Abstract
A digital broadcast receiver and a one-touch channel setting method are disclosed. In order to set channels, the digital broadcast receiver tunes a tuner corresponding to an applied channel setting value chosen from available channel setting values that are made from combinations of channel setting value factors by referencing a transponder list corresponding to the applied channel setting value, and sets an antenna and a tuner to correspond with the applied channel setting value in accordance with the tuning result. Thus, the antenna and tuner may be set automatically for searching channels.

A one-touch channel setting method enabling channel setting in a digital broadcast receiver, the method comprising:
- (a) tuning a tuner corresponding to an applied channel setting value chosen from available channel setting values based on combinations of channel setting value factors by referencing a transponder list corresponding to the applied channel setting value;
- and
- (b) setting an antenna and a tuner to correspond with the applied channel setting value in accordance with a tuning result, wherein:
- one or more of the available channel setting values are produced to correspond to channel setting value factors that include satellite information, LNB information, a DiSEqC switch value and a factor indicating whether or not 22 KHz tone is used, and tuner information,
- operation (a) is repeated for a number of all possible combinations of the available channel setting values, and
- the number of all possible combinations is calculated by multiplying a number of satellite information, a number of LNB information, a number of DiSEqC switch values, a number of possible cases on whether or not 22 KHz tone is used, and a number of tuners.
A digital broadcast receiver comprising:
- a tuner unit having one or more tuners and configured to tune a signal inputted from an antenna;
- a controller configured to tune a tuner corresponding to an applied channel setting value chosen from available channel setting values based on combinations of channel setting value factors by referencing a transponder list corresponding to the applied channel setting value, and configured to set an antenna and a tuner to correspond with the applied channel setting value in accordance with a tuning result;
- and
- a channel information storage area configured to store channel information based on a processed signal of a transponder tuned by the tuner, wherein:
- one or more of the available channel setting values are produced to correspond to channel setting value factors that include satellite information, LNB information, a DiSEqC switch value and a factor indicating whether or not 22 KHz tone is used, and tuner information,
- the controller attempts to tune the tuner repeatedly for a number of all possible combinations of the available channel setting values, and
- the number of all possible combinations is calculated by multiplying a number of satellite information, a number of LNB information, a number of DiSEqC switch values, a number of possible cases on whether or not 22 KHz tone is used, and a number of tuners.
