System and method for compressing and decompressing of differentially encoded video streams. I-frames of the encoded video stream may be relatively compressed and decompressed, thereby reducing video data size of an already encoded video stream. Compression and decompression may be lossless processes and may typically require relatively low processing power and small memory sizes.

System and method for relative storage of video data

A method, apparatus and a computer readable medium for skipping macro blocks of a compressed video. The method includes, for at least one INTER frame, saving a set of macro blocks including at least one of a macro block having a motion vector greater than a predetermined motion vector threshold, a macro block having positional correspondence to at least one macro block having a motion vector, a macro block having a size greater than a predetermined macro block size threshold, and a macro block having positional correspondence to a second macro block in a previous group of pictures, the second macro block having a motion vector. The method deletes and marks as skipped one or more remaining macro blocks, and merges the set in an order to create a compressed frame including a skipped macro block. The processor implements the method, and the computer readable medium contains processor instructions.

System and method for enhancing compression using skip macro block on a compressed video

Embodiments of the invention are directed to a system and method for controlling visual parameters of a capturing device to minimize clipping and saturation according to predefined parameters. The method may include processing pixel values of a current input frame of a received video signal captured by a capturing device; accumulating processing results of the current input frame to processing results of one or more previous input frames and calculating a desired dynamic range based on pre-determined user parameters. The processing may further include checking if the accumulated results are within the desired dynamic range and determining if adjustment is desired. If the accumulated results are not within the desired dynamic range, adjusting visual parameters for a subsequent input frame, by controlling the capturing device and if the accumulated results are within the desired dynamic range maintaining current visual parameters of the current input frame for the subsequent input frame.
