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 uses relative location and direction of motion of the receiver with respect to each broadcaster to determine which tuner/demodulator(s) to use to present a service and which to use to scan for services.
Claims20
In digital television in which at least one receiver can receive broadcast signals from at least first and second digital television broadcast transmitters, a method, comprising:
- identifying respective locations of the transmitters;
- identifying a location of the receiver and at least one parameter of motion of the receiver;
- based at least in part on the respective locations of the transmitters, the location of the receiver, and the parameter of motion of the receiver, identifying at least a first tuner of a multi-tuner chip to provide signals to a primary demodulator or decoder;
- using an output of the primary demodulator or decoder to present a demanded service on at least one display;
- and
- based at least in part on the respective locations of the transmitters, the location of the receiver, and the parameter of motion of the receiver, identifying at least a second tuner of the multi-tuner chip to scan for a duplicate of the demanded service.
An apparatus comprising:
- at least one receiver configured to:
- identify respective locations of first and second transmitters;
- identify a location of the receiver and at least one parameter of motion of the receiver;
- based at least in part on the respective locations of the transmitters, the location of the receiver, and the parameter of motion of the receiver, identify at least a first tuner to provide signals to a primary demodulator or decoder;
- use an output of the primary demodulator or decoder to present a demanded service on at least one display;
- and
- based at least in part on the respective locations of the transmitters, the location of the receiver, and the parameter of motion of the receiver, identify at least a second tuner to scan for a duplicate of the demanded service.
A digital television apparatus comprising:
- at least one receiver comprising at least one processor programmed with instructions to configure the processor to:
- identify respective locations of first and second signal sources;
- identify a location of the receiver and at least one parameter of motion of the receiver;
- based at least in part on the respective locations of the signal sources, the location of the receiver, and the parameter of motion of the receiver, identify at least a first tuner to provide signals to a primary demodulator or decoder;
- use an output of the primary demodulator or decoder to present a demanded service on at least one display;
- and
- based at least in part on the respective locations of the signal sources, the location of the receiver, and the parameter of motion of the receiver, identify at least a second tuner to scan for a duplicate of the demanded service.
