Stereo Audio Technology for Television and Video: An Overview
Stereo audio and video technologies have developed for many years essentially as separate entertainment industries. Somewhat independent of both, motion picture technology has evolved to a highly refined state with high resolution images and multichannel surround audio. The development and refinement of the consumer video cassette recorder, the optical video disc player, large screen projection television systems, satellite transmission distribution systems, cable television systems, and stereo broadcast television systems have all come together to significantly change the consumer's perspective of home entertainment. Often referred to as the marriage of audio and video, it is possible today for a consumer to experience broadcast quality video with digital audio on a large screen television system with multiple channel surround audio in the home. In spite of the fact that all of this is possible with available hardware and software, most consumers and audio/video professionals are only technically familiar with portions of the technology involved. Rapidly changing technology and the complexity of such systems are major factors contributing to this lack of awareness. As is typical of emerging technologies, a lack of standards and accepted practices as well as economic uncertainties are serious limitations to growth.: The Audio Engineering Society Conference on Stereo Audio Technology for Television and Video has as its prime goal the task of bringing audio and video professionals up-to-date on this emerging technology with an eye on promoting growth through better technical and economic understanding.
