    Abstract: A hybrid compression method for compressing images is provided. The method identifies a first set of image components to be compressed by a lossy compression format and a second set of image components to be compressed by a lossless compression format. The method then encodes the first set of image components according to the lossy compression format and encodes the second set of image components according to the lossless compression format. The method then generates a compressed structure that includes the lossy-compressed first set of image components and the lossless-compressed second set of image components.

    Abstract: A method for decoding a compressed video data sequence containing one or more coded pixel blocks. The compressed video sequence is buffered. Prediction information for each of the coded pixel blocks is reviewed. One or more groups of coded pixel blocks are formed based on the reviewed prediction information such that the coded pixel blocks within a given group have similar prediction dependencies and/or at least do not depend on a reconstructed pixel within a group of received pixel blocks to enable parallel decoding. The formed groups are scheduled for processing and subsequently decoded to produce a decoded video data sequence.

    Abstract translation: 一种用于解码包含一个或多个编码像素块的压缩视频数据序列的方法。 压缩视频序列被缓冲。 回顾每个编码像素块的预测信息。 基于所检查的预测信息形成一组或多组编码像素块，使得给定组内的编码像素块具有相似的预测依赖性和/或至少不依赖于所接收的像素块组内的重建像素 启用并行解码。 形成的组被调度用于处理并随后被解码以产生解码的视频数据序列。
