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. 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 frequencies duplicatively carrying the same service and then higher level PLPs are activated for each duplicate to determine a channel quality metric for identifying the best frequency to receive the service on, which is sent from both stations.

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 receiving signals from plural antennae presents a demanded service while a secondary tuner uses a single antenna to scan for duplicate transmissions of the service, with handing off between the tuners being effected between scanning and service presentation.

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. An ATSC3.0 service list table (SLT) contains correlations between service IDs and frequencies so that a receiver receiving duplicate services on different frequencies in a boundary between broadcast regions can select the best frequency to tune to in order to present the service, without having to access a database to correlate service IDs to frequencies.

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. A receiver, to automatically switch 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, can consider not just signal strength and error rates of two frequencies carrying the same service to select which frequency to tune to, but also relative location and direction of motion of the receiver with respect to each broadcaster.
