1. A method for transmitting streaming media, comprising:

  • generating at least one index segment, wherein the at least one index segment comprises index information of at least one media segment, and the at least one index segment and the at least one media segment are separate;

    generating storage location information corresponding to the at least one index segment according to a generation rule of the storage location information corresponding to the at least one index segment; and

    storing the at least one index segment at a storage location corresponding to the storage location information, so that a client obtains the at least one index segment from the storage location; and

    wherein;

    an index segment of the at least one index segment comprises index information of media segments from multiple encoding representations, wherein durations of the media segments of different encoding representations are different, wherein time boundaries of the at least one index segment and time boundaries of the at least one media segment are not aligned, wherein a particular media segment partially falls within a time range of a particular one index segment, and the particular one index segment only records index information of the particular one media segment that falls within the time range of the particular one index segment;

    oran index segment of the at least one index segment comprises index information of media segments of each encoding representation in the same time range, wherein boundaries of the index segment and the media segments are aligned;

    oran index segment of the at least one index segment only comprises index information of one media segment of one encoding representation, wherein a duration of an index segment is equal to a duration of a media segment;

    oran index segment of the at least one index segment is corresponding to an encoding representation and comprises information of multiple media segments from the encoding representation, wherein a duration of the index segment is the sum of durations of multiple media segments of the encoding representation.
