The specific time for carrying out images match to determine.
Embodiment
Between the different program sources of confirmation of the present embodiment in the method for time migration, TV and mobile terminal pass through WIFI
(Wireless Fidelity, wireless network) connects.
Step 1, after mobile terminal is connected with TV by WIFI, the program on TV can be converged, for
Family browses, and multiple program sources of each program can be presented in the lump when converging program, so that user selects from multiple program sources
Program source plays the desired program of user.
Step 2, because program is encoded to program stream by each program source, after each program stream of acquisition for mobile terminal, carry out
Decoding, sampled in the setting time fragment of the program stream of each program source and obtain the multiple isochronous surfaces of sample length identical.
After obtaining isochronous surface, the isolated audio volume control of audio frequency and video and video image are carried out to all isochronous surfaces.Wherein, it is each
Program can be encoded to program stream by program source using identical coded system, then mobile terminal need to only use a kind of decoding side
Formula is all program streams of decodable code.Certainly, program can be encoded to program by different program sources using different coded systems
Stream, mobile terminal can also use different decoding process difference decoded program streams.In the present embodiment, in setting time fragment
Isochronous surface quantity of sampling quantity be 10, and the sample length of each isochronous surface be 2 seconds, the setting time of each program stream
The equal length of fragment, and the start time of setting time fragment is the start time of program stream.Preferably, setting time fragment
Length be 3 minutes.
Step 3, mobile terminal by with reference to program stream each isochronous surface audio volume control according to sampling order respectively with
The audio volume control of each isochronous surface of other program streams carries out similarity mode.When sampling to obtain 10 due to each program stream
Between cut into slices, then with reference to 10 isochronous surfaces of program stream, according to sampling order, 10 times of other program streams cut respectively successively
Piece carries out the similarity mode of audio volume control.If 10 times match obtained similarity and reach predetermined threshold, audio is considered as
The match is successful.Similarity is related to the waveform of audio volume control, if waveform is closer, even if the amplitude of waveform differs, also recognizes
It is higher for similarity.Here similarity can be quantified.Pass through the similarity mode of audio volume control, it may be determined that with reference to section
Mesh stream and the approximate time section of other program stream time synchronizeds.
Step 4, Audio Matching success after, mobile terminal by with reference to program stream each isochronous surface video image according to
Sampling order carries out images match with the video image of each isochronous surface of other program streams respectively.Because each program stream takes
Sample obtains 10 isochronous surfaces, then distinguishes other program streams successively according to sampling order with reference to 10 isochronous surfaces of program stream
10 isochronous surfaces carry out video image images match.The algorithm of images match can use classical efficient sift to calculate
Method, sciagraphy, characteristic method etc..After images match success, it is possible to specific time point is determined in approximate time section.
Step 5, images match success, the start time of the setting time fragment of the other program streams of mobile terminal records are relative
In the offset of the start time of the setting time fragment with reference to program stream.The offset i.e. program stream of setting time fragment
Offset.For example, synchronous time point was only with the 4th minute of some program stream A with reference to the 1st minute of program stream,
So program stream A is 3 minutes relative to the offset with reference to program stream.The 2nd minute of reference program stream is with some program stream B's
It is only synchronous time point within 1st minute, then program stream B is -1 minute relative to the offset with reference to program stream.Assuming that user
It is switched to program stream A within the 10th minute in program stream B, then program stream B is -5 minutes relative to program stream A offset, then
It will start to broadcast within program stream A to the 15th minutes according to program stream B down times (the 10th minute) and offset -5 minutes, adjustment
Put, so that user, which switches when program source plays program, realizes break-point continuous playing.
Step 6, if the similarity that the matching of audio volume control obtains at least once is not reaching to predetermined threshold, by other
The start time of the setting time fragment of the program stream of program source is moved rearwards scheduled duration, and re-starts step 2 to step
3.It is 3 minutes that the present embodiment, which sets scheduled duration, then constant with reference to the start time of the setting time fragment of program stream, Qi Tajie
The start time of the setting time fragment of mesh stream is moved rearwards three minutes, that is to say, that the setting time fragment of other program streams
Time span it is constant, but start time change.
