Description

Method for adjusting television volume and digital television equipment

Technical Field

The present invention relates to communications technologies, and in particular, to a method for adjusting television volume and a digital television device.

Background

Most homes currently use set-top boxes to view television programs. The basic function of the set-top box is to receive digital television broadcasting programs; the program may be sourced from a variety of sources, such as a satellite program, a recorded program, or a program stream from another network. However, the front end of the digital television does not perform the processing of equalizing and re-encoding the volume of the programs, so that the volume of each program has a large difference due to the difference of the original program source volume. For example, when a user watches a television program, although the volume setting of the set-top box is the same value for each program (i.e., the set-top box volume parameter value set by the set-top box remote controller is fixed), the volume of each program is found to be different when the channel is switched, and even when the television stays in the same channel, the volume may be significantly changed due to the change of the program, which affects the watching experience of the user.

In order to avoid the above problems, the prior art adopts a volume compensation technology, that is, the front end of the digital television sends a program stream to the set-top box, wherein the program stream carries programs and a program information table; the digital television front end can send down a private descriptor of volume compensation in a program information table of a program stream sent to the set top box by judging the volume of each program; when the set-top box receives the program stream, the volume compensation descriptor in the program information table is analyzed, and then the analyzed volume compensation value is superposed with the local volume setting to serve as a final volume output value, so that the purpose of adjusting the program volume is achieved.

However, the program volume adjusted by the prior art still cannot meet the requirement of the user on the television program volume, and the human-computer interaction is not intelligent enough.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminal according to the embodiment of the present invention may include, but is not limited to, a mobile communication device such as a mobile phone, a Personal Digital Assistant (PDA), a tablet computer, and a portable device (e.g., a portable computer).

The digital television device according to the embodiment of the present invention may include a digital set-top box, a digital television, and may further include a digital television front-end server, and in different scenes, the contents included in the digital television device are different, which may be specifically referred to the description of the following embodiments. In practical application, the digital set top box is connected with the digital front-end server in a wireless or wired mode, the digital television front-end server can issue a program and a program information table to the digital set top box in a streaming mode, and then the digital set top box analyzes the data stream to obtain the program and the program information table; because the digital set-top box is connected with the television by a video and audio cable, the set-top box can output the obtained programs and the program information table to the television in the form of video and audio signals for displaying.

The method provided by the embodiment of the invention aims to solve the technical problems that the program volume adjusted by the prior art can not meet the requirement of a user on the television program volume and the man-machine interaction is not intelligent enough.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1 is a schematic flowchart of a first embodiment of a method for adjusting television volume according to an embodiment of the present invention. The embodiment relates to a specific process that the digital television equipment adjusts the sound intensity to meet the sound intensity required by a user through the sound intensity obtained from a terminal when a television plays a program. As shown in fig. 1, the method includes:

s101: the digital television equipment receives first sound intensity of audio and video played by a television, which is detected by a terminal.

Specifically, when a user opens the television, the television is playing the audio and video of the program at the moment, and the terminal monitors the sound emitted by the television to obtain the first sound intensity of the audio and video played by the television. Optionally, the terminal may be any device having a function of detecting the intensity of sound, that is, the device not only needs to have a sound receiving function, but also needs to have a function of detecting the intensity of the recorded sound. The terminal and the digital television device may be in communication connection in a Wireless connection manner, for example, the terminal and the digital television device may be connected in a communication manner that may be used to transmit a Wireless signal, such as Wireless Fidelity (WIFI), infrared, bluetooth, General Packet Radio Service (GPRS) and the like. Taking a mobile phone as an example, when a television plays the audio and video of a program, the mobile phone can start the software for detecting the sound intensity and the radio microphone which are arranged in the mobile phone to monitor the sound intensity of the audio and video of the television playing program. The terminal can also be a common remote controller, and only a sound receiving microphone and software for detecting the sound intensity need to be added to the remote controller. It should be noted that the radio device on the terminal may be a radio microphone, or may be another radio hardware module, as long as the module has a radio function; in addition, when the terminal detects the sound intensity, the sound intensity can be detected not only by starting software for detecting the sound intensity on the terminal, but also by building a hardware module capable of detecting the sound intensity on the terminal, or by combining software and hardware. The embodiment of the invention does not limit how the terminal receives the sound and how the terminal detects the sound intensity.

