摘要： A method for high quality, fast intra coding usable for creating digital video content. The video image is defined by data points representing original colors. Data points are selected based on a color characteristic, and are arranged into groups. At an initial stage (and at subsequent stages): selecting a subset of data points, using a number of algorithms to generate predicted values of the colors represented by the data points, calculating error values and evaluating mathematical functions to produce cost values, identifying a minimum cost value, establishing a threshold based on the minimum cost and a selection factor, comparing each cost value to the threshold value, and identifying a number of probable best algorithms. One of the probable best algorithms is usable for block size selection and to generate final predicted values of the original color represented by the data points.

摘要： To create information in media content a standardized segment tag associated with macro segments is created. To extract segments from media content, macro segments of the contiguous stream are identified based on the presence of a standardized segment tag associated with each identified segment and data is extracted from each identified segment based on the associated tag. In a device for creating information in media content, a processor identifies macro segments of the contiguous stream and creates a standardized segment tag associated with each segment. A memory stores the macro segments and the standardized tag associated with each segment. A device for extracting segments includes a processor configured to identify macro segments of the contiguous stream based on the presence of a standardized segment tag associated with each segment. The processor extracts data from each identified macro segment based on the associated standardized tag. A memory stores the extracted data.

摘要： A method and computing device for intelligently pre-buffering at access points in an adaptive or scalable stream to optimize trick-play support. The method receives a multimedia content stream from a multimedia content server as a series of segments, each segment including a key frame and corresponding to a predicted seek position in the multimedia content stream, where the multimedia content server delivers at least two versions of each segment, each version reconstructed from at least one encoded component of the multimedia content stream, the versions varying a characteristic of the multimedia content stream. The method determines a likelihood of receiving a seek request from a user to move from a current playout position to one of the predicted seek positions, and determines a size of a buffer for each version of each segment in the multimedia content stream based on the likelihood of receiving the seek request.

摘要： A method and apparatus associates voice metadata with a content item such as a recorded program using a content guide. In one embodiment, a process presents the content guide to a viewer. The viewer makes a first request to select a content item listed in the content guide, and this first request is received by the processor. In response to the first request, the processor presents content information for the selected content item. The content information may include one or more voice metadata options for the selected content item. The method and apparatus may be implemented in a digital video recorder (DVR). A DVR content searching method is also disclosed. In one embodiment, search parameters are received at the DVR, and the DVR searches through an index of voice metadata associated with one or more content items stored at the DVR.

摘要： A method and computing device that allows a viewer to specify a Region of Interest (ROI) in a picture-in-picture (PIP) video signal, and displays only the ROI in the PIP window. The method displays a secondary video signal for a secondary program, and receives a boundary that defines an ROI on the secondary video signal. The method extracts a portion of the secondary video signal, where the portion extracted corresponds to the ROI. The method displays a primary video signal for a primary program in a main window, and displays the extracted portion of the secondary video signal in the main window where the portion of the secondary video signal overlays the primary video signal.
