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.

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.

Make your graphics look better with an easy-to-use JPEG 2000 decoding component.

J2K-Codec can help game developers, screensaver creators and many others to improve their products–to achieve better image quality and reduce installation package size. The new image compression standard based on wavelet technology has many interesting features not available in the old JPEG, such as alpha-channel and varied resolution levels.

Give it a try–look professional–sell more!
