Embodiment Construction

[0021] The present invention relates to a method of transferring data between a recording and / or reproducing device and a remote unit interconnected via a network.

[0022] In general, the present invention relates to a client / server architecture. On the client side, the recording and / or reproducing device is, for example, a home DVD player or a personal computer DVD player (with built-in internet connection and protocol stack), or a GPRS equipped with a Small Format Factor Optical SFFO disc (General Packet Radio Service) or third generation mobile phones. On the server side, a remote unit is a computer system having a Web-related service or agent running on it. The network at the two ends of the connection is any type of network based on TCP / IP protocol (Transmission Control Protocol / Internet Protocol), such as IPv4 or IPv6 protocol.

[0023] More specifically, in the following description, the recording and / or reproducing device is a DVD video player, the remote unit is a ...

Abstract

The present invention relates to a communication system comprising a recording and / or reproducing device (11) able to read a data carrier, and a first remote unit (12) comprising additional data for the data carrier. The recording and / or reproducing device (11) and the first remote unit (12) communicate via a network. The communication system comprises a second remote unit (13) able to authenticate a trusted recording and / or reproducing device, and to make the trusted recording and / or reproducing device access the additional data. A trusted recording and / or reproducing device is able to detect the presence of the data carrier in the recording and / or reproducing device and to authenticate said data carrier.

Description

Field of Invention [0001] The invention relates to a method of communication via a network between a recording and / or reproducing device capable of reading a data carrier and a first remote unit, the first remote unit comprising additional data for the data carrier . [0002] The present invention is particularly relevant to data communication between DVD video players and web sites via the Internet. Background of the Invention [0003] The DVD Forum has established working group AH1-12 to standardize networked DVD as an extension to the current DVD-Video specification. The principle is that a DVD-Video disc conforming to the new specification is linked to a publisher's website for distribution, and the publisher's website contains additional data directly related to the particular DVD-Video disc. For example, the website may include a new navigation menu that can be downloaded and used in place of the original menu by DVD players containing DVD video discs. The communica...
