Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Fig. 1 is the flow chart of the audio output method of adjustment in one embodiment.The method of adjustment comprises the following steps：
S10：Detect and obtain the decoding capability for the ancillary equipment being connected with audio-video terminal.
During audio output, audio output effect is directly related with the decoding capability of ancillary equipment, if output
Audio types are the types that ancillary equipment decoding capability can be supported, then can reach best output effect.If for example, output
Be DOLBY (Doby) audio, ancillary equipment decoding capability supports DOLBY decodings, then can export best output effect；If
Ancillary equipment decoding capability does not support DOLBY to decode, and only supports PCM decodings, if what is continued to output is DOLBY audios, then can
Influence audio frequency effect.Therefore when ancillary equipment connects audio-video terminal, the decoding capability of ancillary equipment is obtained, to ancillary equipment
Decoding capability understood, be conveniently adjusted the type of audio output.
In the embodiment, the decoding capability of ancillary equipment includes：Support that (pulse code is adjusted by decoding DOLBY audio types and PCM
System) audio types or only support decoding pcm audio type.
S20：The audio-frequency information of actual program is detected, judges whether actual program has auxiliary audio frequency, if with auxiliary sound
Frequently, then the type of auxiliary audio frequency and the mixed relationship with main view frequency are obtained.
When audio-video terminal plays program, due to the audio-frequency informations of different programs, there is difference, some programs to have
Auxiliary audio frequency, some programs do not have auxiliary audio frequency, and auxiliary audio frequency may also be different with main audio type and mixed relationship, need
Different audio output is carried out to different auxiliary audio frequencies to adjust, it is defeated with the audio for reaching best with adaptive ancillary equipment
Go out effect.
In this embodiment, step S20 is specially：Detection mark is set to auxiliary audio frequency respectively, to main audio type
Main audio type identification is set, sets auxiliary audio frequency type identification and main audio and auxiliary audio frequency to mix auxiliary audio frequency type
Conjunction relation sets mixed relationship to identify.
The sound of mark, main audio type identification, auxiliary audio frequency type identification and mixed relationship mark insertion program will be detected
In frequency information.
Detect and the detection mark in program audio information, main audio type identification, auxiliary audio frequency type identification and
Mixed relationship identifies, and judges whether actual program has auxiliary audio frequency, if having auxiliary audio frequency, obtains the type of auxiliary audio frequency
And the mixed relationship with main view frequency.
Specifically, setting detection mark to auxiliary audio frequency, if auxiliary audio frequency be present, the first detection mark is arranged to, if
The second detection mark is then arranged in the absence of auxiliary audio frequency.Main audio type identification is set to main audio type, if main audio is
DOLBY audio types, then the first main audio type identification is arranged to, if pcm audio type, is then arranged to the second main audio class
Type identifies.Auxiliary audio frequency type identification is set to auxiliary audio frequency type, if auxiliary audio frequency is DOLBY audio types, is arranged to
First auxiliary audio frequency type identification, if pcm audio type, then it is arranged to the second auxiliary audio frequency type identification.To main audio with
The mixed relationship of auxiliary audio frequency sets mixed relationship to identify, if being mixed audio with main audio, is arranged to mixed relationship mark,
If being not mixed audio (i.e. both are each independent, are independent audio) with main audio, then not mixed relationship mark is arranged to.
Such as：A usual program has one or more main audio, for example we watch CCTV1, current master
Audio have audio format corresponding to tetra- kinds of main audios of CHINESE, ENGLISH, FRENCH, GERMAN be respectively DOLBY audios,
Pcm audio, DOLBY audios and DOLBY audios, user can switch main audio when program is watched.Except main audio, have
TV programme are watched for the ease of blind person by possible operator, to three kinds of auxiliary audio frequencies corresponding to first three main audio increase, difference
For CHINESE-AD, ENGLISH-AD, FRENCH-AD, these three auxiliary audio frequencies also exist in program audio, and they
Audio format is DOLBY audios, pcm audio and DOLBY audios.Mixed relationship with respective main audio is respectively：Mix keynote
Frequently, not mixed audio, not mixed audio.It is assumed that auxiliary audio frequency be present is identified as 1, in the absence of being identified as 0；The type of main audio is
PCM is denoted as 1, DOLBY and is denoted as 2；The type of same auxiliary audio frequency is denoted as 1 for PCM, and Dolby Audio is denoted as 2, aids in sound
Frequency and main audio are that mixed audio is denoted as 1, do not mix and are denoted as 2, then obtain the data structure of one：CHINESE：1、2、2、
1；ENGLISH：1、1、1、2；FRENCH：1、2、2、2；GERMAN：0、2、0、2.Data structure is inserted into program audio information
In, then the data structure detected in program audio information can determine that.
