The recent flood of news featuring JPEG 2000 might change your opinion:
HD House Opens in Park City, Utah
The Grass Valley Infinity SD/HD camcorder records to four types of removable media (REV Pro, IEEE 1394, USB and Compact Flash) and an internal buffer. It offers two different codecs (DV and JPEG 2000) built-in, and, with no sub-sampling, the camera produces full 1920×1080 HD images via 10-bit, 4:2:2 processing with JPEG 2000 advanced compression.
New Mexico GIS Users embrace ECW Imagery
ER Mapper is the leading provider of enterprise geospatial imagery solutions. Clients in more than 120 countries use the ER Mapper image processing application to prepare imagery, ECW JPEG 2000 to compress and use imagery, Image Web Server to deploy imagery over the Internet and RightWebMap for integrated web map solutions.
BroadMotion JPEG2000 Codecs are TI eXpressDSP(TM) Compliant
BroadMotion today announced that its JPEG2000 and Motion JPEG2000 codecs have been optimized on the Texas Instruments (TI) TMS320C64x(TM) and TMS320DM64x(TM) digital signal processors and are shipping today. TI has also certified that BroadMotion’s JPEG2000 software codecs are compliant with TI’s eXpressDSP(TM) algorithm interface standard, a set of rules and guidelines with a published Application Programming Interface (API) designed to enable interoperability of real-time DSP algorithms. Such compliance ensures that embedded hardware developers can rapidly prototype their software and significantly decrease their time to market.
Ascent Selects Doremi Servers For Time Zone Delay
Doremi V1-HD and MCS Video Servers are being used for time zone delay at the innovative origination facilities at Ascent Media Network Services Asia, Singapore, and at the Discovery Television and Technology Centre, Sterling, VA, USA. Each of the 15 Doremi MCS-2r2p servers supplied includes four independent channels, two record and two playback, and can delay two video channels with high quality MPEG-2 4:2:2 video compression at up to 50Mb/s. In addition, a Doremi V1-HD server delays a single HD video feed. It uses high quality JPEG2000 video compression and features independent record and play operation.
BroadMotion Delivers Advanced JPEG2000 Encoders and Decoders
After two years of research and development, BroadMotion Inc. today introduced its high performance encoders and decoders for JPEG2000, the new International Organization for Standardization (ISO) image and video compression format. JPEG2000 uses state-of-the-art techniques based on wavelet technology to produce high-quality images and video at low bit rates. BroadMotion’s JPEG2000 technology is designed to facilitate the adoption of JPEG2000 in hardware and software applications for a variety of industries, including digital cinema, photography, security and surveillance.
GDC Technology launches digital cinema solution
GDC Technology which provides digital cinema solutions has announced the successful demonstrations of their digital cinema content solution including JPEG2000 codec, forensic marking and “Digital Censor Key” at CineAsia 2005 in Beijing China.

IntoPIX is a company specializing in JPEG 2000 image compression, content encryption and hardware integration.
IntoPIX offers a wide range of JPEG 2000 compression products: from encoder to decoder, from High Definition (HD 1920×1080) or 2K (2048×1080) format up to 4K format (4096×2160), from single channel to multichannel compression in real time, from lossy up to pure lossless; intoPIX is capable of handling up to 120 frames per second at HD in a single chip. Its products comply with the exacting standards dictated by the Hollywood studios (DCI) and are recognized for their ultra compact implementation on a single FPGA chip.
Today, intoPIX products target the digital cinema, broadcasting, post-production and video archiving market but also other audio-visual applications that require efficient compression that is visually, and even mathematically lossless.
Thus intoPIX technologies are completely suitable for wireless video transmission, cinema or broadcast camera, field recorder and video server applications.

It is already known that JPEG-LS and JPEG-2000 offer very small or (depending on image) no improvement neither in compression ratio nor in speed compared to known since 1990 algorithms that can be encoded in 500 lines C program. There are several companies that made overcomplicated codecs and trying to sell them on the market either in software or in hardware versions pushing JPEG-LS/JPEG-2000 as a new format. None of them is willing to compare their software to known since 1990 median adaptive predictor in combination with fastAC. If they achieve their goal with establishing new format people will be arms twisted into buying their software/hardware. What users need is making MAP+fastAC browser recognizable format. In this case any programmer can write 300 lines codec that wraps raw data into an image, recognizable by browsers. Unfortunately those who are making decisions about which format is browser recognizable are playing deaf.