Here, the mobile phone is taken as an example to explain how the terminal detects the sound intensity of the acquired television. The MIC on the mobile phone can be used for receiving sound emitted by the television, and the waveform of the sound can be obtained by any mobile phone of the system (for example, a mobile phone of an android system, a mobile phone of an apple system). The decibel value of the sound can be converted according to the sampling rate of the mobile phone itself to the sound, for example, the sampling rate of the sound card is 11.025kHz, i.e., 11025 times per second, and the quantization value of each sampling is represented by a value between 0 and 65536. This results in a discrete signal of the sound in the time domain. Discrete signals of sound in a frequency domain range can be obtained by performing discrete Fourier transform on the discrete signals, after the discrete signals are divided into octaves, the average value of frequency points in each frequency band is calculated, then logarithm is taken, and decibel values of each frequency band can be obtained. And finally, weighting the obtained logarithm value according to the A-rate curve to obtain a final sound decibel value, namely the first sound intensity.

S102: the digital television equipment determines a second sound intensity according to the first sound intensity and a preset sound intensity threshold range [ M, N ]; wherein M and N are both natural numbers greater than 0, and M is less than N; the preset sound intensity threshold range is a sound intensity threshold range suitable for a user to listen.

Specifically, the terminal sends the obtained first sound intensity to the digital television device, so that the digital television device can determine the second sound intensity according to the relationship between the first sound intensity and the preset sound intensity threshold range [ M, N ]. Optionally, the second sound intensity may be determined according to the determination result by directly determining whether the first sound intensity is within the preset sound intensity threshold range [ M, N ], or may be determined according to the matching result by determining whether the first sound intensity is matched with a sound intensity value within the preset sound intensity range, or may be determined according to the determination result by determining the magnitude of the endpoint value of the first sound intensity and the preset sound intensity range. The preset sound intensity threshold range [ M, N ] may be a sound intensity range suitable for human ear listening set by a user, for example, 40dB to 70dB, or a sound intensity range suitable for human ear listening saved by a terminal according to a use habit of the user, for example, 50dB to 60 dB. Optionally, the second sound intensity may be the same as or different from the first sound intensity, depending on the determination result. For example, if the digital television apparatus determines that the first sound intensity is within the preset sound intensity threshold range [ M, N ], the digital television apparatus determines that the intensity of the sound currently emitted by the television is suitable for being listened to by human ears, and then determines that the second sound intensity is equal to the first sound intensity.

S103: and the digital television equipment adjusts the sound intensity of the audio and video played by the television into the second sound intensity.

Specifically, after the digital television equipment determines the second sound intensity, the sound of the current television is automatically adjusted to the second sound intensity so as to meet the sound requirement of the user on television playing audio and video, the listening experience of the user is improved, and the human-computer interaction intelligence among the digital television equipment, the terminal and the user is further realized.

According to the method for adjusting the volume of the television, provided by the embodiment of the invention, the first sound intensity of the audio and video played by the television, which is detected by the receiving terminal of the digital television equipment, is determined, the second sound intensity is determined according to the first sound intensity and the preset threshold range [ M, N ] of the sound intensity of the audio and video played by the television, and the second sound intensity is automatically adjusted, so that the sound requirement of a user on the audio and video played by the television is met, the listening experience of the user is improved, and the human-computer interaction intelligence among the digital television equipment, the terminal and the user is further improved.

Fig. 2 is a flowchart illustrating a second embodiment of a method for adjusting television volume according to an embodiment of the present invention. The embodiment relates to a specific process how the terminal determines the second sound intensity according to the first sound intensity and a preset sound intensity threshold range [ M, N ] when the digital television device is a digital set-top box or a television. As shown in fig. 2, based on the above embodiment, the step S102 specifically includes:

s201: and the digital television equipment judges whether the first sound intensity is within the preset sound intensity threshold range [ M, N ]. If yes, executing S202; if not, go to S203.

