Abstract: ATSC 3.0 IP-based data is broadcast in signed and encrypted messages to one or more ATSC 3.0 receivers that control a barrier such as a gate, usually closed to traffic, in the event of an emergency, such as a fire, to open the barrier to allow additional escape routes or to provide access for emergency vehicles. The ATSC 3.0 system supports a wake-up mechanism which allows a receiver to go to a power saving mode. Periodically the receiver wakes up to check for the wake-up bit. Receipt of an “open” message actuates a battery powered or solar assisted system to open the gate while saving on power consumption. Present techniques can also be used to send messages such as Amber alerts to roads, freeways, and other public signage and to control remote water pumping and sewer pumping stations which currently depend on point-to-point UHF radio links.

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).

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 temporarily use a satellite link or 5G wireless telephony or other over the top (OTT) source to acquire a service until an OTA link satisfies quality requirements.

Abstract: Faster channel change time in ATSC such as ATSC 3.0 is effected by using the native tuner of a display device to present a currently demanded channel and a second tuner, which can be dongle-based, to tune/scan preemptively in the background based upon heuristics such as usage pattern of the user. If the user is pressing channel-up key using a remote control, the second tuner can be scanning and tuning the next channel in the channel map to preemptively tune to a second channel likely to be desired by the user for immediate presentation of that channel through the second tuner.

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.

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 using ATSC 3.0 to augment in-stadium (including in-arena) video feeds. In addition to a central stadium large screen view, spectators can use their mobile devices or view wall-mounted TVs around the stadium to receive in-stadium special feeds broadcast using ATSC 3.0, but not necessarily broadcast beyond the stadium and its environs.

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. 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.

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.
