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. Signaling indicates where the first few segments of a changed-to broadcast service can be obtained on the broadband network. Segments not including the live edge segments are downloaded and played immediately to reduce perceived latency in the service change until the broadcast segments arrive for 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. 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.

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 empty x-link period is provided at the end of an MPD to alert a newly tuning in receiver to obtain and insert a replacement ad in the period.

Abstract: A TV without a touch screen can nonetheless execute applications designed for mobile devices that assume a touch screen user interface (UI) by a “dumb” remote control with up/down, left/right, select buttons, or by a remote control with a touch pad, or by a remote control application running on a mobile device with a touch-screen that communicates with the TV. In all three scenarios, the TV recognizes that it is running in a special remote control mode and with a corresponding remote control application running on the TV that is able to intercept key presses and finger swipes and translate them to touch screen commands that are input to a touch screen-enabled software application running on the TV.

The processing circuitry executes a television receiver application that displays the television content. The processing circuitry receives indication of a selection of a key that is provided on an input device.

Abstract: A method for managing a buffer having a preset byte size for storing files includes determining a file identifier and length of an incoming file. The method includes determining that the incoming file will not fit into a space between a next write location and an end of the buffer. In response to the determination that the incoming file will not fit, the method includes, in a map, deleting each entry corresponding to a file at least partially overlapping the range of the incoming file and adding an entry in the map for the incoming file. The method further includes allocating a contiguous area in the buffer for the incoming file and then moving the next write location to the end of the allocated contiguous area, and receiving packets of the incoming file and storing the received packets into the allocated contiguous area.
