Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments can be mutually combined and referred to without contradiction.

An embodiment of the present application relates to an audio signal transmission method, which may be applied to a control unit, which may be an Application Specific Integrated Circuit (ASIC). In this embodiment, an audio signal is obtained and converted into an ARC/eARC signal; the ARC/eARC signal is wirelessly transmitted to an output terminal device through WIFI; the output terminal equipment is controlled to output the received ARC/eARC signal to the audio playing equipment, and the received ARC/eARC signal is wirelessly transmitted to the output terminal equipment through WIFI by acquiring the audio signal and converting the audio signal into the ARC/eARC signal to obtain the audio playing quality with high sound channel number, so that the equipment can be flexibly arranged in one space without being influenced by wiring; and controlling the output terminal equipment to output the received ARC/eARC signal to audio playing equipment. By the method, the user can save the expense of purchasing the ARC/eARC television, and the project maintenance cost and difficulty are reduced. The implementation details of the audio signal transmission method of the present embodiment are specifically described below, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment.

As shown in fig. 1, in step 101, an Application Specific Integrated Circuit (ASIC) as a control unit acquires an initial signal from an initial signal source, and processes the initial signal into an audio signal.

The current ARC/eARC is mainly to enable a television to transmit audio to a sound bar or AVR through a single HDMI cable, thereby greatly simplifying the setup of televisions and home theatres. Previously, decoding high bit rate audio such as Dolby Atmos was not able to be output as original sound, since most televisions were limited to outputting surround sound and even stereo audio. While using eARC now, HDMI devices can be plugged directly into the television, which will then send high quality audio directly to the speakers through the eARC port.

The application needs to save the television which is necessary in the prior proposal, but only the initial signal is provided by the signal source, but the audio playing equipment can only support the playing of the audio signal, and the conversion of the initial signal can not be realized on the premise of no television, so in the step, after the initial signal is obtained, the initial signal needs to be processed into the audio signal, and the conversion resource is saved as much as possible, thereby replacing the function of the television to realize the conversion of the initial signal.

In one example, an initial signal is obtained, such as: HDMI signals, S/PDIF signals, and L/R signals.

Wherein L/R belongs to analog audio signals, and S/PDIF and HDMI belong to digital signals.

The present application obtains audio and video from a variety of different types of mainstream data interfaces including, but not limited to, HDMI interface, S/PDIF interface, etc., and then strips audio from the different signals obtained from the various interfaces, e.g., strips audio from HDMI, S/PDIF and L/R to ARC/eARC wireless scheme.

In one example, if the acquired initial signal is the L/R signal, converting the L/R signal into an audio signal through an analog-to-digital converter (ADC); if the acquired initial signal is the S/PDIF signal, converting the S/PDIF signal into an audio signal through an AND gate chip; if the acquired initial signal is an HDMI signal, the HDMI signal is converted into an audio signal by a Transition Minimized Differential Signaling (TMDS) technique.

The L/R is converted into an I2S format digital audio input ASIC through a DAC; S/PDIF is converted into single-ended audio signal to ASIC through NOT IC (AND gate chip); the HDMI is directly input to an ASIC dedicated HDMI interface, and the ASIC has a dedicated module (module) to output the I2S or S/PDIF audio embedded from the outside or the audio signal of the TMDS stripping process from the HDMI interface.

In step 102, an Application Specific Integrated Circuit (ASIC) as a control unit converts the audio signal into an ARC/eARC signal;

eARC (full Enhanced Audio Return Channel) is an upgraded version of ARC (full Audio Return Channel) with eARC built on top of ARC. ARC enables the television to send audio to a sound bar or AVR over a single HDMI cable, greatly simplifying the setup of televisions and home theatres. In the original HDMI standard, a television can only receive audio and video through HDMI, and cannot transmit audio back. To transmit audio, a TOSLink or coaxial cable is required. Like ARC, eARC also allows televisions to use a single HDMI cable to send audio generated by built-in streaming applications, cable, satellite, and other source devices (e.g., a gaming machine or a blue-ray player) to your soundbar or AVR, however, eARC supports much greater bandwidth and speed than ARC and thus can transmit high quality, uncompressed audio, which ARC cannot achieve.

In addition, the eARC includes its own data channels for allowing the television to discover compatible eARC audio playback devices. The audio playback apparatus also uses it to transmit the supported audio format and the television transmits the mouth-sync correction data to the audio playback apparatus, which will be under the control of the control unit since the present application does not require the use of a television.

