Abstract: Stereo speakers may look and even sound like always, but in the majority of systems, perceptual similarity to source or playback ends there. Virtually everything between a performance and its ultimately analog reproduction is coded. The same applies to image creation and generation: a camera lens still gathers light, which is generated by the viewer's TV screen, but the widespread popularity of digital acquisition, nonlinear editing, and cable or satellite-direct transmission means that every frame is probably sampled, quantized, transformed, processed, and generally squeezed within an inch of its just-noticeable-degradation, enroute to a receiver's analog display. Beyond the obvious, this is important because prior to digital transmission, sampled images are compressed. Invariably, that's simple economic necessity; of physical necessity, compression means loss. And finally, practical necessity dictates that more control of the visual image rests with those who stand between the creators and the audience.
