Background
As shown in fig. 1, in order to use power amplifiers in most of Audio playing devices in the market to encode and output Audio to be output, and particularly to use power amplifiers with an Audio Return Channel (ARC) function to perform ARC encoded output on the Audio to be output, a user is generally required to select an Audio encoded output mode on a multimedia resource acquisition device so that the power amplifiers can perform ARC decoding output on the Audio to be output. The multimedia resource acquiring device can be a TV, and the audio coding output modes which can be selected by a user comprise the following categories: RAW, Pulse Code Modulation (PCM), Dolby Digital (Dolby Digital), and Dolby Digital Plus (Dolby Digital Plus).

For example, the audio coding output mode selected by the user is RAW, the multimedia resource acquisition device does not perform any processing on the audio to be output, and the audio is directly transmitted to a power amplifier in the audio playing device connected with the multimedia resource acquisition device, and the power amplifier may not decode the audio to be output, so that the audio playing device cannot play the audio; when the audio coding output mode selected by the user is PCM, the multimedia resource acquisition equipment forcibly codes the audio to be output into PCM audio and sends the PCM audio to the power amplifier, because the power amplifier is possibly provided with a forced decoding mode which is not PCM, if the PCM audio is forcibly decoded, the quality of the audio played by the audio playing equipment is reduced, and even the audio cannot be played; when the audio coding output mode selected by the user is Dolby Digital or Dolby Digital Plus, the multimedia resource obtaining device codes the audio to be output into the audio corresponding to Dolby Digital or Dolby Digital Plus in a forced mode, and sends the audio corresponding to Dolby Digital or Dolby Digital Plus to the power amplifier.

Detailed Description
The present invention will be described in further detail with reference to the attached drawings, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Example 1:
fig. 2 is a flowchart of a method for outputting audio according to an embodiment of the present invention, where the method includes:
s201: the multimedia resource obtaining equipment obtains first attribute information of a first audio to be output, wherein the first attribute information comprises a first audio format and a first channel number of the first audio.
The audio output method provided by the embodiment of the invention is applied to multimedia resource acquisition equipment, and the multimedia acquisition equipment can be a TV.
In order to accurately determine a processing method of a first audio to be output, after receiving the first audio to be output, a multimedia resource obtaining device obtains first attribute information of the first audio, where the first attribute information includes a first audio format and a first channel number.
S202: and acquiring second attribute information of a power amplifier in the audio playing equipment connected with the multimedia resource acquiring equipment, wherein the second attribute information comprises each second audio format capable of performing audio decoding by the power amplifier and a second channel number corresponding to each second audio format.
In order to seek a better hearing experience, most users often connect an audio playing device to the Multimedia resource acquiring device, and in general, the audio playing device is connected to the Multimedia resource acquiring device through a High Definition Multimedia Interface (HDMI) line. For example, besides PCM, one mainstream power amplifier can perform audio decoding in an audio format, which includes one or two other audio formats, such as Dolby Digital, Dolby Digital Plus, Digital cinema System (DTS), and the number of channels corresponding to these audio formats is also different, and the number of channels corresponding to most audio formats is 6 channels or 8 channels.
Therefore, in order to determine the processing method of the first audio to be output more accurately, the multimedia resource obtaining device further needs to obtain the second attribute information of the power amplifier in the audio playing device, and specifically, after the multimedia resource obtaining device detects that the audio playing device is connected to itself, the multimedia resource obtaining device sends a request for obtaining the second attribute information of the power amplifier to the audio playing device, so that the audio playing device sends the corresponding second attribute information of the power amplifier to the multimedia resource obtaining device.
The second attribute information of the power amplifier may include each second audio format in which the power amplifier can perform audio decoding and the number of channels corresponding to each second audio format, where the number of the second audio formats in which different power amplifiers can perform audio decoding is different, and generally, a plurality of audio formats, for example, 3, in which mainstream power amplifiers can perform audio decoding are provided.
S203: and determining a processing method of the first audio according to the first attribute information and the second attribute information, and sending the first audio processed by the corresponding processing method to the audio playing device.
In order to avoid the situation that the audio playing device cannot play audio and improve the quality of the audio played by the audio playing device, the multimedia resource acquiring device needs to determine a processing method of a first audio to be output, specifically, the processing method of the first audio may be determined according to the first attribute information and the second attribute information, specifically, the levels of audio formats in the first attribute information and the second attribute information may be compared, and a processing mode of the first audio is determined according to an audio format with the lowest level, so that the audio playing device plays the audio. For example, the multimedia resource obtaining device performs corresponding encoding and decoding processing on the first audio according to the encoding and decoding mode corresponding to the audio format with the lowest level, and sends the first audio after encoding and decoding processing to the audio playing device.
