The image data being input into from the external equipment for being connected to external interface 101 is exported to display device 109.
Then, tuner 103 receives the sound of the channel broadcast in the frequency that ongoing frequency is set to by control unit 110
Sound is broadcasted, then the sound of the sound radio to receiving recovers, and is then exported.
When tuner 103 is set to signal source, control unit 110 is according to user to key switch 104 and rotary coding
The operation of device switch 105, the ongoing frequency to being set in tuner 103 carry out exception processes.
When below, for tuner 103 is set to signal source like this, control unit 110 is according to user to rotary coding
The operation of device switch 105, is said in order to change setting is processed in the manual tuning that the ongoing frequency of tuner 103 is carried out
It is bright.And manual tuning is processed when being to start from for tuner 103 being set as signal source.
Fig. 2 represents the order that manual tuning is processed.
As illustrated, in managing in this place, first the ongoing frequency for being set in tuner 103 is deposited as assigned frequency
Storage (step 202).
Then, monitor the generation (step 204) that user is operated to frequency lifting/lowering.Here, control unit 110 is rotary coding
Device switchs 105 clockwise turning operations and is accepted as frequency operation is lifted, and rotary encoder switch 105 is rotated counterclockwise
Operation is accepted as frequency operation is reduced.
If user has carried out the operation of lifting/lowering to frequency, then in audio process 106, export tuner 103
Output from sound to loudspeaker 107 stop (step 206).
Then, to user stops carrying out lifting/lowering operation to frequency (step 210), to operation compared with current value
Direction increases or reduces assigned frequency (step 208).If the operation for occurring is the operation for lifting frequency, assigned frequency is made
Increase the value corresponding to 105 amount of rotating clockwise of rotary encoder switch, if the operation for occurring is the low-frequency operation of drop, make
Assigned frequency reduces the value corresponding to 105 amount of rotating counterclockwise of rotary encoder switch.The step of control unit 110 here 204,
" assigned frequency acceptance apparatus " of 208 action part equivalent to claim.
In step 210, it is also possible to the numerical value of assigned frequency this moment is displayed in display device 109 and is processed.
Then, if the operation (step 210) of user's stop frequency lifting/lowering, proceed by the time-out with regulation (such as：
0.5 second) timing (step 212), monitor the generation of generation (step 214) and the timing time-out of the operation of the frequency lifting/lowering of user
(step 216).
If user enters the operation (step 214) of line frequency lifting/lowering, the process of step 208 is returned to.
On the other hand, when there is timing time-out (step 216), assigned frequency this moment is set as ongoing frequency
Tuner 103 is scheduled on, and thus, assigned frequency, i.e. user this moment is received by the specified frequency (step of frequency lifting/lowering operation
It is rapid 218).
Then, the reception electric-field strength of the channel of the ongoing frequency received by tuner 103 is obtained from tuner 103
Whether degree, investigated (step 220) in more than defined threshold Th to the received electric field strength that obtains.Here threshold value Th is used
Be the received electric field strength that can well receive radio minimum of a value.And, 218 the step of control unit 110,
" assigned frequency reception state investigation apparatus " of 220 action part equivalent to claim.
If the received electric field strength of the channel of ongoing frequency makes audio frequency process in more than defined threshold Th (step 220)
The sound that tuner 103 is exported by portion 106 again is exported (step 230) to loudspeaker 107, then returnes to step 202
Process.
On the other hand, if the received electric field strength of ongoing frequency is not reaching to more than defined threshold Th (step 220),
Centered on assigned frequency this moment, the assigned frequency scope of frequency is (such as：From assigned frequency -300KHz to assigned frequency+
The scope of 300KHz) as range of scanned frequencies, (step is scanned to the channel in range of scanned frequencies by tuner 103
222).Here, the assigned frequency scope for example can how many (between channel, frequency interval be big according to the good channel of current reception conditions
It is little) being set.For example, when the good channel of reception state is a lot, in the case of the equispaced very little between each channel, can
By the less of assigned frequency range set, on the contrary can be set it is bigger.On the whole can be by the assigned frequency range set
In 1MHz or following preferably.In the present embodiment, the assigned frequency scope be set to from assigned frequency -300KHz to specify
The scope of frequency+300KHz.But in step 222, current assigned frequency is included, by the frequency different from currently assigned frequency
Rate as the regulation of centre frequency frequency range as range of scanned frequencies, tuner 103 can be allowed to range of scanned frequencies
Interior frequency channel is scanned.I.e., such as, present assigned frequency by frequency upgrading operation set when, due to
Family carries out the delay of stop frequency lifting operation, and current assigned frequency becomes the frequency excessively more beneficial than the frequency increase that user wants
Probability it is big, it is possible to using the frequency range of the regulation of frequency centered on the frequency less than currently assigned frequency as scanning frequency
Rate scope.And, equally, such as, when current assigned frequency is set by frequency reduction operation, as user is stopped
Only frequency reduces the delay of operation, and current assigned frequency becomes the probability that the frequency wanted than user reduced the frequency of benefit
Greatly, it is possible to using the frequency range of the regulation of frequency centered on the frequency bigger than currently assigned frequency as scan frequency model
Enclose.
Namely in step 222, the minimum of a value for making to be set in the ongoing frequency of tuner 103 from range of scanned frequencies is to most
Big step frequency unit change of the value to specify, while each frequency set to as ongoing frequency, from tuner 103
Obtain the received electric field strength received by tuner 103.
