For some old fashioned video, generally interleaved I standard video, also interleaved I standard pattern can be used when video frequency output for old-fashioned television set, but typically require when I standard video is play by filtering to avoid the other defects such as image flicker, the horizontal resolution causing video substantially can reduce half, and then cause user when watching the I standard video of television for play, and can feel unintelligible, i.e. user cannot watch high definition or the I standard video of the super type such as clear.Therefore, the P standard video type of current video type many employings surface sweeping line by line, television set is also provided simultaneously with I standard output mode and P standard output mode, in order to plays the video of different systems type, but is typically defaulted as P standard output mode.
For combined system video, due to reasons such as some error coded, cause and the video of this type can include I system types frame of video and P standard video frame simultaneously.No matter use I standard output mode or P standard output mode when playing combined system video at television set, broadcasting all can be caused abnormal.Exemplary, a kind of common combined system video is beginning and the middle frame of video with a small amount of I system types, remaining is the frame of video of P system types, when television set uses P standard output mode to play this combined system video, Caton phenomenon is there will be when being played to I standard video frame, cause television set cannot normal play the type video, in turn result in user and cannot normally watch the video of the type by television set.
In the step s 120, when the video type of video to be played is combined system, by the target video that video conversion to be played is single system types.
Therefore, in order to avoid television set cause when playing combined system video can not normal play, such as phenomenons such as cards, TV box get will by the video to be played of television for play time, TV box can detect the video type of this video to be played, if the video type of this video to be played is combined system type video, then TV box can be by target video that this video conversion to be played is single system types.Owing to current television set can play I system types video or P system types video, it is therefore desirable to by the target video that combined system video conversion is single system types, it is simple to television set can be with this target video of normal play.
In step s 130, the video output mode controlling to preset terminal is corresponding with the system types of target video, and plays target video in default terminal.
TV box is after by video to be played by the target video that video conversion is single system types of combined system type, in addition it is also necessary to control television set video output mode is corresponding with the system types of target video.Exemplary, if the system types of target video is I system types video, the most now TV box checks the video output mode of television set, if being now I standard output mode, the most constant, if now television set is P standard output mode, then the P standard output mode of television set is adjusted to I standard output mode.
