The Consumer Electronic Bus infrared system

The Infrared (IR) Physical Layer definition for the Electronic Industries Association´s (EIAs) Consumer Electronic Bus (CEBus) standard was circulated for comment and vote in the early part of 1990 and was approved after alteration to reflect some of the comments. The author describes the IR Physical Layer specification and some of the network implications of using IR. It is noted that the CEBus IR system represents an effective method of achieving single-room remote control and access to the housewide network. No new technology is used; the standard simply extends current product development trends to provide a method of IR communication which is orthogonal to existing systems. The multiple levels of complexity allow the most cost-effective implementation for the application
