Abstract: Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol. In an ATSC 3.0 environment, receivers (including consumer and professional receivers) have signal reception parameters and antenna factors available to them. These reception parameters, together with time and location data are transmitted to one or more servers that maintain databases of reception characteristics. This data is analyzed such that a set of likely receivable signals (based on reception parameters, date/time, location, geographical features, transmitter information, etc.) is identified. Receivers query the servers to receive information indicating the set of likely receivable signals to reduce channel scan time by scanning only or first for more-receivable channels. Also, difficult reception locations identified in the data collected by the servers are used in aggregate to guide RF improvements (e.g., adding SFN transmitters). Further, the data collected by the servers may provide data to be used to feed “MFN” data.

Abstract: Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Multiple memory buffers are used to manage broadcast packet repair and presentation or storage.

Abstract: Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. When automatically switching from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, the current broadcaster application is notified and depending on the context, may continue executing or send data to the new broadcaster application.

Abstract: Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner presents a demanded service while a secondary tuner scans for duplicate transmissions of the service and tunes to it if found. When the primary tuner loses signal, it tunes to the frequency of the secondary tuner and acquires any missing NRT data recorded from the secondary tuner prior to the handover.

Abstract: Techniques are described for concealing aspects of RC in the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In this way, by delivering information needed to play the RC very shortly before insertion is to occur, skipping strategies can be foiled.

Abstract: Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a lower level signaling PLP is used to identify a channel quality metric for identifying the best frequency to receive a broadcast service on which is sent from both stations.
