The modulation sound signal processing of then, the broadcast receiver by above-mentioned explanation being carried out describes.
(first execution mode)
In some countries, broadcast modulated acoustic tone signal (the first modulated acoustic tone signal) and the ovennodulation voice signal of modulating with the modulation degree different (second modulation degree) (the second modulated acoustic tone signal) sometimes with the specified modulation degree with specified modulation degree (first modulation degree) modulation.
The control assembly of broadcast receiver (assignment component) 110 can be a modulated acoustic tone signal tupe (signal processing model) of from a plurality of modulated acoustic tone signal tupes (a plurality of signal processing model), selecting to each channel setting, and storage is to the modulated acoustic tone signal tupe (signal processing model) of each channel setting.For example, a plurality of modulated acoustic tone signal tupes of memory 111 storages, and further store modulated acoustic tone signal tupe to each channel setting.
Thus; The acoustic processing assembly 107 of broadcast receiver (modulation signal processor 107) can be with reference to the modulated acoustic tone signal tupe that is stored in each channel in the memory 111; And according to the modulated acoustic tone signal tupe (signal processing model) to selected channel setting, the modulated acoustic tone signal (modulation signal) of the channel that treatment of selected is selected.
For example; If the user indicates the selection of first channel through first channel key of remote controller 114; Then corresponding; First broadcast singal of first channel selected and exports by tuner (channel selector) 102 from receiving broadcast signal; Image processing component 104 is handled and output is included in the signal of video signal in first broadcast singal, and acoustic processing assembly 107 (modulation signal processor 107) is according to the first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe to first channel setting, and processing and output are included in the voice signal in first broadcast singal.Then, image display part (output precision) 106 shows that based on the image that is included in the signal of video signal in first broadcast singal loud speaker 108 outputs are based on the sound that is included in the voice signal in first broadcast singal.
The first modulated acoustic tone signal tupe is to be used to handle the pattern with the first modulated acoustic tone signal of first modulation degree modulation.For example, the first modulated acoustic tone signal tupe is the pattern that is used under the situation of not proofreading and correct the modulated acoustic tone signal, handling the modulated acoustic tone signal.And the second modulated acoustic tone signal tupe is to be used to handle the pattern with the second modulated acoustic tone signal of second modulation degree modulation.For example, the second modulated acoustic tone signal tupe is to be used for after proofreading and correct the modulated acoustic tone signal modulating the pattern that voice signal is handled.
As stated; Under the state of having selected first channel (state that first broadcast singal of first channel is arranged in output); The user can change the first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe to first channel setting through the mode initialization key of remote controller 114.
For example; At the state of selecting first channel and under the state of first channel setting, the first modulated acoustic tone signal tupe; If press the mode initialization key of remote controller 114; 110 pairs first channel settings of control assembly (assignment component), the second modulated acoustic tone signal tupe then, memory 111 storages are to the second modulated acoustic tone signal tupe of first channel setting.
In addition; Under the state and state of selecting first channel to first channel setting, the second modulated acoustic tone signal tupe; If press the mode initialization key of remote controller 114; 110 pairs first channel settings of control assembly (assignment component), the first modulated acoustic tone signal tupe then, memory 111 storages are to the first modulated acoustic tone signal tupe of first channel setting.
For example; In the modulated acoustic tone signal of first channel is under the situation with the first modulated acoustic tone signal of first modulation degree modulation; If to first channel setting, the first modulated acoustic tone signal tupe; Then the modulated acoustic tone signal of first channel is suitably handled, from the less high-quality sound of loud speaker 108 output distortions.
On the contrary; In the modulated acoustic tone signal of first channel is under the situation with the second modulated acoustic tone signal of second modulation degree modulation; If to first channel setting, the first modulated acoustic tone signal tupe; Then the modulated acoustic tone signal of first channel is not suitably handled, from the sound of loud speaker 108 output distortions.
In this case, the user is through the mode initialization key of remote controller 114, to first channel setting, the second modulated acoustic tone signal tupe.Thus, the modulated acoustic tone signal of first channel is suitably handled, from the less high-quality sound of loud speaker 108 output distortions.
Same as described above, also can set the first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe to second channel and the 3rd channel etc.That is to say, can set the modulated acoustic tone signal tupe of the first modulated acoustic tone signal tupe or second to each channel.Therefore; No matter the modulated acoustic tone signal of each channel is the first modulated acoustic tone signal or the second modulated acoustic tone signal; Through to each channel setting first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe, thus can both be from the sound of the less high-quality of loud speaker 108 output distortions.
For example, under initial condition, control assembly (assignment component) 110 can be to each channel setting second modulated acoustic tone signal tupe.That is to say that under initial condition, memory 111 storages are to the second modulated acoustic tone signal tupe of each channel setting.
For example; In the quantity in the broadcasting station that utilizes the second modulated acoustic tone signal broadcast program country more than the quantity in the broadcasting station that utilizes the first modulated acoustic tone signal broadcast program; Under initial condition, be more convenient for during to each channel setting second modulated acoustic tone signal tupe utilizing.
