Integrating Multichannel Sound Into Home Video Systems

Document Thumbnail

The combining of high quality audio with video systems has placed more stringent demands on the localization aspects of the sound field. The apparent sound source location created by the sound field must closely match the location suggested by the video program, if the realism of the presentation is to be maintained. A sound field, created with the traditional two loudspeakers, severely limits the viewing area where both good localization and good spatial effects can be achieved. The inclusion of additional loudspeakers and signal processing techniques developed for the motion picture industry have made it possible to greatly improve the ability of the sound field to fuse the audio and video images over a wide viewing area while maintaining the ability to produce good spatial effects. This paper discusses the requirements for integrating such as a system into the home environment.
