An entertainment head-end provides broadcast programming, video-on-demand services, and HTML-based interactive programming through a distribution network to client terminals in subscribers' homes. A number of different features are provided, including novel user interfaces, enhanced video-on-demand controls, a variety of interactive services (personalized news, jukebox, games, celebrity chat), and techniques that combine to provide user experiences evocative of conventional television.

Systems and methods for selecting and inserting advertisements in an information document displayed to a user, wherein the selection is based at least in part on television programming viewed by the user. The systems and methods may be implemented using the Internet or another information retrieval system that includes a client system and a remote server. The client system monitors television programming viewed by the user and compiles a user profile characterizing the television programming. When the user requests an Internet resource using the client system, the television programming information in the user profile is utilized to select an appropriate advertisement. The advertisement is then inserted in the information document and displayed to the user. Advertisement selection and insertion may be conducted at the remote server, the client system, or at the level of the Internet service provider. Such selection of advertisement increases the efficiency by which Internet advertisements are tailored to individuals. Instead of advertisements, information relating to the television programming may be retrieved over the Internet and displayed without direct user assistance.

A recipient computer system may receive one or more electronic messages. The recipient computer system may send one, two, or more challenge messages to the sender of the electronic messages in determining whether to deliver the electronic message. The recipient computer system may accept or reject an electronic message based on the response, or lack of response, to the challenge messages. The recipient computer system may send two or more challenge messages at intervals. A sender computer system may record activity of the sender computer system for a recipient computer system to use in determining whether to deliver an electronic message. A sender computer system may provide a summary of that activity with an electronic message. A sender computer system may provide an authorization key for a recipient computer system to use in determining whether to deliver an electronic message. The authorization key may be generated by a third party.

Systems and methods for sorting electronic messages using attributes of senders or of sender addresses. An electronic messaging server sorts electronic messages using attributes associated with the senders or sender addresses of the electronic messages. The sender addresses and associated attributes are stored in an accept list. A sorting module uses the accept list to sort the electronic messages into various folders. The sorting module can also access other data sources, such as a contact list, to assist in sorting the electronic messages. The attributes can be determined independently of the user or can be set directly by the user. The attributes can also identify a status of a sender such as whether the sender is authorized, unauthorized, or unconfirmed.

A video on demand system includes a head-end coupled through a proxy server to plural client terminals. The proxy server performs (or cooperates with another component in performing) various functions, including user interface definition, security, system administration (e.g. channel management, load distribution, and failover), and protocol translation.

摘要:
Systems and methods for allowing challenge messages to be sent directly to a recipient's inbox where normally the challenge message would be sent to a pending folder or deleted. Challenge messages sent between federated messaging services contain a federated token which can be identified, authenticated and validated to determine whether the challenge message should be sent to a recipient's inbox. The federated token can include an authentication portion and a validation portion. Authentication methods for the authentication portion can include, for example, checksums, salts, hashes and digital signatures. Once a federated token is authenticated by decrypting the authentication portion according to one or more of these authentication methods, the federated token is validated by determining the defined use-base and determining whether the receipt of the federated token satisfies the defined use.
摘要:
A server system provides a client system with access to a number of services. For each service, if a given service provider is overloaded or if the client is unable to contact that provider, the client can contact another service provider capable of providing the requested service. The server system provides information to the client system identifying a list of services that the server system provides. For each service in the list of services, the information may include a service name identifying the service, and a unique port identifying each service provider for that service, so that one service name can be used in accessing multiple service providers of a desired service. A request from the client may include a service name identifying the desired service, and a port selected from ports provided by the server system that corresponds to a service provider for the desired service.
