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.

ATSC boundary condition fall over to internet

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. To improve robustness for datacast files to limited memory platforms, each file is divided into partitions and then the packets in a partition are arranged out of order (OOO), with the partitions then being sent in order with their respective packets OOO.

Method for signaling memory requirements in ATSC3.0 when out-of-order data is being utilized

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.

Digital TV reception using OTT backchannel communication

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 ATSC 3.0 receiver backs off the live point of a broadcast by a short delay period such that channel change may be rendered perceptibly faster by pre-fetching segments identified in a SegmentTemplate MPD from broadband before the broadcast channel is fully tuned to.

Reducing latency during service change and improving robustness in advanced television systems committee (ATSC) 3.0 system

Techniques are described for using the Advanced Television Systems Committee (ATSC) 3.0 television protocol and more specifically various types of ATSC 3.0 signaling to deliver private content for signage to kiosks and other public displays.

Digital signage using ATSC 3.0

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 uses relative location and direction of motion of the receiver with respect to each broadcaster to determine which tuner/demodulator(s) to use to present a service and which to use to scan for services.

Dynamic antenna configuration

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.

Obfuscating replaceable content in advanced television systems committee (ATSC) 3.0 system

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.

Techniques for ATSC 3.0 broadcast boundary area management using signal quality and packet errors to differentiate between duplicated services on different frequencies during scan

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.

Techniques for ATSC 3.0 broadcast boundary area management using complete service reception during scan to determine signal quality of frequencies carrying the duplicate service

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. Telepresence is provided through over-the-air (OTA) virtual reality (VR) broadcast streams.

Telepresence through OTA VR broadcast streams

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.

Stream repair memory management

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.

Techniques for ATSC 3.0 broadcast boundary area management using plural tuners handing off between presentation and scanning

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.

ATSC 3 application context switching and sharing

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.
