Technologies in MPEG-4 AVC FRExt for improving subjective picture quality in high-definition video compression

These tools have significantly improved subjective picture quality especially for HD applications, e.g., the next-generation optical disc packaged media such as the Blu-ray disc (BD) ROM.
