    摘要: In various embodiments, a dynamic range converter includes a first color space converter to convert a source color space of a source video having a source dynamic range to nonlinear color space signals. A linearizer configured converts the nonlinear color space signals to linearized color space signals having a mastering dynamic range via a piecewise linear interpolation of a transfer function. A color volume transformer applies dynamic color transform metadata associated with the source video on a frame by frame basis to generate master adjusted color space signals from the linearized color space signals. A delinearizer converts the master adjusted color space signals to nonlinearized color space signals via a piecewise linear interpolation of an inverse transfer function in accordance with a display dynamic range. A second color space converter converts the nonlinearized color space signals to display domain signals. Other embodiments are disclosed.

    摘要: A system for searching at least one video signal based on an input text string includes a video processing system that processes the at least one video signal by decoding the at least one video signal, encoding the at least one video signal or transcoding the at least one video signal. The video processing system generates a plurality of text strings that describe the video signal in conjunction with the processing. A memory stores a searchable index that includes the plurality of text strings. A search module identifies at least one matching video of the at least one video signal by comparing the input text string to the plurality of text strings of the searchable index.

    摘要: A device encodes a video signal having a sequence of images into an encoded video signal. The device includes a group of picture (GOP) adaption module that detects a high complexity scene in the sequence of images and that generates GOP adaption data indicating the high complexity scene when the high complexity scene is detected. An encoding module generates the encoded video signal with hierarchical B frames disabled when the GOP adaption data indicates the high complexity scene.

    摘要: A video processing device includes a video processing unit that decodes a video input signal into a decoded video signal in accordance with a video compression protocol, based on uncompressed video frame data. A data object compression/decompression module generates compressed video frame data for storage in a compressed video frame buffer by compressing a plurality of video data objects into a plurality of compressed video data objects, wherein a first subset of the plurality of video data objects are compressed via lossless compression and a second subset of the plurality of video data objects are compressed via lossy compression.