According to the embodiment of the invention, the multimedia resource acquisition device determines the processing method of the first audio according to the acquired first attribute information of the first audio to be output and the acquired second attribute information of the power amplifier in the audio playing device connected with the multimedia resource acquisition device, and sends the first audio processed by the corresponding processing method to the audio playing device, so that the situation that the audio playing device cannot play the audio is avoided, and the quality of the audio played by the audio playing device is improved.
Example 2:
in order to more accurately obtain the second attribute information of the power amplifier, on the basis of the above embodiment, if the power amplifier has an ARC function, the obtaining of the second attribute information of the power amplifier in the audio playing device connected to the multimedia resource obtaining device includes:
sending an ARC connection available setting signal to the audio playing equipment, and receiving an ARC function connection available feedback signal sent by the audio playing equipment;
sending an ARC enabling request to the audio playing equipment, and receiving an enabling signal sent by the audio playing equipment;
and sending an audio description request to the audio playing device, and receiving feedback information which is sent by the audio playing device and comprises the second attribute information.
In the embodiment of the present invention, the power amplifier in the audio playing device connected to the multimedia resource acquiring device may be a power amplifier with an ARC function, and if the power amplifier in the audio playing device is a power amplifier with an ARC function, the second attribute information of the power amplifier may be acquired.
Fig. 3 is a schematic diagram of a process of acquiring second attribute information of a power amplifier according to an embodiment of the present invention, where a multimedia resource acquiring device, such as a TV, may continuously send a power amplifier power-on detection signal after being powered on until receiving a power-on signal sent by the power amplifier according to the power amplifier power-on detection signal, where the power amplifier power-on detection signal may be, for example, 0x8 f.
In order to determine whether the ARC function of the power amplifier is available, the multimedia resource acquiring device needs to send an ARC connection available setting signal to the power amplifier, where the ARC connection available setting signal may be, for example, 0x 70.
If the ARC function of the power amplifier is available, the power amplifier sends a feedback signal carrying a message that the ARC function is available for connection to the multimedia resource acquisition device, where the feedback signal is 0x72, specifically, according to a determination result of whether the ARC function of the power amplifier is available for connection, the feedback signal may carry messages with different contents in 0x72, and at this time, the message content carried by the feedback signal indicates that the ARC function is available for connection.
According to the received feedback signal, if the multimedia resource acquiring device determines that the ARC function connection of the power amplifier is available, ARC enable (ARC enable) operation is performed on the power amplifier, specifically, the multimedia resource acquiring device sends a power amplifier initialization request to the power amplifier, even if the power amplifier initialization request is 0xc 3; and after receiving the power amplifier initialization request, the power amplifier performs initialization operation, and feeds back a corresponding enable signal to the multimedia resource acquisition device after the initialization operation is successfully performed, wherein the enable signal is 0xc 0.
After receiving the enable signal, the multimedia resource obtaining device determines whether the power amplifier successfully performs the initialization operation according to the enable signal, and if so, sends an audio description request (request audio description) to the power amplifier, where the audio description request may be, for example, 0xa 4.
After receiving the audio description request, the power amplifier sends feedback information including the second attribute information to the multimedia resource obtaining device, where each specific second attribute information may be carried in the feedback information in a data block (response block) manner, where the feedback signal may be, for example, 0xa3, and each data block corresponds to different decoding capability information supported by the power amplifier. Because there may be multiple audio formats in which the power amplifier can perform audio decoding, the multiple data blocks respectively carry second attribute information, for example, if the second attribute information is 3, the feedback information may include three blocks, which are respectively block [0, 1, 2], that is, block [0-2], and the information encapsulated in each block is one audio format in which the power amplifier can perform audio decoding and the maximum number of channels corresponding to the audio format.
Example 3:
to further determine a processing method for a first audio, on the basis of the foregoing embodiments, the determining, according to the first attribute information and the second attribute information, the processing method for the first audio includes:
judging whether the second attribute information is matched with the first attribute information;
if so, determining not to process the first audio;
and if not, determining a processing method of the first audio according to third attribute information and the second attribute information corresponding to each encoding and decoding processing mode supported by the first audio.
