摘要：
Described is a technology by which an image is transcoded to a desired quality measure (e.g., PSNR). A quality measure of transcoded image data is checked against a desired quality measure, and if a desired quality measure is not achieved, a different quality level is iteratively provided to attempt to re-transcode the image until the desired quality measure is achieved.
