Digital Broadcasting System Mobile Service RS Frame Segmentation

The patent segments the broadcast signal into multiple frames with different structures. Notification frames are inserted periodically between regular service frames, creating a segmented transmission structure that allows robust notification delivery without disrupting the main VSB broadcast service. This segmentation enables the system to maintain standard compatibility while adding resilience to channel changes.

The patent implements preliminary action by pre-configuring notification frames with redundant signaling information and error correction codes before transmission. The notification messages are prepared in advance with multiple copies and checksums, ensuring that even if channel conditions deteriorate, the notification can still be reliably received and processed by mobile devices.

The patent extracts notification functionality into separate, dedicated frames that are distinct from regular service frames. By taking out the notification function and placing it in isolated frames with standardized structures, the system enables targeted processing - receivers can quickly identify and extract notification messages without having to fully decode entire broadcast streams, thereby reducing overall processing complexity.

The patent applies local quality by giving notification frames specialized structures optimized for their specific purpose. These frames contain condensed, standardized notification data with built-in identification fields and error checking, allowing receivers to process only the relevant notification portions efficiently. This localized optimization reduces the complexity burden on the overall system while maintaining high notification delivery capability.
