See also Planning Videoconference Rooms Environment The environment for videoconferencing requires particular attention if the highest quality sound and vision signals are to be transmitted and received. This is equally true whether sophisticated, dedicated videoconferencing equipment or the simpler desktop plugin cards are being used.

The CODEC has two components: the COder and the DECoder. The COder takes the local sound and vision signals and converts them into a form that can be transmitted over a digital network. The DECoder performs the reverse function i.e. it takes the remote site’s digital signals from the network and converts or decodes them into a form that enables the picture monitor to display images and the loudspeaker to radiate sound from the remote site. A CODEC is thus required at each end of the link for a videoconference.

See Appendix A. The camera converts light images into an electrical signal so that it may be displayed, recorded or transmitted. The camera lens focuses the images onto a light sensitive layer sometimes referred to as a Charge Coupled Device or CCD.
