The modulation sound signal processing of then, the broadcast receiver by above-mentioned explanation being carried out describes.
(the first execution mode)
In some countries, sometimes broadcast the ovennodulation voice signal (the second modulated acoustic tone signal) with modulation degree (the second modulation degree) modulation with different from specified modulation degree with the modulated acoustic tone signal (the first modulated acoustic tone signal) of specified modulation degree (the first modulation degree) modulation.
The control assembly (assignment component) 110 of broadcast receiver can be a modulated acoustic tone signal tupe (signal processing model) of selecting from multiple modulated acoustic tone signal tupes (multiple signal processing model) for each channel setting, and storage is for the modulated acoustic tone signal tupe (signal processing model) of each channel setting.For example, memory 111 is stored multiple modulated acoustic tone signal tupes, and further stores the modulated acoustic tone signal tupe for each channel setting.
Thus, the acoustic processing assembly 107 (modulation signal processor 107) of broadcast receiver can be with reference to the modulated acoustic tone signal tupe that is stored in the each channel in memory 111, and according to the modulated acoustic tone signal tupe (signal processing model) for selected channel setting, the modulated acoustic tone signal (modulation signal) of the channel that treatment of selected is selected.
For example, if user indicates the selection of the first channel by the first channel key of remote controller 114, corresponding, the first broadcast singal of the first channel is selected and exported to tuner (channel selector) 102 from receiving broadcast signal, image processing component 104 processes and output packet is contained in the signal of video signal in the first broadcast singal, acoustic processing assembly 107 (modulation signal processor 107) is according to the first modulated acoustic tone signal tupe for the first channel setting or the second modulated acoustic tone signal tupe, process also output packet and be contained in the voice signal in the first broadcast singal.Then, the image that image display portion (output precision) 106 shows based on being included in the signal of video signal in the first broadcast singal, loud speaker 108 is exported the sound based on being included in the voice signal in the first broadcast singal.
The first modulated acoustic tone signal tupe is the pattern for the treatment of the first modulated acoustic tone signal with the first modulation degree modulation.For example, the first modulated acoustic tone signal tupe is the pattern for process modulated acoustic tone signal in the situation that not proofreading and correct modulated acoustic tone signal.And the second modulated acoustic tone signal tupe is the pattern for the treatment of the second modulated acoustic tone signal with the second modulation degree modulation.For example, the second modulated acoustic tone signal tupe is for proofreading and correct the pattern of after modulated acoustic tone signal, modulation voice signal being processed.
As mentioned above, selecting under the state of the first channel (having the state of the first broadcast singal of the first channel in output), user, by the pattern setting key of remote controller 114, can change the first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe for the first channel setting.
For example, selecting under the state of the first channel and the state for first channel setting the first modulated acoustic tone signal tupe, if press the pattern setting key of remote controller 114,110 pairs of first channel setting the second modulated acoustic tone signal tupes of control assembly (assignment component), memory 111 is stored the second modulated acoustic tone signal tupe for the first channel setting.
In addition, at the state of selection the first channel and under to the state of first channel setting the second modulated acoustic tone signal tupe, if press the pattern setting key of remote controller 114,110 pairs of first channel setting the first modulated acoustic tone signal tupes of control assembly (assignment component), memory 111 is stored the first modulated acoustic tone signal tupe for the first channel setting.
For example, the first modulated acoustic tone signal with the first modulation degree modulation in the modulated acoustic tone signal of the first channel, if to first channel setting the first modulated acoustic tone signal tupe, the modulated acoustic tone signal of the first channel is suitably processed, from the less high-quality sound of loud speaker 108 output distortions.
On the contrary, the second modulated acoustic tone signal with the second modulation degree modulation in the modulated acoustic tone signal of the first channel, if to first channel setting the first modulated acoustic tone signal tupe, the modulated acoustic tone signal of the first channel is not suitably processed, from the sound of loud speaker 108 output distortions.
In this case, user is by the pattern setting key of remote controller 114, to first channel setting the second modulated acoustic tone signal tupe.Thus, the modulated acoustic tone signal of the first channel is suitably processed, 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 the 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, by to each channel setting the 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 distortion.
For example, under initial condition, control assembly (assignment component) 110 can be to each channel setting the second modulated acoustic tone signal tupe.That is to say, under initial condition, memory 111 is stored the second modulated acoustic tone signal tupe to each channel setting.
For example, utilizing the quantity in broadcasting station of the second modulated acoustic tone signal broadcast program more than the country of quantity in broadcasting station that utilizes the first modulated acoustic tone signal broadcast program, under initial condition, during to each channel setting the second modulated acoustic tone signal tupe, be more convenient for utilizing.
