摘要： Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, using perceptual rules for intelligent dominant color selection. Steps include quantizing the video color space; performing dominant color extraction by using a mode, median, mean, or weighted average of pixel chromaticities; applying perceptual rules to further derive dominant chromaticities via [1] chromaticity transforms; [2] a weighted average using a pixel weighting function influenced by scene content; and [3] extended dominant color extraction where pixel weighting is reduced for majority pixels; and [4] transforming the dominant color chosen to the ambient light color space using tristimulus matrices. A color of interest can be further analyzed to produce a true dominant color, and past video frames can guide selection of dominant colors in future frames.

摘要： Flicker free operation of ambient light sources that emulate video content during low luminance conditions, where the ambient light source is output thresholded so that an on/off change of state of the ambient light source can be initiated after an intensity variable passes one or two thresholds. Output thresholding is used when extracting and processing video content encoded in a rendered color space, which can be decoded into frames tapped by an interframe interpolation process using only color information from selected frames, such as extracting average or other color information from an selected screen regions. Negative gamma correction helps prevent garish or inappropriate chromaticities and lumina.
摘要翻译：环境光源的无闪烁操作，在低亮度条件下模拟视频内容，其中环境光源被输出阈值，使得在强度变量经过一个或两个阈值之后可以启动环境光源的状态的开/关改变。当提取和处理在被渲染的颜色空间中编码的视频内容时，使用输出阈值，该视频内容可以被解码成仅使用来自所选帧的颜色信息的帧间插值处理抽出的帧，例如从所选择的屏幕区域提取平均值或其他颜色信息。负伽马校正有助于防止粗糙或不适当的色度和亮度。

摘要： Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, comprising extracting dominant color information from a video signal and transforming the color information through unrendered color space using tristimulus primary matrices to form a second rendered color space for ambient distribution. Steps include quantizing the rendered color space to form an assigned color distribution, such as by reducing possible color states, or binning to form superpixels; and selecting a dominant color using a mode, mean, median, or weighted average of pixel chromaticities. A color of interest can be further analyzed to produce a true dominant color, and past video frames can guide selection of dominant colors in future frames.

摘要： An electronic programming guide (EPG) system employing a preference engine and processing system that combines explicit rule profile, history profile, and feedback profile data to generate new predictions. Television shows are presumed to be indexed by many features. These features are extracted and counted for TV shows watched (implicit profile), and for TV shows rated by the viewer (feedback profile). These profiles are straightforward to combine with suitably greater weight being given to the feedback information. In addition, explicit profiles can make recommendations that stand alone or may be used to modify recommendations arising from either of the two sources. The modifications may take the form of additive or multiplicative changes to the existing recommendations or some other suitable mathematical form.

摘要： A method and apparatus are disclosed for recommending items of interest to a user based on recommendations made to one or more third parties. The recommendation scores generated by a primary recommender are influenced by recommendations generated for one or more third parties, such as a friend, colleague or trendsetter. The disclosed recommender corroborates with other recommenders when recommending items of interest and adjusts a conventional recommender score based on third party recommendations. The third party recommendations may be a top-N list of recommended items for a given third party, and may optionally include a recommendation score and an indication of whether or not the third party actually selected the recommended item. A recommender evaluates the viewing or purchase habits of a user and communicates with one or more other recommenders to determine the items that are being recommended by such other recommenders.

摘要： A method and apparatus are that restrict access to digital content to an authorized user on one or more systems using biometric watermarks. The disclosed biometric watermarking techniques allow an authorized user to be uniquely identified. Access to digital content is restricted to digital content in accordance with the present invention by embedding a biometric watermark, such as a biometric image, in the content. Thereafter, a user can only access the content if a biometric sample of the user matches the embedded biometric watermark. In one variation, the user can only access the content if the biometric sample is a live biometric sample. The embedded biometric watermark optionally includes information describing a system employed by the user to obtain the content. The user can optionally be permitted to access the content, without a biometric evaluation, if the content is on a system that has been previously authorized for the user using a biometric evaluation.
