Embodiment
The formation of ※ broadcasting receiver
First, the formation of broadcasting receiver of the present invention is described with reference to Fig. 1.
Fig. 1 is the schematic diagram of the formation of broadcasting receiver 100 of the present invention.As shown in Figure 1, broadcasting receiver 100 of the present invention possesses: wave band switch key BANDSW, 6 preset key PRESET1 ~ 6, preset key state detection unit 110, idle preset key detecting unit 120, first repeated storage detecting unit 131, second repeated storage detecting unit 132, broadcasting frequency delete cells 140, broadcasting frequency buanch unit 150, memory cell 160 and microprocessors 101.
Wave band switch key BANDSW is made up of button or button etc., is operated by user.When wave band switch key BANDSW is operated, each wave band (quantity of wave band can set as required) is switched, thus enables each wave band share multiple preset key PRESET1 ~ 6.
6 preset key PRESET1 ~ 6 are made up of button or button etc. respectively, are operated by user, and each preset key can corresponding stored broadcasting frequency.When certain preset key in multiple preset key by user operate in a prescribed manner (without particular limitation of, can set as required) time, broadcasting receiver and this by certain broadcasting frequency of preset key corresponding stored of operating or obtain and this by the broadcasting frequency of preset key corresponding stored that operates to receive the program of this broadcasting frequency.
For example, when broadcasting receiver is receiving the program of certain broadcasting frequency, if user presses preset key and exceeds schedule time (time length can set arbitrarily as required), or, when user operates preset key and other buttons or button according to predefined procedure or predetermined combinations, then broadcasting receiver is just by the broadcasting frequency received and this is by the preset key corresponding stored operated; If user presses preset key (time length can set arbitrarily as required) within the stipulated time, or, when user operates preset key and other buttons or button according to predefined procedure or predetermined combinations, then broadcasting receiver stops receiving current program, and starts to receive with this by the program of the broadcasting frequency of preset key corresponding stored operated.
Preset key state detection unit 110 for detecting the state of the preset key be user-operably, that is, detects this by the preset key that operates whether corresponding stored broadcasting frequency.For example, suppose when as shown in table 1 with the broadcasting frequency of preset key PRESET1 ~ 6 corresponding stored, if preset key PRESET2 is operated, then preset key state detection unit 110 to have detected with this by the preset key PRESET2 corresponding stored that operates broadcasting frequency 87.5MHz; If preset key PRESET6 is operated, then preset key state detection unit 110 detects that the state of preset key PRESET6 is " free time " with this by the non-corresponding stored of the preset key PRESET6 any broadcasting frequency operated.
Idle preset key detecting unit 120 is for having detected with this by the preset key corresponding stored that operates broadcasting frequency during in preset key state detection unit 110, detect other preset key in multiple preset key, namely except by preset key whether available free among the preset key except the preset key that operates, and detect which preset key is idle preset key.
When there is not idle preset key for detecting at idle preset key detecting unit 120 in the first repeated storage detecting unit 131, detect broadcasting frequency that preset key receiving when being operated whether with in multiple preset key except by least one the preset key corresponding stored among other preset key except the preset key that operates, namely detect the broadcasting frequency that receiving whether with other preset key corresponding stored.
When there is not idle preset key for detecting at idle preset key detecting unit 120 in the second repeated storage detecting unit 132, detect and multiple preset key corresponding stored respectively broadcasting frequency among whether there is identical broadcasting frequency, namely detect other broadcasting frequency beyond the whether repeated storage broadcasting frequency received.
