17 Claims

1. A method comprises:

during an initial time period:

in response to receiving a manifest request, for a digital video, from a first device associated with a first device address:

accessing a historical viewership rate of the digital video;

calculating a target length for a first session identifier, the target length proportional to the historical viewership rate; and

generating the first session identifier associated with the first device address, the first session identifier comprising a pseudorandom value characterized by the target length;

retrieving a generic manifest defining a set of rendition segment addresses of a set of rendition segments, within a set of renditions, available at the initial time period for the digital video;

generating a first manifest defining the set of rendition segment addresses annotated with the first session identifier; and

serving the first manifest to the first device;

during a first time period:

receiving a first content request for a first rendition segment, in the set of rendition segments, in a first rendition, in the set of renditions;

detecting the first device address in the first content request;

detecting the first session identifier in the first content request;

based on association between the first device address and the first session identifier:

extracting a first rendition segment address, for the first rendition segment, from the first content request;

retrieving the first rendition segment at the first rendition segment address; and

serving the first rendition segment to the first device address for playback; and

during a second time period:

receiving a second content request for a second rendition segment in the first rendition;

detecting a second device address in the second content request;

detecting the first session identifier in the second content request; and

based on disassociation of the second device address and the first session identifier, withholding delivery of the second rendition segment to a second device at the second device address.
