Technical Field
The invention relates to the technical field of video and audio playing, in particular to a method for selectively listening to a television program with multilingual sound by using a phase inverter.
Background
In recent years, video programs such as television programs having various languages and sounds have appeared on the market, and along with this, playback apparatuses such as televisions capable of switching languages and sounds have appeared; for example, when the tv program contains multiple language sounds such as english, german and chinese, the user can select one of the language sounds on the UI menu for playing through the tv remote controller, and even can select to play multiple language sounds simultaneously (i.e., play a mixed sound formed by mixing multiple language sounds).
In the prior art, the content of a television signal often includes more than two audio track sounds, a user can only listen to the same language sound at the same time usually, but each person is different for the language sound he wants to listen to, when a plurality of users watch the same television program in the same environment and the television program supports the language sounds of more than two language systems (i.e., multiple language sounds), the television can simultaneously dial more than two language sounds, the plurality of users wear earphones capable of selecting the language systems respectively, and receive the desired language sound through the earphones respectively, so as to achieve the purpose of enabling the plurality of users to listen to the respective desired language sound at the same time, and the method can be realized by consuming very high earphone cost besides discomfort caused by wearing the earphones.
Disclosure of Invention
The invention aims to provide a method for selectively listening to a multilingual sound television program by using an inverter, which has the advantages of reasonable design and low cost, and can allow a plurality of users to listen to the language sound which is pre-listened to by each user without wearing earphones.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for selectively listening to a multilingual sound television program using an inverter, comprising the steps of:
1) after the television is started, judging whether the currently played television program has multiple language sounds, if so, executing the step 2), and if not, playing the language sounds according to a normal playing mode;
2) the user confirms whether the television starts a multi-language sound playing mode for simultaneously playing multi-language sounds, if so, the step 3) is executed, and if not, the language sounds are played according to a normal playing mode;
3) the television simultaneously plays the multi-language sounds of the television program according to the multi-language sound playing mode;
4) installing an inverter for selectively inverting the language sound at the periphery of each user, and configuring different IDs in a television remote controller, wherein the different IDs are responsible for setting a set value of the selected language sound for controlling each inverter by the television;
5) each user selects a selected language sound set value of a television for controlling a corresponding inverter through a television remote controller;
6) after selection, the television synchronously transmits signals containing the voice setting values of the selected language and the voice of the non-selected language to an inverter at the periphery of the corresponding user, and the inverter emits an inverted sound wave with the same amplitude as the voice signal of the non-selected language for counteracting the voice signal of the non-selected language, so that each user can hear the voice of the selected language selected by each user.
Preferably, the normal play modes in step 1) and step 2) are: the motor only plays one language sound in the television program so that all users hear the same language sound.
Preferably, the inverter in step 4) is installed at a seat of each user.
Preferably, the inverter in step 5) further judges whether the non-selected language sound is effectively eliminated after the peripheral sound is collected by the microphone, and adaptively adjusts the amplitude or phase of the inverted sound wave according to the judgment result.
Preferably, the inverter in the step 5) is provided with a microphone module for collecting peripheral sound, a comparison module for judging whether non-selected language sound is effectively eliminated or not and an adjusting module for adaptively adjusting amplitude or phase of the inverted sound wave. The design can judge whether the non-selected language sound is effectively eliminated or not through the comparative analysis of the comparison module according to the peripheral sound collected by the microphone module, and then the adjustment module adaptively adjusts the amplitude or the phase of the antiphase sound wave according to the judgment result, so that other language sounds which a user on a seat does not want to receive are largely eliminated, and the function that the user only hears the selected language sound is achieved.
By adopting the technical scheme, when more than two users watch the same television program in the same environment and the television program supports more than two language sounds (namely, the television program has multiple language sounds), all the users can select the voice sound of the television through the television remote controllers with different IDs without wearing earphones, and utilize the inverters arranged at the periphery of each user to transmit the opposite-phase sound waves with the same amplitude, so that the unselected language sounds are cancelled when encountering the opposite-phase sound waves with the same amplitude, the language sounds which the users do not want to receive at the periphery of the seat can be greatly eliminated, and the aim that each user only listens to the selected language sounds is fulfilled.
