Although the JPEG 2000 image compression method is 11 years old by now, it’s extremely various features still make it a desirable technology today. Such features are among others the possibility of lossless compression which was missing from the predecessing version of the JPEG standard and the excellent scalability. It also exceeds the previous JPEG version in the achievable image quality which at small and big file sizes is the most noticeable. It is because of the latter that JPEG 2000 is being used widely in professional video processing applications such as high quality video transmission in studios. In order to get a unique image quality, the DCI specification of today‘s digital theaters is based on JPEG 2000. It is a disadvantage for the implementation that unlike JPEG the JPEG 2000’s implementation requires much more resources both at the encoding and decoding site which due to the high resolutions applied makes it unavoidable to implement some parts of it in hardware.

The color- and discrete wavelet transformation, block- and MQ-coder modules implemented by me are capable of meeting the DCI’s even highest expectations of JPEG 2000 and can compete with the public specification of similar IP’s available on the market. The units which are subjects of this thesis can later be controlled by a microprocessor and be a part of a JPEG 2000 compressor.
