Video information periodic broadcasting method and apparatus, and video information receiving method and apparatus

A video information periodic broadcasting apparatus, comprising:

• a first segmenting unit, configured to segment video information with an equal duration to obtain video segments Si of each time series, wherein i is the segment serial number of the video segments, all the video segments Si are connected in series in an order of ascending the segment serial numbers to form the video information, and the time series is a duration of each video segment Si of a video program;
• a second segmenting unit, configured to segment each video segment Si with an equal duration to obtain video sub-segments Si,j of each time series, wherein 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, i is the segment serial number of the video segments, j is the sub-segment serial numbers of all the video sub-segments of the video segment, and all 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;
• and
• a first periodic broadcasting delivery unit, configured to transmit the video sub-segments of all the time series through at least two periodic broadcasting channels to implement video information periodic broadcasting,
• wherein the first periodic broadcasting delivery unit comprises:
• a first periodic broadcasting delivery module, configured to successively place first video sub-segments of each video segment at corresponding positions in a space of a first time series of a corresponding periodic broadcasting channel in an order of ascending the serial numbers of periodic broadcasting signals based on the sizes of the first video sub-segments of each video segment according to the order of ascending the segment serial numbers;
• and
• a second periodic broadcasting delivery module, configured to make, in a space of any other time series kin all periodic broadcasting channels, the positions of the video sub-segments Si,j of each video segment Si in the periodic broadcasting channel the same as the positions of the first video sub-segments Si,1 of the corresponding video segment in the space of the first time series of the periodic broadcasting channel;
• wherein j=(k−1) mod i+1.
