Abstract

JPEG2000 technology has been adopted even for encoding motion pictures because of its high coding performance and the scalability of the stream format. Since it includes the additional advantage of employing intra frame coding technology such as JPEG2000, it allows drastic reduction in the latency accompanied by encoding and decoding process can be extremely reduced. On the other hand, a low delay transmission has been required especially for a FPU (Field Pick-up Unit) terminal or a piece of wireless camera equipment which may be utilized for a real-time remote hookup. In many such terminals, compression coding was conducted by typical MPEG-2 video, and the codec latency of more than 300 msec was forced basically from its coding algorithm. In this paper, HDTV is assumed to be a typical video application, and an optimal rate control mechanism for the JPEG2000 encoder is introduced as a key technology to achieve a low delay in transmission while maintaining high coding performance. Our study introduces advanced key technologies as yet unrecognized officially. Coding experiments using those technologies confirmed that significant coding delay elimination was achieved when compared to conventional encoding schemes.
