Embodiment
Refer to Fig. 1, its module 100 for the process video-audio data disclosed according to one embodiment of the invention transmits the voice data that exists with sub-audio flow pattern state to the function block schematic diagram of multiple mobile device 150A, 150B, 150C.Module 100 is applied to a Digital Television, and this Digital Television can be used to show multiple sprite simultaneously.
Module 100 comprises decoder 110, display unit 120, data transmission module 130, control module 140 and a detection module 180.
Detection module 180 is used for supplementary module 100 and detects for the mobile device in this Digital Television one detection range, multiple mobile device 150A, 150B, 150C detected, and be used for setting up control module 140 and multiple network connectivity between mobile device 150A, 150B, 150C and data transmission module 130 and multiple network connectivity between mobile device 150A, 150B, 150C, wherein this network connectivity can be wired or wireless.
Control module 140, be used in a wired fashion or wireless mode receive selection instruction SEL1, SEL2, SEL3 separately by multiple mobile device 150A, 150B, 150C, and each selection instruction corresponding produces one first control signal and one second control signal separately, wherein this first control signal can be transferred to decoder 110 by control module 140, the mode of decoding is carried out to indicate decoder 110, and this second control signal can be transferred to data transmission module 130 by control module 140, carry out the mode of transfer of data with designation data transport module 130.Selection instruction SEL1, SEL2, SEL3 are used for one of them channels of the multiple channels selecting this Digital Television to provide separately.With Fig. 1 for example, control module 140 corresponding selection instruction SEL1 generation one first control signal C11 and one second control signal C12, corresponding selection instruction SEL2 can produce one first control signal C21 and one second control signal C22, and corresponding selection instruction SEL3 produces one first control signal C31 and one second control signal C32.In one embodiment of this invention, control module 140 can set in the configuration in addition specified by selection instruction SEL1, SEL2 or SEL3, and change display unit 120 shows configuration mode during each divided frame.
The channel of decoder 110 meeting indicated by this first control signal, by module 100 by the video flowing decoded in a multimedia data stream MS of external reception corresponding to this channel and audio stream.With Fig. 1, the video flowing VS1 that one first channel indicated by the first control signal C11 is corresponding in multimedia data stream MS can decode out with an audio stream AS1, decodes out by a video flowing VS2 corresponding in multimedia data stream MS for one second channel indicated by the first control signal C12 with an audio stream AS2, decodes out by a video flowing VS3 corresponding in multimedia data stream MS for 1 indicated by the first control signal C13 a 3rd channel and audio stream AS3 by decoder 110.Decoding video flowing VS1, VS2, VS3 out can be transferred to display unit 120 by decoder 110, and decoding audio stream AS1, AS2, AS3 are out transferred to data transmission module 130.
Display unit 120 is used for using divided frame according to a divided frame configuration setting, the program pictures of each self-corresponding channel of displaying video stream VS1, VS2, VS3, wherein this divided frame configuration setting can be specified by selection instruction SEL1, SEL2 or SEL3.
Data transmission module 130 is used for audio stream AS1, AS2, AS3 to be sent to multiple mobile device 150A, 150B, 150C respectively in a wired or wireless manner, is selected to make the user of multiple mobile device 150A, 150B, 150C the sub-audio stream dialling the channel put for viewing voluntarily.
Refer to Fig. 2, its for according to one embodiment of the invention disclose the flow chart of the method for Digital Television process video-audio data, namely the module 100 wherein shown in Fig. 1 applies the method.As shown in Figure 2, to comprise step as follows for the method:
Step 202: receiving multimedia data stream MS, multimedia data stream MS comprise encoded video flowing and audio stream in multiple channels that this Digital Television provides;
Step 204: receive multiple selection instruction SEL1, SEL2, SEL3, each selection instruction sent by a mobile device, with in order to select one of them of those channels;
Step 206: in multimedia data stream MS, decodes video flowing and the audio stream of those channels selected respectively corresponding to those selection instruction SEL1, SEL2, SEL3;
Step 208: play those selection instruction SEL1 respectively at multiple sprite, the video data of those channels that SEL2, SEL3 select respectively; And
Step 210: transmit audio stream AS1, AS2, AS3 of those channels selected respectively corresponding to those selection instruction SEL1, SEL2, SEL3 respectively to those mobile devices 150A, 150B, 150C of sending those selection instruction SEL1, SEL2, SEL3.
In step 202., decoder 110 can by receiving multimedia data stream MS in the multimedia series flow source of outside.
In step 204, control module 140 can receive selection instruction SEL1, SEL2, SEL3 by mobile device 150A, 150B, 150C separately, to be used for one of them channels of the multiple channels selecting this Digital Television to provide separately.
In step 206, decoder 110 can by multimedia data stream MS, and the channel respectively specified by corresponding selection instruction SEL1, SEL2, SEL3 decodes video flowing VS1, VS2, VS3 and audio stream AS1, AS2, AS3.
In a step 208, the divided frame setting that display unit 120 is understood specified by selection instruction SEL1, SEL2 or SEL3 produce multiple sprite, and distinguishes the content of displaying video stream VS1, VS2, VS3 in these sprites.In one embodiment of this invention, selection instruction SEL1, SEL2, SEL3 divided frame arrangement mode be used to specify separately in display unit 120 comprises the size, relative position, permutation and combination, picture shape etc. between divided frame.
In step 210, the source of data transmission module 130 meeting respective corresponding selection instruction SEL1, SEL2, SEL3, come transmission of audio stream AS1, AS2, AS3 to mobile device 150A, 150B, 150C, such that mobile device 150A can play received audio stream AS1, mobile device 150B can play received audio stream AS2, mobile device 150C can play received audio stream AS3.
Mat method as shown in Figure 2, the user of mobile device 150A, 150B, 150C can be made in display unit 120 simultaneously can to watch its program for viewing separately, and can pass through mobile device 150A, 150B, 150C of holding separately and directly listen to program audio that sub-audio stream AS1, AS2, AS3 broadcast and unlikely interfering with each other.
Thus, the method shown in Fig. 2 can overcome the shortcoming of the program audio of the different channel specified by user cannot broadcasting more than two when Digital Television in prior art plays divided frame because of only having monophony.
Note that and the method shown in Fig. 2 imposed rational permutation and combination and/or add any restrictive condition that this specification was once mentioned and derivative embodiment, must embodiments of the invention be considered as.
Kei of the present invention show a kind of process video-audio data method and the module of application the method, by the mobile device audio stream of the different channel specified by more than two users directly being transferred to those users and hold separately, those users are made to be able to only can not play the restriction of monophonic audio by Digital Television and be listened to its program audio for the channel of viewing.
