摘要： 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.

摘要： Techniques are provided for dynamic configuration of search parameters for multimedia fingerprint databases that use weak bits. A multimedia fingerprint database, which stores reference fingerprints and uses weak bits, is maintained. Maintaining the database includes dynamically configuring one or more of the following parameters: a fingerprint length of those portions of the reference fingerprints that are used to identify multimedia objects; an index length of the index used to index those portions of the reference fingerprints that are used to identify multimedia objects; a threshold that is used to determine whether multimedia objects are correctly identified; and a number of the weak bits in the reference fingerprints.

摘要： Multiple candidate feature components of media content or projection matrices (or other hash functions, e.g., non-linear projections) are identified. Each of the candidate projection matrices (or other hash functions) includes an array of coefficients that relate to the candidate features. A subgroup of the candidate features or the projection matrices (or other hash functions) are selected based at least partially on an optimized combination of at least two characteristics of the candidate features or projection matrices (or other hash functions). Media fingerprints that uniquely identify the media content are derived from the selected optimized subgroup. Optimal projection matrices (or other hash functions) may be designed. Performance or sensitivity (e.g., search time) characteristics of the fingerprints are thus balanced with robustness characteristics thereof.
摘要翻译：识别媒体内容或投影矩阵（或其他散列函数，例如非线性投影）的多个候选特征分量。每个候选投影矩阵（或其他散列函数）包括与候选特征相关的系数阵列。至少部分地基于候选特征或投影矩阵（或其他散列函数）的至少两个特征的优化组合来选择候选特征或投影矩阵（或其他散列函数）的子组。唯一标识媒体内容的媒体指纹是从选定的优化子组派生出来的。可以设计最佳投影矩阵（或其他散列函数）。因此，指纹的性能或灵敏度（例如，搜索时间）特性与其鲁棒性特性相平衡。

摘要： A portion of media content is accessed. Components from a first and each subsequent spatial regions of the media content are sampled. Each spatial region has an unsegmented area. Each subsequent spatial region includes those within its area as elements thereof or the spatial regions may partially overlap. The regions may overlap independent of a hierarchical relationship between the regions. A media fingerprint is derived from the components of each of the spatial regions, which reliably corresponds to the media content portion, e.g., over geometric attacks such as rotation.

摘要： Methods, apparatuses and program logic in storage media to process media data for quality enhancement. The media data is for rendering at a wireless device. Environmental quantities are accepted from one or more sensors located remote from the wireless device but sufficiently close to be indicative of similar quantities in the device's environment. The sensors at in or connected to a network node. At the network node, the method includes processing the media data using the environmental quantities to generate processed data, and wirelessly sending the processed output to the resource constrained device for rendering, such that the processed output is usable by the resource constrained device to render or to process and render the media data.
