  • Publication number: 20050276257
    Abstract: A method and system for efficiently delivering messages from a service provider to individual receiving devices in a unidirectional, multi-channel communications system that provides parallel distribution of information from the service provider to the receiving devices. The messages are transferred from the service provider to the receiving device only on an agreed-upon channel at an agreed-upon time, wherein each message is tagged with an address corresponding to the receiving device by the service provider and then transmitted by the service provider to the receiving device on the agreed-upon channel with the receiving device filtering the agreed-upon channel to detect the address and decode its messages. The agreed-upon channel and the agreed-upon time of message transfers are coordinated between the service provider and the receiving device prior to transferring the message from the service provider to the receiving device.

  • Publication number: 20050235330
    Abstract: Quasi on-demand programming is dynamically scheduled in a broadcast television network to improve customer service, enhance programming flexibility and increase the value proposition of the service provider. A Program Offer including a “delivery window” for each program and an initial Playlist for broadcasting regular, PPV and offered programming are created. Customer demand for individual programs in the offering is surveyed. This information is used to reoptimize the Playlist prior to broadcast and to update a “rolling” Program Offer to better manage network capacity and improve custom satisfaction.
