    Abstract: There is provided a lossless video compression method for an H.264 codec. A lossless video compression method for an H.264 codec according to an aspect of the invention may include: dividing an image to be compressed into n (n is a natural number) pixel regions; compressing the n pixel regions to convert the n pixel regions into n variable length compression codes; and generating an address for writing or reading the n variable length compression codes by patterning a size variation of the n variable length compression codes, thereby achieving lossless compression of data to be written in an external memory and allowing for access to data at an arbitrary location.

    Abstract translation: 为H.264编解码器提供了无损视频压缩方法。 根据本发明的一个方面的用于H.264编解码器的无损视频压缩方法可以包括:将要压缩的图像划分为n(n是自然数)像素区域; 压缩n个像素区域以将n个像素区域转换成n个可变长度压缩码; 以及通过对n个可变长度压缩码的大小变化进行构图来生成用于写入或读取n个可变长度压缩码的地址,从而实现要写入外部存储器的数据的无损压缩,并允许访问任意位置的数据 。