For the situation of table 1, further illustrate the first repeated storage detecting unit 131 and the second repeated storage detecting unit 132.In Table 1, suppose that the broadcasting frequency of PRESET6 corresponding stored is 100.9MHz, correspond to preset key PRESET1 ~ 6 like this and store broadcasting frequency 93.0MHz, these 6 broadcasting frequencys of 87.5MHz, 106.8MHz, 95.6MHz, 103.8MHz, 100.9MHz respectively, these 6 broadcasting frequencys are different, do not repeat.And suppose that the broadcasting frequency that now user is listening to is 99.1MHz.If when then active user presses any one in 6 preset key of above-mentioned corresponding stored broadcasting frequency, the broadcasting frequency due to 6 preset key equal corresponding stored, namely idle preset key is not had, now, because the broadcasting frequency 99.1MHz received is not identical with any one of the broadcasting frequency stored corresponding to above-mentioned 6 preset key, so the broadcasting frequency that the first repeated storage detecting unit 131 is receiving under just detecting the present situation is not redundantly stored.In addition, because the broadcasting frequency of 6 preset key corresponding stored is all different, so the second repeated storage detecting unit 132 detects that broadcasting frequency is not redundantly stored.If suppose the broadcasting frequency 106.8MHz of the preset key PRESET6 corresponding stored in table 1, then in the broadcasting frequency 93.0MHz stored respectively corresponding to preset key PRESET1 ~ 6,87.5MHz, 106.8MHz, 95.6MHz, 103.8MHz, 106.8MHz, broadcasting frequency 106.8MHz has 2, belongs to repeated storage.Now, the first repeated storage detecting unit 131 detects that the broadcasting frequency received is not redundantly stored, and the second repeated storage detecting unit 132 detects, broadcasting frequency 106.8MHz is redundantly stored.
Broadcasting frequency delete cells 140 detects and the broadcasting frequency by the preset key corresponding stored that operates in preset key state detection unit 110, and, when idle preset key detecting unit 120 detects that other preset key do not exist idle preset key, if the first repeated storage detecting unit 131 detects the broadcasting frequency that receiving and exists with each broadcasting frequency of multiple preset key corresponding stored and repeats, or by the second repeated storage detecting unit 132 detect with each broadcasting frequency of multiple preset key corresponding stored among exist and repeat, then from multiple preset key that broadcasting frequency repeats, select a preset key, delete with by the broadcasting channel of preset key corresponding stored selected, namely, delete by the corresponding relation of the broadcasting channel of the preset key selected and corresponding stored, this is made to be become " free time " by the state of the preset key selected, if the first repeated storage detecting unit 131, second repeated storage detecting unit 132 all detects to there is not repetition, then from multiple preset key, go out a minimum preset key of receive frequency (or selecting to receive number of times or the minimum preset key of time of reception) according to receive frequency selective sequential from low to high, to delete with this by the broadcasting channel of preset key corresponding stored selected, make this be become " free time " by the state of the preset key selected.Wherein, so-called " receive frequency " refers to for a broadcasting frequency, number of times received in the unit interval.If received number of times is more in the broadcasting frequency unit interval, namely receive frequency is higher, illustrates that the favorable rating of user to this broadcasting frequency is higher.Such as in following table 4, suppose the unit interval for " my god ", the reception number of times embodied in the received table of broadcasting frequency 1 ~ 7 number of days used is respectively: 30 days, 10 days, 40 days, 30 days, 30 days, 50 days, 10 days.Receive frequency in this table be according to above-mentioned data calculate for each broadcasting frequency, average one day receive number of times.
Broadcasting frequency buanch unit 150 is for detecting other preset key namely by preset key available free among the preset key beyond the preset key that operates during at idle preset key detecting unit 120, or when broadcasting frequency delete cells 140 deletes the corresponding relation of certain preset key and broadcasting frequency and makes this preset key become idle preset key, get up with by the broadcasting frequency operating preset key corresponding stored with the some corresponding stored in idle preset key.
Memory cell 160 is made up of, for storing various data and information semiconductor memories such as the CD such as hard disk, CD and DVD or SRAM memory.Such as, in memory cell 160, each broadcasting frequency and multiple preset key corresponding stored can be got up, can also as table 4, stored record reception number of times, time of reception, the receive frequency of each broadcasting frequency.
