A video information periodic broadcasting method includes segmenting video information with an equal duration to obtain video segments Si of each time series, where i is the segment serial number of the video segments. The video segments Si are connected in series in an order of ascending the segment serial numbers. Segmenting each video segment Si with an equal duration to obtain video sub-segments Si,j of each time series, where the number of the video sub-segments Si,j of each time series is equal to the segment serial number of the video segments corresponding to the same time series, j is the sub-segment serial numbers of all the video sub-segments of the video segment. The video sub-segments Si,j are connected in series in an order of ascending the sub-segment serial numbers to form the video segment Si. Transmitting the video sub-segments through multiple periodic broadcasting channels with an equal bandwidth.
