1. a method that presents stored multimedia programming, described multimedia programming is not yet indexed before its storage, select be discontinuous presentation modes time, described method comprises:

  • Receive and find input;

    Statistical information based on relevant to described multimedia programming, the data of determining a part for the to be loaded multimedia programming of storing read size, wherein, described in, read size and be the twice of the average group of picture GOP size that described statistical information comprises but be less than maximum read buffers size;

    By seek vector, determine and find position, describedly find the product that vector equals average frame size that the number of frames of skipping and described statistical information are comprised, the searching vector calculating is added to current file pointer position and adjusts result according to half of described average group of picture GOP size;

    From the starting position based on described searching input by thering is a determined part that reads the multimedia programming of storing of size, be loaded into read buffers;

    Analyze institute'"'"'s loading section of described program, to determine whether to exist complete data I frame;

    If navigate to complete I frame, forward institute'"'"'s loading section of described program for demonstration.