Reception number of times, time of reception, the receive frequency of [table 4] each broadcasting frequency
| No. | Broadcasting frequency | Receive number of times | Time of reception (minute) | Receive frequency |
| 1 | 87.5MHz | 50 | 1500 | 1.7(＝50/30) |
| 2 | 101.5MHz | 30 | 1303 | 3.0(＝30/10) |
| 3 | 90.5MHz | 60 | 1765 | 1.5(＝60/40) |
| 4 | 95.5MHz | 44 | 201 | 1.5(＝44/30) |
| 5 | 88.5MHz | 23 | 87 | 0.8(＝23/30) |
| 6 | 103.5MHz | 123 | 6287 | 2.5(＝123/50) |
| 7 | 99.5MHz | 28 | 86 | 2.8(＝28/10) |
| …… | …… |
Wherein, in the column " receive frequency " of form, the numeral of record is less, represents that receive frequency is lower.
Microprocessor (control unit) 101 is made up of CPU or MCU etc., the broadcasting frequency received when preset key is operated as " want store broadcasting frequency ", and with this by the preset key corresponding stored that operates in memory cell 160.Microprocessor 101 is connected with each Component units of broadcasting receiver, and controls these unit, to realize various function and the action of broadcasting receiver.
The workflow of ※ broadcasting receiver
Then, the workflow of broadcasting receiver of the present invention is described with reference to Fig. 2.
Fig. 2 is the workflow diagram of broadcasting receiver of the present invention.When supposing user's broadcast listening program, want broadcasting frequency and certain preset key corresponding stored of the program received by broadcasting receiver 100, so operate this preset key according to the mode (such as pressing preset key more than 2 seconds) of regulation.In this case, broadcasting receiver starts by the broadcasting frequency received and by the pre-stored action (step S501) of preset key corresponding stored among memory cell 160 operated.
Then, preset key state detection unit 110 detects whether the preset key by operating is idle preset key (step S502).If preset key state detection unit 110 detects that by the preset key operated be idle preset key (being "Yes" in step S502), then by the broadcasting frequency received and by the preset key corresponding stored (step S509) in memory cell 160 operated, and terminate pre-stored action.Otherwise, if preset key state detection unit 110 detects that by the preset key operated be not idle preset key (in step S502 for "No"), then idle preset key detecting unit 120 detect in multiple preset key except whether being idle preset key (step S503) by other preset key except the preset key that operates.
Now, if idle preset key detecting unit 120 detects that the one or more preset key in other preset key are idle preset key (being "Yes" in step S503), then broadcasting frequency buanch unit 150 by with by the broadcasting frequency of preset key corresponding stored operated, with one of the idle preset key detected corresponding stored (step S512) in memory cell 160, then perform step S509, and terminate pre-stored action.
Otherwise, if idle preset key detecting unit 120 detects that other preset key are not idle preset key (in step S503 for "No"), then the first repeated storage detecting unit 131 judge the program received broadcasting frequency whether with other preset key among certain or certain several preset key corresponding stored (step S504).
Now, if the first repeated storage detecting unit 131 judge the program received broadcasting frequency with other preset key among certain or certain several preset key corresponding stored (being "Yes" in step S504), then broadcasting frequency delete cells 140 deletes the corresponding broadcasting frequency stored of one of preset key of this broadcasting frequency received of corresponding stored, makes this preset key become idle preset key (step S510).Then, broadcasting frequency buanch unit 150 by with by the broadcasting frequency that operated preset key corresponding stored with become idle idle preset key corresponding stored (step S512) in memory cell 160 by broadcasting frequency delete cells 140.Then, perform step S509, and terminate pre-stored action.
Otherwise, if the first repeated storage detecting unit 131 judge the program received broadcasting frequency not with other preset key among certain preset key corresponding stored (being "No" in step S504), then the second repeated storage detecting unit 132 judges whether the corresponding broadcasting frequency stored of all multiple preset key has the broadcasting frequency (step S504) of repetition (namely identical).