In order to avoid the situation that the audio playing device cannot play the audio and improve the quality of the audio played by the audio playing device, after the multimedia resource obtaining device obtains the first attribute information and the second attribute information, it may be determined whether the second attribute information matches the first attribute information. If the second attribute information is matched with the first attribute information, the audio playing device can process and play the first audio after the first audio is directly sent to the audio playing device. If the first audio is not matched with the second audio, the audio playing device is indicated to be incapable of processing and playing the first audio, at this time, the first audio needs to be correspondingly processed at the multimedia resource obtaining device end, the audio processed as the audio capable of being processed and played by the audio playing device is sent to the audio playing device, and the audio playing device is enabled to process and play the processed first audio.
Specifically, the determining whether the second attribute information matches the first attribute information includes:
judging whether a target second audio format with the grade not lower than that of the first audio format exists in the second audio formats, wherein the number of the first channels is not more than that of the second channels corresponding to the target second audio format;
if so, determining that the second attribute information is matched with the first attribute information;
otherwise, determining that the second attribute information does not match the first attribute information.
Because the second audio formats corresponding to the power amplifier in the audio playing device generally exist in multiple types, that is, the second attribute information exists in multiple types, the multimedia resource obtaining device needs to judge whether at least one target second audio format exists in the second audio formats and is higher than or equal to the first audio format of the first audio to be output, if so, in order to judge whether the audio playing device can process the first audio more accurately, whether the number of channels corresponding to the at least one target second audio format exists is more than the number of first channels needs to be further judged, and if so, the second attribute information is matched with the first attribute information; if not, the second attribute information is not matched with the first attribute information.
If the second attribute information is matched with the first attribute information, the power amplifier in the audio playing device can directly decode the first audio to be output, and the multimedia resource obtaining device does not need to perform re-encoding and decoding processing on the first audio, so that the multimedia resource obtaining device can directly send the first audio to the power amplifier, and the power amplifier outputs the first audio after decoding processing is performed on the first audio.
Specifically, after receiving the first audio, a power amplifier in the audio playing device first identifies first attribute information corresponding to the first audio, that is, first identifies a first audio format and a channel number corresponding to the first audio, then determines a decoding mode corresponding to the first attribute information, and decodes and outputs the first audio according to the decoding mode.
For example, the first audio format of the first audio is Dolby Digital Plus 5.1, the number of channels corresponding to the first audio format is 6, and the second audio format of the power amplifier includes: dolby Digital Plus 7.1, the number of channels corresponding to the second audio format is 8 channels, the level of Dolby Digital Plus 7.1 is higher than that of Dolby Digital Plus 5.1, and the 8 channels are greater than 6 channels, so that the multimedia resource acquisition equipment can directly send the first audio with the audio format of Dolby Digital Plus 5.1 to the power amplifier. After the power amplifier receives the first audio, first attribute information of the first audio is identified, and the audio format of the first audio is known to be a Dolby Digital Plus 5.1, 6 channel, so that the first audio is decoded according to a decoding mode corresponding to the audio format, and a second audio with the 6 channel format of the Dolby Digital Plus 5.1 is obtained and played.
If a target second audio format with a grade not lower than that of the first audio format does not exist in the second audio format, and/or the number of the first channels is not greater than that of the second channels corresponding to the target second audio format, it is indicated that the second attribute information is not matched with the first attribute information, and the multimedia resource acquisition device needs to determine a processing method for the first audio according to third attribute information corresponding to each coding and decoding processing mode supported by the multimedia resource acquisition device and second attribute information corresponding to the power amplifier.
In order to determine the processing method of the first audio more accurately, if the second attribute information does not match the first attribute information, the determining the processing method of the first audio according to the third attribute information and the second attribute information corresponding to each codec processing method supported by the determining method includes:
judging whether target third attribute information matched with the second attribute information exists in the third attribute information or not;
and if so, carrying out coding and decoding processing on the first audio according to the target third attribute information.
Since the multimedia resource acquiring device can support multiple encoding and decoding processing modes, if the multimedia resource acquiring device is required to process the first audio to be output, the multimedia resource acquiring device can perform encoding and decoding of the multiple modes again on the audio format of the first audio to be output, so as to obtain the processed first audio in multiple encoding formats and channel numbers, that is to say, the third attribute information corresponding to the first audio after encoding and decoding is different. In order to better determine the processing method for the first audio, the multimedia resource acquiring device needs to determine whether there is target third attribute information matching the second attribute information in the third attribute information.
