摘要： 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 (302) between first and second broadcast stations (304) in which a receiver (300) can pick up signals from both stations, a primary tuner (502) presents (900) a demanded service while a secondary tuner (502) scans (902) for duplicate transmissions of the service, and if one is found, the version with the better quality metrics may be presented.

摘要： 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.

摘要： 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 (302) between first and second broadcast stations (304) in which a receiver (300) can pick up signals from both stations, a lower level signaling PLP is used to identify (604/802) frequencies duplicatively carrying the same service and then higher level PLPs are activated (808) for each duplicate to determine a channel quality metric for identifying (812) the best frequency to receive the service on, which is sent from both stations.

摘要： An electronic device and method are provided for display of signing video through an adjustable user interface (UI) element. The electronic device receives a first media stream that includes a video. The electronic device determines a location of a signer in the video. The electronic device extracts a video portion that corresponds to the determined location in the video. The electronic device controls a playback of the video on the display device. The electronic device controls the display device based on the playback to render the UI element on the display device and display the extracted video portion inside the UI element.

摘要： 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 (302) between first and second broadcast stations (304) in which a receiver (300) can pick up signals from both stations, a primary tuner (502) receiving signals from plural antennae (506) presents (600/804) a demanded service while a secondary tuner (502) uses a single antenna (506) to scan (602/806) for duplicate transmissions of the service, with handing off (820-824) between the tuners being effected between scanning and service presentation.

摘要： 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 (306) to a second frequency (308) such as when a mobile receiver (300) is moving through a boundary region between two broadcasters (304), the current broadcaster application is notified (804/904/1000) and depending on the context, may continue executing (806) or send (906/1004) data to the new broadcaster application.

摘要： 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 (302) between first and second broadcast stations (304) in which a receiver (300) can pick up signals from both stations, a primary tuner (502) presents (600) a demanded service while a secondary tuner (502) scans (602) for duplicate transmissions of the service and tunes to it if found. When the primary tuner loses signal (606), it tunes (608) to the frequency of the secondary tuner and acquires (612) any missing NRT data recorded from the secondary tuner prior to the handover.
