If so, determining to first audio without processing；
If not, being belonged to according to the corresponding third attribute information of every kind of encoding and decoding processing mode and described second itself supported Property information, determine to the processing method of first audio.
The case where audio can not be played in order to avoid audio-frequence player device generation, and improve audio-frequence player device and play audio Quality, when multimedia resource obtain equipment get above-mentioned first attribute information and the second attribute information after, can first judge Whether second attribute information matches with first attribute information.Because if the second attribute information and first attribute information Match, then after illustrating that first audio is transmitted directly to audio-frequence player device, which is able to carry out processing and plays. If it does not match, illustrating that the audio-frequence player device cannot be handled and be played to the first audio, needed at this time in multimedia Resource acquisition equipment end performs corresponding processing first audio, handles the sound for being capable of handling and playing for audio-frequence player device Frequency is then forwarded to audio-frequence player device, and making the audio-frequence player device to treated, the first audio handled and played.
Specifically, described to judge whether second attribute information matches with first attribute information and include:
Judge in second audio format with the presence or absence of the target second of the grade not less than first audio format Audio format, and first channel number is not more than the corresponding second sound channel number of the target second audio format；
If it is present determining that second attribute information is matched with first attribute information；
Otherwise, it determines second attribute information and first attribute information mismatch.
Since corresponding second audio format of power amplifier is generally there are a variety of in audio-frequence player device, i.e., the second attribute information is deposited A variety of, multimedia resource obtains equipment needs and judge to whether there is at least one target second in these the second audio formats Audio format is greater than or equal to the first audio format of the first audio to be output, if so, in order to more accurately judge sound Whether frequency playback equipment can be handled first audio, then needs further to judge at least one existing target second Whether the corresponding channel number of audio format is greater than the first channel number, if it is, the second attribute information of explanation and first attribute Information matches；If it is not, then the second attribute information of explanation and first attribute information mismatch.
If the second attribute information is matched with first attribute information, the power amplifier in audio-frequence player device can be treated directly First audio of output is decoded, and is not needed multimedia resource acquisition equipment and is carried out at encoding and decoding again to first audio Reason, therefore, multimedia resource, which obtains equipment, to be directly sent to the power amplifier for first audio, by the power amplifier to first sound Frequency exports after being decoded processing.
Specifically, after the power amplifier in audio-frequence player device receives first audio, first identify that first audio is corresponding The first attribute information, i.e., first identify corresponding first audio format of first audio and channel number, then determine this first belong to The property corresponding decoding process of information, is decoded output to first audio according to the decoding process.
For example, the first audio format of first audio is Dolby Digital Plus 5.1, first audio format Corresponding channel number is 6 sound channels, and the second audio format of the power amplifier includes: Dolby Digital Plus 7.1, second sound The corresponding channel number of frequency format is 8 sound channels, the grade ratio Dolby Digital Plus of Dolby Digital Plus 7.1 5.1 grade is high, and 8 sound channels are greater than 6 sound channels, and therefore, multimedia resource, which obtains equipment, to be directly Dolby by audio format The first audio of Digital Plus 5.1 is sent to the power amplifier.After power amplifier receives first audio, first identify this first First attribute information of audio knows that the audio format of first audio is 5.1,6 sound channel of Dolby Digital Plus, because This is decoded first audio according to the corresponding decoding process of the audio format, and obtaining 6 channel formats is Dolby The second audio of Digital Plus 5.1 simultaneously plays.
If the target second audio format in second audio format there is no grade not less than first audio format, And/or first channel number is not more than the corresponding second sound channel number of the target second audio format, illustrates second attribute information It is mismatched with first attribute information, multimedia resource obtains every kind of encoding and decoding processing mode that equipment needs to support according to itself Corresponding third attribute information and corresponding second attribute information of the power amplifier determine the processing method to first audio.
In order to more accurately determine to the processing method of first audio, if second attribute information and described the When one attribute information mismatches, the corresponding third attribute information of every kind of encoding and decoding processing mode supported according to itself and institute The second attribute information is stated, determination includes: to the processing method of first audio
Judge to believe in the third attribute information with the presence or absence of with the matched target third attribute of second attribute information Breath；
If it does, carrying out encoding and decoding processing to first audio according to the target third attribute information.
