    摘要: The loss of packets in a communication system can be minimized in an optimal manner by adapting a set of error correction (EC) parameters in response to a calculated probability of packet loss. The calculated probability is obtained from derived algorithms that are applied to a set of communication parameters. Algorithms are derived from Bernoulli-distributed traffic models and constant bit rate (CBR) traffic models of the communication system. A collapsed-state model is used to derive a very efficient algorithm that calculates an approximate probability of packet loss. Alternate applications for the algorithms are also disclosed.

    摘要: Techniques for re-associating dynamic metadata with media data are provided. A media processing system creates, with a first media processing stage, binding information comprising dynamic metadata and a time relationship between the dynamic metadata and media data. The binding information may be derived from the media data. While the first media processing stage delivers the media data to a second media processing stage in a first data path, the first media processing stage passes the binding information to the second media processing stage in a second data path. The media processing system re-associates, with the second media processing stage, the dynamic metadata and the media data using the binding information.

    摘要: A method for use in identifying a segment of audio and/or video information comprises obtaining a query fingerprint at each of a plurality of spaced-apart time locations in said segment, searching fingerprints in a database for a potential match for each such query fingerprint, obtaining a confidence level of a potential match to a found fingerprint in the database for each such query fingerprint, and combining the results of searching for potential matches, wherein each potential match result is weighted by respective confidence level. A confidence level may be a function of at least one or both of (1) a measure of difference between a query fingerprint and a found fingerprint and (2) the relative timing relationship between the time location of a query fingerprint and the time location of a found fingerprint.