Fig. 2 is the flow chart of an example that is used to explain the use difference of the first modulated acoustic tone signal tupe (Mono1) and the second modulated acoustic tone signal tupe (Mono2).
For example, in the pattern of selecting channel N and channel N being set at last (storage) (step 1 is for being) under the situation of Mono1, control assembly (assignment component) 110 setting Mono1 (step 2).Therefore, acoustic processing assembly (modulated acoustic audio processor 107) is handled the modulated acoustic tone signal of selected channel N according to Mono1.
Under the state of selecting channel N (at the state of the broadcast singal of output channel N); If Mono1 is selected (step 3) (step 4 is for being); Then control assembly (assignment component) 110 is controlled once more final store M ono1 (the final once more store M ono1 of step 5), memory 111.Therefore, then, acoustic processing assembly 107 (modulation signal processor 107) is handled the modulated acoustic tone signal of selected channel N according to Mono1.
Under the state of selecting channel N (at the state of the broadcast singal of output channel N), if Mono2 is selected (step 3) (step 4 for not), the then final store M ono2 of control assembly 110 controls (step 9), memory 111 final store M ono2.Therefore, acoustic processing assembly 107 (modulation signal processor 107) is handled the modulated acoustic tone signal of selected channel N according to Mono2.
Then, in a single day channel N is selected, then owing to the pattern of channel N being set at last (storage) is Mono2 (step 1 is for denying), so control assembly (assignment component) 110 is set Mono2 (step 6).Therefore, acoustic processing assembly 107 (modulation signal processor 107) is handled the modulated acoustic tone signal of selected channel N according to Mono2.
Under the state of selecting channel N (at the state of the broadcast singal of output channel N); If Mono2 is selected (step 7) (step 8 is for being); Then control assembly (assignment component) 110 is controlled once more final store M ono2 (the final once more store M ono2 of step 9), memory 111.Therefore, then, acoustic processing assembly 107 (modulation signal processor 107) is handled the modulated acoustic tone signal of selected channel N according to Mono2.
Under the state of selecting channel N (at the state of the broadcast singal of output channel N), if Mono1 is selected (step 7) (step 8 for not), the then final store M ono1 of control assembly (assignment component) 110 controls (step 5), memory 111 final store M ono1.Therefore, acoustic processing assembly 107 (modulation signal processor 107) is handled the modulated acoustic tone signal of selected channel N according to Mono1.
Under the situation that acoustic processing assembly 107 (modulation signal processor 107) is handled the ovennodulation voice signal according to Mono1, the sound or the noise that can an output part be interrupted from loud speaker 108 sometimes.Mono2 is the sound signal processing pattern that is suitable for the processing of ovennodulation voice signal.Therefore, under the situation that acoustic processing assembly 107 (modulation signal processor 107) is handled the ovennodulation voice signal according to Mono2, from the sound of loud speaker 108 output acoustical sounds.
With reference to Fig. 3 the modulated acoustic tone signal of carrying out according to the first modulated acoustic tone signal tupe (Mono1) and the second modulated acoustic tone signal tupe (Mono2) and the processing of ovennodulation voice signal are remarked additionally.Fig. 3 is that an illustration of the processing of expression modulated acoustic tone signal of carrying out according to the first modulated acoustic tone signal tupe (Mono1) and the second modulated acoustic tone signal tupe (Mono2) and ovennodulation voice signal is intended to.
When wanting according to Mono1 processing ovennodulation voice signal S2, signal component S21, the S22 of ovennodulation voice signal S2 can break away from process object.Therefore, can't suitably handle ovennodulation voice signal S2 with Mono1.
And, when wanting, cause the signal component S11 of modulated acoustic tone signal S1, S12 (noise contribution) can be included in the process object according to Mono2 processing modulated acoustic tone signal S1, voice output produces distortion.Therefore, can't suitably handle modulation voice signal S1 with Mono2.
That is to say, through handling modulated acoustic tone signal S1 according to Mono1, thereby can suitably handle modulated acoustic tone signal S1, and the sound of exportable good tonequality.And, through handling ovennodulation voice signal S2 according to Mono2, thereby ovennodulation voice signal S2 can be suitably handled, and the sound of good tonequality can be exported.
The broadcast receiver of above-mentioned explanation can be directed against each channel setting and store M ono1 or Mono2.Therefore, along with user's switching channels, broadcast receiver is according to being handled the modulated acoustic tone signal of the channel that is switched by the Mono1 of the channel setting that switched or Mono2.That is to say that the user need not when each switching channels, to set Mono1 or Mono2, convenience is remarkable.
And,, then can set the Mono2 of processing of the ovennodulation voice signal of the modulation degree that is suitable for distinguishing in advance if be prerequisite with the modulation degree of distinguishing the ovennodulation voice signal in advance.For example; Analyze when considering to receive signal at every turn and be comprised in the ovennodulation voice signal that receives in the signal; And under the situation of the acoustic processing pattern of the analysis result of set basis ovennodulation voice signal adjustment; According to variation that receives signal and signal analysis error etc., the acoustic processing pattern that sets changes.That is to say,, change because handle the acoustic processing pattern of this ovennodulation voice signal, so cause the voice output result also to change although the modulation degree of ovennodulation voice signal is fixed.
