The Consumer Electronic Bus Committee of the EIA has released a major portion of the EIA Home Automation Standard. It will be released (after resolving suggestions and comments) as EIA Interim Standard #60. Currently the parts of the proposed standard are: Power Line Physical Layer and Media Node Power Line Symbol Encoding sublayer Data Link Layer Node Logical Link Control Sublayer Node Medium Access Control Sublayer Description of the Node Network Layer Node Network Layer Application Layer CAL Specification A couple of tutorials have been held on CEBUS. There will be one 23rd in Atlanta, GA at the OMNI International at CNN following the Home Builder's Show. EIA address: 2001 Eye Street, N.W. Washington, DC 20006 (202) 457-4900 From the latest EE Times: Philips has formed a joint venture with Mashsushita to establish the D2B, a domestic digital bus that links audio and video entertainment products in the home. Thomson Consumer Electronics and Sony have agreed to support and promote the standard which is also backed by the International Electrotechnical Commission [???] D2B signals can be carried over home automation standards including Japan's Home Bus Systems, Europe's Esprit Home System and the United States' CEBus. From an EIA mailing: A company in Texas has published a summary of Suggested Methods of Avoiding CEBus/X-10 interaction. They compare about 7 possible techniques including: - No avoidance - time multiplex CEBus and X-10 packets - Insertion of a 'null' symbol in CEBus packets - require 'short' CEBus packets on the powerline - Move CEBus fequency - Develop a X-10 transparent CEBus 'jammer' - FSK Transmission (Patented by Westinghouse) The CEBus committee has about a half-dozen references on the interaction between X-10 and CEBus. Companies working on CEBus: The following working groups: Language, TP, RFBus, Infrared, CX are made up of people from the following companies: AISI, GE, RMC Research, GE/RCA, Matsushita, ATT, Philips Laboratories, CCI, Diablo Research, CyberLynx, Zenith, The Systems Group, TI, Boulder Software Engineering, US West, Panasonic, Universal Electronics, D&G Electronics, RF Monolithics, Radionics, Ademco, Intellon, Sony, Scientific Atlanta, Leviton, CCI etc. This list is as of October 1989. nivek Aka : Kevin Dowling Bell: (412) 268-8830 Arpa: nivek@rover.ri.cmu.edu Mail: Robotics Institute Carnegie Mellon University Pgh, PA 15213-3890 ]