Specifically, after receiving a first sound intensity of the television fed back by the terminal, the digital television device determines whether the first sound intensity is within the preset sound intensity threshold range [ M, N ]. Optionally, the digital television device determines whether the first sound intensity is within a preset sound intensity threshold range by determining whether the first sound intensity matches a certain sound intensity value within the preset sound intensity range; for example, if the first sound intensity matches a value of a sound intensity within the preset sound intensity range, it indicates that the first sound intensity is within the preset sound intensity threshold range (the "match" may be that the first sound intensity is equal to a value of a sound intensity within the preset sound intensity threshold range); if the first sound intensity does not match any of the sound intensity values in the preset sound intensity range, it indicates that the first sound intensity is not within the preset sound intensity threshold range. Optionally, the digital television device may further determine whether the first sound intensity is within the preset sound intensity threshold range according to a determination result by determining a size of an endpoint value of the first sound intensity and the preset sound intensity range. The embodiment of the present invention does not limit how the digital television apparatus determines whether the first sound intensity is within the preset sound intensity threshold range.

S202: the digital television apparatus determines the second sound intensity to be a value equal to the first sound intensity.

Specifically, when the digital television device determines that the first sound intensity is within the preset sound intensity threshold range, the digital television device determines that the second sound intensity is equal to the first sound intensity, that is, the digital television device determines that the sound of the current television playing program audio/video can meet the listening requirement of the user, and optionally, the digital television device can fix the sound of the television at the first sound intensity in a software or software and hardware combined manner.

S203: the digital television equipment judges the size relation between the first sound intensity and endpoint values M and N of the preset sound intensity threshold range; if the digital television equipment judges that the first sound intensity is smaller than M, the digital television equipment determines that the second sound intensity is a value which is larger than or equal to M and smaller than or equal to N; if the digital television equipment judges that the first sound intensity is larger than the N, the digital television equipment determines that the second sound intensity is a value of which M is larger than or equal to the N and is smaller than or equal to the N.

Specifically, when the digital television device determines that the first sound intensity is not within the preset sound intensity threshold range, the digital television device determines that the sound of the audio/video of the current television playing program cannot meet the listening requirement of the user, and therefore, the digital television device further determines the size relationship between the first sound intensity and the endpoint values M and N of the preset sound intensity threshold range. When the digital television equipment judges that the first sound intensity is smaller than M, the digital television equipment determines that the sound of the audio and video of the program currently played by the television is too small, and the sound of the audio and video of the program currently played by the television needs to be increased, namely the sound is increased from the first sound intensity to a second sound intensity, wherein the second sound intensity is a value which is more than or equal to the M and less than or equal to the N; when the digital television equipment judges that the first sound intensity is greater than N, the digital television equipment determines that the sound of the audio and video of the program currently played by the television is too large, and the sound of the audio and video of the program currently played by the television needs to be reduced, namely the sound is reduced from the first sound intensity to a second sound intensity, wherein the second sound intensity is a value which is greater than or equal to M and less than or equal to N. The above adjustment can make the sound of the current playing program of the television meet the listening requirement of the user.

According to the method for adjusting the volume of the television, provided by the embodiment of the invention, the first sound intensity of the audio and video played by the television, which is detected by the receiving terminal of the digital television equipment, is judged, whether the first sound intensity is within the preset sound intensity threshold range [ M, N ] or not is judged, so that the second sound intensity is determined according to the judgment result, and the sound intensity of the audio and video played by the television is adjusted to the second sound intensity, so that the sound requirement of a user on the audio and video played by the television is met, the listening experience of the user is improved, and the human-computer interaction intelligence among the digital television equipment, the terminal and the user is further improved; in addition, in this embodiment, when the digital television device is a digital set-top box, the method of this embodiment is adopted, and the digital set-top box is not required to process the private descriptor, so that the workload of the digital set-top box is reduced, and the working efficiency of the digital set-top box is improved.

