Abstract: Systems, management and distribution methodologies (including both hardware and software components) for the delivery of subscriber-specific TV and multimedia broadcasts. The system delivers multimedia files, regardless of compression or format, to subscribers; instead of normal linear broadcasts or content streaming. Delayed Negative Acknowledgment allows the client application to request any missing packets via a low speed return path to the TV Aggregation Servers. These negative acknowledgments are aggregated over a long delay period based on the initial broadcasts' time to live. Once a considerable threshold has been reached the missing content is rebroadcast, clients receive any missing packets and mark the initial broadcast as complete thus making it available for viewing.
