티브이 수신장치의 채널 설정/탐색 방법{CHANNEL SETTING/SEARCHING METHOD FOR TELEVISION}How to set / search for TV receivers {CHANNEL SETTING / SEARCHING METHOD FOR TELEVISION}

본 발명은 티브이 수신장치의 채널 설정/탐색 방법에 관한 것으로, 특히 사용자가 리모트 컨트롤러의 채널 탐색 버튼을 누르는 횟수에 따라 채널 탐색 범위를 조정하고 자동으로 채널을 탐색할 수 있게 한 티브이 수신장치의 채널 설정/탐색 방법에 관한 것이다.The present invention relates to a channel setting / search method of a TV receiver, and more particularly, to a channel of a TV receiver that adjusts a channel search range and automatically searches a channel according to the number of times a user presses a channel search button of a remote controller. It relates to a setting / navigation method.

종래 기술에 따른 티브이의 채널탐색은 선국된 방송 채널 신호의 유무를 판별하여 신호가 존재하는 채널만을 메모리에 기억시키고 사용자가 채널을 선택할 때 사용한다. 자동 채널 탐색인 경우 티브이 수신장치는 공중파 디지털/아날로그 채널과 케이블 채널을 채널 번호 순서대로 탐색하면서 신호가 존재하는 채널만을 검출하여 저장하고 탐색 후 사용자가 채널 업다운 키를 누르면 메모리에 저장된 채널 순서대로 튜닝한다.The TV channel search according to the prior art determines whether a tuned broadcast channel signal exists and stores only the channel in which the signal exists in the memory and is used when the user selects a channel. In case of automatic channel search, the TV receiver searches over the air digital / analog channel and cable channel in the order of channel number, detects and stores only the channel where the signal exists, and then tunes in the order of the channels stored in memory when the user presses the channel up and down keys. do.

그러나, 상기와 같은 종래 기술에 있어서, 일부 채널만을 탐색하거나 현재 채널을 기준으로 채널 탐색 방향을 변경하고자 할 경우 사용상 불편과 특히 디지털 티브이의 자동 채널 탐색인 경우에는 긴 채널 탐색 시간으로 인해 사용자에게 불편함을 주는 문제점이 있다.However, in the prior art as described above, it is inconvenient for the user to search only some channels or to change the channel search direction based on the current channel, and inconvenient for the user due to the long channel search time especially in the case of automatic channel search of the digital TV. There is a problem.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 창안한 것으로, 사용자가 리모트 컨트롤러의 채널 탐색 버튼을 누르는 횟수에 따라 기 설정된 채널 탐색 설정에 따른 자동 채널 탐색을 수행하거나 채널 탐색 범위를 수동으로 설정한 후 채널을 탐색할 수 있도록 한 티브이 수신장치의 채널 설정/탐색 방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, and according to the number of times a user presses a channel search button of a remote controller, an automatic channel search according to a preset channel search setting or a channel search range is manually set. It is an object of the present invention to provide a channel setting / searching method of a TV receiver capable of searching for a later channel.

As shown in FIG. 1, a tuner 1 for converting an RF signal received through an antenna into an IF signal corresponding to the set channel when the channel is set; A SAW filter unit 2 for band-filtering the converted IF signal; A down converter (3) for converting the filtered IF signal into a baseband signal; A VSB demodulator (4) for converting the converted baseband signal into a digital signal by using a provided clock signal to demodulate the VSB signal and detect the presence of a signal; A remote controller 5 having a channel search button for channel search and channel tuning; Channel 6 of the TV receiver of the present invention in a device configured in the same manner as a conventional device, comprising a memory 6 for storing a tuner and channel data according to a control signal corresponding to each button from the remode controller 5. Describe the search method.

또한, 도 2는 본 발명 티브이 수신장치의 채널 설정/탐색 방법에 대한 동작 흐름도로서, 이에 도시한 바와 같이 채널 탐색 키의 눌림을 대기하고 있는 중 채널 탐색 키가 눌리면 사용자가 채널 탐색 키를 누르는 횟수를 판단하여 한 번 누르면 미리 설정된 채널 탐색 범위에 맞게 자동으로 채널을 탐색하는 제1단계(S10, S11, S14, S15, S13)와; 상기 사용자가 채널 탐색 키를 두 번 누르면 사용자에게 채널 탐색 설정 메뉴를 표시하여 사용자로부터 채널 탐색 범위를 설정받은 후 이 채널 탐색 범위에 맞게 자동으로 채널을 탐색하는 제2단계(S12, S13)로 이루어진 것으로 본 발명의 일실시예를 설명한다.FIG. 2 is a flowchart illustrating a method for setting / searching a TV receiver of the present invention. As shown in FIG. 2, when the channel search key is pressed while waiting for the channel search key to be pressed, the user presses the channel search key. Determining and pressing once to automatically search for a channel according to a preset channel search range (S10, S11, S14, S15, and S13); When the user presses the channel search key twice, the channel search setting menu is displayed to the user to receive the channel search range from the user, and then the second step (S12, S13) automatically searches for the channel according to the channel search range. It will be described an embodiment of the present invention.

