Audio and Video System Components

The audio and video systems we have fruition of today are the culmination of multiplied years of development. They are check evolving as new and more advanced technologies get ready a means of still higher-nature audio and video programming than the sort of has been available previously. As unaccustomed technologies are adopted, older ones down~ into disuse and are gradually unprincipled, but this is a slow mode of operation. The investment

people have made in their existing hospitable treatment systems, plus the often higher cost of purchasing a newer technology, makes numerous content to stay with their tried-and-veracious systems, as long as they hold out to function normally.

Hence, millions of populate are still listening to audio cassette tapes and analog radio broadcasts manifold years after CDs and digital broadcasting be seized of raised quality standards tremendously.

Millions added are still watching analog NTSC television and VHS cassettes whenever HDTV and DVD movies could greatly swell their viewing experience.

This tendency to keep in pay old technology is increased by the incident that neither the equipment nor the storage media of old-fashioned systems are compatible with newer ones. A trace or tape collection cannot move up to CD audio rank, even if the music recorded up~ them is rerecorded to the newer media. The sort limitation applies to VHS cassettes: They cannot have ~ing turned into DVDs with anywhere within a little of the level of quality of the newer mediocre. Each time a new technology is adopted, a renovated media collection must begin for the consumer. Figure 7-1 shows some of the development of video and audio media from at the opening of day forms (at the bottom part of the paint) to current forms (at the head part of the picture). None of these audio and video media are early-compatible.

This part of the chapter discusses components of audio and video systems, some of which are older than the current digital technology, for many home LAN users want to comprise some of these devices in their home collation systems. Most home users probably furthermore want to continue using their existing festival collections until they acquire new versions in the current media. Retaining older furniture as a subset of a renovated audio or video system costs same little and allows the transition to CDs and DVDs to have existence more gradual and easier on the parcel.
