To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
A kind of display methods of video pictures is the embodiment of the invention provides, referring to Fig. 1, the method includes：
Step 101：When detect the first live signal source is switched to the switching command in the second live signal source when, judge
Whether the local live video stream for being cached with the second live signal source, the first live signal source is currently displaying video pictures institute
The live signal source of category.
It should be noted that the first live signal source and the second live signal source can be network direct broadcasting signal source, when
Can also be so traditional tv live signal source, such as by DVBC (Digital Video Broadcasting, digital video
Broadcast) interface, DTMB (Digital Television Multimedia Broadcasting, digital TV ground multimedia
Broadcast) interface, ATV (Analog Television, simulated television) interface, HDMI (High Definition Multimedia
Interface, HDMI) and VGA (Video GraphicsArray, Video Graphics Array) interface etc. connect
The live signal source for entering.
User can be switched over, so as to watch during live video is watched by terminal-pair live signal source
Different live videos, when terminal is detected, and current live signal source is switched into another live signal source, can play
While the live video stream in another live signal source, the live video stream to current live signal source carries out backstage caching, than
Such as traditional tv live signal source, background decoding can be carried out to video flowing by Video Decoder and cached, for net
Network live signal source, can carry out backstage and download and cache to video flowing, in this way, can cache the live letter before switching in terminal
The video flowing in number source.
In addition, the first live signal source is probably that from the second live signal source, switching comes before, it is also possible to be
Terminal one is started shooting and begins to what is played, or come from other live signal sources switching in addition to the second live signal source,
And for the first situation, after being switched to the first live signal source from the second live signal source, second can be cached with terminal
The video flowing in live signal source, and for second situation, the video flowing not cached then in terminal or can be cached with except
The video flowing in other live signal sources outside two live signal sources, therefore, when terminal detect by the first live signal source
When being switched to the switching command in the second live signal source, it is necessary first to which whether judgement is locally cached with the straight of the second live signal source
Broadcast video flowing.
Further, the first live signal source is switched to after the switching command in the second live signal source when detecting,
Terminal can be cached by following manner to the live video stream in the first live signal source, including：It is straight when receiving first
When broadcasting the live video stream of signal source, the live video stream in the first live signal source is cached, and determine the first live signal source
The beginning cache-time of live video stream；When caching the first live signal source live video stream shared by spatial cache be more than
During predetermined threshold value, cache-time in the live video stream in the first live signal source for caching is located at second and is specified in the time period
Live video stream deletion, second specifies the time period for after beginning cache-time and apart from the beginning preset duration of cache-time second
Time period.
Terminal can be cached to the live video stream in the first live signal source, so as to work as switch back into the first live signal
During source, can be obtained from the live video stream in the first live signal source of caching and show an at least frame video pictures, be used for
Played a transition role during live signal source switches, and then make to be taken over seamlessly between two live signal sources.Further, since
After user is switched over by terminal-pair current live signal source, may not switch back again, or some time
Can just switch back afterwards, and due to the limited storage space of terminal, therefore after switching live signal source, by the first signal source
Live video stream all caching then can the sizable memory space of occupied terminal, therefore, terminal can be in the first straight of caching
When broadcasting spatial cache shared by the live video stream of signal source and being more than predetermined threshold value, such as more than 40MB (MByte, Mbytes)
When, cache-time in the live video stream in the first live signal source for caching is located at the live video in the second specified time period
Stream is deleted, and that is to say that edge contract side caches, such that it is able to greatly save the memory space of terminal.
Step 102：When local cache has the live video stream in the second live signal source, from the straight of the second live signal source
Broadcast to obtain cache-time in video flowing and be located at first and specify at least frame video pictures in the time period, first specifies the time period to be
Before current time and apart from the time period of the preset duration of current time first.
Wherein, terminal obtains cache-time from the live video stream in the second live signal source and specifies the time period positioned at first
An interior at least frame video pictures can include：Cache-time is obtained from the live video stream in the second live signal source and is located at the
One specifies in the time period and a frame video pictures nearest with current time, or, from the live video in the second live signal source
The multi-frame video picture that cache-time was located in the first specified time period is obtained in stream.That is to say that terminal can only obtain caching
Last frame video pictures, it is also possible to obtain last a few frame video pictures of caching.
It should be noted that because at least frame video pictures for obtaining are used to show during live signal source switches
Show, therefore in order that the transition of video pictures is more natural, it is shorter that the first preset duration should be set, and that is to say that terminal is obtained
The quantity of video pictures should not be too many, in order to avoid the second live signal source has been accessed, and the video pictures for obtaining have not yet been displayed
Finish, so as to the problem for causing the transition of video pictures not smooth with display effect difference.
In addition, terminal can carry out shot operation so as to obtain an at least frame video pictures by the video flowing for caching,
And due to intercept a frame video pictures time quickly, typically smaller than 150ms (millisecond), thus terminal obtain an at least frame video
Picture can't be expended for a long time, so as to also not interfere with the fluency that video pictures show.
In a kind of possible implementation, when it is local it is uncached have the live video stream in the second live signal source when, eventually
End can obtain video promotion message, and video promotion message is shown in the handoff procedure in live signal source, in successful switch
During to the second live signal source, cancel the display of video promotion message, and to the live video stream correspondence in the second live signal source
Video pictures shown.
It should be noted that the video promotion message can be terminal play the first live signal source video flowing when,
The one section of video intercepted from the video flowing in the first live signal source, such as advertisement etc., certainly, the video promotion message can also
It is the video that third party provides, in addition, the public service ads video that can also be previously stored for terminal of the video promotion message etc..
In addition, when it is local it is uncached have the live video stream in the second live signal source when, terminal can show that video is promoted
Information, certainly, in actual applications, terminal can also show the picture being previously stored, or the video pictures that display is stored, and show
Example, when the video pictures can be switching live signal source recent apart from current time, to the video played
Stream carries out sectional drawing and obtains.
Step 103：An at least frame video pictures are shown in the handoff procedure in live signal source, in successful switch to second
During live signal source, cancel the display of an at least frame video pictures, and to the live video stream correspondence in the second live signal source
Video pictures shown.
Wherein, cache-time is obtained from the live video stream in the second live signal source in terminal and specifies the time positioned at first
In section and on the basis of a frame video pictures nearest with current time, terminal can show in the handoff procedure in live signal source
Show a nearest frame video pictures of acquisition, when successful switch is to the second live signal source, cancel the nearest frame for obtaining
The display of video pictures, and corresponding video pictures of live video stream to the second live signal source show.
Cache-time is obtained from the live video stream in the second live signal source in terminal to be specified in the time period positioned at first
Multi-frame video picture on the basis of, terminal can be in the handoff procedure in live signal source, according to the multi-frame video picture
Cache-time, shows the multi-frame video picture successively, when successful switch is to the second live signal source, cancels multi-frame video picture
The display in face, and corresponding video pictures of live video stream to the second live signal source show.
In embodiments of the present invention, the switching that the first live signal source is switched to the second live signal source is referred to when detecting
