JP2 w skrocie
JP2
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
MPEG-2 w skrocie
MPEG-2
MPEG-2 was developed as the successor to MPEG-1, scaling video quality from VHS-level to broadcast and studio levels. It underpinned the DVD-Video standard (1996) and digital broadcast systems worldwide (DVB, ATSC, ISDB).
