Abstract: A method for obtaining content includes determining that a playout of one or more other pieces of content is dependent upon a playout of a first piece of content. The method also includes obtaining the first piece of content and identifying a forced content token associated with the first piece of content. The method further includes obtaining an access token using the forced content token. In addition, the method includes using the access token to obtain the one or more other pieces of content. The forced content token could be identified as a hash of the first piece of content or as a watermark extracted from the first piece of content. The forced content token could also be identified by creating a thumbnail for each of one or more frames in the first piece of content and calculating a differential trace signature for each of the one or more frames.

Abstract: A method includes calculating a complexity value for each segment or version of multimedia content. The multimedia content has multiple versions associated with common content and different encoding parameters, and each version is divided into segments. The method also includes adaptively streaming the multimedia content to a client device based on at least some of the calculated complexity values. The complexity value for each segment or version is calculated by summing multiple operation complexity values defining complexities of operations for decoding the segment or version. The operation complexity values could include values for a bit parsing operation, a buffer initialization operation, an intra-prediction operation, an inverse quantization and transform operation, a reference block fetch operation, a fractional interpolation operation, and in-loop deblocking operation, a sample adaptive offset correction operation, an adaptive loop filtering operation, and a de-ringing filtering operation.
