Media processing devices for adaptive delivery of on-demand media, and methods thereof

摘要

In one embodiment, a method of streaming media includes partitioning a media stream to be transmitted into a first stream of media segments at a media server. The first stream of the media segments has a first sequence. An index table is generated to identify the first sequence of the first stream of the media segments. The index table is encrypted using a key. A second stream of the media segments is generated. The second stream has a second sequence, which is random relative to the first sequence. The encrypted index table and a transcoded media stream having the second stream of the media segments are transmitted.

1. A method of streaming media, the method comprising:
at a media server, partitioning a media stream into a first stream of media segments; transcoding individual media segments in the first stream of media segments to obtain a first stream of transcoded media segments, the first stream of transcoded media segments having a first sequence; generating an index table identifying the first sequence; encrypting the index table using a key; randomizing the first stream of transcoded media segments by placing transcoded media segments of the first stream of transcoded media segments in a random order to obtain a second stream of transcoded media segments, the second stream of transcoded media segments having a second sequence, the second sequence being random relative to the first sequence; and transmitting the encrypted index table and the second stream of transcoded media segments.
