HDV in sintesi
HDV
JVC introduced HDV in 2003, recording MPEG-2 compressed HD video on standard MiniDV cassettes. Two profiles emerged: HDV 720p (JVC) and HDV 1080i (Sony and Canon), each trading resolution and frame structure.
JPF in sintesi
JPF
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.
