Discrete Wavelet Transform.
The European Broadcasting Union governs the standardization
of TV in European markets.
European Computer Manufacturers Association.
The video and audio is compressed by the codec to form an
elementary stream that just contains one kind of media. These
are then multiplexed together to form a program stream.
An early Java-based codec that was interesting but never
became widely used.
The TechSmith Ensharpen codec is designed for screen-capture
applications. It is quite efficient for that use but has limited
availability across platforms.
The coding of the string of DCT coefficients that are created by
the DCT encode of a macroblock.
A networking system for connecting computers together.
The networking outside of your own internal network or
intranet is called an extranet.
Full Common Intermediate Format. An alternative to CIF that
qualifies the size in contexts where QCIF might be mentioned
Forward Error Correction.
The order in which the odd or even fields of an interlaced raster
An interface designed to support hard disks and fast video
transfers. Originally developed by Apple Computer, it has
become ubiquitous as an interface for downloading material
from portable DV cameras.
Flexible Timeline Multiplexor introduced with the MPEG-4
systems layer. This allows some very sophisticated interactive
and multimedia services to be constructed and also solves one
major problem with MPEG-2 where timelines in program
streams are difficult to splice and trigger interactive events from.
This is an interesting codec that uses edge-based coding.
Interestingly, as the compression ratio increases and the quality
decreases, the image begins to resemble a cell-animated cartoon
but the edge detail remains until the very last.
A motion-compensation vector used when the video is playing
forward in the normal way.
