COMPRESSION PICTURE CODING ALGORITHM FOR PHOTOGRAPHIC VIDEOTEX " ( REF . 563 : B/84 )
THE PURPOSE IS TO DEVELOP WITH A GROUP THAT IS REPRESENTATIVE BUT SMALL ENOUGH TO BE EFFECTIVE , A HIGH COMPRESSION PICTURE CODING METHODOLOGY THAT CAN BE APPLIED TO TELEVISION SIGNALS . THE FINAL GOAL OF THE WORK IS THE DEFINITION OF A SELECTED CODING TECHNIQUE AS A POSSIBLE EUROPEAN STANDARD FOR PHOTOGRAPHIC VIDEOTEX ON ISDN .

R AND D AREA 4.4 : ADVANCED MULTI-MEDIA STORAGE AND RETRIEVAL SYSTEMS
DESCRIPTION
INFORMATION TECHNOLOGY AND OFFICE AUTOMATION ARE FUNDAMENTALLY CONCERNED WITH THE STORAGE , ACCESSING AND MOVEMENT OF INFORMATION , COVERING DATA , TEXT , GRAPHICS , VOICE , IMAGES AND OTHER FORMS . INVESTIGATIONS LEADING TO THE DEFINITION OF AN ADVANCED DATA-BASE MODEL FOR OFFICE APPLICATIONS AND STUDIES OF THE SECURITY , PRIVACY , AUTHORITY OF ACCESS AND INFORMATION DISTRIBUTION ARE FUNDAMENTAL TO A WIDE RANGE OF OFFICE SYSTEMS RESEARCH .
THE PROPOSED RESEARCH IS ORIENTED TOWARD CONSTRUCTION OF A NUMBER OF EXPERIMENTAL PROTOTYPE OFFICE INFORMATION SERVERS , AND THE OPERATION OF THESE IN REALISTIC CONDITIONS , ALONE AND IN ASSOCIATION WITH EACH OTHER , TO GAIN PRACTICAL EXPERIENCE IN THE SYSTEMS IMPLICATIONS OF BUILDING THESE SERVERS , LOADING THEM WITH PRACTICAL INFORMATION AND USING THEM IN A REALISTIC WAY .
THE WORK IS THEREFORE DIVIDED INTO THREE GENERAL CLASSES : SYSTEMS ISSUES , USAGE AND NEEDS , AND COMPONENTS .
SYSTEMS ISSUES : THESE COVER THE DESIGN AND OPERATION OF OFFICE INFORMATION SERVERS , INCLUDING HIGH-PERFORMANCE FILTERS AND INVESTIGATIONS OF NEW INFORMATION MODELS AND THE DEVELOPMENT OF METRICS RELATING TO THESE . SERVERS MUST BE CONSIDERED IN RELATION TO THE OTHER COMPONENTS OF A COMPREHENSIVE OFFICE SYSTEM INCLUDING OTHER INFORMATION SERVERS AND THE DISTRIBUTION OF INFORMATION AND FUNCTIONS BETWEEN THEM . WORK ON THE FILING INTERFACE-RELATED ASPECTS OF QUERY LANGUAGES AND DECLARATIVE CONTENT LANGUAGES IS IDENTIFIED .
USAGE AND NEEDS : THIS TOPIC ADDRESSES THE NATURE OF THE INFORMATION ( DATA , TEXT , GRAPHICS , IMAGES ETC . . . . ) THAT WILL BE HELD IN OFFICE INFORMATION SERVERS IN TERMS OF QUALITY , QUANTITY AND COMBINATION AND THE USAGE OF THAT INFORMATION . AN INTERNAL ADAPTIVE INTERFACE IS TO BE INVESTIGATED , THAT RESPONDS TO THE NEEDS AND EXPERIENCE OF USERS .
COMPONENTS : THE DEVELOPMENT OF HARDWARE , SOFTWARE AND SYSTEMS ELEMENTS THAT WILL BE INCORPORATED INTO ADVANCED FILING SYSTEMS , PRIMARILY IN INFORMATION SERVERS , BUT ALSO IN ADVANCED WORKSTATIONS . THESE INCLUDE FILTERS , THE SYSTEMS MANAGEMENT ISSUES RELATING TO USING OPTICAL DISCS IN ADVANCED OFFICE SYSTEMS , THE SYSTEMS TECHNIQUES REQUIRED TO ACHIEVE VERY HIGH PERCEIVED RELIABILITY , AND THE APPLICATION OF ADVANCED INFORMATION PROCESSING TECHNIQUES TO ADVANCED FILING AND RETRIEVAL SYSTEMS .
