Description
Technical field
The present invention discloses a kind of method handling video-audio data and relevant module, and espespecially a kind of DTV can correspond to not
The method for handling video-audio data that is co-channel next while providing different voice data streams to multiple mobile devices to play out
And the module of application this method.
Background technology
Occurs the divided frame (Picture-in-picture, PIP, also known as picture screen) of a part on the market at present
DTV, function, which essentially consists in, in a manner of divided frame while to play the sections of two or more channels on single screen
Purpose picture.Due to the picture for the program that can play multiple and different channels simultaneously, divided frame DTV would generally have compared with
The larger sized screen of general domestic TV, such as outdoor video wall.
However, although general divided frame DTV can play the picture of multiple programs simultaneously, but can not
The audio of those programs is played simultaneously, and in other words, general divided frame DTV is to play those in a manner of monophonic
The audio stream (being typically the audio stream of mother picture subordinate channel) of one of program in program.Therefore, there is multiple make when simultaneously
When user watches the different program pictures on same divided frame DTV, the user for only watching mother picture is able to simultaneously
Hear the audio for the program that it to be watched, and the user for watching other sprites is then merely able to watch the program that it to be watched
Picture.
Invention content

Control module 140 is used for each by multiple mobile device 150A, 150B, 150C in a wired mode or wireless mode
From reception selection instruction SEL1, SEL2, SEL3, and respectively corresponds to each selection instruction and generate a first control signal and one second
Control signal, the wherein first control signal can be transmitted to decoder 110 by control module 140, with indicate decoder 110 into
The decoded mode of row, and the second control signal can be transmitted to data transmission module 130 by control module 140, with designation date
The mode that transmission module 130 carries out data transmission.Selection instruction SEL1, SEL2, SEL3 are respectively used for selecting the DTV institute
One of the multiple channels provided channel.For example with Fig. 1, control module 140 can corresponding selection instruction SEL1 generations
An one first control signal C11 and second control signal C12, corresponding selection instruction SEL2 generate a first control signal C21 with
One second control signal C22, corresponding selection instruct SEL3 to generate an a first control signal C31 and second control signal C32.
In one embodiment of the invention, control module 140 can be according further to the configuration specified by selection instruction SEL1, SEL2 or SEL3
Setting changes configuration mode when display device 120 shows each divided frame.
A channel of the meeting of decoder 110 indicated by the first control signal, more than one that module 100 is received by outside
The video flowing and audio stream corresponding to the channel are decoded in media data flow MS.For Fig. 1, decoder 110 can be by first
Control a corresponding video flowing VS1 and audio stream AS1 in multimedia data stream MS of one first channel indicated by signal C11
Decode come, by one second channel indicated by first control signal C12 in multimedia data stream MS a corresponding video flowing
A VS2 and audio stream AS2 decode come, by the third channel indicated by first control signal C13 in multimedia data stream MS
In a corresponding video flowing VS3 and audio stream AS3 decode come.Decoder 110 can will decode come video flowing VS1,
VS2, VS3 are transmitted to display device 120, and are transmitted to data transmission module by audio stream AS1, AS2, the AS3 come is decoded
130。
Display device 120 is used for configuring setting according to a divided frame to use divided frame, play video flowing VS1,
The program pictures of the corresponding channel of VS2, VS3, the wherein divided frame configuration setting can by selection instruction SEL1, SEL2,
Or SEL3 is specified.
Data transmission module 130 is used for audio stream AS1, AS2, AS3 being sent in a wired or wireless manner respectively more
A mobile device 150A, 150B, 150C are dialled so that the user of multiple mobile device 150A, 150B, 150C are able to voluntarily select
Put the sub-audio stream of the channel to be watched.
Referring to Fig. 2, it is the method for handling video-audio data according to DTV disclosed in one embodiment of the invention
Flow chart, wherein module shown in FIG. 1 100 applies this method.As shown in Fig. 2, this method includes that steps are as follows：
Step 202：Multimedia data stream MS is received, multimedia data stream MS includes multiple frequencies that the DTV is provided
Encoded video flowing and audio stream in road；
Step 204：Multiple selection instruction SEL1, SEL2, SEL3 are received, each selection instruction is sent out by a mobile device
Go out, with selecting one of those channels；
Step 206：From in multimedia data stream MS, decode corresponding to those selection instructions SEL1, SEL2, SEL3 institutes
The video flowing and audio stream of those channels selected respectively；
Step 208：Respectively at multiple sprites play that those selection instructions SEL1, SEL2, SEL3 select respectively should
The video data of a little channels；And
Step 210：It is respectively transmitted those channels selected respectively corresponding to those selection instructions SEL1, SEL2, SEL3
Audio stream AS1, AS2, AS3 to send out those selection instructions SEL1, SEL2, SEL3 those mobile devices 150A, 150B,
150C。
In step 202, decoder 110 can be by receiving multimedia data stream MS in external multimedia series flow source.
In step 204, control module 140 can respectively receive selection instruction by mobile device 150A, 150B, 150C
SEL1, SEL2, SEL3, to be respectively used for selecting one of multiple channels that the DTV provided channel.
In step 206, decoder 110 can by multimedia data stream MS, respectively corresponding selection instruction SEL1, SEL2,
Channel specified by SEL3 decodes video flowing VS1, VS2, VS3 and audio stream AS1, AS2, AS3.
In a step 208, the divided frame that display device 120 can be specified by selection instruction SEL1, SEL2 or SEL3
It sets to generate multiple sprites, and plays the content of video flowing VS1, VS2, VS3 respectively in these sprites.In this hair
In a bright embodiment, selection instruction SEL1, SEL2, SEL3 are respectively used to specify the arrangement of the divided frame in display device 120
Mode includes size, relative position, permutation and combination, the picture shape etc. between divided frame.
In step 210, the source of respective corresponding selection instruction SEL1, SEL2, the SEL3 of the meeting of data transmission module 130, comes
Audio stream AS1, AS2, AS3 are transmitted to mobile device 150A, 150B, 150C so that mobile device 150A can play received
Audio stream AS1, mobile device 150B can play received audio stream AS2, mobile device 150C can play it is received
Audio stream AS3.
By method shown in Fig. 2, it may make that the user of mobile device 150A, 150B, 150C can be respectively simultaneously aobvious
Its program to be watched is watched on showing device 120, and be can pass through mobile device 150A, 150B, the 150C respectively held and come directly
Listen to the program audio that sub-audio stream AS1, AS2, AS3 are broadcast and will not be interfering with each other.
Thus, which method shown in Fig. 2 can overcome when DTV plays divided frame in prior art because only
The shortcomings that having monophonic and the program audio of the different channel specified by two or more users can not be broadcast.
It note that and method shown in Fig. 2 is imposed into rational permutation and combination and/or was once referred to plus this specification any
Restrictive condition and derivative embodiment, still should be regarded as the embodiment of the present invention.
Kei of the present invention shows a kind of method handling video-audio data and the module using this method, makes by by two or more
The audio stream of different channel specified by user is directly transferred to the mobile device that those users respectively hold so that those make
User is able to be not only capable of playing monophonic audio by DTV to be limited and be able to listen to the program audio for the channel that it to be watched
Frequently.