Since multimedia resource obtains the encoding and decoding processing mode that can support of equipment itself there are a variety of, so if needing It wants multimedia resource to obtain equipment to handle the first audio to be output, then it can be to the audio of the first audio to be output Format re-starts the encoding and decoding of various ways, so that a variety of coded formats and channel number are obtained treated the first audio, That is treated that the corresponding third attribute information of the first audio is different for encoding and decoding.In order to preferably determine to first The processing method of audio, multimedia resource obtain equipment and need to judge to whether there is and second attribute in the third attribute information The target third attribute information of information matches.
Specifically, whether there is and the matched target of the second attribute information in the judgement third attribute information Third attribute information includes:
Judge whether the grade of the third audio format of the target third attribute information is not higher than the second attribute letter The grade of the second audio format of at least one in breath, and the corresponding channel number of the third audio format is no more than described at least one A corresponding channel number of the second audio format；
Exist and the matched target third category of second attribute information if it is, determining in the third attribute information Property information；
Otherwise, it is determined that be not present and the matched target third category of second attribute information in the third attribute information Property information.
Specifically when judging whether third attribute information matches with the second attribute information, if it does, may third attribute With the matched target third attribute information of the second attribute information there may be multiple in information, and because of each third attribute information Corresponding code encoding/decoding mode all may be different.Multimedia resource obtains equipment can be any in these target third attribute informations A target third attribute information is selected, encoding and decoding processing is carried out to first audio according to the target third attribute information, and By treated, the first audio is sent to power amplifier, so that the power amplifier is to treated, the first audio is decoded output；Such as it is more The audio format that media resource obtains the target third attribute information that equipment selects is PCM, and channel number 2, multimedia resource obtains It takes equipment to carry out encoding and decoding to first audio and obtains channel number as 2 pcm audio, and the pcm audio is sent to power amplifier, it should Power amplifier identifies the corresponding attribute information of the pcm audio, the corresponding decoding process of the attribute information is determined, according to the decoding process After being decoded processing to the pcm audio, so that the audio-frequence player device for carrying the power amplifier can be with the normal play pcm audio.
It is described according to the target third attribute information in order to further increase the play quality of audio, to described first Audio carries out encoding and decoding processing
Determine the corresponding target property information of the highest third audio format of target third attribute information middle grade；
According to the target property information, encoding and decoding processing is carried out to first audio.
Because target third attribute information is there may be multiple, and each target third attribute information corresponds to different volumes Decoding process plays the quality of audio to further increase audio-frequence player device, and then user is made to obtain optimal sense of hearing body It tests, multimedia resource obtains equipment and determines that the specific method of the target property information can be first to each target third attribute letter The grade of third audio format in breath is compared, and the highest target third audio format of grade is determined, then by the grade The corresponding target third attribute information of highest target third audio format is determined as target property information.Multimedia resource obtains Equipment has determined the target property information, that is, the corresponding target encoding and decoding processing mode of the target property information has been determined, then Encoding and decoding processing can be carried out to first audio according to the target encoding and decoding processing mode.
After the power amplifier receives above-mentioned encoding and decoding treated the first audio, the encoding and decoding are first identified treated the first sound Frequently corresponding attribute information, the attribute information include the encoding and decoding treated the corresponding audio format of the first audio and sound channel Number, so that treated that the first audio is decoded output to the encoding and decoding.
Assuming that the third audio format in target third attribute information includes Dolby Digital Plus 5.1, Dolby Digital 5.1, Dolby Digital 2.0 these three, wherein the grade highest of Dolby Digital Plus 5.1, will The corresponding target third attribute information of Dolby Digital Plus 5.1 is as target property information, and the of first audio One audio format is Dolby Digital Plus 7.1, which is 8 or first audio The first audio format be DTS5.1, the corresponding channel number of the first audio format be 6, therefore, multimedia resource obtain equipment Can by audio format be Dolby Digital Plus 7.1 or DTS5.1 the first audio again encoding and decoding at audio format For Dolby Digital Plus 5.1, channel number be 6 audio output to power amplifier, after which receives the audio, use 5.1 format of Dolby Digital Plus obtains third audio to the audio decoder, thus make audio-frequence player device play this Three audios, to make user obtain optimal audio experience.
