Abstract: Embodiments of identifying multimedia objects based on multimedia fingerprints are provided. Query fingerprints are derived from a multimedia object according to differing fingerprint algorithms. For each fingerprint algorithm, decisions are calculated through at least one classifier corresponding to the fingerprint algorithm based on the query fingerprint and reference fingerprints, the reference fingerprints being derived from reference multimedia objects according to the same fingerprint algorithm. Each of the decisions indicates a possibility that the query fingerprint and the reference fingerprint are not derived from the same multimedia content. For each of the reference multimedia objects, a distance is calculated as a weighted sum of the decisions relating to the reference fingerprints. The multimedia object is identified as matching the reference multimedia object with the smallest distance less than a threshold.

Abstract: Methods, apparatuses and program logic in non-transitory media to process video 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 ambient lighting for the device. The video data is processed to achieve quality enhancement using at least some of the accepted information to generate processed output. The processing of the video data includes processing when or where one or more resources sufficient for the processing are available.

Abstract: 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.
Abstract translation: 提供了将动态元数据与媒体数据重新关联的技术。 媒体处理系统在第一媒体处理阶段创建包含动态元数据和动态元数据与媒体数据之间的时间关系的绑定信息。 可以从媒体数据导出绑定信息。 当第一媒体处理阶段将媒体数据传送到第一数据路径中的第二媒体处理阶段时，第一媒体处理阶段将绑定信息传递到第二数据路径中的第二媒体处理阶段。 媒体处理系统使用绑定信息在第二媒体处理阶段重新关联动态元数据和媒体数据。
