Abstract: A method and system for providing selective advertising on a television channel is accomplished by downloading appropriate advertisements from an advertising server to a subscriber's set top box over an out-of-band channel. The set top box monitors for events. When an event occurs, the set top box signals the head-end to download ads to the set top box. The ads may be selected using demographic or common channel preference pattern information associated with the set top box.

Abstract: A method and system for providing selective advertising on a television channel is accomplished by downloading appropriate advertisements from an advertising server to a subscriber's set top box over an out-of-band channel. The set top box monitors for download triggers to provide advertisements to the subscriber's set top box and advertising triggers to insert advertisements when an advertising opportunity occurs. The advertisements can be downloaded in advance of any advertising triggers to a local storage means associated with the set top box, if available.

Abstract: Bandwidth loading on the network is managed by pushing e-mail message traffic out to the edges of the network at times when bandwidth demand is low. To accomplish this, a user's e-mail is cached at the proxy server nearest to his presumed location. This decentralizes the e-mail storage away from the mail server and spreads it out over the network at the various proxy servers. This cache action is preferably done when there is a lull in network traffic (e.g., at night). This has the effect of decentralizing the bandwidth demand on the overall network since the e-mail messages have a shorter distance to travel when retrieved by the user from the cache location at the proxy server.

Abstract: A system and method for allowing roaming of a subscriber and password authentication a non-LDAP region. A user signs onto a network access server which in turn connects to the regional LDAP RADIUS server. Password authentication occurs by hashing a transmitted password and comparing it to a clear text password from an LDAP database that has been hashed in the same manner as the transmitted password. When the subscriber is in a non-LDAP region, The password proceeds trough a proxy server to a regional RADIUS server which connects to a non-LDAP server. The non-LDAP server connects to and SMS database and retrieve the clear text password associated with the non-LDFSAP user, hashes it according the same method as the transmitted hashed password and formats the password for comparison in the regional RADIUS server. If the hashed passwords compare, the access is permitted.

Abstract: A system and method for interactively affecting the course of a program or programming content. Viewer purchase electronic tokens which can be used to vote on the sequence of content in a broadcast whether it be audio, video or a combination thereof. Users are periodically polled by a server to vote on the direction that a broadcast is taking. The broadcast is then modified with real-time or stored content based upon the polling results from the viewers. Thus communities of voters have a chance to vote on the direction of content. The invention also allows sub-communities to be formed to pre-vote on a broadcast so that the sub-community can possible vote as a bloc on the direction and content of programming that is presented.