To this, broadcast receiver can come the ovennodulation voice signal is handled with the Mono2 of the processing of the ovennodulation voice signal of the modulation degree that is suitable for distinguishing in advance, thereby can stably handle the ovennodulation voice signal.That is to say, can access stable and good sound output result.
In addition; Be directed against each channel setting and store the example of any pattern in two modulated acoustic tone signal tupes (Mono1/Mono2) though broadcast receiver has been described in above-mentioned explanation, any pattern in the modulated acoustic tone signal tupe more than three also can set and store to broadcast receiver.
That is to say; When the 3rd modulated acoustic tone signal of second modulated acoustic tone signal of having distinguished the first modulated acoustic tone signal that there is first modulation degree, second modulation degree and the 3rd modulation degree; The broadcast receiver storage can be managed the first modulated acoustic tone signal tupe of the first modulated acoustic tone signal, the 3rd modulated acoustic tone signal tupe that can suitably handle the second modulated acoustic tone signal tupe of the second modulated acoustic tone signal and can suitably handle the 3rd modulated acoustic tone signal by appropriate location, and can and store any pattern in the first modulated acoustic tone signal tupe, the second modulated acoustic tone signal tupe and the 3rd modulated acoustic tone signal tupe to each channel setting.
And, though the advantage to each channel setting second modulated acoustic tone signal tupe has been described in above-mentioned explanation under initial condition.As stated; Under initial condition; During to each channel setting second modulated acoustic tone signal tupe; After setting, for example the user can change to the first modulated acoustic tone signal tupe with the second modulated acoustic tone signal tupe to each channel initial setting through the mode initialization key of remote controller 114.
Perhaps, acoustic processing assembly 107 (modulation signal processor 107) can be analyzed the modulated acoustic tone signal, and control assembly (assignment component) 110 can be set the first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe based on the signal analysis result.For example, select channel N, based on the analysis result of the modulated acoustic tone signal of channel N, control assembly (assignment component) 110 judges that the modulated acoustic tone signal of channel N meets the first modulated acoustic tone signal, then sets the first modulated acoustic tone signal tupe to channel N.And, if control assembly (assignment component) 110 judges that the modulated acoustic tone signal of channel N meets the second modulated acoustic tone signal, then sets the second modulated acoustic tone signal tupe to channel N.Thus, need not the modulated acoustic tone signal tupe of user to each channel setting first modulated acoustic tone signal tupe or second, also can be automatically to each the channel setting first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe.
(second execution mode)
Though explained in the first embodiment when selecting channel, to first mode initialization of the selected channel setting first modulated acoustic tone signal tupe (Mono1) or the second modulated acoustic tone signal tupe (Mono2).In second execution mode, for setting picture, second mode initialization of each the channel setting first modulated acoustic tone signal tupe (Mono1) or the second modulated acoustic tone signal tupe (Mono2) is described through signal processing model as shown in Figure 4.
For example, the user can set picture through the Menu key indicated number signal processing model of remote controller 114.The demonstration that the control assembly of broadcast receiver (assignment component) 110 set picture according to signal processing model is indicated, and the control signal tupe is set the demonstration of picture.Therefore, image display part (output precision) 106 shows signal processing model setting picture as shown in Figure 4.That is to say that image display part (output precision) 106 outputs are used for the display message that the shows signal tupe is set picture.
If the user is through directionkeys and definite key of remote controller 114 (signal processing model selector); Indication is set Mono1 to channel 101 on signal processing model setting picture; Then control assembly (assignment component) 110 is controlled so that set Mono1 to channel 101, and memory 111 is to channel 101 store M ono1.
Perhaps; If the user is through directionkeys and definite key of remote controller 114 (signal processing model selector); Indication is set Mono2 to channel 101 on signal processing model setting picture; Then control assembly (assignment component) 110 is controlled so that channel 101 is set Mono2, and memory 111 is to channel 102 store M ono2.
Equally, also can set Mono1 or Mono2 for channel 102,103 etc., memory 111 is to channel 102,103 etc. also store M ono1 or Mono2.
And, also can set the content of picture affirmation through signal processing model as shown in Figure 3 through setting at first mode initialization of first execution mode explanation.That is to say; If the user is through the demonstration of the Menu key index signal tupe setting picture of remote controller 114, then image display part (output precision) 106 shows signal processing model setting picture (set condition of current signal processing model) as shown in Figure 4.
According to aforesaid at least one execution mode; Can provide according to signal processing model and come treatment of selected to select the modulation signal of channel, thereby can tackle the modulation signal processing unit and the modulation signal processing method of ovennodulation signal well selected channel setting.
In addition, said modules also can be through hard-wired assembly, the assembly that can also be to use CPU etc. to realize with software.
Although clear several embodiments of the present invention, but these execution modes just illustrate as an example, do not limit scope of invention.These new execution modes can be enough other various modes implement, as long as in the scope of the main points that do not break away from invention, can carry out various omissions, replacement, change.These execution modes and distortion thereof all are included in scope of invention and the main points, are included in simultaneously in the invention put down in writing in protection scope of the present invention and the scope equal with it.
