As one of ordinary skill in the art can know, with the evolution of audio playing and the appearance of new service scenes, the technical scheme provided by the application is also applicable to similar technical problems.

The following describes the above-described embodiments in detail.

Embodiments of the present application will be described in terms of an audio playback apparatus that may be integrated into a computer device. The computer device may be a terminal or a server, and the terminal may be a device such as a mobile phone, a tablet computer, a notebook computer, an intelligent television, a wearable intelligent device, a personal computer (PC, personal Computer), and the like. As shown in fig. 2, a flow chart of an audio playing method provided by the present application is shown, and the method includes:

step 101, playing audio data by adopting an enhanced audio return channel based on a built-in audio player in the terminal.

The audio feedback channels (Audio Return Channel, ARC) enable the television to transmit audio to the external power amplifier such as the sound bar through a single HDMI cable, so that the settings of the television and the home theater are greatly simplified. Like ARC, eARC also allows televisions to use a single HDMI cable to send audio generated by built-in streaming applications, cables, satellites, and other source devices to a speaker-strip and other external power amplifier, and eARC supports much greater bandwidth and speed than ARC, thus allowing the transmission of high quality, uncompressed audio.

Typically, home televisions are essentially binaural and have built-in audio, i.e., no eARC is used. However, along with the continuous promotion of people's image quality and audio experience requirement to audio and video, people can no longer satisfy the audio that is provided with stereo set that the television was taken, alright external power amplifier improves audio playback's audio at this moment to can promote and watch experience. When we need external power amplifier, we need eARC to transmit audio data, and if we need TV stereo to make multi-channel output, we can also use eARC protocol to transmit data. However, only one path of channel exists in the television core at present, and when the built-in audio of the television uses the eARC to perform data transmission, the eARC device cannot be externally connected to perform data transmission. In this regard, the present application provides an audio playing method to solve the problem, and the method provided by the present application is described in detail below.

In the embodiment of the present application, the terminal may be any device such as a television, a personal computer, etc., and here, a television will be taken as an example for explanation. An embedded audio player based on eARC transmission can be used in the television for audio playing, wherein the embedded audio player can be a multi-channel sound (or loudspeaker). The built-in audio player based on eARC transmission is adopted for audio playing, so that better sound effect experience can be obtained.

In some embodiments, the audio data is played by an enhanced audio backhaul channel based on a built-in audio player in the terminal, including:

1. the method comprises the steps that pins of an audio player built in a control terminal are subjected to enhanced audio return channel handshake;

2. and playing the audio data based on the built-in audio player after the handshake is successful.

In the embodiment of the application, the audio data playing is performed based on the built-in audio player of the terminal, which may be that the eARC handshake is performed on the built-in audio player first, and then the audio data playing is performed after the handshake is successful. Specifically, the pin of the built-in audio player in the terminal may be controlled to perform the eerc handshake, where the pin of the built-in audio player may specifically be an HDP pin.

Step 102, when detecting that the terminal accesses the external device, detecting the device type of the external device.

When the television adopts the built-in audio player based on eARC transmission to play audio, the external equipment accessed to the television can be detected in real time. If no external device is connected, the television continues to adopt the built-in audio player based on eARC transmission to play the audio. If the external equipment is detected to be connected to the television, the equipment type of the equipment can be further detected. Among the types of devices that access television include, but are not limited to: audio devices (e.g., external speakers), storage devices (e.g., flash disk), and other devices.

Step 103, when the device type of the external device is audio device, switching to use the external device to play the audio data by adopting the enhanced audio return channel.

When the device type of the external device connected to the television is detected to be the audio device, one path of eARC channel in the television core can be switched from the built-in audio player to the external device for playing. It is understood that the external device is an external device supporting the eARC transmission. Therefore, the audio playing method provided by the application solves the problem that only one path of eARC channel exists in the television core to cause that only one player can adopt eARC transmission to play audio by managing eARC transmission resources.

According to the above description, according to the audio playing method provided by the embodiment of the application, the audio data is played by adopting the enhanced audio return channel based on the built-in audio player in the terminal; when the terminal is detected to be connected with the external equipment, detecting the equipment type of the external equipment; when the equipment type of the external equipment is audio equipment, the external equipment is switched to play the audio data by adopting the enhanced audio return channel. Therefore, the audio playing method provided by the application can manage the enhanced audio return channel resources, can detect whether the terminal is connected with the external audio equipment in real time when the audio player arranged in the terminal is adopted for playing the enhanced audio return channel, can be connected with the external audio equipment and can be switched to the external equipment for playing the enhanced audio return channel when the terminal is detected to be connected with the external audio equipment, thereby enriching the use scene of the enhanced audio return channel and improving the user experience.

Accordingly, the embodiment of the application further describes the audio playing method provided by the application in detail. As shown in fig. 3, another flow chart of the audio playing method provided by the present application includes:

step 201, when receiving an audio playing instruction, the television detects whether an external power amplifier is connected.

