    摘要: A method and apparatus is disclosed which reduces or removes the effectiveness of commercial skip systems such as presently found in VCRs, PVRs, etc. which are designed to delete commercials from signal material upon playback of a previously recorded version of the signal material. In an embodiment, the effectiveness of the commercial skip system is reduced or removed by adding a flat field of selected signal level to active line portions of video lines of the signal material. Other embodiments modify the normal fade to black signal indicative of a commercial to provide a fade to non-black signal. In further embodiments, a fade to non-black signal is inserted in an overseas area of the signal picture. Still further embodiments modify audio signals or selected signals in the horizontal blanking interval which may be used in commercial skip systems to detect the presence of commercials.

Other embodiments modify the normal fade to black signal indicative of a commercial to provide a fade to non-black signal. In further embodiments, a fade to non-black signal is inserted in an overscan area of the signal picture. Still further embodiments modify audio signals or selected signals in the horizontal blanking interval which may be used in commercial skip systems to detect the presence of commercials.

    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 computer-implemented system and method for embedding and authenticating ancillary information in digitally signed content are disclosed. The method and system include: loading digital content containing a digitally signed portion into memory for processing; identifying an existing digital signature block and an existing digital signature size block in a digitally signed file header of the digitally signed portion; obtaining a digital signature size value from the digital signature size block, the digital signature size value corresponding to the size of the digital signature block plus the length of an ancillary data block plus a pre-determined pad; authenticating the integrity of the digitally signed portion using the digital signature while processing the digital content; unwrapping a purchase mechanism built into as wrapper associated with the digital content; and extracting from the ancillary data block data referenced by instructions of the purchase mechanism, the extracting being performed without invalidating the digital signature.

    摘要: A user interface is implemented on a client device remote from a host device. The host device operates an application program that implements a user interface, such as an electronic programming guide or a guide for a personal video recorder, that permits a user to control at least one target device. The host device transfers to the client device an identification of at least one scene. In general, a scene defines an abstract layout for at least one screen display of the user interface. The client device generates at least one screen display for the scene based on its interpretation of the scene. The client device then displays the screen as an implementation of the user interface. Thereafter, a user initiates, using the client device, an operation to control the target device. In response, the target device performs the operation. The host device may also display information at a client device For example, the host device may transmit information about a media currently playing at the client device.
