US 2022/0150440 A1 · METHOD FOR SCANNING TELEVISION CHANNELS AND TELEVISION SYSTEM

Abstract

A method for scanning television channels and a television system are provided. The television system includes a circuit system, a storage unit, and a control circuit. The circuit system is used to receive and demodulate television streaming data, separate information in the television streaming data, and decompress and convert the television streaming data into video and audio. The method is performed in the control circuit. In the method, a channel-selection transceiver circuit receives a channel-selection signal. After channel data stored in the storage unit is analyzed, it is determined whether the channel-selection signal corresponds to any television channel in the channel data. If the channel data does not include the television channel corresponding to the channel-selection signal, a scanning routine is performed in a background for scanning the television channels. A scanning result is then generated and used to update the channel data in the storage unit.

Dependent claims

A method for scanning television channels, which is adapted to a television apparatus, the method comprising:

receiving a channel-selection signal that corresponds to a television channel;
analyzing channel data stored in the television apparatus, so as to determine whether or not the channel data includes the television channel;
and
performing a scanning routine in a background if the channel data does not include the television channel corresponding to the channel-selection signal to scan the television channel failing to correspond to the channel-selection signal and generate a scanning result;
then, updating the channel data stored in the television apparatus.

2 more elements

A television system, comprising:

a circuit system used to receive television streaming data, demodulate the television streaming data, separate information in the television streaming data, and decompress and convert the television streaming data to video and audio;
a storage unit having a channel database;
and
a control circuit electrically connected to circuit elements of the circuit system, wherein a method for scanning television channels includes:
receiving, by a channel-selection transceiver circuit, a channel-selection signal that corresponds to a television channel;
analyzing channel data stored in the storage unit, so as to determine whether or not the channel data includes the television channel;
and
performing a scanning routine in a background if the channel data does not include the television channel corresponding to the channel-selection signal to scan the television channel failing to correspond to the channel-selection signal and generate a scanning result;
then, updating the channel data stored in the storage unit.