Fig. 2 is the flow chart of an example of the use difference for the first modulated acoustic tone signal tupe (Mono1) and the second modulated acoustic tone signal tupe (Mono2) are described.
For example,, in the case of selecting channel N and be (step 1 is yes) Mono1 to the pattern that channel N finally sets (storage), control assembly (assignment component) 110 setting Mono1 (step 2).Therefore, acoustic processing assembly (modulated acoustic audio processor 107) is processed the modulated acoustic tone signal of selected channel N according to Mono1.
Selecting under the state of channel N (at the state of the broadcast singal of output channel N), if Mono1 is selected (step 3) (step 4 is yes), control assembly (assignment component) 110 is controlled again final store M ono1 (step 5), and memory 111 is final store M ono1 again.Therefore, then, acoustic processing assembly 107 (modulation signal processor 107) is processed the modulated acoustic tone signal of selected channel N according to Mono1.
Selecting under the state of channel N (at the state of the broadcast singal of output channel N), if Mono2 is selected (step 3) (step 4 is no), control assembly 110 is controlled final store M ono2 (step 9), the final store M ono2 of memory 111.Therefore, acoustic processing assembly 107 (modulation signal processor 107), according to Mono2, is processed the modulated acoustic tone signal of selected channel N.
Then, once channel N is selected, because the pattern of (storage) that channel N is finally set is Mono2 (step 1 is no), so control assembly (assignment component) 110 is set Mono2 (step 6).Therefore, acoustic processing assembly 107 (modulation signal processor 107), according to Mono2, is processed the modulated acoustic tone signal of selected channel N.
Selecting under the state of channel N (at the state of the broadcast singal of output channel N), if Mono2 is selected (step 7) (step 8 is yes), control assembly (assignment component) 110 is controlled again final store M ono2 (step 9), and memory 111 is final store M ono2 again.Therefore, then, acoustic processing assembly 107 (modulation signal processor 107) is processed the modulated acoustic tone signal of selected channel N according to Mono2.
Selecting under the state of channel N (at the state of the broadcast singal of output channel N), if Mono1 is selected (step 7) (step 8 is no), control assembly (assignment component) 110 is controlled final store M ono1 (step 5), the final store M ono1 of memory 111.Therefore, acoustic processing assembly 107 (modulation signal processor 107) is processed the modulated acoustic tone signal of selected channel N according to Mono1.
In the situation that acoustic processing assembly 107 (modulation signal processor 107) is processed ovennodulation voice signal according to Mono1, sometimes can a part of sound or the noise being interrupted of output from loud speaker 108.Mono2 is the sound signal processing pattern that is suitable for the processing of ovennodulation voice signal.Therefore,, in the situation that acoustic processing assembly 107 (modulation signal processor 107) is processed ovennodulation voice signal according to Mono2, export the sound of acoustical sound from loud speaker 108.
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 be represent 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 ovennodulation voice signal processing one illustrate intention.
In the time wanting to process ovennodulation voice signal S2 according to Mono1, signal component S21, the S22 of ovennodulation voice signal S2 can depart from handling object.Therefore, cannot suitably process ovennodulation voice signal S2 with Mono1.
And, in the time wanting to process modulated acoustic tone signal S1 according to Mono2, cause signal component S11, the S12 (noise contribution) of modulated acoustic tone signal S1 can be included in handling object, voice output produces distortion.Therefore, cannot suitably process modulation voice signal S1 with Mono2.
That is to say, by process modulated acoustic tone signal S1 according to Mono1, thereby can suitably process modulated acoustic tone signal S1, and the sound of exportable good tonequality.And, by process ovennodulation voice signal S2 according to Mono2, thereby ovennodulation voice signal S2 can be suitably processed, and the sound of good tonequality can be exported.
The broadcast receiver of above-mentioned explanation can be for each channel setting store M ono1 or Mono2.Therefore,, along with user's switching channels, broadcast receiver is processed the modulated acoustic tone signal of the channel being switched according to the Mono1 to the channel setting being switched or Mono2.That is to say, user is without setting Mono1 or Mono2, convenience brilliance when each switching channels.
And, if taking the modulation degree of distinguishing in advance ovennodulation voice signal as prerequisite, can set the Mono2 of the processing of the ovennodulation voice signal of the modulation degree that is suitable for distinguishing in advance.For example, while considering each reception signal, analyze and be comprised in the ovennodulation voice signal receiving in signal, and set in the situation of the acoustic processing pattern of adjusting according to the analysis result of ovennodulation voice signal, according to the variation and the signal analysis error etc. that receive signal, the acoustic processing pattern setting changes.That is to say, although the modulation degree of ovennodulation voice signal is fixed, change because process the acoustic processing pattern of this ovennodulation voice signal, so cause voice output result also to change.
