Abstract: Device logic in a mobile device configures a processor to capture a series of images, such as a video, using a consumer-grade camera, and to analyze the images to determine the best-focused image, of the series of images, that captures a region of interest. The images may be of a textured surface, such as facial skin of a mobile device user. The processor sets a focal length of the camera to a fixed position for collecting the images. The processor may guide the user to position the mobile device for capturing the images, using audible cues. For each image, the processor crops the image to the region of interest, extracts luminance information, and determines one or more energy levels of the luminance via a Laplacian pyramid. The energy levels may be filtered, and then are compared to energy levels of the other images to determine the best-focused image.

In addition, by creating a checksum corresponding to a portion of the transport stream, integrity verification may be performed on a streaming data file.

Abstract: A method and apparatus for reducing the bitrate of a given datastream is provided. The bitrate of a given datastream is reduced by altering the payload of an incoming packet, while still providing sufficient data as to not cause a malfunction within the receiving node. The altered payload represents data which will trigger commonly used error concealment methods, within the receiving node. The determination as to which packets undergo alteration is based on a relationship between network congestion and the priority of a given packet. A packet's priority is measured in terms of its effect on the regeneration of high quality signal. As the need to reduce the bitrate of a given datastream increases, the occurrence of packet alteration increases.
