Any deliverable produced by the project can be found on the ftp site:

Here is a summary of the ACCOPI ftp site content:


/WP1/

WP1.ps: Workpackage 1; Access Control and Copyright Protection for Images, list of requirements
This first deliverable leads to the ACCOPI project philosophy and concludes on the need of a Third Party function.

/WP2/

WP2.ps: Workpackage 2; The ACCOPI Common Functional Model
Following the previously described ACCOPI philosophy, a CFM has been designed in order to fulfil as many as possible listed requirements. The main CFM characteristics are the introduction of Trusted Third Parties, of Trusted Certification Authorities and of copyright protection management functions.

/WP3/

WP3.ps: Workpackage 3; Existing systems study
Here is a deep review of existing systems (DVB, DSS, NagraVision, Eurocrypt, Digicipher, Eurocypher and Videocrypt) which concludes on a comparison with the ACCOPI proposed system, Equi©crypt.

/WP4/

WP4_1.ps: Workpackage 4 Part A; ACCOPI Kernel Simulator
A part of the ACCOPI CFM has been simulated in C++ and PVM after being translated in ASN.1. The results are reported in this deliverable.
WP4_21.ps: Workpackage 4 Part B; Dissemination
This a summary of the contacts established by the ACCOPI consortium with relevant standardization bodies, mainly EBU and DAVIC. The corresponding annexes are not available on the site as their access is restricted to the DAVIC members.

/WP5/

WP5.ps: Workpackage 5; Watermarking
One way to solve the Copyright Protection issue is the watermarking, to encrust an invisible mark inside the image. This document is an overview of it, providing complete watermarking algorithms examples.

X_tms.ps; Does X.tms Fit Between Multimedia Applications and Connection-Oriented Networks?
In this report, we analyse how the Quality of Service and group communication supports are provided by X.tms- the ITU-T recommendation for an enhanced transport service. We also study some clues on how X.tms could exploit "Connection-Oriented Network-like Service" such as the one provided by the future ATM network.
accopitr.ps; The ACCOPI Multimedia Transport Service over ATM
In this paper, we describe how the ACCOPI Multimedia Transport Service (AMTS), which is designed to support multimedia applications, can exploit the features of the ATM networks. More specifically, we discuss the mapping of the group communication topology provided by AMTS on the topology provided by the point-to-multipoints virtual circuits in ATM.
design.ps; On the Design of a Transport Service to Support Multimedia Applications
In this paper, we present early considerations on the design of a multimedia transport service. The proposed design provides not only support for Quality of Service (QoS) and group communications, but also has the property to treat multimedia communications "as a whole". This differs from most of the current transport services which transfer multimedia data as several independent monomedia.
ulg1.ps; Research in Multimedia at the University of Liege
During the last few years, we have been witnessing tremendous changes in the communication environment. Those changes are not only due to the availability of higher data rates in the communication networks but also to the appearance of new application types such as multimedia applications. After a brief introduction to multimedia communications, we will present the research activities in multimedia undertaken at the University of Liege during the last few years.
ulg2.ps; ISO/IECJTC1/SC6 Meeting in Beppu City, Japan: Facts and Perspectives
The Sub-Committee 6 (SC6) of the Joint Technical Committee 1 (JTC1) of ISO/IEC is responsible for the four lower layers of the OSI Reference Model (RM) of ISO. It is composed of several Working Groups (WG). In this report we will essentially report the activities within the WG4 (responsible for the Transport Layer of the OSI RM).

octet-stream.ps;The XPEG system: a software codec for the DCT/MC standard family
This paper describes a software implementation of a complete system for image coding using the recently developed standards, JPEG, MPEG1 and MPEG2. It consists of the video coding level and the system multiplexing in program and transport streams. The simulation software use the common functions of the hybrid DCT/MC coding standards and integrates them using a serial/parallel architecture. The encoder is integrated in the content production of the testbed to be used in the ACCOPI field tests. The decoder contains a bitstream analyser which acts as a bitstream verifier. This aspect is important for security reasons as well as for the inter-operability issue.
