摘要:
An apparatus (270) and method is disclosed for preventing a viewer from switching from a channel when an advertisement is being displayed on the channel. The apparatus (270) and method comprises an advertisement controller (270) in a video playback device (150) that (1) prevents a viewer of a direct (non-recorded) broadcast from switching channels when an advertisement is displayed, and (2) prevents a viewer of a recorded program from fast forwarding the recorded program in order to skip past advertisements that were recorded with the program. A viewer may either watch the advertisements or pay a fee in order to be able to change channels or fast forward when the advertisements are being displayed.

A method (1) of transmitting interactive television, whereby interactive television applications are transmitted inside application-modules. These modules are transmitted in a broadcast stream. Recording systems cannot decide which modules are to be recorded. Therefore storage related information of said modules is signalled in the broadcast stream. Module identification information related is implemented in the Application Information Table (AIT) and/or in the Download Information Indication (DII) message. Thus information is included in the broadcast stream concerning categories stating whether application modules are mandatory, optional or forbidden to record. Alternatively properties of a module are chosen from Code/Data/Both and/or Fixed/Variable. Recording systems use this information do decide if application modules are to be recorded or disregarded. Alternatively, application module identification information is transmitted in said broadcast stream. A module identification number is used to avoid multiple recordings. Application modules having the same category are preferably grouped together.

The present invention relates to a method of recovering blocks of data recorded on an optical record carrier in case of a power failure affecting a recording and reproducing device. Said device comprises means for writing a recording indication information on the optical record carrier to indicate that a recording has started, said recording indication information including a recording start address, and means for overwriting the recording indication information at a recording end. After a power failure, if a recording indication information is written on the optical record carrier, then the recording and reproducing device is able to determine that a recording has not ended properly. In these conditions, said device is able to parse the recorded data, starting from the recording start address, in order to find the end of the improperly ended recording.
摘要:
A first content is received and presented to a user on a television (TV) platform (16). A second content is also received and presented concurrently to the user. In an interactive TV platform (16), a user selects the second content. In one aspect, the first content is advertising content (40) and the second content is information content (46), electronic mail content (42), downloadable file content (44), or program content (32, 34, 36, 38). In another aspect, the first content is program content (32, 34, 36, 38) and the second content is one of information content (46), electronic mail content (42), advertising content (40), and downloadable file content (44).

A transmission system includes at least one receiver 60 and a transmitter 10, 20, 30 for transmitting a title to the receiver. The transmitter also transmits interactive features that enable a user to interact with the title. Thee features interact with the title through a DVD virtual machine. The receiver 60 receives the transmitted title and transmitted interactive features. A controller 250 of the receiver 60 implements the DVD virtual machine to enable execution of the received features in the receiver.

There is provided a communication network (10) operable to search for programme content. The network (10) is distinguished in that it comprises: (a) a plurality of mutually interconnected network nodes (100, 110) susceptible to storing programme data content and at least one of electronic programme guides (EPG) and associated meta-data thereat; (b) at least one user-operable node (20) coupled to the network (10), the at least one user-operable node (20) including user-interfacing means (30, 50) for receiving instructions from a user (60) and presenting results to the user (60). The network (10) is arranged such that: (c) the plurality of network nodes (100) and/or the at least one user-operable node (20) are operable to access electronic programme guide (EPG) data and/or associated metadata providing a record of at least previous programme data content communicated within the network (10); (d) the network (10) is operable to present one or more electronic programme guides (EPG) to the user (60) for generating therefrom a search request susceptible to utilizing meta-data associated with the one or more electronic programme guides (EPG) for use in identifying corresponding data content available in the network (10); and (e) the at least one user-operable node (20) is operable to receive data content thereat corresponding to the search request.

The invention relates to a content item recorder (101) comprising storage means (109) for storing a plurality of content items. The content item recorder (101) may be a Personal Video Recorder comprising a hard disk. The content item recorder (109) comprises a back-up processor (115) generating reduced reference information associated with the plurality of content items; and a memory interface (117) for storing the reduced reference information to a back-up memory (119) separate from the storage means (109). The reduced reference information may be reduced user profile information of reference information allowing external copies of content items to be identified from external sources which may specifically be part of a peer-to-peer network. The reduced reference information may automatically be stored on recordable DVD disks when a content item is stored thereon. Following a hard disk malfunction or replacement, hard disk information may be restored in response to the reduced reference information.
摘要:
A method (49, 55) of handling fonts in a recorder or a playback-recorder for interactive television. Fonts are stored on a recordable storage medium (220), wherein the fonts are part of a downloaded interactive television application. When recording, the downloaded fonts are stored separate from the application, preferably in a font library on the recordable storage medium, which preferably is a removable medium, preferably an optical storage medium. Each font is only stored in one copy, even when a plurality of applications on the storage medium need that font for running. When playing back the application from the storage medium, indicating information is provided on which fonts form the storage medium in the font library are required for playback of said application from said storage medium. Thus multiple storage of fonts is prevented, minimising needed storage space on the storage medium.

Portable devices for rendering multimedia data objects are widely known; mainly for reproducing audio, but also for reproducing video. These devices are powered by battery, which is known to have a limited amount of energy available. This carries the risk that no energy is available any more, while a multimedia data object that is rendered, is not rendered in full this leaves a user unsatisfied. Therefore, the amount of energy of the battery is checked and when a multimedia data object selected to be rendered can be rendered in full, it is rendered. When it cannot be rendered in full, it is not rendered. In an embodiment according to the invention, this check is made for a group of selected multimedia data objects.
