The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic flow chart of a digital television signal processing method according to an embodiment of the present application, and as shown in the drawing, the digital television signal processing method is applied to a television, and includes:
101. a first television signal is acquired.
In this embodiment of the present application, the television may include a plurality of ports for one or more other devices (audio devices or earphones) to access, the audio devices may be wireless or wired audio devices, the earphones may be wired or wireless earphones, the television may include a human interface, and the human interface may include, but is not limited to: a television remote control, a voice receiving module (e.g., a microphone), a sensor, a video receiving module, a touch screen, a keyboard, buttons, knobs, a projection interface, a virtual 3D interface, and the like, without limitation. The user can realize various control operations aiming at the television through a manual interaction mode, and the manual interaction mode can be at least one of the following modes: the user may also click the screen to select a certain option when the manual interaction interface is a touch screen, through a remote controller key, a voice command, through different gestures or actions of the user, eye movement, head movement, or the like, and the like, which is not limited herein.
102. The first television signal is separated into an image signal and a first audio signal.
In a specific implementation, the television may implement audio and video separation, that is, perform signal separation on the first television signal, and may obtain an image signal and a first audio signal.
103. Hearing status data of a target user is acquired.
The hearing ability status data of the target user may be stored in a memory of the television in advance, or the hearing ability status data may also be stored in a cloud (cloud server).
In one possible example, the step 103 of acquiring the hearing status data of the target user may be implemented as follows:
and acquiring the hearing status data of the target user in a man-machine interaction mode.
In specific implementation, the television can guide a target user to acquire the hearing status data of the target user in a man-machine interaction mode.
For example, the method for acquiring the hearing data of the target user by the television may be to complete the test by the local audio playing device and acquiring the feedback of the user, or may be to directly acquire the hearing status data by connecting to the cloud server (for example, the result of the evaluation elsewhere by the target user, or the result of the previous test).
In one possible example, the above step of obtaining the hearing status data of the target user through a human-computer interaction mode may include the following steps S1-S3:
s1, playing a preset audio signal;
s2, obtaining feedback data of the target user for the preset audio signal, adjusting the preset audio signal according to the feedback data, detecting whether the preset audio signal meets a preset condition, if so, executing a step S3, and if not, executing a step S1 according to the adjusted preset audio signal;
and S3, sorting the feedback data, and determining the hearing status data according to the sorted feedback data.
The preset audio signal is a test audio signal, different age groups can correspond to different test audio signals, the preset audio signal can be stored in a memory of the television, the preset audio signal can also be generated in real time according to feedback data of a user, a preset condition can be set by the user or default by a system, for example, the preset condition is that the preset audio signal covers a preset test audio range, or the preset condition is determined by the feedback data of the user, for example, the feedback data is normal. The hearing status data may be stored locally or in the cloud.
In a specific implementation, the television may play a segment of audio used for detecting the hearing ability of the user through the currently connected playing module (which may be the audio output of the television itself or an earphone or a speaker connected to the user) through the television audio channel. For example, when a pure tone auditory field test is performed, a sine wave pure tone with a preset fixed frequency can be played; for another example, when performing a noise masking test, white noise or gaussian noise can be played before/simultaneously with/after a certain signal; for another example, when speech intelligibility audiometry is performed, a section of speech can be played; when the pure tone attenuation test is carried out, the pure tone audio with the duration exceeding 1min can be played. The test audio and the flow of each time can be stored in an internal memory of the television and can also be acquired by connecting a cloud server.
Further, the tv may obtain the user's reaction to the audio signal through the human-computer interface, and the user's feedback may include open or closed answers, such as: giving an answer according to the heard content, or selecting a certain option according to the heard content; depending on whether the content heard is comfortable, a certain answer is selected, the user's options and the answer being used as feedback data.
Furthermore, the television can dynamically adjust the testing process and the output preset audio signal according to the feedback data, for example, a pure tone can be played after a small section of white noise or narrow-band noise is played (0.001-10s), when the user feedback can hear the volume of a larger test tone (e.g. pure tone, voice, etc.) (70dB), the testing program can play the volume with gradient reduction (65dB) until the user feedback answers to the sound; otherwise, the volume is continuously increased from the lower volume (0dB) until the user feedback is audible. The descending/ascending gradient may be constant or may vary in different gradients. In addition to the gradient change, to shorten the testing time, a threshold value that is just audible to the user can be located by using a binary search method and the like. Further, the initial volume may also be dynamically changed based on the previous feedback from the user to shorten the test duration.
104. And processing the first audio signal according to the hearing status data to obtain a second audio signal.
In the embodiment of the application, the hearing status data reflects the hearing condition of the user, and for the hearing condition of the user, the television can perform personalized compensation on the first audio signal to obtain the second audio signal, and the second audio signal can meet the personalized requirement of the user.
In one possible example, the hearing condition data includes a hearing impairment curve, and the step 104 of processing the first audio signal according to the hearing condition data to obtain a second audio signal may include the steps of:
41. determining a target damage interval of the target user according to the hearing damage curve;
42. determining a target compensation parameter corresponding to the target damage interval according to a mapping relation between a preset interval and the hearing compensation parameter;
43. determining an audio signal to be compensated corresponding to the target damage interval in the first audio signal;
44. compensating the audio signal to be compensated according to the target compensation parameter to obtain a compensated audio signal;
45. determining an uncompensated audio signal and the compensated audio signal of the first audio signal as the second audio signal.
