Abstract
This paper studies the idempotence of H.264 intraframe multi-generation coding. We analyze the H.264 transform and quantization and reveal that for some quantization parameters there always exists at least one clipping compensation matrix to make the H.264 intraframe multi-generation coding idempotent as long as the same prediction mode and the same quantization parameter are selected for each coding generation. In addition, an idempotent H.264 intraframe multi-generation coding procedure is presented.
