A method and system for interconnecting .a number of peer to peer networks is disclosed. According to one embodiment, a peer to peer, gateway communicates with one or more peer to peer networks. The gateway communicates with these networks through the Internet, to which it is connected. The gateway may be configured to perform a number of functions on each of the connected networks, including but not limited to: data storage, searching, data transfer, and data translation.

Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on an illegal copy. The enhancements in one version introduce into the overscan portion of the television picture, just prior to the horizontal or vertical sync signals but in active video, a negative going waveform that appears to the television receiver or videotape recorder to be a sync signal, thereby causing an early horizontal or vertical retrace. One version provides (in the right overscan portion of the picture), a checker pattern of alternating gray and black areas which causes the TV set on which the illegal copy is played to horizontally retrace earlier than normal in selected lines with a consequential horizontal shift of the picture information on those lines. This substantially degrades picture viewability. In another version a gray pattern at the bottom overscan portion of the picture causes vertical picture instability. In another version selected horizontal sync signals are narrowed, causing irregular vertical retraces. Also provided is apparatus for removing or attenuating these enhancements from the video signal, to allow copying.

To copy protect an optical disc, such as a DVD, program chains additional to the main program chain are provided. These program chains may lead to the genuine data but in an incomplete or incorrect order or to false data. Sufficient additional program chains are provided to make it difficult to identify the main program chain amongst all of the program chains provided on the disc. The structure of the further program chains ape that of the main program, again to hide the main program chain. The navigation path which leads to the main program chain, and hence to the content on the DVD, is dynamically generated and at least some of the information required to generate the navigational path arises by setting parameters associated with a player or with a user. Thus a search of all of the navigation information on the disc will fail to reveal the navigation path to the content.

According to one embodiment, a method is described. The method includes receiving a request at a control module from a first remote device to access media data from a storage management module and determining that a first user is requesting access to the data based upon a first remote identification (ID). The method further includes opening a second stream between the playback module and the storage management module and receiving the data at the playback module.

Playability of a copy protected video signal is improved by reducing the darkening and or venetian blind effects which tend to cause artifacts in a video signal display. To this end, the copy protection signal includes automatic gain control (AGC) signals or pulses in video lines in a portion of the active or viewable video field or frame, wherein the AGC pulses comprise non similar AGC signals from one video line to another video line. The dis-similar AGC pulses may include pulses which are deleted, blanked, attenuated, pulse width modified, modulated, etc. In addition, selected sync pulses may be pulse width, amplitude and or position modified.

A method and system for tracking and optimizing advertisements on a decentralized network. In one embodiment, the method comprises receiving a request for a user from a user on a network. The method further comprises responding to the request by transmitting the file to the user, the file containing an identifier. The identifier is used to track the user's treatment of the file.
摘要:
A method and system for collecting data to support a software application are disclosed. In one embodiment, the method comprises receiving as an input a software application. Installation data is retrieved from the software application. The method further comprises encoding within the installation data a description of support data to be collected from a user of the software application.
摘要:
Apparatus and a method are described to enable reading apparatus to access content data of an optical disc such as a DVD where the content data carried by the DVD is encrypted by an encryption technique that requires a decryption key or keys. Reproduced content data corresponding to the encrypted content data is provided and this reproduced content data, at least some of which may be encrypted using a different technique, is made available for access by a reading apparatus. The reproduced content data may be stored on the same optical disc as the encrypted content data or at a different location, for example on a storage medium which may be coupled to the reading apparatus or at a location on a network that can be accessed by the reading apparatus.
摘要:
A custom media production system and methods have been disclosed. A method comprises generating custom media based on a customer order and other factors, wherein generating includes choosing media, format, or both based on selection information.
摘要:
The method and apparatus described utilise the fact that CDs manufactured from the same master will have distinctive physical characteristics attributable to the physical manufacturing process of the master to distinguish counterfeit CDs from genuine discs. For a genuine disc, the relative angular orientation of specified sections of the recorded data are determined and recorded. The relative angular orientation of the same sections of data on a test disc are also determined. Where the relative angular orientations are the same it is concluded that the test disc derives from the same source as the genuine disc and is therefore bona fide. Where there is no correlation, the test disc may be identified as counterfeit. The relative angular orientations, or other physical characteristics of the discs, may be physically measured, or may be calculated from information gained by reading the data on the disc. The disclosed technique can also be used to copy protect discs.
