    Tuesday 13 November 2007 RE: Response to the proposed BSkyB digital terrestrial television services consultation I wish to start by personally thanking you for allowing me to respond to the plans that British Sky Broadcastings plans to launch their Picnic platform on Digital Terrestrial Television, including the launch of the following services: z Sky Sports One; z A children's channel/Sky Movies SD One; z A factual channel/Sky News/Sky One; z Sky News (if BSkyB is given permission to launch a fourth service on DTT using MPEG-4 encoding); z Broadband up to 16Mbps and a telephony service. I wish to begin by giving an idea of my thoughts on the proposal by BSkyB before I answer the questions in the consultation document. Introduction 1. Regarding the use of by BSkyB and NDS Group, the VideoGuard conditional access technology for its pay television services. According to the press release that was released by BSkyB on the 8th of February 2007,1 the service will use a highly secure conditional access system similar to the one BSkyB uses for its digital satellite services, Sky Digital and FreesatFromSky. I also understand that Sky has also stated that viewers will require a new set-top-box to access the new service. In the past, since the launch of the Sky satellite television service in February 1989 via the Astra satellite, BSkyB have always used NDS Group technology to encrypt and protect their own branded services, with both the VideoCrypt and VideoGuard conditional access systems for their Sky analogue and digital satellite services respectively.

  • Study on the Use of Conditional Access Systems for Reasons Other Than The
    Study on the use of conditional access systems for reasons other than the protection of remuneration, to examine the legal and the economic implications within the Internal Market and the need of introducing specific legal protection Report presented to the European Commission by N. Helberger N. A. N. M. van Eijk P. B. Hugenholtz Institute for Information Law (IViR) University of Amsterdam Preface The study, commissioned by the Directorate-General for Internal Market and Financial Services (DG XV) of the Commission of the European Community, offers an analysis of the use of conditional access systems for other reasons than the protection of remuneration interests. The report also examines the need to provide for additional legal protection by means of a Community initiative, such as a possible extension of the Conditional Access Directive. The report will give a legal and economic analysis of the most important non- remuneration reasons to use conditional access (CA), examine whether services based on conditional access for these reasons are endangered by piracy activities, to what extent existing legislation in the Member States provides for sufficient protection, and what the possible impact of the use of conditional access is on the Internal Market. Furthermore, the study analysis the specific legislation outside the European Union, notably in Australia, Canada, Japan and the US, as well as the relevant international rules at the level of the EC, WIPO and the Council of Europe. This study was written by Natali Helberger and Dr Nico A. N. M. van Eijk at the Institute for Information Law (IViR), University of Amsterdam under the supervision of Professor P.

Telewizji i Radiofonii Cyfrowej Warszawa, wrzesień 2009 Streszczenie Niniejszy dokument opisuje zasady działania systemów dostępu warunkowego 1 stosowanych obecnie w telewizji cyfrowej systemu DVB2 oraz zawiera przegląd najpopularniejszych rozwiązań spotykanych w Polsce i innych krajach europejskich. Opracowanie powstało w podgrupie ds. CAS Grupy problemowej ds. techniki i sprzętu w celu ułatwienia wyboru systemu dostępu warunkowego dla polskiej DTT zapewniającego niezbędny poziom bezpieczeństwa i szeroką akceptację rynku. Dostęp warunkowy stosuje się do zabezpieczenia treści rozprowadzanych w sieciach telekomuni- kacyjnych przed nieautoryzowanym dostępem. Obok DRM jest to obecnie podstawowy sposób ochro- ny praw autorskich i pokrewnych w erze cyfrowego przesyłania i rejestrowania informacji. Dostęp warunkowy polega w zarysie na spowodowaniu, że transmitowana informacja o obrazie, dźwięku i danych pozostaje nieczytelna dla odbiornika niewyposażonego w odpowiednie środki techniczne. System dostępu warunkowego stosowany w polskiej DTT powinien: – być wygodny i przystępny dla użytkownika, – wykorzystywać w jak największym stopniu wspólne elementy odbiornika-dekodera, – być odpowiednio bezpieczny a zarazem elastyczny i niezbyt kosztowny, – pozwalać na konkurencję wśród dostawców treści i usług oraz producentów odbiorników.

  • ANNEX 6 COMMENTARY on the CONSULTATION DOCUMENT in This Annex 6 of Sky's Response We Provide a Non-Exhaustive List of the Erro
    NON-CONFIDENTIAL VERSION ANNEX 6 COMMENTARY ON THE CONSULTATION DOCUMENT In this Annex 6 of Sky’s Response we provide a non-exhaustive list of the errors in Ofcom’s Consultation Document, which are not identified elsewhere in this Response. The significant number of errors, inaccuracies and misconceptions suggests that Ofcom has an inadequate understanding of the context in which pay TV services are provided in the UK and elsewhere. A proper appreciation of that context is an essential prerequisite to accurate analysis of the sector. Section 3 Overview of the UK pay TV market ¶ 3.13 “An estimated one million households also receive free-to-view digital satellite.” This appears to be Ofcom’s own estimate of the number of households who use a Sky set-top box to receive television services, but do not subscribe to Sky’s DTH pay TV services. (No source is provided for the estimate.) If this is the case Ofcom should note that the estimate of one million households is subject to a wide margin of error, being based, Sky understands, on an arbitrary assumption that a certain (constant) proportion of churners from Sky’s DTH pay TV services continue to use their set-top boxes to receive digital free to air television services. It is probable that the actual number of such households is substantially higher than this estimate. Moreover, this reference fails to note that all 8.8 million UK and ROI subscribers to Sky’s DTH pay TV service, and subscribers to other DTH pay TV services, also receive “free-to-view digital satellite”.
