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.

Transmitters and receivers in multiple description coding systems use correlating and decorrelating transforms to generate and process multiple descriptions of elements of an input signal. The multiple descriptions include groups of correlating transform coefficients that permit recovery of an inexact facsimile of the signal if some of the correlating transform coefficients are lost or corrupted during transmission. Noiseless implementations of the correlating and decorrelating transforms are described that allow the signal elements to be quantized with different quantizing resolutions. Implementations using the Fast Hadamard Transform are described that reduce the resources needed to perform the transforms.

Blocks of audio information are arranged in groups that share encoding control parameters to reduce the amount of side information needed to convey the control parameters in an encoded signal. The configuration of groups that reduces the distortion of the encoded audio information may be determined by any of several techniques that search for an optimal or near optimal solution. The techniques include an exhaustive search, a fast optimal search and a greed merge, which allow the search technique to tradeoff the reduction in distortion against the bit rate of the encoded signal and/or the computational complexity of the search technique.

Signatures that can be used to identify video and audio content are generated from the content by generating measures of dissimilarity between features of corresponding groups of pixels in frames of video content and by generating low-resolution time-frequency representations of audio segments. The signatures are generated by applying a hash function to intermediate values derived from the measures of dissimilarity and to the low-resolution time-frequency representations. The generated signatures may be used in a variety of applications such as restoring synchronization between video and audio content streams and identifying copies of original video and audio content. The generated signatures can provide reliable identifications despite intentional and unintentional modifications to the content.

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.

A signature that can be used to identify video content in a series of video frames is generated by first calculating the average and variance of picture elements in a low-resolution composite image that represents a temporal and spatial composite of the video content in the series of frames. The signature is generated by applying a hash function to values derived from the average and variance composite representations. The video content of a signal can be represented by a set of signatures that are generated for multiple series of frames within the signal. A set of signatures can provide reliable identifications despite intentional and unintentional modifications to the content.

A media fingerprint is derived from a portion of media content. Information is associated with the media content portion based on the derived media fingerprint. Upon linking to the associated information, the associated content is presented with the media content portion. The media fingerprint includes a unique representation of the media content portion that is derived from a characteristic component of the media content portion. The media content may comprise an original instance of content or a derivative instance of the original content.

Methods, apparatuses and program logic in storage media to process media data for quality enhancement. Information is accepted from a resource constrained device, e.g., a wireless portable device related to the quality enhancement and/or environmental quantities such as background noise and/or ambient lighting for the device. Media data is data processed to achieve quality enhancement using at least some of the accepted information to generate processed output. The data processing of the media data includes processing when or where one or more resources sufficient for the processing are available.