To this, broadcast receiver can be processed ovennodulation voice signal 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 process ovennodulation voice signal.That is to say, can obtain stable and good voice output result.
In addition, although broadcast receiver be described in the above description for each channel setting and stored the example of any pattern in two modulated acoustic tone signal tupes (Mono1/Mono2), three any patterns in above modulated acoustic tone signal tupe also can be set and store to broadcast receiver.
That is to say, when having distinguished the first modulated acoustic tone signal that has the first modulation degree, the second modulated acoustic tone signal of the second modulation degree, and when the 3rd the 3rd modulated acoustic tone signal of modulation degree, the first modulated acoustic tone signal tupe of the first modulated acoustic tone signal can be suitably processed in broadcast receiver storage, can suitably process the second modulated acoustic tone signal tupe of the second modulated acoustic tone signal, and can suitably process the 3rd modulated acoustic tone signal tupe of the 3rd modulated acoustic tone signal, and can and store the first modulated acoustic tone signal tupe for each channel setting, any pattern in the second modulated acoustic tone signal tupe and the 3rd modulated acoustic tone signal tupe.
And, although the advantage to each channel setting the second modulated acoustic tone signal tupe under initial condition has been described in the above description.As mentioned above, under initial condition, during for each channel setting the second modulated acoustic tone signal tupe, after setting, for example user, by the pattern setting key of remote controller 114, can change to the first modulated acoustic tone signal tupe by the second modulated acoustic tone signal tupe to each channel initial setting.
Or, acoustic processing assembly 107 (modulation signal processor 107) can be analyzed 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 signal analysis result.For example, select channel N, the analysis result of the modulated acoustic tone signal based on channel N, control assembly (assignment component) 110 judges that the modulated acoustic tone signal of channel N meets the first modulated acoustic tone signal, channel N is set to the first modulated acoustic tone signal tupe.And, if judging the modulated acoustic tone signal of channel N, control assembly (assignment component) 110 meets the second modulated acoustic tone signal, channel N is set to the second modulated acoustic tone signal tupe.Thus, the modulated acoustic tone signal tupe without user to each channel setting the first modulated acoustic tone signal tupe or second, also can be automatically to each channel setting the first modulated acoustic tone signal tupe or the second modulated acoustic tone signal tupe.
(the second execution mode)
Although illustrated in the first embodiment in the time selecting channel, the first mode of selected channel setting the first modulated acoustic tone signal tupe (Mono1) or the second modulated acoustic tone signal tupe (Mono2) set.In the second execution mode, set picture for the signal processing model by as shown in Figure 4, the second pattern of each channel setting the first modulated acoustic tone signal tupe (Mono1) or the second modulated acoustic tone signal tupe (Mono2) is set and described.
For example, user can set picture by the Menu key indicated number signal processing model of remote controller 114.Control assembly (assignment component) 110 of broadcast receiver set the demonstration instruction of picture according to signal processing model, control signal tupe is set the demonstration of picture.Therefore, image display portion (output precision) 106 shows signal processing model setting picture as shown in Figure 4.That is to say, the demonstration information of picture is set in image display portion (output precision) 106 outputs for display tupe.
If user is by directionkeys and definite key of remote controller 114 (signal processing model selector), set instruction on picture at signal processing model channel 101 is set to Mono1, control assembly (assignment component) 110 is controlled to set Mono1 for channel 101, and memory 111 is for channel 101 store M ono1.
Or, if user is by directionkeys and definite key of remote controller 114 (signal processing model selector), set instruction on picture at signal processing model channel 101 is set to Mono2, control assembly (assignment component) 110 is controlled to channel 101 is set to Mono2, and memory 111 is for channel 102 store M ono2.
Equally, also can set Mono1 or Mono2 for channel 102,103 etc., memory 111 is for channel 102,103 etc. also store M ono1 or Mono2.
And, also can set picture by signal processing model as shown in Figure 3 and confirm the content by setting at the first mode of the first execution mode explanation.That is to say, if user sets the demonstration of picture by the Menu key index signal tupe of remote controller 114, image display portion (output precision) 106 shows signal processing model setting picture (set condition of current signal processing model) as shown in Figure 4.
According at least one execution mode as above, can provide according to the signal processing model of selected channel setting is carried out to treatment of selected and select the modulation signal of channel, thereby can tackle well modulation signal processing unit and the modulation signal processing method of ovennodulation signal.
In addition, said modules can be also by hard-wired assembly, can also be the assembly that uses CPU etc. to realize with software.
Although the description of several execution modes 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 implemented by other various modes, as long as in the scope of main points that does not depart from invention, can carry out various omissions, replacement, change.These execution modes and distortion thereof are all included in scope of invention and main points, are included in the invention recorded in protection scope of the present invention and the scope equal with it simultaneously.
