Abstract: The present invention generally relates to systems and methods for the efficient and secure creation of unique identifier associated with submitted URLs and the transmission and processing of encrypted signals by a receiving device, and in particular an audio transmission and processing of encrypted unique inaudible signals by a receiving device that may direct the receiving device to initiate an action, such as directing the receiving device to request the associated URL to then access a specific Uniform Resource Locator (URL) or other digital content. The decoding and processing of the transmitted signal is operated on prior to the signal being played through the receiving devices speaker system(s). Consideration to the available signal bit rate is an important aspect of the systems operational integrity.

Abstract: 一种视频处理方法及电子设备，涉及视频领域；所述视频处理方法包括：确定目标视频的标识图像，该标识图像包含目标视频的版权信息；在目标视频的所有帧图像中确定目标帧图像；合并标识图像与目标帧图像，得到混合帧图像，生成的混合帧图像用于替换目标视频中的目标帧图像。被添加的版权标识在目标视频中的隐藏效果较好，基本不会对画面产生遮挡，又难以被侵权者发现，降低了被恶意破坏或消除的可能性；处理过程对机器算力及性能要求较低；而且侵权追溯的可靠性较高。

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to use station identification to enable confirmation of exposure to live media. Example apparatus disclosed herein include a watermark data segmenter to determine a media identifier conveyed by a watermark, a detection time determiner to determine a time at which a media meter detected the watermark from a media presentation by a media device, a reference identifier to query a library of reference signatures for a reference signature associated with the media identifier of the watermark and associated with a reference timestamp corresponding to the time at which the media meter detected the watermark, and a viewing type determiner to determine whether the media presentation is live or time-shifted based on whether a result of the query indicates the reference signature does not exist in the library of reference signatures.

Abstract: A method includes accessing an audiovisual composition comprising a target video segment and a source video segment. The method also includes, in response to presence of the target video segment and the source video segment in the audiovisual composition: accessing a first keyword associated with the source video segment; and calculating a first relevance score for the first keyword relative to the target video segment based on a temporal position of the source video segment in the audiovisual composition and a temporal position of the target video segment in the audiovisual composition; accessing a textual query comprising the first keyword. The method additionally includes: generating a first query result based on the textual query, the first query result comprising the target video segment based on the first relevance score; and at a native composition application, rendering a representation of the first query result.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to identify media for ahead of time watermark encoding. An example apparatus includes a processor to determine a first identifier associated with first media based on a query including the first identifier, a first scheduled broadcast time of the first media, and a first duration of the first media; and a comparator to: in response to determining a database includes a second identifier associated with second media, determine whether a second duration of the second media at a second scheduled broadcast time overlaps the first duration of the first media at the first scheduled broadcast time; and in response to determining that the second duration of the second media at the second scheduled broadcast time does not overlap the first duration of the first media at the first scheduled broadcast time, store the first identifier in the database.

Abstract: A content processing system obtains an identification associated with a device configured to receive content, generates a digital watermark reflecting the receiving devices identification, provides watermarked content by including the digital watermark in the content, and transmits the watermarked content from an edge computing device to the receiving device for the playback. The digital watermark is not visually observable during playback of the watermarked content, and it enables tracking of transmission of the watermarked content.