If scanning (step 222) terminate, to reach more than threshold value Th received electric field strength frequency with the presence or absence of in
Investigated (step 224) in range of scanned frequencies, if it does not, assigned frequency this moment is set again as ongoing frequency
It is scheduled on tuner 103 (step 228).Then, the sound that tuner 103 is exported by audio treatment part 106 again is to loudspeaker 107
(step 230) is exported, the process of step 202 is then returned to.Here the step of control unit 110 222,224,226,
230 action part, and in step 220 when ongoing frequency frequency channel received electric field strength regulation threshold value Th more than
When, the action part of ongoing frequency is kept equivalent to " the receives frequency setting device " of claim.
On the other hand, (the step when the frequency for reaching threshold value Th above received electric field strength is present in range of scanned frequencies
Rapid that the frequency of the presence is set in tuner 103 (step 226) as ongoing frequency then 224), audio treatment part 106 is again
The sound that tuner 103 is exported is exported (step 230) to loudspeaker 107, then returnes to the process of step 202.
In step 226, it is present in range of scanned frequencies when there are multiple frequencies for reaching threshold value Th above received electric field strength
When interior, the frequency in the frequency for existing closest to assigned frequency this moment can be set in tuner 103 as ongoing frequency,
Can be in the frequency for existing, the frequency for reaching maximum received electric field strength is set in tuner 103 as ongoing frequency.
Or, it is also possible in step 226, according to apart from assigned frequency by entering remote order, the reception to each frequency
Electric-field intensity is investigated, and when finding to reach the frequency of threshold value Th above received electric field strength, terminates scan operation,
It was found that frequency be set in tuner 103 as ongoing frequency.
It is more than the explanation that manual tuning process is carried out about control unit 110.
Next, what Fig. 3 represented is specific process example that such manual tuning is processed.
As shown in Fig. 3 (a), for the channel of current these three frequencies of 91.3MHz, 98.1MHz, 104.3MHz, by these
Channel is set to channel of received electric field strength of the tuner 103 obtained by when receiving more than threshold value Th.I.e., now, Neng Goujin
The channel of the good reception radio of row is the channel of 91.3MHz, 98.1MHz, 104.3MHz.
Under such reception situation, shown in such as Fig. 3 (b), the frequency of the channel received in moment t0, tuner 103 (when
Front frequency) it is 91.3MHz (301), carried out from loudspeaker 107 by the sound of the radio of the CPCH reception of 91.3MHz
Output (302).
In this condition, between from moment t1 to t2, if user carry out lifted frequency operation (311), frequency from
If 91.3MHz increases to 98.0MHz, will stop exporting the sound (312) exported by tuner 103 from loudspeaker 107,
Moment t2, is altered to ongoing frequency 98.0MHz, and tuner 103 starts to receive 98.0MHz (321).
But as shown in Fig. 3 (a), the received electric field strength of 98.0MHz is not reaching to threshold value Th, so in moment t3, with
Proceeding by range of scanned frequencies (97.7MHz-98.3M) centered on 98.0MHz changes ongoing frequency and investigates reception
The scanning (331) of electric-field intensity.
So, in the scanning for being carried out from moment t3 to moment t4, in sweep limits, find more than as threshold value Th
Frequency 98.1MHz of received electric field strength, in moment t4, is set in tuner 103 using 98.1MHz as ongoing frequency, is opening
While beginning to receive 98.1MHz (341), voice output, the receipts of CPCH reception of the tuner 103 by 98.1MHz are carried out again
The sound of sound machine broadcast is output (342) from loudspeaker 107.
It is more than the explanation carried out by the specific embodiment of the present invention.
In addition, in the above embodiment, although expression is by by the rotating operation of rotary encoder switch 105
The situation for operating to be accepted as frequency lifting/lowering, but present embodiment is applied equally to installation lifting button and reduction
The key switch 104 of button, is accepted as frequency operation is lifted lifting button operation is pressed, is lifted the button phase pressing
Between, increase above-mentioned assigned frequency, accepted as frequency operation is reduced reduction button operation is pressed, frequency is reduced pressing
During rate button, above-mentioned assigned frequency is reduced.
Further, above embodiment can also be used and represent that any number of reception state quality replaces reception electric-field strength
Degree.Namely in this case, enter trade ongoing frequency reception state it is good when, 220 enter the step of manual tuning is processed
Enter step 230, when reception state is bad, into the process of step 222, enter the good receives frequency of trade reception state and exist
When in range of scanned frequencies, step 224 enters step 226, if be not present in the range of scanned frequencies, into step
228 process.
In addition, used as the numerical value for representing reception state quality, the broadcast for can also use SN ratios, receiving is relative in numeral
The signal that radio is received whether wrong occurrence rate of consistent or receiving data etc..
And, present embodiment is not only applicable to the receiver of radio, is applied equally to arbitrarily broadcast
The broadcasting receiver put.
In sum, according to present embodiment, user by frequency lifting/lowering operate, even if can not correctly frequency
Rate is set to that user wants the frequency for receiving, and in the case of being set to the frequency of deviation, by the frequency set by user
The frequency that the reception state of surrounding presence is good is estimated as the desired frequency that user wants setting by the operation of frequency lifting/lowering
Rate, and the frequency for receiving afterwards is set as by tuner 103.So, even if user cannot correctly frequency setting into
The frequency for receiving is wanted at family, also need not enter the operation of line frequency lifting/lowering again.
Therefore, by means of the invention it is possible to make the setting operation of the manually receives frequency that tuner operation is carried out become to hold
Easily.
