Compact disks (CDs) introduced, which deliver 44.1 KHz samples at a bit rate of
705 Kbps per channel.
The date is approximate but H.261 shows up around here somewhere.
QuickTime 1.0 introduced.
MPEG-1 delivers video on the PC, Internet, and CD format disks.
QuickTime released for Windows.
MPEG-1 Audio layer 3 (MP3) standard. Usable quality attainable at 80 Kbps per
During this year the ITU started work on H.26P. That later became H.263.
They also initiated work on H.26L. That evolved into H.264.
MPEG support in QuickTime demonstrated.
Experimental work and field trials in the United Kingdom by Apple, Oracle, and
British Telecom on computer-based set-top boxes and the distribution of TV via
QuickTime 2.0 and QTVR introduced for Mac OS and Windows.
H.262 and MPEG-2 appear.
H.263 developed for videoconferencing applications.
MPEG-2 Advanced Audio Coding (AAC). Typically operates at about 64 Kbps per
The ITU formed the Video Content Experts Group (VCEG) this year.
QuickTime 3.0 introduces many new features.
QuickTime 4.0 introduces an interactive architecture that is later exploited by
The ITU issues a call for proposals for technology to be included in H.26L.
MPEG-4 Part 2 video being discussed.
MPEG calls for proposals to incorporate compression technologies in MPEG-4
video. ITU responds.
Everyone realizes it would be silly to carry on independently and the Joint Video
Team (JVT) is established. This is a profound example of what other groups
working on a variety of standards should look at and consider doing.
