scope:

This specification contains all the information necessary to facilitate the exchange of data and control information over the IR medium in the home. The document is divided into five sections (1 - 5):

1 - An introduction to the IR standard

2 - A general description of the IR network design

3 - The specifications of the allowed network topology and configuration rules

4 - The specifications for the use of the IR medium including environmental requirements

5 - The physical layer specifications of an IR device - covers the interface to the higher ISO layers, control channel signal characteristics, encoding, transmitter and receiver characteristics, and device failure modes.

The standard establishes a minimum set of rules for compliance. It does not rule out extended services to be provided, as long as the rules are adhered to within the system. It is in fact the intention of the standard to permit extended services (defined by users) to coexist.

Certain aspects of the standard are defined in other documents. These documents will be referenced when relevant. In the case where a referenced standard conflicts with this document, this document will prevail.
