International Transmission of Digital Television and Radio

Objective

This project aims to:

- provide a complete inventory of the existing situation inside Eurovision and the European broadcasting scene regarding television and radio transmissions
- study an evolutionary approach for the introduction of international digital television and radio exchanges in Europe.
This project aims to provide a complete inventory of the existing situation inside Eurovision and the European broadcasting scene regarding television and radio transmission and to study an evolutionary approach for the introduction of international digital television and radio exchanges in Europe. 5 reports covering different aspects of the study have already provided the basis for mutually beneficial discussions. These are outline of the Eurovision network, evolution scenarios for the Eurovision network, integrated broadband communication (IBC) applied to the Eurovision network, proposals for the Eurovision network and Eurovision's progress, validity of an evolutionary decision. Work done since these reports has been largely to initiate the desired changes in the networks. Much has been done in identifying equipment for use on the second generation of Eutelsat satellites. Contractual negotiations with Eutelsat over the use of capacity on one of these satellites are now complete, and Eurovision and Euroradio services have access to this since January 1993. The implementation of earth stations is also under way. Full digitization of the Eurovision Network is foreseen for the end of 1997.
Technical Approach

This theoretical study is to determine the best evolution for the introduction of international digital television and radio exchanges at the European level.

The Technical Centre of the EBU has access to input and feedback from 97 Active and Associate Members in sixty- six countries world-wide. The centre actively participates in standardisation through contact with the ITU, ETSI and other regulatory bodies, as well as being manager of the Eurovision network.

Many aspects of the work remain, including the development of TMN and access control management concepts for the Eurovision network.

One further deliverable remains: 'International transmission of TV and radio in the 21st century - an integrated debut?', due November 1992.

Key Issues

- Capabilities of present (analogue) terrestrial and satellite links.
- New measurement methods and equipment to evaluate digital transmissions.
- Signal coding to provide contribution quality, yet still allow easy conversion to public digital broadcast television standards.
- ATM and its consequences on high-quality visual material.
- Avoiding impediment to the introduction of HDTV transmission.

Achievements

Five reports covering different aspects of the study have already provided the basis for mutually beneficial discussions with other Part I projects:

- Outline of the Eurovision network
- Evolution scenarios for the Eurovision network
- IBC applied to the Eurovision network
- Proposals for the Eurovision network
- Eurovision's Progress - Validity of an evolutionary decision

Work done since these reports, has been largely to initiate the desired changes in the networks. Much has been done in identifying equipment for use on the second generation of Eutelsat satellites. Contractual negotiations with Eutelsat over the use of capacity on one of these satellites are now complete, and it is hoped that Eurovision and Euroradio services will have access to this from January 1993. The implementation of earth stations is also under way.

Expected Impact

Ways in which the Eurovision network could be operated as part of a future IBC network will be indicated. It is hoped that the timing of this work will optimise the evolution of the Eurovision network. Pre-competitive liaison in RACE should help ensure that cost effective and uniquely standardised services and equipment can result.

As well as representing the needs of broadcasters in the evolution to IBCN, the project acts as an additional point of contact between RACE and standardisation bodies, ensuring that effort is not needlessly duplicated.
