US Patent 10171825 Parallel compression of image data in a compression device

Method and apparatus of compressing a stream of pictures in parallel in a compression device, where the compression device includes at least a first and a second component, are described. A first portion of a first picture of a stream of pictures is processed in the first component of the compression device, while a second portion of a second picture of the stream of pictures is simultaneously processed in the second component of the compression device according to partial compression statistics associated with the second picture, where the partial compression statistics result from the processing of the second picture in the compression device when compression of the second picture is not yet completed.
