The present invention relates to a kind of memory that is used for selecting channel with frequency synthesizer, and use this memory to select the system of channel with frequency synthesizer, in each position of this memory, have to be used to store and select and receive memory block corresponding to the channel information of receivable channel, this memory is used in selecting in the system of channel with frequency synthesizer of television receiver or similar device, and this system has by location number to be selected channel and selected the function of channel by channel.
So far, in television receiver, for example, method as the channel of selecting to want, employing is selected the memory (FS selection memory) of channel with frequency synthesizer, in each position of this memory, has to be used to store and selects and receive memory block corresponding to the channel information of receivable channel, used system's (FS selective system) of selecting channel with frequency synthesizer, it has by location number (POS) selects channel and selects two kinds of functions of channel by channel (CH).
Fig. 2 illustrates common FS selective system, being used for of wherein will receiving select and receive the information stores of wanting the channel that receives and be preset in the FS selection memory.In Fig. 2, the receivable channel of label 11 representative, the 12nd, in each position, have the FS selection memory of memory block.
Below be described in common FS selection memory and the work of using in the FS selective system that constitutes by these element.
Positional number (for example, the POS of the memory block of in common FS selection memory 12, arranging 0To POS 49) less than receivable channel number (for example, the CH of channel 11 0To CH 125) (CH number＞POS number), in the FS selective system that adopts it, according to the Serial No. that is received location number in the channel sequence, be used to select and receive the method for the information (such as color system and sound intermediate frequency (SIF)) of certain passage with a kind of setting, the information of selecting and receive each receivable channel is preset in the memory block that is arranged in each position.
Do this presetting, up in all location numbers, all presetting, plant thus and preset action, and according to certain is used to select channel information with receiving channels corresponding to depositing each receiving channels in the memory 12 in, can select or CH selects the channel wanted by POS.
Yet, in common FS selection memory and its FS selective system of use, when receivable channel number increases gradually, though can receive certain special channel, but positional number is not enough so can not preset the information that is used to select and receive this channel, can not select this channel by POS.In addition, location number is usually different with channel, thus need remember to be used to select and the information that receives which channel is inserted the memory block of which position in advance, if forgotten, he must select channel with reference to the table of comparisons of corresponding location number and channel, thereby need do a very complicated job.
On the contrary, when the channel selecting by CH to want, at first press CH options button (not shown) to be set in the CH selection mode, the number button (not shown) of pressing the channel of wanting is to select that channel, and this operation is also very complicated, though can be by the direct channel selection of channel, but by this operate in be used in the memory block of presetting the people position when CH selects to select with the information of receiving channels can not be always be used to select and to receive the channel information of selected channel consistent, so may occur that color is lost or sound accompaniment such as loses at trouble.
In addition,, only see that screen do not know that the program that illustrates at present is to be selected or selected and chosen by POS by CH because select channel that two kinds of methods are arranged, for example, when selecting to see CH by CH 10, and choose POS with the channel duplicate numbers that illustrates at present by POS 10The time, screen may become, for example, and CH 12, this bothers very much.
The present invention is in order to overcome the above problems, thereby its main purpose provide can simplify the complex operations of selecting channel and can improve control ability select the memory of channel with frequency synthesizer, and with the system that uses it with frequency synthesizer selection channel.
For reaching this purpose, of the present inventionly select the memory block of the memory of channel to have to equate or the more positional number of quantity with the receivable channel number with frequency synthesizer, and its system with frequency synthesizer selection channel of use of the present invention comprises: be used for selecting with frequency synthesizer the memory of channel, be used for selecting and receiving corresponding to each receivable channel storage the information of a certain channel; The POS information-processing circuit, select in the memory block of channel by successively the information of selecting and receive a certain channel being deposited in frequency synthesizer, thereby when presetting, channel is consistent mutually with location number, and takes out the information that is used to select and receive a certain channel when selecting channel from the memory block of selecting channel with frequency synthesizer; And according to the selection channel treatment circuit that is used to select to select channel with the information of receiving channels.
According to this structure, because select the memory block of the memory of channel to have number of locations number that equate with receivable channel number or more with frequency synthesizer, so can the occurrence positions number shortage or similar trouble, when the information of selecting and receive each channel being inserted the memory block of each position in advance by prepositioned instruction, POS information processing circuit is successively selecting and receive channel information corresponding to each receivable channel to deposit in frequency synthesizer and select in the memory of channel, thereby makes channel and the location number can be consistent mutually.Correspondingly, pre-postpone needn't reset, and can select any receivable channel.
In addition, being used to of in the memory block of selected position, presetting select with the information that receives a certain channel always be used to select and to receive the information of selected channel consistent, thereby can prevent to lose or sound accompaniment such as loses at trouble such as color.
In addition, as broad as long between CH selection and POS select, simplified and selected the operation of channel and improved control ability.
With reference now to accompanying drawing,, it is as follows to describe preferred embodiment of the present invention.
Fig. 1 is the block diagram of using the FS selection memory in the preferred embodiment of the present invention and adopting its FS selective system; (wherein ※ is the information that is used to select and receive certain channel); And
Fig. 2 is the key diagram (wherein CH number＞POS number) by the FS selective system pre-set channel that adopts common FS selection memory.
Generally, in television receiver, radio receiver and different Ridio communications device, the user is with the FS selection memory and adopt its FS selective system to select the channel of wanting, and describes the FS selection memory here and adopts its application of FS selective system in television receiver.
