摘要： A video decoder receives (202) compressed video and processes (204) the video to generate decompressed video comprising a plurality of pixels in a sequence of frames. For at least some of the pixels, the video decoder further determines (206), on a pixel by pixel basis, motion vector and quantizer values used to perform compression of the pixels and determines (208) a quality value for each corresponding pixel using the motion vector and quantizer values, wherein the quality value provide a measure of reproduction accuracy of the decompressed video with respect to corresponding uncompressed video.

摘要： A policy enforcement device performs a method for adjusting video compression parameters for encoding source video based on a viewer's environment. The method includes: receiving, from a video receiving device, a video stream identifier indicating a video stream and a source of the video stream, wherein the video receiving device is remote from the source of the video stream; receiving an indication of environmental conditions of a viewer of the video stream using the video receiving device; determining a set of video compression parameters based on the indication of environmental conditions of the viewer; sending the set of video compression parameters to the identified source of the video stream to enable encoding of the video stream to a different compression level.

摘要： A video decoder system receives a user request for non-linear decoding of at least one video frame from a video stream encoded using an Intra macroblock refresh process. The request includes a first frame offset corresponding to a user requested first decoding frame within the video stream for commencing the non-linear decoding. The decoder system: determines an Intra-refresh period corresponding to at least one encoded Predictive frame in the video stream during which all macroblocks in the user requested first decoding frame are Intra encoded at least once; determines a second frame offset as a function of the Intra-refresh period and the user requested first frame offset, the second frame offset corresponding to a second decoding frame within the video stream. Finally, the decoder system decodes the video stream starting at the second decoding frame and suppresses the display of the video stream until the first decoding frame.

摘要： A video tagging method, a video analytics method, and a Computer Assisted Dispatch (CAD) system use incident reports for video tagging and searching. A CAD system is integrated with field-based video surveillance systems to aid in searching video content and subsequent tagging of the video content. The systems and methods can include extracting keywords from a CAD incident report and creating a small, focused, and incident-specific dictionary on which to perform video searching in real-time. The small, focused, and incident-specific dictionary increases tagging accuracy and reduces tagging processing time in the context of video analytics. Further, a multi-pass approach in real-time continually updates and disseminates to video cameras of interest the small, focused, and incident-specific dictionary as the CAD incident report is updated and as the incident of interest plays out.