Fig. 3 is a flowchart illustrating a third embodiment of a method for adjusting television volume according to an embodiment of the present invention. The embodiment relates to another specific process how the terminal determines the second sound intensity according to the first sound intensity and the preset sound intensity threshold range [ M, N ] when the digital television device is a digital set-top box or a television. As shown in fig. 3, based on the above embodiment, the step S102 specifically includes:

s301: the digital television equipment judges whether the first sound intensity is within the preset sound intensity threshold range [ M, N ]; if yes, go to step S302, otherwise go to step S303.

Specifically, the execution process of S301 may specifically refer to the description process of S201, which is not described herein again.

S302: and the digital television equipment determines that the sound intensity of all the audios and videos played by the television is the second sound intensity, and determines that the second sound intensity is equal to the first sound intensity.

Specifically, when the digital television device determines that the first sound intensity is within the preset sound intensity threshold range, the digital television device determines the sound intensity of all audio and video played by the current television as the second sound intensity, and determines that the second sound intensity is equal to the value of the first sound intensity, that is, the digital television device determines that the sound of the audio and video of the program played by the current television can meet the listening requirement of the user, optionally, the digital television device may fix the sound of all audio and video played by the television at the first sound intensity in a software or software and hardware combination manner.

S303: the digital television equipment judges the size relation between the first sound intensity and endpoint values M and N of the preset sound intensity threshold range; if the digital television equipment judges that the first sound intensity is smaller than M, the digital television equipment determines that the sound intensities of all audios and videos played by the television are the second sound intensity, and the second sound intensity is a value which is greater than or equal to M and smaller than or equal to N; if the digital television equipment judges that the first sound intensity is greater than the N, the digital television equipment determines that the sound intensities of all audios and videos played by the television are the second sound intensity, and the second sound intensity is a value which is greater than or equal to M and less than or equal to N.

Specifically, when the digital television device determines that the first sound intensity is not within the preset sound intensity threshold range, the digital television device determines that the sound of the audio/video of the current television playing program cannot meet the listening requirement of the user, and therefore, the digital television device further determines the size relationship between the first sound intensity and the endpoint values M and N of the preset sound intensity threshold range. When the digital television equipment judges that the first sound intensity is smaller than M, the digital television equipment determines that the sound of the audio and video of the program played by the current television is too small, the sound of the audio and video of the program played by the current television needs to be increased, namely the sound is increased from the first sound intensity to a second sound intensity, and the sound intensities of all the audio and video played by the current television are determined as the second sound intensity, wherein the second sound intensity is a value which is more than or equal to M and less than or equal to N; when the digital television equipment judges that the first sound intensity is larger than N, the digital television equipment determines that the sound of the audio and video of the program played by the current television is too large, the sound of the audio and video of the program played by the current television needs to be reduced, namely the sound is reduced from the first sound intensity to a second sound intensity, the sound intensities of all the audio and video played by the current television are determined to be the second sound intensity, and the second sound intensity is a value which is larger than or equal to M and smaller than or equal to N. The above adjustment can make the sound of the program played by the television meet the listening requirement of the user.

According to the method for adjusting the volume of the television, provided by the embodiment of the invention, the first sound intensity of the audio and video played by the television, which is detected by the receiving terminal of the digital television equipment, is judged, whether the first sound intensity is within the preset sound intensity threshold range [ M, N ] or not is judged, so that the second sound intensity is determined according to the judgment result, and the sound intensity of all the audio and video played by the television is adjusted to the second sound intensity, so that the sound requirement of a user on the audio and video played by the television is met, the listening experience of the user is improved, and the human-computer interaction intelligence among the digital television equipment, the terminal and the user is further improved; in addition, in this embodiment, when the digital television device is a digital set-top box, the method of this embodiment is adopted, and the digital set-top box is not required to process the private descriptor, so that the workload of the digital set-top box is reduced, and the working efficiency of the digital set-top box is improved.

Fig. 4 is a flowchart illustrating a fourth embodiment of a method for adjusting television volume according to the present invention. The embodiment relates to a specific process how a terminal adjusts the sound intensity of audio and video currently played by a television to the sound intensity meeting the listening requirement of a user according to a first sound intensity and a preset sound intensity threshold range [ M, N ] when the digital television equipment is a digital television front-end server. In this embodiment, the number of first sound intensities detected by the terminal, which are received by the digital television device (i.e., the digital television front-end server) within a preset time period, is L, that is, the number of first sound intensities fed back to the digital television front-end server by the terminal within the preset time period is L; and the L first sound intensities are obtained by detecting the sound intensities of the audios and videos played by the L televisions by the terminal in the preset time period. As shown in fig. 4, the method includes:

s401: and the digital television front-end server receives L first sound intensities corresponding to the L televisions detected by the terminal.

