Abstract: A system and method allowing a broadcaster to deliver short-term cyclic data along with the main content of the broadcast stream, synchronized with that main content, and for allowing users to have access to that information for longer periods than a typical data broadcast system would allow. Additional data content is added to the main content stream and is broadcast along with it. The additional data content is initially broadcast shortly prior to the time of its relevance to the main content and is buffered upon reception. In addition, it is rebroadcast cyclically over a short period, allowing viewers who tune in late to take advantage by acquiring the material during and briefly after the time of its initial relevance. If a viewer tunes in after the cyclic broadcast period has elapsed or if there was an error in the receiving or buffering of the additional data content, a return channel can be used to request that the material be retransmitted.

Abstract: A personalized data delivery system for dynamically integrating viewer-specified data with visual content includes an input port for receiving a visual content signal, an output port for displaying enhanced visual content on a display, and an interface operatively coupled to the input and output ports. The personalized data delivery system may also include an input/output port for receiving data from a data content source other than the visual content signal and/or for sending requests for viewer specified data to the data content source. Parameters for the selection and display of data can be customized by the viewer. The interface includes at least one processor responsive to one or more viewer personalization parameters and operative to integrate at least a portion of the received data with the visual content signal in accordance with the personalization parameters.

Abstract: For a network with a distributed hierarchical broadcast architecture, a method for efficiently and reliably distributing data content and remotely managing the storage of content. Both the distribution and the storage management methods are rule-based, utilizing network resources in an efficient manner. Simple and reliable mechanisms are provided for ensuring both data integrity and control over storage utilization. At each stage throughout the network hierarchy, content is distributed to nodes in the subsequent stage based on rules. The rules may be modified at each stage. Only one device in the hierarchy is required to maintain detailed information of the storage characteristics of storage devices and content therein in stages which are subsequent to it in the network. The recipient device owner specifies a set of preferences which may be used for local filtering, or which the owning (or other) entity may use to select data which targets the client's interests.

Abstract: An apparatus is provided for an interactive television commerce environment, acting as a central point of control and information for enabling and facilitating information distribution and transactions in this environment. The apparatus is an essential element of an interactive television (ITV) commerce system, and enables the introduction of interactive commerce services in cable, satellite, and other broadcast networks. Other services provided include interfacing with off-line interactive ads, historical review and tracking services for users, and providing feedback and ITV ad modification capabilities to advertisers. The apparatus, residing at a local head end, can also add to or modify ads by inserting content of local relevance.

Abstract: An interactive TV content creation tool imports video and other assets, including WebPages, Java script, etc., as a series of resources for interactive TV content creation for real time audience estimation and program ratings. A processing system embeds hyperlinks into one or more objects contained in a program frame as desired. Each hotlink has attributes. These attributes include shape, name, description and Z-order. The hotlink can have one of several shapes, including rectangle, ellipse and parallelogram. The hotlink types are included in an object tree which is displayed in a window to a creator. A hotlink type is selected in the hotlink tree, and a window displays a linked properties tab available for the selected object. There are several link types available; linking to a URL, another interactive TV content file, a video clip, an audio clip, an image, or a tracking action and transaction action. There are different parameters for different actions. One parameter is a tracking script.