Now, if the second repeated storage detecting unit 132 judges that the corresponding broadcasting frequency stored of all multiple preset key has the broadcasting frequency (as "Yes" in step S505) of repetition (namely identical), then broadcasting frequency delete cells 140 has deleted with corresponding stored the broadcasting frequency of certain the preset key corresponding stored among multiple preset key of this identical broadcasting frequency, namely delete the corresponding relation of this preset key and broadcasting frequency, make this preset key become idle preset key (step S511).Then, broadcasting frequency buanch unit 150 by with by the broadcasting frequency that operated preset key corresponding stored with become idle idle preset key corresponding stored (step S512) in memory cell 160 by broadcasting frequency delete cells 140.Then, perform step S509, and terminate pre-stored action.
Otherwise, if the corresponding broadcasting frequency stored of all multiple preset key of judging the second repeated storage detecting unit 132 does not repeat the broadcasting frequency (being "No" in step S505) of (namely identical), then microprocessor 101 to by the broadcasting frequency of preset key corresponding stored that operates listen to frequency or time of reception etc. and and listen to frequency or the time of reception etc. of broadcasting frequency of other preset key corresponding stored compare (step S506), and, to judge and whether be minimum (step S507) by listen to frequency or the time of reception etc. of the broadcasting frequency of preset key corresponding stored that operate.
Now, if microprocessor 101 is judged as and be minimum (being "Yes" in step s 507) by listen to frequency or the time of reception etc. of the broadcasting frequency of preset key corresponding stored that operate, then broadcasting frequency delete cells 140 delete with by the broadcasting frequency of preset key corresponding stored operated, become idle preset key (step S513).Then, perform step S509, and terminate pre-stored action.
Otherwise, if microprocessor 101 is judged as and be not minimum (being "No" in step s 507) by listen to frequency or the time of reception etc. of the broadcasting frequency of preset key corresponding stored that operate, then broadcasting frequency delete cells 140 is deleted and the broadcasting frequency listening to the minimum preset key corresponding stored such as frequency or time of reception, become idle preset key, then, by with by the broadcasting frequency of preset key corresponding stored that operates and this idle preset key corresponding stored (step S508).Then, perform step S509, and terminate pre-stored action.
The change of ※ broadcasting receiver
Above, see figures.1.and.2 the formation describing broadcasting receiver of the present invention and workflow.But the present invention is not limited thereto, various change can be carried out as required.
Such as, in the broadcasting receiver shown in Fig. 1, there are wave band switch key BANDSW and 6 preset key PRESET1 ~ 6, but the quantity of wave band switch key and preset key is not particularly limited, and, the wave band switch key of shared preset key also can not be set.
In addition, in the formation of the broadcasting receiver shown in Fig. 1, comprise the first repeated storage detecting unit 131, second repeated storage detecting unit 132 and broadcasting frequency delete cells 140, but, certainly can not comprise this three unit, or only include one of them.Equally, in the workflow shown in Fig. 2, describe step S504 ~ S508, but, certainly can a step as required in delete step S504 ~ S508 or multiple step, and form new workflow.
In addition, in broadcasting receiver as above and workflow thereof, all first deleted and the broadcasting frequency of a certain preset key corresponding stored and make after this preset key becomes idle preset key by broadcasting frequency delete cells 140, the broadcasting frequency that idle preset key corresponding stored stores corresponding to the preset key that operates with this again, but, a certain preset key can not certainly be made to become idle preset key by broadcasting frequency delete cells, but with certain preset key directly cover accordingly store with by the broadcasting frequency of preset key corresponding stored operated.So, broadcasting frequency delete cells can not be set.
The embodiment of ※ broadcasting receiver
Below, by embodiment 1 ~ 5, broadcasting receiver of the present invention is described in more detail.