In the embodiment of the present application, the compensation parameter may be at least one of: the compensation algorithm, the compensation adjustment parameter, the compensation frequency band, the compensation duration and the mapping relation between the preset interval and the hearing compensation parameter can be prestored in a memory of the compensation television, the hearing status data can comprise a hearing impairment curve, the horizontal axis of the hearing impairment curve can be frequency, the vertical axis of the hearing impairment curve can be amplitude, and the audio signal can be processed according to the obtained hearing status of the user. For example, a hearing impairment curve can be drawn according to the hearing loss of the user in different frequency bands, and the corresponding relation (target frequency response function) of the input/output on the frequency spectrum, which is required by the system to satisfy the requirement of each user for achieving the intelligibility of the preset target language or the normalization of the loudness, can be calculated according to the corresponding normal population reference curve.
Specifically, the television can determine a target damage interval of a target user according to a hearing damage curve, that is, a hearing limited area or an area with poor experience of the user, and determine a target compensation parameter corresponding to the target damage interval according to a mapping relationship between a preset interval and the hearing compensation parameter, further, determine an audio signal to be compensated in the first audio signal, which corresponds to the target damage interval, and compensate the audio signal to be compensated according to the target compensation parameter to obtain a compensated audio signal, and finally determine an uncompensated audio signal and the compensated audio signal in the first audio signal as a second audio signal.
In a specific implementation, the television can perform corresponding processing on the input audio by calculating a target frequency response function (compensation parameter) of the signal processing system, so as to meet personalized requirements of users for listening to the television audio, such as targeted compensation for audio signals of different frequency bands. For example, the compensation parameter may be a time domain convolution function, and convolution operation may be performed on a time domain signal by calculating the time domain convolution function, or for example, the compensation parameter may be a filter bank through which compensation is implemented; for another example, the compensation parameter may be framing, the signal may be framed, a short-time frequency domain signal is obtained through fast fourier transform, a spectral coefficient is amplified or reduced (determined by a specific actual situation), a time domain signal is obtained through inverse fourier transform, and a continuous time domain audio signal is obtained again by superimposing the framed signal.
105. And calibrating the second audio signal to obtain a third audio signal.
In specific implementation, the television may calibrate the second audio signal to obtain a third audio signal, and specifically, may fine-tune the processing effect by obtaining feedback of the processed audio signal. Whether the step is added or not can be selected in actual implementation, and due to the fact that different users have respective hearing preferences and the left ear and the right ear are in balance, the actual hearing compensation effect needs to be finely adjusted according to the feedback of the users. This adjustment may be based on feedback from the user under the current interactive interface, or based on user data obtained by the cloud server.
In a possible example, between the above steps 104 to 105, the following steps may be further included:
performing dynamic volume compression on the second audio signal to obtain a compressed second audio signal;
then, in the above step 105, the second audio signal is calibrated to obtain a third audio signal, which can be implemented as follows:
and calibrating the compressed second audio signal to obtain the third audio signal.
In a specific implementation, because the hearing loss population is smaller than that of a general person in hearing range, and the audio signal needs to have different degrees of gain or reduction at different sound pressure levels, the processed signal needs to be subjected to dynamic volume compression. For example, in the compression curve, low energy corresponds to high gain and high energy corresponds to low gain. After the hearing threshold and the uncomfortable domain of the user are obtained, personalized dynamic compression can be carried out according to the obtained hearing data. Dynamic compression may be performed in the time domain or in any transform domain (e.g., fourier transform, discrete cosine transform, discrete wavelet transform).
106. And synchronizing the third audio signal and the image signal to obtain a second television signal.
In a specific implementation, the television may synchronize the third audio signal and the image signal, and a main consideration of the synchronization may be processing delay of the processing system itself. For example, time stamps can be added to the audio/video signals, or a watermark signal can be embedded into the audio/video data stream before processing.
107. Outputting the second television signal to the target user.
In a specific implementation, the television may play the audio signal through an audio output module of the television, and simultaneously play the synchronized video signal through a video output module of the television. The output module of the audio signal can be replaced by a Bluetooth transmitting module, an audio amplifying module, an audio processing module and the like, and the equipment connected with the television can be earphones or sound equipment. The video output module may be replaced by a video processing module, a projector device, a display device, or the like.
It can be seen that the digital television signal processing method described in the embodiment of the present application is applied to a television, and the television may obtain a first television signal, separate the first television signal into an image signal and a first audio signal, obtain hearing status data of a target user, process the first audio signal according to the hearing status data to obtain a second audio signal, calibrate the second audio signal to obtain a third audio signal, synchronize the third audio signal with the image signal to obtain a second television signal, output the second television signal to the target user, compensate the television signal according to the hearing status of the user, optimize hearing experience of different users, and protect hearing.

Wherein figure 3 is a schematic diagram of the system interacting with the outside world. Fig. 4 shows a schematic diagram of the internal structure of a sample system.
As shown in fig. 3, the system 3100 may be disposed inside a television, and the system may acquire hearing status data of a user (e.g., hearing information, hearing mode selected by the user, user feedback, etc.) through a human-computer interaction 3300 with the user 3200, and at the same time, the system may also perform data exchange 3500 with a cloud Server (Server)3400 to acquire user information, and may implement switching of the hearing mode required by the user according to a part of information, and the system may output one or more different sets of audio signals 3600 and one set of video signals 3700. The output audio 3600 may comprise one or more sets of differently processed (or unprocessed original) audio streams, depending on the different hearing modes switched at step 3300/3500.
For example, when the device is in the "home mode", a set of audio modulated according to the hearing ability of the elderly at home can be output to the earphone for the elderly to use, and meanwhile, the original audio which is not processed normally is output to the television speaker module, so that the family and the elderly can watch television together. And when in the private mode, only one path of audio (modulated according to the hearing condition of the current user) can be output to the audio output module (including but not limited to using earphones, a sound box, a built-in television speaker and the like) for playing. When in the "share mode" and the television supports multiple outputs, audio streams adapted to the respective hearing conditions of each user may also be output according to the different interfaces used by the different users.
