    摘要： A system and method implemented in an interactive television system for restricting or controlling the access rights of interactive television applications and carousels. The system broadcasts modules from a broadcast station to a plurality of receiving stations, which execute applications containing the modules. In one embodiment, the applications utilize a credential consisting of a producer identification number (ID) and an application ID for each of the grantor and grantee applications, an expiration date, a set of permission data, a producer certificate and a signature. An application requesting access and a carousel granting access may be identified by respective producer and application IDs. The credential utilizes public key encryption to ensure the integrity of the credential. The producer and application IDs may be replaced with wildcards so that rights may be granted to a group of producers or applications.

    摘要： A generic data processing engine is operable to receive a format definition and process data formatted according to the definition, without use of formatting information in the data. The format definition includes a description of the syntax of the format, and a description of the semantics of the format. The syntax and semantics may be described in the same language or in different languages, and the engine is configured to produce an internal representation of the syntax and semantics. The engine receives queries and uses them together with the internal representation to set masks for the filters. The filters apply the masks to the data and return filtered data to the engine, which may forward a portion of the filtered data to applications, store a portion of the filtered data, set new masks based on a portion of the filtered data, or modify the existing masks based on a portion of the filtered data. The filters may also be configured to return filtered data directly to applications, bypassing the engine.

    摘要： A method and mechanism for selecting and conveying ads in an interactive television system. An ad stream is conveyed concurrently with a broadcast programming stream in an interactive television system. The ad stream includes multiple streams of ads wherein each stream of ads includes multiple ads. An ad selector mechanism detects programming and ad requests. Requests may be indicated by a viewer, a received cue, or by an interactive application. Based on programming and ad selection data, a viewer profile is created which may be used to select targeted ads for display. In response to a detected request, the ad selector mechanism searches the ad stream for an ad to meet the request. An ad is selected according to a viewer profile or a particular viewer action. The selected ad may be used to meet the request by filling an unused avail or by providing further information to a viewer. A particular ad may appear in more than one of the multiple streams and at different start times. Additionally, a particular ad may appear multiple times in a single stream. The multiple appearances of a particular ad offers multiple possible start times for the ad.

    摘要： A method and apparatus is described to reduce delay when changing channels in a television environment. The method may comprise receiving a plurality of television channels from a remote content provider wherein each channel includes channel information used to display the channel. At least one channel of the plurality of channels may be identified as a stored channel and channel information of the at least one stored channel may be stored in storage (e.g. in a circular buffer). Thereafter, upon selection of the stored channel, the stored channel information is accessed for display. In an example embodiment, the storage may be updated to maintain a most recently received I-frame and subsequent MPEG signals of the stored channel. Accordingly, when changing channels it may not be necessary to wait for the next I-frame to display a newly selected channel.

    摘要： A method for recording pushed interactive data streams of a program. A pushed data stream is broadcast to a receiving station. The data stream includes one or more data objects. The data stream may also reference to live data objects which are intended for immediate consumption and become obsolete thereafter. The data stream may include a file table and object properties corresponding to the data objects. When the data stream is received by the receiving station, the individual data objects are extracted from the data stream. The data objects, accompanying object properties and the file table are then stored on a storage device. Data objects which are external to the data stream or to the program (e.g., data objects from other carousels) are retrieved and are also stored. Live data objects are not stored, but references to these data objects are stored, so that when the program is replayed, current versions of the referenced live data objects can be used. A program not being recorded may contain data objects which are flagged to be cached which are recorded automatically. Consequently, other programs may subsequently access them from the recording when they are played.
