A display device for receiving broadcast channels and bands, comprising: a key input unit configured to input a request command from a user; a memory unit configured to store information about each band and channel configuration information in each band; a tuner unit configured to search broadcast channels of each specific frequency band of each band including a first band and a second band according to a channel search command input from the key input unit, wherein the tuner unit is adapted to perform a channel search while sequentially increasing a channel number of the broadcast channel by using the stored band information and channel configuration information, wherein the tuner unit is configured to sequentially search a first channel of the second band after a channel search operation of all broadcast channels in the first band is completed; and a control unit configured to skip channels or a band from a current search channel or band to a next channel or band without a channel search operation when a skip command is inputted from the key input unit by the user during search of the broadcast channels, characterised in that: the controller unit is configured to set a start channel number for a channel re-search within a skip section of the skipped band or channels if a channel re-search command is inputted from the key input unit by the user during search of the broadcast channels, the control unit is configured to reduce a current search channel number within the skip section of the skipped band or channels in reverse order during an input of the channel re-search command, the control unit is configured to stop the channel number reduction, if the input of the channel re-search command is disabled during the channel number reduction, the control unit is configured to set the channel number set at the stop point as the start channel number for the channel re-search, and the control unit is configured to re-perform sequentially searching broadcast channels from a broadcast channel corresponding to the start channel number. a key input unit configured to input a request command from a user; a memory unit configured to store information about each band and channel configuration information in each band; a tuner unit configured to search broadcast channels of each specific frequency band of each band including a first band and a second band according to a channel search command input from the key input unit, wherein the tuner unit is adapted to perform a channel search while sequentially increasing a channel number of the broadcast channel by using the stored band information and channel configuration information, wherein the tuner unit is configured to sequentially search a first channel of the second band after a channel search operation of all broadcast channels in the first band is completed; and a control unit configured to skip channels or a band from a current search channel or band to a next channel or band without a channel search operation when a skip command is inputted from the key input unit by the user during search of the broadcast channels, the controller unit is configured to set a start channel number for a channel re-search within a skip section of the skipped band or channels if a channel re-search command is inputted from the key input unit by the user during search of the broadcast channels, the control unit is configured to reduce a current search channel number within the skip section of the skipped band or channels in reverse order during an input of the channel re-search command, the control unit is configured to stop the channel number reduction, if the input of the channel re-search command is disabled during the channel number reduction, the control unit is configured to set the channel number set at the stop point as the start channel number for the channel re-search, and the control unit is configured to re-perform sequentially searching broadcast channels from a broadcast channel corresponding to the start channel number.
