A lossless bi-level (black and white) image compression technique. JBIG is intended to replace G3 fax algorithms. The JBIG technique can be used on either gray-scale or color images. Some of the applied techniques have a strong resemblance with the JPEG standard. Commercially available implementations of JBIT have been scarce, but some find use in remote printing of newspapers.
Industry:Software
A group comprised of the EIA, the IEEE, the NAB, the NCTA, and the SMPTE. The JCIC created the ATSC in 1982 to handle all of the new advances in TV, including HDTV. The ATSC has since grown to 52 member and observer organizations.
Industry:Software
Compression technique for still images, such as photographs, a single video frame, etc. JPEG can be used to compress motion video. However, it is not as efficient as MPEG which has been optimized for motion video compression applications.

ISO/IEC DIS 10918-1 begins with a digital image in the format Y, CB, CR (such as defined in CCIR 601-2) and provides several levels of compression. Predictive coding and transforms are employed, with the higher compression ratios selectively recognizing the decrease in human visual acuity with increasing spatial frequencies. It is optimized for about 15:1 compression. As increased data storage and increased processing capabilities are becoming available, there is exploration of adapting JPEG-1 for application to successive frames in real time; i.e., full-motion JPEG.
Industry:Software
ISO/IEC CD 11172 describes procedures for compliance testing in applications of JPEG-1.
Industry:Software
A collection of optical/magnetic disks used for storing data.
Industry:Software
Color information for a pixel packed into one word of memory data. For a system with few colors, this packed pixel may require only a part of one word of memory; for very elaborate systems, a packed pixel might be several words long. See Planar.