Specifically, the digital television front-end server receives a first sound intensity of an audio and video played by the television, which is fed back by the terminal, in a preset time period. Since the digital television front-end server can serve a plurality of digital television set-top boxes and a plurality of televisions (L is assumed, and L is an integer greater than 1) at the same time, the first sound intensity fed back to the digital television front-end server by the terminal is L within the preset time period.

S402: and the digital television front-end server determines the average value of the sound intensity according to the L first sound intensities.

Optionally, the average value of the sound intensities may be an arithmetic average value of the L first sound intensities, or may be a weighted average value of the L first sound intensities.

S403: the digital television front-end server determines the second sound intensity according to the sound intensity average value and the preset sound intensity threshold range, wherein both M and N are natural numbers larger than 0, and M is larger than N; the preset sound intensity threshold range is a sound intensity threshold range suitable for a user to listen.

Specifically, after determining a sound intensity average value according to the L first sound intensities fed back by the terminal, the digital television front-end server determines whether the sound intensity average value is within the preset sound intensity threshold range [ M, N ]. Optionally, the digital television front-end server determines whether the sound intensity average value is within a preset sound intensity threshold range by determining whether the sound intensity average value matches a certain sound intensity value within the preset sound intensity range; for example, if the average sound intensity value matches a value of a sound intensity within the preset sound intensity range, it indicates that the average sound intensity value is within the preset sound intensity threshold range (the "match" may be that the first sound intensity is equal to a value of a sound intensity within the preset sound intensity threshold range), and if the average sound intensity value does not match any value of a sound intensity within the preset sound intensity range, it indicates that the average sound intensity value is not within the preset sound intensity threshold range. Optionally, the digital television front-end server may further determine whether the sound intensity average value is within the preset sound intensity threshold range according to a determination result by determining the size of the sound intensity average value and an endpoint value of a preset sound intensity range. The embodiment of the present invention does not limit how the front-end server of the digital television determines whether the average value of the sound intensity is within the preset threshold range of the sound intensity.

When the digital television front-end server determines that the sound intensity average value is within the preset sound intensity threshold range, the digital television front-end server determines that the second sound intensity is equal to the sound intensity average value, namely the digital television front-end server determines that the average value of the sound of the audio and video of the current television playing program can meet the listening requirement of a user.

When the digital television front-end server determines that the sound intensity average value is not within the preset sound intensity threshold range, the digital television front-end server determines that the sound of the audio and video of the current television playing program cannot meet the listening requirement of a user, and therefore the digital television front-end server further judges the size relation between the sound intensity average value and the end point values M and N of the preset sound intensity threshold range. When the digital television front-end server judges that the average value of the sound intensity is smaller than M, the digital television front-end server determines that the average value of the sound of the audio and video of each currently played program is too small, and the sound of the audio and video of each currently played program needs to be adjusted, namely, the average value of the sound intensity is adjusted to a second sound intensity (namely, the second sound intensity is determined to be a value larger than the average value of the sound intensity, and the second sound intensity is larger than or equal to M and smaller than or equal to N); when the digital television front-end server judges that the average value of the sound intensity is larger than N, the digital television front-end server determines that the average value of the sound of the audio and video of the currently played programs of the televisions is too large, and the sound of the audio and video of the currently played programs of the televisions needs to be adjusted, namely, the average value of the sound intensity is reduced to a second sound intensity (namely, the second sound intensity is determined to be a value smaller than the average value of the sound intensity, and the second sound intensity is larger than or equal to M and smaller than or equal to N).

S404: and the digital television front-end server re-encodes the audio and video played by the L televisions according to the second sound intensity, and adjusts the sound of the audio and video played by the L televisions to the second sound intensity.

