    Abstract: A server device includes memory to store a database of frame fingerprints ordered sequentially by media item number and frame number for media items and a hash table containing (key, value) entries each including a hashed frame fingerprint and index number(s) to the database. A processor, for an input set of hashed frame fingerprints, selects a most recent hashed frame fingerprint. The processor performs a lookup with the most recent hashed frame fingerprint to identify a plurality of index numbers from a matching entry. The processor retrieves a target plurality of frame fingerprints from the database using each of the plurality of index numbers as a starting point; calculates a rank distance between the input set and each respective target plurality of frame fingerprints; and selects the target plurality of frame fingerprints for which the rank distance is shortest, to identify a media item.

    Abstract: An adaptive watermarking service receives a request including a device identifier and a requested address associated with a first segment of content. The requested address may be identified in a published manifest describing multiple segments for a content item, where each segment is encoded at multiple different bitrates. The adaptive watermarking service identifies multiple storage locations of the first segment in view of the requested address. The multiple storage locations each have a version of the first segment with a watermark value. The adaptive watermarking service selects a return version from the versions associated with the first segment in view of a watermarking rule, where the return version has a watermark value satisfying the watermarking rule. The adaptive watermarking service sends a message with the device identifier and a return storage location that identifies the selected return version.

    Abstract: A biststream of encoded video data captured by a camera (4) of a user device (1, 2, 3) is received and decoded into a stream of decoded video frames. A light pattern representing a VLC signal captured by the camera (4) is identified in at least one decoded video frame and decoded into a DRM identifier. Distribution of the bitstream is controlled based on a comparison of the DRM identifier and a defined DRM identifier. Hence, VCL is used to add watermarks to recorded video data and where such watermarks can be used to control distribution of copyright or digital rights protected video content.

    Abstract translation: 由用户设备（1,2,3）的相机（4）捕获的编码视频数据的双串接收并被解码成解码的视频帧流。 表示由相机（4）捕获的VLC信号的光图案在至少一个解码的视频帧中被识别并被解码成DRM标识符。 基于DRM标识符和定义的DRM标识符的比较来控制比特流的分布。 因此，VCL用于向记录的视频数据添加水印，并且其中这些水印可以用于控制版权或数字版权保护的视频内容的分发。
