit carries out picture-in-picture/picture out picture to vision signal processing, and output is used for the tuning control signal of channel change to microcomputer, carries out channel by Controlled by Microcomputer sprite tuner and switches.By the circuit form of a microcomputer (or microprocessor) control main screen tuned cell and secondary screen tuned cell, when calling many pictures sub-screen, can cause slow that little picture image manifests.
The television set of band picture-in-picture function has made things convenient for the user, makes under the situation that keeps the key frame program, supervises the program picture of little picture, for the selection of TV programme provides convenience.The picture-in-picture of the television set of band picture-in-picture function has two kinds of forms when showing usually, and the one, at the programme content of auxilliary screen displayed single television channel, the 2nd, in auxilliary picture, show the programme content of a plurality of television channels simultaneously with accurate manner.Under the picture-in-picture demonstration situation of first kind of form, the user needs the method for channel lifting one by one, and the programme content that changes auxilliary picture shows, when watching satisfied program, main and auxiliary picture is switched or imports the memory location numbering of auxilliary picture channel, make the key frame display program content.Under the picture-in-picture demonstration situation of second kind of form, the user can observe the programme content of a plurality of channels in the auxilliary picture, prompting according to other this channel memory location numbering that shows of multichannel image in the auxilliary picture, import this numbering, make key frame show the programme content of selecting, or use input unit, the selection marker in the mobile auxilliary picture is to desiring to watch in the sprite of channel correspondence, press acknowledgement key, key frame is switched to the program picture of confirming channel.Therefore, the television set of band picture-in-picture/picture out picture function is selecting to provide convenience aspect the TV programme for the user, but does not obtain simplifying in the operation that program is selected.
The object of the present invention is to provide a kind of menu image picture that can show a plurality of television channel broadcast items simultaneously, and browsing by the menu image picture, a kind of television receiver picture menu programme selecting method and the device of the TV programme that direct selection will be watched are to overcome the defective of above-mentioned prior art.
The method of the television receiver picture menu programme selecting that the present invention proposes: be the program image that is broadcasting by the tuning a plurality of television channels of preliminary election, compile the menu image picture, opsition dependent is divided into a plurality of sub-districts and shows on video picture device screen; The quantity of the menu keyboard (remote control or this machine) of selection program is corresponding with the position with the quantity of position and video picture device screen partition, according to the position of the program image frame of desiring the frequency-selecting road at video picture device screen partition, press corresponding key on the menu keyboard, screen shows selected program image frame at once, finished the TV programme selection course, action that need not be complicated fully, needn't remember the storage numbering of television channel, also need not understand the program arrangement of each television channel, reach the effect of selecting TV programme quickly and easily.