Specifically, after the digital television front-end server determines the second sound intensity, the audio and video played by each television is recoded according to the second sound intensity, namely, the intensity of the audio and video sound of the program of each television is adjusted, the adjusted audio and video is sent to each digital set-top box again and then sent to each television, and therefore the audio and video sound played by each television at present is adjusted to the second sound intensity.

According to the method for adjusting the volume of the television, provided by the embodiment of the invention, L first sound intensities fed back by a receiving terminal of the digital television device are used, the average value of the sound intensities is determined according to the L first sound intensities, whether the average value of the sound intensities is within the preset sound intensity threshold range [ M, N ] is judged, so that the second sound intensity is determined according to the judgment result, the played audio and video of the L televisions are recoded according to the second sound intensity, and the sound of the audio and video played by the L televisions is adjusted to the second sound intensity, so that the sound requirement of the audio and video played by the televisions by a user is met, the listening experience of the user is improved, and the man-machine interaction intelligence among the digital television device, the terminal and the user is further realized.

Fig. 5 is a schematic flowchart of a fifth embodiment of a method for adjusting television volume according to an embodiment of the present invention. The embodiment relates to a processing process of the digital television equipment when the digital television equipment is a digital set top box and a user continuously adjusts the sound of the audio and video played by the television with the current second sound intensity. In this embodiment, the digital set-top box presets a volume amplitude parameter, where the volume amplitude parameter is generally a maximum volume amplitude set when the digital set-top box leaves a factory (in a general case, a value of the volume amplitude parameter is not changed), and the digital set-top box inputs the volume amplitude parameter to the television, so that the television superimposes or otherwise processes the volume amplitude parameter and a volume amplitude of the television, and outputs a processed sound for a user to listen to. That is, the preset sound intensity threshold range is set under the volume amplitude parameter of the digital set top box. On the basis of the first embodiment, after the step S103, the method further includes:

s501: the digital set top box judges whether a third sound intensity sent by the terminal is received or not; the third sound intensity is the sound intensity detected by the terminal in a first time period after the sound intensity of the television is adjusted to the second sound intensity.

Specifically, after the digital set top box adjusts the sound intensity of the audio and video played by the television to the second sound intensity, the terminal is still in a monitoring state in the first time period, and when the terminal monitors that the sound of the audio and video played by the television continuously changes in the first time period, the terminal sends the detected third sound intensity to the digital set top box. At this time, the digital set top box is also in a state of judging whether the third sound intensity sent by the terminal is received in the first time period.

S502: if so, the digital set top box adjusts the volume amplitude parameter according to the third sound intensity, and outputs the adjusted volume amplitude parameter to the television.

Specifically, when the digital set top box receives the third sound intensity sent by the terminal within the first time period, it indicates that the user is still dissatisfied with the currently adjusted second sound intensity value. This case may be specifically: the preset sound intensity threshold range is a listening threshold range suitable for a normal user, but when an old user or a user at home has a rest, the second sound intensity adjusted according to the preset sound intensity threshold range is not suitable, according to the example given in the first embodiment, the preset sound intensity threshold range is 40dB to 70dB, it is assumed that the finally determined second sound intensity is 70dB, but for the old user, it still feels that 70dB cannot meet the listening requirement, the sound of the television is turned up manually (when the user adjusts the sound volume manually, the sound volume is also adjusted according to a certain step value, for example, from 70dB to 80dB, the sound volume is first turned up to 75dB, and then turned up to 80 dB). If the terminal detects that the sound of the television is no longer 70dB in the first time period, but is 75dB (third sound intensity), the terminal can quickly feed back the third sound intensity to the digital set-top box, and since the 70dB is the maximum value of the sound intensity threshold range which is set according to the maximum volume amplitude parameter on the digital set-top box and meets the listening requirement of the user, when the third sound intensity is greater than 70dB, it is indicated that the current volume amplitude parameter of the digital set-top box cannot be adjusted, the current volume amplitude parameter of the digital set-top box needs to be increased, and the increased volume amplitude parameter is output to the television, so that the television further increases the sound on the basis of the current 75dB, and the requirement of an old user can be met.