Specifically, the determining whether there is target third attribute information matching the second attribute information in the third attribute information includes:
judging whether the grade of a third audio format of the target third attribute information is not higher than the grade of at least one second audio format in the second attribute information, wherein the number of channels corresponding to the third audio format is not more than the number of channels corresponding to the at least one second audio format;
if yes, determining that target third attribute information matched with the second attribute information exists in the third attribute information;
otherwise, determining that the third attribute information does not have target third attribute information matched with the second attribute information.
Specifically, when determining whether the third attribute information matches the second attribute information, if the third attribute information matches the second attribute information, there may be a plurality of target third attribute information matching the second attribute information in the third attribute information, and the codec mode corresponding to each third attribute information may be different. The multimedia resource obtaining equipment can randomly select one target third attribute information from the target third attribute information, carry out coding and decoding processing on the first audio according to the target third attribute information, and send the processed first audio to the power amplifier so that the power amplifier decodes and outputs the processed first audio; for example, the audio format of the target third attribute information selected by the multimedia resource obtaining device is PCM, the number of channels is 2, the multimedia resource obtaining device performs encoding and decoding on the first audio to obtain PCM audio with the number of channels being 2, and sends the PCM audio to the power amplifier, the power amplifier identifies the attribute information corresponding to the PCM audio, determines the decoding mode corresponding to the attribute information, and after performing decoding processing on the PCM audio according to the decoding mode, the audio playing device carrying the power amplifier can normally play the PCM audio.
In order to further improve the playing quality of the audio, the encoding and decoding the first audio according to the target third attribute information includes:
determining target attribute information corresponding to a third audio format with the highest grade in the target third attribute information;
and carrying out coding and decoding processing on the first audio according to the target attribute information.
Because there may be a plurality of target third attribute information, and each target third attribute information corresponds to a different encoding and decoding manner, in order to further improve the quality of the audio played by the audio playing device and further enable the user to obtain the best hearing experience, the specific method for the multimedia resource acquiring device to determine the target attribute information may be to compare the levels of the third audio formats in each target third attribute information, determine the target third audio format with the highest level, and then determine the target third attribute information corresponding to the target third audio format with the highest level as the target attribute information. The multimedia resource obtaining device determines the target attribute information, that is, determines a target coding and decoding processing mode corresponding to the target attribute information, and then may perform coding and decoding processing on the first audio according to the target coding and decoding processing mode.
After receiving the first audio after the encoding and decoding, the power amplifier first identifies attribute information corresponding to the first audio after the encoding and decoding, wherein the attribute information includes an audio format and a channel number corresponding to the first audio after the encoding and decoding, so that the first audio after the encoding and decoding is decoded and output.
Assuming that the third audio format in the target third attribute information includes three of Dolby Digital Plus 5.1, and Dolby Digital Plus 2.0, where the Dolby Digital Plus 5.1 has the highest rank, the target third attribute information corresponding to Dolby Digital Plus 5.1 is taken as the target attribute information, and the first audio format of the first audio is Dolby Digital Plus 7.1, the number of channels corresponding to the first audio format is 8, or the first audio format of the first audio is DTS5.1, and the number of channels corresponding to the first audio format is 6, so that the multimedia resource acquiring device may re-encode and decode the first audio having the audio format of Dolby Digital Plus 7.1 or DTS5.1 into the audio format of Dolby Digital Plus 5.1, output the audio having the number of channels of 6 to the audio power amplifier, and decode the audio power amplifier into the third audio of Dolby using the third audio amplifier, and obtain the decoded audio of the third audio format of Dolby the Dolby Digital Plus 5.1, thereby, the audio playing device plays the third audio to make the user obtain the best hearing experience.
If the third attribute information is not matched with the second attribute information, it is indicated that target third attribute information matched with the second attribute information does not exist in the third attribute information, and the multimedia resource obtaining device cannot obtain audio which can be coded and decoded by the power amplifier through a corresponding coding and decoding mode. At this time, the multimedia resource acquiring device needs to further determine whether it can decode and play the first audio to be output.
Specifically, if there is no target third attribute information matching the second attribute information in the third attribute information, the method further includes:
judging whether fourth attribute information matched with the first attribute information exists in the third attribute information or not;
if yes, decoding and playing the first audio according to the fourth attribute information.
Specifically, when it is determined whether the third attribute information matches the first attribute information, if so, it indicates that the multimedia resource acquisition device can decode the first audio to be output. Specifically, the multimedia resource acquiring device determines a decoding mode corresponding to the fourth attribute information according to the fourth attribute information, and decodes the first audio according to the decoding mode to obtain a fifth audio, so that an audio playing module carried by the multimedia resource acquiring device plays the fifth audio.
