Abstract: Systems and methods to modify playout or playback include a first and second approach to respond to a trick mode request (e.g., fast forward, rewind). First, a trick mode request may be responded to by associating primary content to secondary content and playing out the secondary content on a receiving device, the secondary content not being derived from the primary content. Second, a trick mode request may be responded to by associating primary content to secondary content and playing out the secondary content on a receiving device, the secondary content being derived from the primary content but played at a normal speed for the secondary content.

Abstract: A method for transmitting data. Data received from a data source is retained in a buffer. Initial data may be provided from the buffer. Additional data may be provided from the buffer.

Abstract: A system for integrating video programming with the vast information resources of the Internet. A computer-based system receives a video program with embedded uniform resource locators (URLs). The URLs, the effective addresses of locations or Web sites on the Internet, are interpreted by the system and direct the system to the Web site locations to retrieve related Web pages. Upon receipt of the Web pages by the system, the Web pages are synchronized to the video content for display. The video program signal can be displayed in a video window on a conventional personal computer screen. The actual retrieved Web pages are time stamped to also be displayed, on another portion of the display screen, when predetermined related video content is displayed in the video window. As an alternative, the computer-based system receives the URLs directly through an Internet connection, at times specified by TV broadcasters in advance. The system interprets the URLs and retrieves the appropriate Web pages.

Abstract: The present invention relates to a simplified electronic message response, such as an electronic mail (e-mail) response. According to an embodiment of the present invention, a sender may send an electronic message, such as an e-mail, that includes a main message and one or more options. The receiver may select any of the options, for example, by pressing a number on a remote control that corresponds to an option. Once an option has been selected, information related to the selected option, such as text explaining the selected option to the user, may be presented. The user can then indicate a desire to transmit the selected option. A reply e-mail is automatically generated and sent to the original sender, such as the advertiser.

Abstract: According to an embodiment of the present invention, a fast matching algorithm uses a memory space efficient data structure to accomplish information filtering in a system receiving information, such as a set top box used in conjunction with a television set. The data structure, according to an embodiment of the present invention, may include a node with a plurality of levels of expected values of data fields with an associated index to another node to be used when a matching identification of a particular level is not found. Additionally, according to an embodiment of the present invention, the nodes in this data structure may include a level field which identifies levels which are valid within the node.

Abstract: A chat room is broadcast in an interactive television environment for lurking “in” a chat room, without the need for establishing a back channel connection. The present invention provides a mode of chat room broadcasting and communication that can be easily handled by a client device, typically a set top box (STB) processor, an interactive television server and its subscriber clients. The present invention broadcasts chat rooms to clients who may either connect through a back channel to participate in a chat room or simply lurk, that is, to watch the chat room content and discussion in the broadcast without participating or registering in the chat room.

Abstract: The present invention provides a method and apparatus for managing the presentation and regulation of E-Commerce, content and service providers access in an interactive television environment comprising interactions between a server, a client, and a service provider. Components are provided for managing and completing a purchase or delivery of an item offered by a service provider. A purchase transaction uses client information comprising partial client information from the client and a list of purchased items. Upon receiving partial information from the client, the server retrieves corresponding additional related information within its database and transmits this retrieved data from the server, along with the list of purchased items to complete the transaction. Business Agents are provided for logging the transaction, creating an electronic receipt, logging patches, logging error events, and viewer logging.

Abstract: A method and apparatus for extracting and compiling an interpretative language to implement functions such as those written as a script embedded in a HTML page in an interactive television environment. HTML pages are are received from both broadcast and online. The compiler runs on a server. The compiled scripts run faster and require less processing power to execute. The compiler runs on a server. The scripts are extracted from HTML representing content stored at the server. The compiled script code is then transmitted from the server to a client device, through broadcast or online, for execution during content display at the client device. The compiled scripts run faster, require less processing power to execute, and run on client devices that do not have the interpreter for that language.