And when the third sound intensity detected by the terminal is smaller than the minimum value of the preset sound intensity threshold range in the scene of rest of the user at home, the volume amplitude parameter can be reduced according to the scene of the old user, and then the volume amplitude parameter is output to the television. The detailed process is not described herein.

In the method for adjusting the volume of the television provided by the embodiment of the invention, after the digital television device adjusts the sound of the audio and video played by the television to the second sound intensity, the digital television device judges whether a third sound intensity sent by the terminal is received, if so, the digital television device adjusts a preset volume amplitude parameter in the digital television device according to the third sound intensity, and outputs the adjusted volume amplitude parameter to the television. The method of the embodiment of the invention further improves the listening experience of the user and improves the human-computer interaction intelligence among the digital television equipment, the terminal and the user.

The following embodiment is a recommendation process for adjusting the sound intensity of the currently played audio and video by the digital television device according to the sound test instruction of the user. In the following embodiments, the digital television device may be a voice-controlled television or a digital set-top box.

Fig. 6 is a flowchart illustrating a sixth embodiment of a method for adjusting television volume according to an embodiment of the present invention. The digital television device related to this embodiment adjusts the specific process of the sound intensity of the audio and video currently played by the television according to the sound test instruction input by the user. As shown in fig. 6, the method includes:

s601: the digital television equipment acquires a test instruction with the sound intensity as the first sound intensity.

Specifically, in this embodiment, the digital television device may be a voice-controlled television or a digital set-top box. The digital television equipment acquires a test instruction with the first sound intensity, and when the digital television equipment is a voice-controlled television, the test instruction with the first sound intensity, which is input by a user, can be directly acquired; when the digital television equipment is a digital set-top box, the digital set-top box can transmit a test instruction which is input by a user and has the first sound intensity to the digital set-top box after receiving the test instruction. For example, when the digital television device is a television, a user turns on the television (the television does not play a program at this time), the user pops up a character or letter for the user to read, the user reads the character or letter with the first sound intensity, and for the television, the character or letter read out with the first sound intensity is a test instruction, and the television can acquire the first sound intensity. It should be noted that, when the digital television device is a television, software or hardware for identifying the first sound intensity may be integrated on the digital television device; when the digital television equipment is a digital set-top box, software or hardware for identifying or analyzing the first sound intensity is not integrated on the television, the identification or analysis of the first sound intensity can be completed by the digital set-top box, and the television only plays a role in forwarding a test instruction with the sound intensity being the first sound intensity.

S602: and the digital television equipment plays the test instruction with a second sound intensity according to the first sound intensity.

Specifically, after the digital television device obtains the test instruction with the first sound intensity, the digital television device itself should play the test instruction with the same sound intensity for the user to determine whether the volume is appropriate, but due to the influence of hardware or software, the digital television device plays the test instruction with the second sound intensity. The second sound intensity may be the same as or different from the first sound intensity.

S603: the digital television equipment executes judgment operation; wherein the judging operation comprises: the digital television equipment judges whether an adjusting instruction input by a user is received within a preset time period; and if so, the digital television equipment adjusts the second sound intensity according to the adjusting instruction, plays the test instruction according to the adjusted second sound intensity, and continues to execute the judging and adjusting operation until the adjusting instruction of the user is not received within the preset time period.

Specifically, after the digital television device plays the test command with the second sound intensity, the user can determine whether the second sound intensity meets the listening requirement of the user. If the adjustment instruction is not satisfied, the user inputs an adjustment instruction to the digital television equipment, and meanwhile, the digital television equipment also executes the judgment operation, namely, whether the adjustment instruction input by the user is received within a preset time period is judged. If the digital television equipment judges that the adjusting instruction is received, the second sound intensity is adjusted according to the adjusting instruction, the test instruction is played again according to the adjusted second sound intensity, and the user is continuously provided to judge whether the listening requirement of the user is met, so that the user determines whether to input the adjusting instruction again to the digital television equipment, namely, the digital television equipment continuously executes the judging operation until the adjusting instruction of the user is not received in the preset time period, namely, until the adjusted second sound intensity meets the listening requirement of the user.

S604: and the digital television equipment stores the adjusted second sound intensity.

