Abstract
In a digital broadcast reception apparatus, a presetting operation is carried out and, when the presetting operation is carried out, a normal reception of a broadcast signal on a channel, which can be received in an area in which the apparatus is installed, and the normal reception of which cannot be found in the event that a gain in a gain switching amplifier is of an initial value, is made possible by a switching and setting of a gain in each VGA 3, 5a and 5b being carried out by means of a control circuit 9 or an operating unit 11.
Claims7
A digital broadcast reception apparatus comprising:
- an antenna through which is received a broadcast signal of a digital broadcast;
- a gain switching amplifier which, as well as attenuating or amplifying the broadcast signal received through the antenna, can switch a gain;
- a demodulator circuit which demodulates the broadcast signal, attenuated or amplified by the gain switching amplifier, by means of a digital modulation method;
- a control circuit which sets the gain in the gain switching amplifier;
- a memory which stores a receivable channel frequency of the broadcast signal;
- and
- an operating unit with which is set the gain in the gain switching amplifier, wherein
- the memory stores
- first image information which is a menu screen on which is selected a presetting operation which searches for the receivable channel frequency, and a gain switching operation which switches the gain in the gain switching amplifier by means of the operating unit, and
- second image information which is a gain setting menu screen on which is determined the gain in the gain switching amplifier, wherein
- in the event that an instruction to carry out the presetting operation is issued when the first image information is being displayed, after the receivable channel frequency is found, the receivable channel frequency found is stored in the memory, wherein
- in the event that an instruction to carry out the gain switching operation is issued when the first image information is being displayed, the second image information is displayed, and wherein
- in the event that an instruction to set the gain in the gain switching amplifier is issued by means of the operating unit when the second image information is being displayed, the gain in the gain switching amplifier is set based on the instruction, and the presetting operation is carried out under the set condition.