In addition, the eerc/ARC supports CEC (Consumer Electronics Control, consumer electronic control) functions, and can control on/off of an audio device, and increase/decrease/mute functions of volume using a television remote controller.

After the initial signal is stripped out of the audio, the audio is then converted into an ARC/eARC signal, in a specific example, the ASIC may stack the audio input in three formats, where ARC is a single-ended signal, eARC is a differential signal, but eARC is a compatible ARC signal, and a dedicated chip is used to transmit the stacked audio to the WIFI wireless receiving module through the op-amp and gate chip, where the op-amp and gate chip play a role of being compatible with various receiving devices.

In step 103, an Application Specific Integrated Circuit (ASIC) as a control unit wirelessly transmits the ARC/eARC signal to an output device through WIFI;

in the related art, if audio/video playback is required, in addition to the equipment compatible with eerc, a high-speed HDMI cable or ultra-high-speed HDMI cable with ethernet is required to connect the signal source and the equipment to use the audio/video playback function. However, if other HDMI 2.1 functions are intended to be used on the same HDMI cable, a more complex line connection scheme will be used and the quality requirements of the cable will be increased. And the ARC/eARC signal is wirelessly transmitted to the output end equipment through WIFI, so that a data line or HDMI cable can be saved, the signal is prolonged, and the application range is improved.

In one example, the sending the ARC/eARC signal to the output device wirelessly through WIFI includes: and respectively sending the ARC/eARC signals to a plurality of different corresponding output terminal devices through a plurality of channels of the WIFI.

Specifically, in this embodiment, as shown in fig. 2, an audio signal acquired from a signal source 201 is wirelessly connected by an input (TX) device 202 of the present application and an output (RX) device 203 of the present application through n channels of WIFI, so that the present application can implement that one audio signal can be received by a plurality of RX devices 203, and n RX devices 203 are connected to n audio output devices (audio playing devices) 204, so that one audio signal can be played by a plurality of audio playing devices 204 in real time.

In step 104, an Application Specific Integrated Circuit (ASIC) as a control unit controls the output terminal device to output the received ARC/eARC signal to an audio playing device.

In one example, the audio playing device includes: ARC/eerc input device, fiber optic audio device, headphones connected with 3.5mm headphone jack, and horn.

The application is also compatible with various output audio interfaces, and has better compatibility of converting audio into ARC/eARC signals, and even if different types of interfaces are installed on various output audio playing devices, the interfaces are the interfaces for correspondingly acquiring HDMI signals, S/PDIF signals and L/R signals, and the output end device of the application can convert and output the ARC/eARC signals to the audio playing device to realize audio playing.

The audio playing device can also be a sound device, a power amplifier device, and the sound device is a short name of a sound system, and refers to a whole set of device capable of playing back audio signals. And the power amplifier is one of the basic devices in the sound system.

The overall working principle of the present application is shown in fig. 3, in which the input (TX) device is controlled by the control unit #4, and the output (RX) device is controlled by the control unit #8, and it should be noted that although the control unit #4 and the control unit #8 are separated in this example, the cooperative control can be implemented through a wireless connection, which is not limited herein.

In an input Terminal (TX) device, a control unit #4 is in communication with a signal source #1, a video/audio processing module #2, and a WIFI module TX #3, where under the control of the control unit #4, the video/audio processing module #2 obtains an initial signal from the signal source #1, processes the initial signal into the audio signal, obtains an audio signal, and converts the audio signal into an ARC/eerc signal. And the ARC/eARC signal is wirelessly transmitted to an output end (RX) device in the form of WIFI through a WIFI module TX#3, the output end (RX) device receives the ARC/eARC signal through a WIFI module RX#5 under the control action of a control unit#8, and the ARC/eARC signal is subjected to further audio processing through an audio processing module#6, and the processed audio is transmitted to an ARC/eARC input device, a power amplifier and a loudspeaker#7 so as to realize audio playing of the device.

In this embodiment, by acquiring an audio signal and converting the audio signal into an ARC/eacrc signal to obtain audio playing quality with a high channel number, and wirelessly transmitting the ARC/eacrc signal to an output device through WIFI, the device can be flexibly arranged in a space, and is not affected by wiring; and controlling the output terminal equipment to output the received ARC/eARC signal to audio playing equipment. By the method, the user can save the expense of purchasing the ARC/eARC television, and the project maintenance cost and difficulty are reduced.