Specifically, the digital television device stores the adjusted second sound intensity, and plays the audio and video with the adjusted second sound intensity.

According to the method for adjusting the television volume, provided by the embodiment of the invention, a test instruction with the sound intensity being the first sound intensity is obtained through the digital television equipment, the test instruction is played with the second sound intensity according to the first sound intensity, and the judgment operation is further executed, namely whether an adjusting instruction input by a user is received within a preset time period is judged; if receiving an adjusting instruction input by a user within a preset time period, the digital television equipment adjusts the second sound intensity according to the adjusting instruction, and plays the test instruction with the adjusted second sound intensity, so as to continue to execute the judging operation until the adjusting instruction of the user is not received within the preset time period, and then stores the adjusted second sound intensity. According to the method provided by the embodiment of the invention, the listening experience of the user is improved through the instruction interaction between the digital television equipment and the user, and the man-machine interaction intelligence between the digital television equipment and the user is realized.

Fig. 7 is a flowchart illustrating a seventh embodiment of a method for adjusting television volume according to an embodiment of the present invention. The embodiment relates to a specific process that when the digital television equipment is a digital set top box, the digital television equipment adjusts the sound intensity of the audio and video played by the television to meet the listening requirement of the user according to the test instruction and the adjusting instruction of the user. On the basis of the above embodiment, as shown in fig. 7, the method includes:

s701: the digital set top box acquires a first test instruction with the sound intensity as the first sound intensity through the television.

Specifically, in this embodiment, software or hardware for identifying or analyzing the first sound intensity is not integrated on the television, the identification or analysis of the first sound intensity may be completed by the digital set top box, and the television only plays a role of forwarding a test instruction with the sound intensity being the first sound intensity. That is, the first test command, whose sound intensity is the first sound intensity, is not recognizable to the television.

S702: and the digital set top box analyzes the first sound intensity to obtain a second test instruction of a second sound intensity recognizable by the television, and the second test instruction is played by the television at the second sound intensity.

Specifically, after receiving a first test instruction with a first sound intensity forwarded by the television, the digital set top box analyzes the first test instruction into a second test instruction with a second sound intensity recognizable by the television, and then broadcasts the second test instruction with the second sound intensity through the television, so that a user can judge whether the listening requirement of the user is met.

S703: the digital set top box executes judgment operation; wherein the judging operation comprises: the digital set top box judges whether an adjusting instruction input by a user through the television is received within the preset time period; if yes, the digital set top box adjusts the second sound intensity according to the adjusting instruction, plays the test instruction according to the adjusted second sound intensity, and continues to execute the judging operation until the adjusting instruction of the user is not received in the preset time period.

Specifically, after the television plays the second test command with the second sound intensity, the user can determine whether the second sound intensity meets the listening requirement of the user. If the adjustment instruction is not satisfied, the user inputs an adjustment instruction to the digital television device (for example, the user inputs an adjustment instruction of "turn the sound up by 5 dB" or "turn the sound down by 5 dB") by voice, then the television inputs the adjustment instruction to the digital set-top box, and correspondingly, the digital set-top box also performs the above-mentioned judgment operation, that is, whether the adjustment instruction input by the user through the television is received within the preset time period is judged. If the digital set top box judges that the adjusting instruction is received, the second sound intensity is adjusted according to the adjusting instruction, the second test instruction is played again through the television according to the adjusted second sound intensity, and the user is continuously provided with a judgment result whether the second test instruction meets the listening requirement of the user, so that the user determines whether the adjusting instruction is input again to the digital set top box through the television, namely, the digital set top box continuously executes the judgment operation until the adjusting instruction input by the user through the television is not received in the preset time period, namely, the adjusted second sound intensity meets the listening requirement of the user.

S704: and the digital set top box stores the adjusted second sound intensity.

Those of ordinary skill in the art will understand that: all or part of the steps for implementing the method embodiments may be implemented by hardware related to program instructions, and the program may be stored in a computer readable storage medium, and when executed, the program performs the steps including the method embodiments; and the aforementioned storage medium includes: various media that can store program codes, such as ROM, RAM, magnetic or optical disks.
