MJ2 is a video category category format that contains the motion sequence of JPEG 2000 images. This video encoding system, which uses JPEG 2000 intraframe compression technology, was developed at the Fraunhofer Institute of Integrated Circuits (FIS). Since November 2001, it has existed as an international ISO / IEC standard. The codec is based on a discrete conversion. Compared to the MPEG family used in codecs, it performs encoding in two areas simultaneously. Both in spatial and in frequency. In this case, there is no need to split the images into blocks. Only intra-frame compression is used for each frame, and inter-frame coding is not applied. A distinctive feature of MJ2, that is, Motion JPEG 2000 Video Clip, is that it can be scaled. And not only in terms of frame size. And in quality, that is, in terms of video stream speed, too. The decomposition features are such that each frame can have its own copies, which are two times less vertically and horizontally. Since it is possible to compress without loss, it is possible to use this codec in the medical industry. After all, it is necessary for images to have high accuracy. Synchronization with video supports embedded audio.
JBG is a graphic format for raster images, which is usually referred to as the Image JBIG 1-bit Raster file type. The purpose of the format is to store images - both black and white and color. Compared to other similar formats, it has a smaller file size. The .jbg file extension is related to the fact that the image is compressed without loss and is called JBIG. It was developed by the Joint Bi-level Image Experts Group. A .jbg file stores a 1-bit bitmap in JBIG graphic format. It is used as a standard for fax machines. JBIG is a lossless image compression standard. JBIG was developed primarily to compress facsimile images. However, it can be effectively applied to other classes of images. The format uses a variant of arithmetic compression, which is patented by IBM and known as Q-coder. A JBG file is a Jarnal background image. Jarnal is a cross-platform program that is written in Java for notes, thumbnails, and PDF annotations. It functions like a regular notebook with a small difference. It is believed that it can also be used as a stylus on a tablet.
