JPEG-2000 Rate Control for Digital Cinema
Recent industry developments have made it clear that although digital cinema signals are image sequences, they will almost certainly be compressed using an intra-frame image compression method such as JPEG-2000 that operates on one frame at a time. This is in contrast to traditional inter-frame video standards such as MPEG that operate on multiple frames at once. Furthermore, recent research has shown that the coding efficiency advantages of inter-frame coding are significantly reduced for 4k digitized film content at the data rates and quality levels associated with digital cinema. This raises a number of important issues related to rate control methods, which have the goal of maximizing quality while also ensuring that the overall post-compression bit rate maintains average and peak values within the limits of the delivery and decoding systems.
