Digital broadcasting receiver and a reception method thereof
First Claim
1. A digital broadcasting receiving apparatus comprising:
- a channel information storage unit to store information on a receivable physical channel among physical channels allocated to discriminate digital broadcasting signals transmitted from a plurality of broadcasting stations and a transceiver identification (Tx ID) allocated to discriminate a transceiving region of the broadcasting signal;
an input unit to input a virtual channel of the digital broadcasting signal and a receiving region corresponding to a desired analog broadcasting channel;
a control unit to select the physical channel having the inputted virtual channel, to make a channel selecting priority list when a plurality of the physical channels are selected, and to control the overall system to select and display the broadcasting signal of the first priority channel; and
an on-screen display (OSD) processing unit to display the channel selecting priority list when the broadcasting signal of the first priority channel is displayed.

Abstract
A digital physical receiving apparatus and a receiving method thereof. The digital broadcasting receiving apparatus includes a channel information storage unit to store information on a receivable physical channel among physical channels allocated to discriminate digital broadcasting signals transmitted from a pluarlity of broadcasting stations, and a transceiver identification (Tx ID) allocated to discriminate a transceiving region of the broadcasting signal, an input unit to input a virtual channel of the digital broadcasting signal and a receiving region corresponding to a desired analog broadcasting channel, a control unit to select the physical channel having the inputted virtual channel and making a channel selecting priority list when a plurality of the physical channels are selected, and an on-screen display (OSD) processing unit to display the channel selecting priority list when the broadcasting signal of the first priority channel is displayed. When there are a plurality of the physical channels having the desired virtual channel, the control unit gives first priority to the physical channel having the same Tx ID as the received Tx ID, and determines a channel selecting priority with respect to the rest of the physical channels in an ascending order of the channel number, thereby solving a problem of overlap of the virtual channel.

6. A method of receiving digital broadcasting, comprising the operations of:
-
inputting a receiving region to a system through an inputting device, the system including a Tx ID allocated to discriminate respective transceiving regions;
setting a channel by scanning a receivable physical channel among physical channels allocated to discriminate digital broadcasting signals transmitted from a plurality of broadcasting stations, and storing information on the set physical channel;
inputting a virtual channel of the digital broadcasting signal corresponding to a desired analog broadcasting channel through an inputting device;
detecting the physical channel having the same virtual channel as the inputted virtual channel;
if a plurality of the physical channels are detected, making a channel selecting priority list of the plurality of physical channels; and
displaying the channel selecting priority list through an OSD screen when the broadcasting signal of the first priority channel is displayed. - View Dependent Claims (7, 8, 9)

10. An apparatus used with a digital broadcasting receiving apparatus, comprising:
-
a channel information storage unit to store information on a receivable physical channel among physical channels allocated to discriminate digital broadcasting signals transmitted from a plurality of broadcasting stations and a transceiver identification (Tx ID) allocated to discriminate a transceiving region of the broadcasting signal;
an input unit to input a desired virtual channel number and receiving region;
a control unit to compare the virtual channel of the respective physical channels with the inputted virtual channel to select the physical channel having the same virtual channel as the inputted virtual channel, to count the number of the physical channels selected at the comparison unit, and to make a channel selecting priority list when a plurality of physical channels are counted by arranging the plurality of physical channels in an ascending order; and
an on-screen display (OSD) processing unit to display the channel selecting priority list when the broadcasting signal of the first priority channel is displayed. - View Dependent Claims (11, 12, 13)
