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. 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.

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. To improve robustness for datacast files, a checksum is provided for each source block in the file, allowing the receiver to discard only a portion of the data as defined by the length of a corrupted block in the AL-FEC parameters. A list of checksums for each source block can be included in the RepairFlow element of the service transport session instance description (S-TSID) since RepairFlow element and AL-FEC provide the breakdown of the data into source blocks.

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: 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 along with parameters of the RF environment as previously measured by an autonomous vehicle such as a drone.

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.

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 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.
