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.
Claims22
In digital television (DTV) system in which at least one receiver can receive broadcast signals, a method, comprising:
- tuning to a primary DTV service broadcast over-the-air (OTA) from a first OTA transmitter;
- presenting the primary DTV service broadcast OTA from the first OTA transmitter;
- based on OTA signal degradation, acquiring a duplicate of the primary DTV service from a wireless transceiver;
- presenting the duplicate of the primary DTV service from the wireless transceiver;
- and
- responsive to acquiring the primary DTV service from a second OTA transmitter, switch from presenting the primary DTV service from the wireless transceiver to presenting the primary DTV service from the second OTA transmitter.
(canceled)
A digital television (DTV) apparatus comprising:
- at least one digital television (DTV) receiver;
- and
- at least one processor programmed with instructions to configure the processor to:
- present a DTV service received from at least a first over-the-air (OTA) DTV transmitter on at least one display;
- upon OTA signal degradation, acquire the DTV service from a wireless transceiver;
- present the DTV service acquired from the transceiver on the display;
- and
- responsive to acquiring the DTV service from a second OTA transmitter, switch from presenting the DTV service acquired from the transceiver to presenting the service acquired from the second OTA transmitter.
(canceled)
A device comprising:
- at least one computer storage that is not a transitory signal and that comprises instructions executable by at least one processor to:
- present a digital television (DTV) service from at least a first over-the-air (OTA) DTV transmitter;
- then switch to presenting the DTV service from a wireless telephony transceiver or satellite transponder;
- and
- as soon as the DTV service is available from a second OTA transmitter, switch to presenting the DTV service from the second OTA transmitter.
