摘要： Fingerprint-based content identification is described. Bin-counting detects linear trends based on data points that are generated from a set of query fingerprints, which are extracted from a query content item and a matching set of corresponding reference content items that are extracted from a reference content item. RANSAC may detect trends based on confidence scores that are computed for multiple candidate content items. The trends detected for the candidate content items are compared against a threshold in order of decreasing confidence score until a trend that satisfies the threshold is found. A ranking-based mechanism for fingerprint-based content identification may use a bin-counting or RANSAC-based trend detection mechanism to identify duplicate or multiple reference content items that all match the same query content item.
摘要翻译：描述基于指纹的内容识别。二进位计数基于从查询内容项提取的一组查询指纹和从参考内容项提取的对应参考内容项的匹配集合生成的数据点来检测线性趋势。 RANSAC可以基于针对多个候选内容项目计算的置信度分数来检测趋势。将候选内容项目检测到的趋势与阈值进行比较，以降低可信度得分，直到找到满足阈值的趋势为止。用于基于指纹的内容识别的基于排名的机制可以使用二进位计数或基于RANSAC的趋势检测机制来识别所有匹配相同查询内容项的重复或多个参考内容项。

摘要： Information is associated with media content. Upon an upload of a portion of the media content, a media fingerprint is derived therefrom. The media fingerprint includes a unique representation of the media content portion, which is derived from a characteristic component of the media content portion. The information is associated with the media content portion based on the derived media fingerprint. Upon streaming the media content portion, the associated information is linked and presented in real time with the media content portion. Upon upload of the media content portion, the media fingerprint may be derived therefrom at upload time or at any time subsequent to upload time and prior to presentation time. The media content may comprise an original instance of content or a derivative instance of the original content.

摘要： A target hash value is identified. Identifying a target hash values includes computing a query hash value, partitioning the query hash value into at least a first portion and a second portion, and locally assigning weak bits within the first portion of the query hash value and weak bits within the second portion of the query hash value. The method further includes determining one or more variations of the query hash value with toggling one or more weak bits in the first portion and one or more weak bits in the second portion of the query hash value; and identifying a target hash value that is identical to a variation of the query hash value.

摘要： Media fingerprints, which are each derived from and uniquely correspond to a portion of media content, are stored over a distributed database. An instance of one or more information containers of the distributed database are each disposed over two or more computing devices, which are communicatively linked over a data network. The media fingerprints are distributed among the information containers based on a criterion that relates individually to each of the media fingerprints. Upon a query directed to one of the media fingerprints, at least one of the two or more computing devices is selected based on the criterion. The query is executed over the distributed database instance of the selected computing device.

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： Processors that encrypt frames of data representing images and sounds, for example, use a first encryption process to encrypt control data that includes selected data from the data frames and use a second encryption process to encrypt non-selected data from the data frames. The first encryption process is responsive to a key, which may be associated with an intended recipient of the data frames. The second encryption process is responsive to a key that is obtained or derived from the control data. The encrypted control data and the encrypted non-selected data may be delivered to a receiver using separate media. The receiver recovers the data frames using decryption processes that are inverse to the first and second encryption processes. Efficient implementations of the second encryption process are disclosed.

摘要： A receiver monitoring the transmissions of a packet processing device such as a wireless access point analyzes the monitored transmissions to estimate the probability of packet loss due to buffer overflow in the processing device. The loss probability can be estimated for individual packets to follow rapid changes in communication conditions. An indication of the estimated loss probability can be used to adapt the forward error correction (FEC) parameters that are used to generate the packets, thereby improving the reliability of data delivery to a receiver while optimizing the use of communication channel bandwidth.