Wherein, before receiving the audio playing instruction, the user can set the audio playing mode to the automatic mode. The automatic mode is that when receiving an audio playing instruction, if no external power amplifier is connected, the built-in audio player is preferred to play audio, however, when detecting that the external power amplifier is connected, the external power amplifier is preferred to play audio.

The process of setting the audio playing mode in the television may include:

1. displaying an audio output mode selection interface on a display interface of the terminal;

2. when receiving a selection operation aiming at a preset audio output mode, triggering a built-in audio playing channel of the terminal to carry out enhanced audio return channel handshake;

3. when receiving an audio playing task, the built-in audio player in the terminal plays the audio data in the audio playing task by adopting the enhanced audio feedback channel.

In the embodiment of the application, the mode setting interface of the audio output mode can be displayed on the display interface of the television, and particularly, the interface can be selected due to the fact that the audio output mode is displayed. The interface may include a default mode, a built-in player priority mode, and the like, where the default mode may be to preferentially play audio from the external power amplifier when detecting that the television is connected to the external power amplifier, or to play audio from the built-in audio player. Because the connection of the eerc needs to go through a special handshake protocol, and it needs to be ensured that no disconnection occurs during the use, otherwise, sound interruption is caused. Thus, after determining the audio output mode, for example, selecting the built-in player priority mode, the built-in audio player of the television is triggered to perform the eARC handshake, specifically, the eARC handshake may be performed for the HDP pin triggering the built-in channel. After the handshake is successful, the built-in eARC channel can be used, that is, the built-in audio player is adopted to play audio data based on eARC.

In the automatic mode, when the television terminal receives an audio playing instruction, the television terminal can detect whether the television is connected to the external power amplifier or not at present.

The method for detecting whether the television is connected with the external power amplifier or not at present comprises the following steps:

A. when the terminal is detected to be connected with the external equipment, a consumer electronic control command is sent to the external equipment;

B. and determining the equipment type of the external equipment according to the response condition of the external equipment to the electronic control command.

In the embodiment of the application, whether the television is connected with the external equipment or not can be detected first, and when the television is not connected with the external equipment, the television normally works in the built-in eARC channel to play audio data by adopting the built-in audio player. When the television is detected to be connected to the external device, whether the external device is an audio device or not needs to be further verified. If the external device is not the audio device, the external device normally works in the built-in eARC channel and plays audio data by adopting a built-in audio player; when the external device is an audio device, switching to the external eARC channel adopts the external device to play audio data based on the eARC channel.

In the embodiment of the present application, whether the external device is an audio device is detected, specifically, whether the device supports a consumer electronics control command (Consumer Electronic Control, CEC) may be detected first, when the external device supports CEC, whether the device is an audio device may be determined through a CEC command, and if the device does not support CEC, whether the device is an audio device may be determined directly through an eARC handshake.

Step 202, when the external power amplifier is not detected to be connected, the television adopts the built-in audio player to play the audio data based on the eARC channel.

Wherein, at this time, the television normally works in the built-in eARC channel, and the built-in audio player is adopted to play audio data based on the eARC channel, and the detection of the television access equipment is kept in real time. If the television is not detected to be connected with the external power amplifier, the television is kept to adopt the built-in audio player to play the audio data based on the eARC channel.

And 203, triggering the television and the external power amplifier to carry out eARC handshake when the access to the external power amplifier is detected.

When the television is detected to be connected with the external power amplifier in real-time detection, the eARC channel is switched to the external channel, and an HDP pin of the external channel is triggered to perform eARC handshake. It is understood that the external power amplifier is an external power amplifier supporting the eerc.

In step 204, when the eARC handshake is successful, the television switches to play the audio data based on the eARC channel using the external power amplifier.

When performing the eARC handshake, there may be a handshake failure, if the eARC handshake is successfully implemented, the television will work to further external eARC channels, and an external device is used to play audio data based on the eARC channels.

In step 205, when the eARC handshake fails, the television initializes the ARC channel.

When the eARC handshake fails, the television may then further perform ARC channel initialization processing.

In step 206, when the ARC channel is initialized successfully, the television uses the external power amplifier to play the audio data based on the eARC channel.

When the ARC channel is successfully initialized, the television performs eARC handshake again, and when the handshake is successful, the television works on the external eARC channel, and external equipment is adopted to play audio data based on the eARC channel. If the ARC channel initialization is not successful, the built-in eARC channel still works, and the built-in audio player is adopted to play the audio based on the eARC channel.

By the audio playing method provided by the application, a plurality of audio devices can transmit audio data through eARC, the problem of eARC resources in a television can be solved, and the eARC function of an external power amplifier is compatible. In addition, in the application, the television can adopt the multi-channel loudspeaker transmitted by eARC, thereby greatly improving the hearing effect experience of the user.

In order to better implement the above method, the embodiment of the present application further provides an audio playing device, which may be integrated in a terminal or a server.