Further, if step S20 also includes：If not having auxiliary audio frequency, the audio types of main audio are processed into
The type that ancillary equipment decoding capability can be supported, is output to ancillary equipment.To main audio according to ancillary equipment decoding capability from
The adjustment output of adaptation.For example, if main audio is DOLBY audio types, if ancillary equipment only supports pcm audio type, incite somebody to action
The adaptive processing of main audio is pcm audio type so that ancillary equipment can be supported, improve output audio frequency effect.
S30：If auxiliary audio frequency is not mixed audio with main audio, according to the decoding capability of ancillary equipment, by main audio
The same type that ancillary equipment decoding capability can support is processed into auxiliary audio frequency.
After a test, do not mixed if there is auxiliary audio frequency and with main audio, if by auxiliary audio frequency and main audio list
Solely output, then can influence audio output effect, it is necessary to which auxiliary audio frequency is mixed with main audio.Due to auxiliary audio frequency and keynote
Frequency type may be different, and it is same type to first have to auxiliary audio frequency and main audio processing, while again can be by ancillary equipment
Decoding capability support.
In this embodiment, step S30 is specially：
If ancillary equipment supports decoding DOLBY audio types and pcm audio type, if main audio is pcm audio type,
Auxiliary audio frequency is DOLBY audio types, then is pcm audio type by auxiliary audio frequency processing, if main audio is DOLBY audio class
Type, then main audio and auxiliary audio frequency being processed into pcm audio type, (most audio-video terminal does not support two-way DOLBY audios
Or DOLBY audios pcm audio all the way all the way)；
If ancillary equipment is only supported to decode pcm audio type, main audio and auxiliary audio frequency are processed into pcm audio
Type.
In addition, step S30 also includes：If auxiliary audio frequency and main audio are mixed audio, mixed audio is processed into
The type that ancillary equipment decoding capability can be supported, is output to ancillary equipment.It can adapt to outside with causing mixed audio to be adjusted to
The type that peripheral equipment is supported.
S40：Main audio after processing and auxiliary audio frequency are mixed, mixed audio is formed and is output to ancillary equipment.
After handling the audio types of main audio and auxiliary audio frequency, the main audio after processing and auxiliary audio frequency are entered
Row mixing, form mixed audio and be output to ancillary equipment again, because ancillary equipment can be good at supporting decoding, so that section
Purpose audio output reaches best effect.
For example, it is assumed that what is accessed at present is A ancillary equipment, decoding DOLBY audio types and pcm audio type are supported.
When user is switched to CHINESE audios, now main audio and auxiliary audio frequency are DOLBY audios and are
Mixed audio, optimal audio output mode is that mixing DOLBY audios directly passthrough transparent transmissions can export, so defeated
It is optimal to go out DOLBY audios.
When user is switched to ENGLISH audios, now main audio and auxiliary audio frequency are pcm audio and are single
Only audio, optimal mode is to mix single main audio and auxiliary audio frequency and be arranged to PCM outputs, so output
Pcm audio is optimal.
When user is switched to FRENCH audios, current main audio and auxiliary audio frequency be all DOLBY audios and
Single audio, due to passthorugh transparent transmissions while part audio-video terminal can not handle two-way DOLBY audios, also not
Support will all the way audio passthrough transparent transmissions all the way audio dowmnix into pcm audio, therefore can only by main audio and auxiliary sound
Then two-way audio is carried out mixing output pcm audio, so output pcm audio is optimal by frequency downmix into pcm audio.
Assuming that what is accessed at present is B ancillary equipment, pcm audio type is only supported.
Because B ancillary equipment only supports PCM audio decoder form, so no matter which kind of main audio user is switched to, all
Need main audio with auxiliary audio frequency downmix into pcm audio, and main audio and auxiliary audio frequency are subjected to mixing output (PCM sounds
Frequency type hybrid audio or need not handle in the absence of auxiliary audio frequency) into pcm audio, so output pcm audio is optimal.
Further, since auxiliary audio frequency is set for special personage, to allow users to independently choose whether using auxiliary
Audio is helped, this method also includes：Auxiliary audio frequency switching function is set, so that user opens or closed as needed auxiliary sound
Frequently.If user closes auxiliary audio frequency, go to handle main audio according to the pattern of no auxiliary audio frequency.
The audio output method of adjustment, obtain ancillary equipment decoding capability and automatic detection program audio in whether there is
Auxiliary information, the mixed relationship if it auxiliary audio frequency be present according to the type of auxiliary audio frequency and with main view frequency, auxiliary audio frequency with
Main audio for not mixed audio when by main audio and auxiliary audio frequency be processed into ancillary equipment decoding capability can support it is mutually similar
Type, then mixed, being automatically regulated to be can be by the mixed audio that ancillary equipment is supported and output effect is best, and audio is defeated
Go out to ancillary equipment, it is not necessary to which user carries out any setting, simple and convenient, avoids user misoperation from causing without complete
