For following several situations：
The first situation：
When not including video data in the PMT of target channel but including audio data, the video mark in indicating hyte
Addition is without video data identification in will position.Specifically, can be after the PMT to target channel is parsed, detection is obtained by PMT
Whether there is no data information and the Aud i oL i that are obtained by PMT in the Vi deoL i st (video lists catalogue) taken
It whether there is data information in st (audio lists catalogue), if being to be, then it is assumed that do not include video data in the PMT but include
Audio data, and addition obtains corresponding broadcasting flag bit without video data identification in the video flag bit in indicating hyte
Group.
The second situation：
When not including audio data in the PMT of target channel but including video data, the audio mark in indicating hyte
Addition is identified without audio data in will position.Specifically, can be after the PMT to target channel is parsed, detection is obtained by PMT
In the Aud i oL i st taken whether in the Vi deoL i st obtained there is no data information and by PMT with the presence or absence of counting
It is believed that breath, if being to be, then it is assumed that do not include audio data in the PMT but include video data, and the sound in indicating hyte
Addition is identified without audio data in frequency flag bit, obtains corresponding broadcasting mark hyte.
The third situation：
Similarly, when application above-mentioned steps confirm target channel PMT in both do not include audio data and also do not include video counts
According to when, then addition identifies and video mark in indicating hyte without audio data in the audio signature position in indicating hyte
Addition is without video data identification in position, and obtains corresponding broadcasting mark hyte.
It should be noted that in specific application scenarios, the application can be according to entrained sound in the PMT of target channel
The corresponding behaviour of one of which of the three kinds of situations referred in above-mentioned first way is individually performed in the quantity of video data type
Make.The corresponding operation of the above situation how is specifically executed, the protection domain of the application can't be influenced.
It is further alternative, when in the PMT according to target channel audio data information and video data information indicating
Corresponding mark is added in hyte and is obtained after playing mark hyte, which can be passed through RPC (Remote
Procedure Ca l l remote procedure call protocols) it is sent in the middleware layer of playing device, and detected by middleware layer
The identification information carried in the broadcasting mark hyte.
Further, three kinds referred in for above-mentioned first way, S103 in the application is (according to broadcasting
Put the content that flag bit group plays target channel), according to the concrete operation step for playing flag bit broadcasting target channel content
In, correspond to three kinds of situations in first way, can be handled as follows respectively：
Corresponding to the first situation in first way：
When detecting in the broadcasting mark hyte there is only when no video data identification, then it is arranged and shape is played to current video
State is persistently to forbid broadcast state, and then the audio data in channel PMT is sent in player.It is determined in middleware layer
Current video broadcast state is after persistently forbidding broadcast state, to release the instruction for stopping playing sound, and then play the channel
Voice data content.Wherein, it should be noted that, can also be first to user before the voice data content for playing the channel
It is to be only capable of the notice of playing audio-fequency data content channel to send target channel.
Corresponding to the second situation in first way：
When detect identified there is only no audio data in the broadcasting mark hyte when, then setting to present video play shape
State is persistently to forbid broadcast state, and then the video data in channel PMT is sent in player.It is determined in middleware layer
Present video broadcast state is after persistently forbidding broadcast state, to release the instruction for stopping playing video, and then play the audio
Voice data content.Wherein, also need explanation, play the channel video data content before, can also first to
It is to be only capable of the notice of playing video data content channel that user, which sends target channel,.
Corresponding to the third situation in first way：
When detecting in the broadcasting mark hyte both in the presence of no audio data mark there is also when no video data identification, then
Judge that the channel is no video data content and the not no channel of audio data content, being sent then to user can not play
The notice of target channel content, and no longer any processing is done for the channel.
It should be noted that in video data content or audio number according to above-mentioned three kinds broadcasting target channels
Before content, it can also detect first and currently whether there is audio-video frequency content being played on, such as boot animation, it is long-range to record
As picture, USB video contents etc. such as detect that there is currently when audio-video frequency content being played on, can select first to stop broadcasting
Current audio-video frequency content is put, and after the preset time for stopping playing current audio-video frequency content, starts to play the interior of target channel
Hold.Further, the application can also be when detecting there is currently when audio-video frequency content being played on, according to currently playing
Audio-video frequency content classification and target channel data content, choose whether to need first to stop playing in current audio and video
Hold, and after the preset time for stopping playing current audio-video frequency content, starts the content for playing target channel.For example, working as target
Channel before the audio data content for playing target channel, is detected and is currently played there is only when audio data content
Start-up picture.At this point, terminating the broadcasting of start-up picture, and after terminating the preset time that start-up picture plays, play target frequency
The audio data content in road.The audio data content of start-up picture and target channel is mistakenly considered to avoid user same whole
Content.
