Referring to Fig. 1, a kind of main method flow process of video switch is as follows in the embodiment of the invention:
Step 101: in the process of playing current video, determine the channel at current video place.
The method of determining the channel at current video place has multiple, below introduces several:
First method: each video is the video of corresponding channel, and each channel has the channel station symbol, and particularly, first method can comprise steps A 1-A3:
Steps A 1, in playing the process of current video, the playing image of intercepting current video obtains a video interception;
Steps A 2, the channel station symbol in the above-mentioned video interception is analyzed;
Steps A 3, determine the channel at current video place according to the result of above-mentioned analysis.
Image processing at present and mode identification technology are ripe, and the method for the channel at the definite current video of this kind place can be determined the channel at current video place more accurately.
Second method: because the programm name of displaying video is arranged in the information on services SI (service information) of TS (transport stream) stream with the add list form, so can determine programm name by the text message of add list in the Analysis Service information, thereby determine the channel at current video place.Concrete, second method can comprise step B1-B2:
Step B1, obtain the information on services of current video transport stream;
Step B2, determine the channel at current video place according to above-mentioned information on services.
The method of the channel at the definite current video of this kind place is fairly simple, the efficient height.
Step 102: when current video is play end, pick up counting.
Before step 102, also comprise step: judge whether current video plays end.
Can judge whether current video plays end by several different methods:
Judge whether current video plays the method for end for first kind: when getting access to current video broadcast end notification, determine that the current video broadcast finishes.
Judge whether current video plays the method for end for second kind: when the current time is current video broadcast concluding time point, determine that the current video broadcast finishes.Wherein, the current time can be local zone time, and current video is play the concluding time point and can be determined by frame and time difference and the current time of end frame on time shaft that current video is play.For example, current time is local zone time, the frame that current video is play and the end frame time difference on time shaft is 1 hour, local zone time is points in the mornings 9 on January 1st, 2013, then to play the concluding time point be points in the mornings 10 on January 1st, 2013 to current video, when local zone time was at 10 in the morning on January 1st, 2013, current video was play and is finished.
When the above-mentioned current time is local zone time, because may there be clocking error in local zone time, so before the channel step of determining the current video place, need also that to carry out clock synchronous with server end, can carry out a simultaneous operation, perhaps periodically carry out simultaneous operation.Judge whether current video is play end and be may further comprise the steps C1-C3 this moment:
Step C1, to carry out clock synchronous with the transmitting terminal server;
Step C2, obtain current video and play the concluding time point;
Step C3, when local zone time is that current video is play the concluding time during point, determining that current video is play finishes.
When being current video broadcast concluding time point, local zone time determines that the current video broadcast finishes, do not need to carry out repeatedly transfer of data with the transmitting terminal server, can avoid problems such as network delay, determine that the time point of video playback end is accurate, the program synchronous effect is good.
Step 102 can realize clocking capability by timer.The timing duration of default timer when the timer timing finishes, can produce interrupt signal.
Step 103: when timing accumulative total duration reaches default duration, broadcast interface is switched to the live TV stream interface of described channel.
Wherein, the span of default duration can be 0～60 second, such as above-mentioned default duration can be 0 second, and 5 seconds, 10 seconds, 30 seconds equivalences can also be other numerical value of also growing than 60 seconds certainly.
Above-mentioned default duration can be default, also can the user independently set, and it is 0 that supposing the system is set default duration, then carries out the video switch operation after current video is play end immediately.If default duration is 10 seconds, then timer picks up counting when current video is play end, stops timing in the time of 10 seconds in timing, produces interrupt signal simultaneously, then broadcast interface is switched to the live TV stream interface of described channel correspondence.
In the time broadcast interface need being switched to the live TV stream interface corresponding with above-mentioned channel, obtain the live code stream of audio frequency and video of above-mentioned channel, by decoder the live code stream of above-mentioned audio frequency and video is decoded, produce the audio-video signal of live TV stream, and then play above-mentioned live TV stream.
The video switching method that the embodiment of the invention provides goes for interactive digital TV or Web TV, program in user's program request EPG, after the program of program request is play end, adopt above-mentioned video switching method broadcast interface initiatively to be switched in the live TV stream interface of above-mentioned channel, can solve existing video playback and finish the problem that the no program in back is followed broadcast automatically, can realize the automatic follow-up play of program.
Below by specific embodiment, respectively explanation adopt different settled really before the method for video place channel when judging whether current video plays the method for end, realize the process of video switch with different.

Step 202: the channel station symbol in the above-mentioned video interception is analyzed.
Step 203: the channel of determining the current video place according to the result who analyzes.
For example user's program request EPG watches a certain film of movie channel, then has the station symbol of movie channel on the upper left side of displaying video, and no matter plays what film, and the channel station symbol is always on the upper strata of mute and can not change.Can intercept the video interception of current video this moment, upper left station symbol zone in the video interception of obtaining is compared with the station symbol database, thereby the station symbol that can analyze in the video interception identifies, and then definite current video is the video in the movie channel.
Step 204: when getting access to the broadcast end notification of current video, pick up counting.
Step 205: when the accumulative total duration reaches default duration, broadcast interface is switched to the live TV stream interface of above-mentioned channel.
Video playback has certain notice when finishing, such as an interruption pulse or the video playback end signal that initiatively sends or the end frame in the video.When getting access to the broadcast end notification of current video, timer picks up counting, and default duration is that video playback finishes to the time span between the video switch.Be 10 seconds such as default duration, begin countdown when then video playback finishes, the timer timing produced interrupt signal after 10 seconds, and the video switch operation is carried out in indication.

Step 303: the channel of determining the current video place according to above-mentioned information on services.
Step 304: judge whether local zone time is that current video is play the concluding time point, if then continue step 306, otherwise continue step 305.
Step 305: continue to wait for when local zone time reaches current video broadcast concluding time point, continue step 306.
Step 306: when local zone time is current video broadcast concluding time point, pick up counting.
Step 307: when the accumulative total duration reaches default duration, broadcast interface is switched to the live TV stream interface of above-mentioned channel.
Suppose that default duration is 10 seconds, still with the example explanation in step 302 explanation, it is points in the mornings 11 on January 1st, 2013 that current video is play the concluding time point, if the current time is not also to point in the mornings 11 on January 1st, 2013, video broadcast end as yet is described, only when local zone time is at 11 in the morning on January 1st, 2013, illustrate that just video playback finishes, this moment, timer picked up counting, when timer timing in the time of 10 seconds, the accumulative total duration reaches default duration 10 seconds, then broadcast interface is switched in 0 minute 10 seconds the live TV stream interface of above-mentioned channel at 11 o'clock in the morning on January 1st, 2013.
At first carry out clock with the transmitting terminal server and can reduce clocking error synchronously; Be that current video is play the concluding time point as the condition of video switch with the local zone time, the time is accurate, and the program synchronous effect is good, and does not need to carry out repeatedly transfer of data with the transmitting terminal server, can avoid problems such as network delay.Information on services according to current video is determined the channel corresponding with current video, does not need lengthy and jumbled data to handle, and can not take too much system resource, and method is simple, the efficient height.When local zone time is after current video is play the concluding time point, broadcast interface is switched to the live TV stream interface of current channel, solve existing video playback and finish the problem that the no program in back is followed broadcast automatically, can realize the automatic follow-up play of program.Embodiment one and embodiment two are the concrete introduction to video switching method, be not these two kinds of situations but do not limit, also can judge whether current video plays the method for end in conjunction with the method for above-mentioned first kind of definite current video place channel and above-mentioned second kind, perhaps adopt other methods of determining current video place channel and judge whether current video plays the method for end.
