Blackout Retune Distribution via Local Multiplexing and Requantization

The patent segments the distribution network into wide area operation infrastructure (WOI) and local area operation infrastructure (LOI). The WOI maintains the wide area feed with blackout events, while the LOI receives and processes this feed to create local retune services. This segmentation allows retune events to be implemented locally without disrupting the wide area SFN, as each LOI independently manages its own retune feed while adjacent LOIs continue broadcasting identical wide area signals.

The patent applies local quality by making retune events location-specific rather than universal. Each LOI can independently enable or disable retune events based on local contractual obligations, while the WOI maintains a consistent wide area feed. This allows different geographical areas to have different programming arrangements without interfering with each other, as the retune feed is generated and distributed locally to each LOI.

The patent implements a universal retune feed that can serve multiple LOIs simultaneously. The WOI generates a single retune feed that contains alternate programming for blacked out events, and this feed is distributed to multiple LOIs that need retune capability. This multi-functional approach allows the same retune infrastructure to serve numerous local areas, reducing overall system complexity compared to implementing separate retune systems in each LOI.

The patent introduces the WOI as an intermediary between the content sources and the LOIs. The WOI receives wide area feeds, processes blackout events, generates retune feeds, and distributes them to LOIs. This intermediary layer simplifies the architecture by centralizing the complex retune generation logic in the WOI, allowing LOIs to simply receive and broadcast the provided feeds without implementing complex retune control systems themselves.

The patent merges the retune functionality into the existing satellite receiver infrastructure. Instead of deploying separate per-retune feed satellite receivers, the system uses the standard satellite receivers already present in each LOI to receive both the wide area feed and the retune feed. The receiver simply tunes to different feeds based on local control signals, eliminating the need for additional dedicated hardware and reducing capital expenses.

The patent creates a retune feed that is a copy or alternative version of the wide area feed, specifically designed for blackout situations. The WOI generates this retune feed by copying the structure and format of the wide area feed but populating it with alternate programming content. This approach allows existing receivers to process the retune feed without modification, avoiding the need for expensive specialized hardware while maintaining full retune functionality.
