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.

First claim

What is claimed is:

1. In digital television (DTV) 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 at least a first OTA transmitter;
presenting on at least one display the primary DTV service;
scanning for a duplicate of the primary DTV service from at least a second OTA transmitter;
responsive to at least one condition pertaining to the primary DTV service, presenting the duplicate of the primary DTV service;
responsive to at least one condition pertaining to the duplicate of the primary DTV service, acquiring a duplicate of the primary DTV service from a wireless transceiver;
presenting the duplicate of the primary DTV service on the display; and
responsive to acquiring the primary DTV service from an OTA transmitter with a quality satisfying at least one condition, presenting the DTV service from the OTA transmitter with the quality satisfying at least one condition.

2. The method of claim 1 , comprising responsive to acquiring the primary DTV service from an OTA transmitter with a quality satisfying at least one condition, terminating a link between the receiver and the transceiver.

3. The method of claim 1 , wherein the transceiver comprises at least one wireless telephony transceiver.

4. The method of claim 3 , wherein the transceiver comprises at least one 5G base station.

5. The method of claim 1 , wherein the transceiver comprises at least one satellite transponder.

6. The method of claim 1 , wherein the transceiver comprises at least one Wi-Fi transceiver.

7. The method of claim 1 , wherein the at least one condition pertaining to the primary DTV service comprises at least one quality metric.

8. The method of claim 1 , wherein the receiver comprises an advanced television systems committee (ATSC) 3.0 receiver.
