Home Plastic-Fibre Networks based on Home Audio/Video Interoperability


The HOME-PLANET's objective is to demonstrate a consumer friendly In-Home Digital Network (IHDN) that will enhance the consumer's enjoyment and control of entertainment and information. The consortium will demonstrate a user-friendly IHDN solution through a combination of the Home Audio Video Interoperability (HAVi) middleware with its choice of the IEEE 1394 high-speed bus and a plastic optical fibre (POF) physical layer. Through the development of a European source of step index POF (SI-POF) together with the development of high speed resonant cavity light emitting diodes (RCLEDs) and RCLED transceivers, a low cost but high speed (400 Mbps) POF IEEE 1394 based HAVi network will be constructed. The consortium will demonstrate the technology by networking a notebook to a residential gateway and thereby control a digital satellite tuner and home server on the IHDN.

[1] To demonstrate a consumer friendly In-Home Digital Network (IHDN) based on IEEE P1394.b using Plastic Optical Fibre (POF) and Home Audio Video interoperability (HAVi) middleware. Such networks will operate over 50 m and conform to the Digital Video Broadcast (DVB)-IHDN standard.
[2] To Demonstrate a homogenous, HAVi/IEEE1394/POF based application consisting of the remote programming of a home gateway + digital tuner + digital recorder via the Internet.
[3] To develop an optical design capability to optimise the entire optical physical layer.
[4] To develop low numerical aperture step index POF and thereby demonstrate the potential of 1394 SI-POF networks to operate at S400 over 50 m.
[5] To develop 200 Mbps and 400 Mbps 1394 POF transceivers based on 650 nm RCLEDs.
[6] To demonstrate a 200 Mbps fully duplex, single fibre link.

Work description:
The work plan of the HOME-PLANET project rests on several factors. The first is that the IEEE 1394 high-speed bus is rapidly being accepted by the multi-media industry as its preferred choice of data bus. This acceptance is testified by the 1394 standard being adopted by the European DVB standard. The second factor is that the 1394 bus has also been adopted by the Home Audio Video interoperability initiative, which enables end users of digital consumer and computer equipment to effortlessly interact with an ensemble of equipment rather than with individual, stand alone devices. The third factor is the impending ratification of the IEEE P1394.b revision of the 1394 standard will increase the link lengths from 4.5 m to 50 m using plastic optical fibre (POF). It is this timely confluence of factors that not only enable the technical feasibility of a POF In Home Digital Network (IHDN) to be realised but also the excellent prospects for its commercial exploitation.

The project is structured into three phases over 30 months.
Phase I of the project (12 months) concerns the design and development of the project's basic components, 650 nm Resonant Cavity LEDs and POF. These components will go through two design iterations. In this phase the basic design and development of the POF transceivers is also undertaken and will enable a prototype RCLED POF transceiver to be delivered at the end of year 1. This phase will also investigate and identify a single fibre duplex solution.
Phase II of the project (12 months) concentrates on the optimisation of the POF transceivers and POF and their inclusion into Audio/Visual equipment. The end of phase II is marked by the demonstration of a fully characterised POF based IHDN HAVi application. This phase will also demonstrate the capability of single fibre transceivers.
The last phase of the project (6 months), Phase III, is entirely concerned with the promotion of the technology and exploitation activities.

The HOME-PLANET will develop technology that will enable a demonstration of a HAVi based IHDN using plastic optical fibre (POF) as a user-friendly physical medium. At completion the partners will have developed a European manufacturing source of POF and 650 nm resonant cavity LED IEEE 1394.b transceivers. The IHDN demonstration will allow POF networked HAVi equipment to be controlled via the Internet. The project will therefore stimulate a European residential POF IHDN market.