The second way：
Specifically, after to the PMT of target channel parsing, judged according to analysis result in the PMT of the channel whether
Including video data and audio data.And to the mark hyte in the case of in the PMT of the channel comprising audio, video data
In video flag bit addition it is corresponding mark and/or corresponding mark is added in audio signature position, further, addition pair
Mark hyte after should identifying is to play mark hyte.
Wherein, corresponding mark is added in indicating hyte, obtains playing in the second way for indicating hyte, Ke Yifen
For following several situations：
The first situation：
When only including video data in PMT, video data identification is added in video flag bit.Specifically, can be
After being parsed to the PMT of target channel, whether data information is not present in the Aud i oL i st that detection is obtained by PMT
And whether there is data information in the Vi deoL i st obtained by PMT, if being to be, then it is assumed that only include to regard in the PMT
Frequency evidence, and then video data identification is added in the video flag bit of mark hyte, obtain corresponding broadcasting mark hyte.
The second situation：
When only including audio data in PMT, audio data mark is added in audio signature position.Specifically, can be
Whether be not present after the PMT of target channel parsing, in the Vi deoL i st that detection is obtained by PMT data information and
It whether there is data information in the Aud i oL i st obtained by PMT, if being to be, then it is assumed that only include audio in the PMT
Data, and then the addition audio data mark in the audio signature position of mark hyte obtain corresponding broadcasting mark hyte.
The third situation：
Similarly, when application above-mentioned steps, which confirm in the PMT of target channel, both to have been included video data or included audio data,
Audio data mark is then added in the audio signature position in indicating hyte and is added in the video flag bit in indicating hyte
Add video data identification, and obtains corresponding broadcasting mark hyte.
It should be noted that in specific application scenarios, the application can be according to entrained sound in the PMT of target channel
The corresponding behaviour of one of which of the three kinds of situations referred in the above-mentioned second way is individually performed in the quantity of video data type
Make.The corresponding operation of the above situation how is specifically executed, the protection domain of the application can't be influenced.
It is further alternative, when in the PMT according to target channel audio data information and video data information indicating
Corresponding mark is added in hyte and is obtained after playing mark hyte, which can be passed through RPC (Remote
Procedure Ca l l remote procedure call protocols) it is sent in the middleware layer of playing device, and detected by middleware layer
The identification information carried in the broadcasting mark hyte.
Further, three kinds referred in for the above-mentioned second way, S103 in the application is (according to broadcasting
Put the content that flag bit group plays target channel), according to the concrete operation step for playing flag bit broadcasting target channel content
In, correspond to three kinds of situations in the second way, can be handled as follows respectively：
Corresponding to the first situation in the second way：
When detecting that there is only present video broadcast state when video data identification, is then arranged to be in the broadcasting mark hyte
Persistently forbid broadcast state, then the video data in channel PMT is sent in player.It is determined in middleware layer current
Audio broadcast state is after persistently forbidding broadcast state, to release the instruction for stopping playing video, and then play the video of the channel
Data content.Wherein, explanation is also needed, it, can also be first to user before the video data content for playing the channel
It is to be only capable of the notice of playing video data content channel to send target channel.
Corresponding to the second situation in the second way：
When detecting that current video broadcast state, which is then arranged, is when being identified there is only audio data in the broadcasting mark hyte
Persistently forbid broadcast state, then the audio data in channel PMT is sent in player.It is determined in middleware layer current
Video broadcasting condition is after persistently forbidding broadcast state, to release the instruction for stopping playing sound, and then play the sound of the channel
Data content.Wherein, it should be noted that before the voice data content for playing the channel, can also first be sent to user
Target channel is to be only capable of the notice of playing audio-fequency data content channel.
Corresponding to the third situation in the second way：
When detecting that both there is video data identification in the broadcasting mark hyte identifies there is also audio data, then judge
The target channel is the channel with video data content and audio data content, then by regarding in the PMT of target channel
Frequency is according to this and audio data is sent in player, after player synchronizes video data and audio data progress AV, to
Middleware layer sends AV and synchronizes completed notice.Stop playing video so that middleware layer after receiving the notice, releases
With the instruction of sound, and then the video data content and audio data content of the channel are played.
Explanation is also needed, in the video data content or sound according to above-mentioned three kinds broadcasting target channels
Before frequency data content, it can also detect first and currently whether there is audio-video frequency content being played on, such as boot animation, far
Journey video frames, USB video contents etc. such as detect that there is currently when audio-video frequency content being played on, can select first to stop
Current audio-video frequency content is only played, and after the preset time for stopping playing current audio-video frequency content, starts to play target channel
Content.Further, the application can also be when detecting there is currently when audio-video frequency content being played on, according to current
