Abstract: Recording data for an optical disc such as a DVD has video content data and navigation data. Button data defines one or more user-selectable selection buttons to enable a viewer to select content data when the recording medium is played. Further button data defines at least one phantom button that is not selectable by a viewer because, for example, it is not visually distinguishable, it is hidden within the video data or it is displayed for a short period of time. Although the at least one phantom button is not selectable by a viewer, a copying apparatus parsing the recording data will erroneously identify the phantom button as a user-selectable selection button and will copy data associated with the phantom button. The data associated with the phantom button may adversely affect the copying process or render the copy unplayable or unwatchable.

Abstract: New movies from content providers are often made available on the Internet before being launched in the cinemas. Pre-released movies like DVD Videos for journalists are the main reason for this situation because some journalists seem to make these movies available to the Internet users. However, this causes significant harm to the content providers. According to the invention, the pre-releases are still DVD Videos or other conventional video formats but the playback of such encoded video signal is not possible using only a conventional DVD player or DVD player software because the playback requires additional hardware. An additional box (CP splitter box) splits the original video signal into two different video signals to be projected using two different beamers (A, B) which both are required for generating the whole video content. The beamers have different locations each with a different angle to the silver screen, and each beamer generates only a part of the video.

Abstract: Generally the more effective is the copy protection provided on an optical disc, such as a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the optical disc. It is therefore proposed to include at least one region of subversive data within the content in the data area of an optical disc, and then to prevent access to each such region of subversive data during normal playback of the disc. For a DVD, the subversive data may be incorporated within video objects and/or may be in gaps between files in the DVD_Video zone. It is arranged that there are no navigable paths to the regions of subversive data.

The encryption or authentication may also control access to features or functions of the media module. An authentication module comprising an input/output controller, processor and memory processes an authentication request or command to determine if the media module and camera are compatible. The processor may execute software stored on the memory to perform any type of authentication including a hash operation, symmetric key operation, or asymmetric key operation.

Abstract: A anti-copy programme signal is provided. Copies of the anti-copy video pulses made on a video recorder experience reduced quality and interference in playback making them unpleasant to watch. The uncopied signal can be viewed without any material effect on picture quality. The signal comprises a pulse added to each line of the signal throughout both the visible picture region and throughout the vertical blanking region, as well as a first modulated wave-form added to the vertical synchronization pulses of the signal and a second modulated wave-form added to several lines of the picture signal before the vertical blanking section. The presence of all three of these features together has been found to provide a surprising accumulative effectiveness in causing interference in the reproduction of the modified video signal during playback of the copied video signal, that is greater than the effectiveness provided by the different features taken separately.
