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.

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 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 presents a demanded service while a secondary tuner scans for duplicate transmissions of the service and tunes to it if found. When the primary tuner loses signal, it tunes to the frequency of the secondary tuner and acquires any missing NRT data recorded from the secondary tuner prior to the handover.

In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner presents a demanded service while a secondary tuner scans for duplicate transmissions of the service, and if one is found, the version with the better quality metrics may be presented.

In one aspect, a method is performed by a computing system that is in communication with a content-presentation device, where the content-presentation device is scheduled to perform, at a modification start-time, a content-modification operation that comprises modifying a modifiable content-segment that the content-presentation device is scheduled to receive. The method includes determining that the content-presentation device has detected, within a predefined time period after the modification start-time and during performance of the content-modification operation, a mismatch between reference fingerprint data representing the modifiable content-segment and query fingerprint data representing content received by the content-presentation device from a tuner device connected to the content-presentation device. The method also includes determining that the mismatch is due to the tuner device having modified the modifiable content-segment before the modification start-time and, in response to determining that the mismatch is due to the tuner device having modified the modifiable content-segment before the modification start-time, performing an action.

An interactive television program guide system is provided in which a viewer may direct a television to simultaneously display a selected television program and a program guide display. A viewer may use the program guide display to browse available video-on-demand (VOD) while continuing to view a previously selected program in the background. The viewer may browse through video-on-demand programs on the program guide display using a variety of keys on a remote control unit. The viewer may direct the program guide to order a given video-on-demand program/and set a desired broadcast time for that program.

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.

A digital content operating apparatus, including: a communication unit which communicates with an external device which has a display for displaying the digital content; a user operation interface which receives a user operation to control the digital content which is displayed on the external device; a display which displays either a linear content operation panel or an interactive content operation panel; and a controller which controls the user operation interface corresponding to information on the digital content which is displayed on the external device; wherein either the linear content operation panel or the interactive content operation panel is displayed alternatively as the user operation interface on the display.

Techniques for delivering targeted content to a client device (e.g., a set-top-box (STB)) with a tuner, one or more controllers, and a non-transitory memory are described. In accordance with various embodiments, the client device obtains streaming media content in a stream and detects a plurality of transport packets under a packet identifier (PID) in the stream, where the plurality of transport packets is associated with a targeted content delivery service. The client device further identifies metadata corresponding to targeted content of the targeted content delivery service in the plurality transport packets under the PID. The client device then selects a list of targeted content identifiers for the client device based on the metadata and a profile of the client device and downloads the targeted content according to the list of targeted content identifiers.