본 발명에 따른 티브이 수신장치의 채널 설정/탐색 방법은 도 3에 도시된 바와 같이, 채널 탐색 설정 메뉴에서 신호원 선택(공중파/케이블), 방송 형태 선택(아날로그/디지털/케이블 방송), 탐색 채널 범위 선택(시작/마지막 채널 번호), 탐색 채널 간격 선택, 탐색 방향(순방향/역방향) 선택과 같은 항목에 대해서 사용자가 원하는 채널 탐색 조건을 자유롭게 미리 설정할 수 있도록 한다.As shown in FIG. 3, the channel setting / searching method of the TV receiver according to the present invention includes a signal source selection (airwave / cable), a broadcasting type selection (analog / digital / cable broadcasting), and a search channel in a channel search setting menu. The user can freely set a desired channel search condition in advance for items such as range selection (start / last channel number), search channel interval selection, and search direction (forward / reverse direction) selection.

사용자가 리모트 컨트롤러(5)의 채널 탐색 키를 누르면 사용자의 채널 탐색 명령에 따라 마이컴(7)이 이를 인식하여 상기 지정된 채널이 설정되도록 채널의 PLL(Phase Lock Loop) 데이터를 연산하고 튜너(1)에 명령을 내린다.When the user presses the channel search key of the remote controller 5, the microcomputer 7 recognizes this according to the user's channel search command and calculates PLL (Phase Lock Loop) data of the channel so that the designated channel is set and the tuner 1 Give a command to

채널 탐색 키가 한 번 눌리면 마이컴(7)은 채널 탐색 설정 메뉴에 미리 설정된 채널 탐색 범위에 맞게 자동 채널 탐색을 수행하고 상기 채널 탐색 키가 연속해서 두 번 눌리면 사용자에게 채널 탐색 설정 메뉴를 표시하고 사용자로부터 채널 탐색 범위를 설정받은 후 채널 탐색을 수행한다.When the channel search key is pressed once, the microcomputer 7 performs the automatic channel search according to the channel search range preset in the channel search setting menu, and when the channel search key is pressed twice in succession, the user displays the channel search setting menu and the user After receiving the channel search range from the user, channel search is performed.

VSB 복조부(4)는 신호를 복조하여 동기 신호 락 유무를 검출하여 해당 채널에서의 신호 유무를 판단하여 신호가 유효하면 해당 방송 채널 정보를 저장하고 유효하지 않으면 메모리(6)에서 삭제한다. 이어서 상기 채널 탐색 설정 조건에 따라 마지막 채널까지 상기 단계를 수행하여 채널 탐색을 완료한다.The VSB demodulator 4 demodulates the signal to detect the presence or absence of a synchronous signal lock to determine whether there is a signal on the corresponding channel, and stores the broadcast channel information if the signal is valid and deletes it from the memory 6 if it is invalid. Subsequently, the channel search is completed by performing the above steps up to the last channel according to the channel search setting condition.

사용자가 아무런 채널 탐색 조건을 미리 설정하지 않았을 때는 최소 채널 번호에서 최대 채널 번호까지 채널 간격은 한 채널씩, 탐색 방향은 순방향으로 전 채널에 대해서 자동 탐색을 수행한다.When the user does not set any channel search condition in advance, the channel search is performed by one channel from the minimum channel number to the maximum channel number, and the search direction is forward.

이상에서 상세히 설명한 바와 같이, 본 발명은 사용자가 원하는 채널 탐색 조건을 자유롭게 설정할 수 있도록 하여 채널 탐색 시간을 줄일 수 있고 채널을 변경할 때 빠르게 이동할 수 있으며 사용자에게 탐색 선택 범위를 넓혀 주어 자동 채널 탐색 기능을 사용자가 원하는 형태로 변경할 수 있는 효과가 있다.As described in detail above, the present invention allows the user to freely set a desired channel search condition, thereby reducing channel search time, moving quickly when changing a channel, and expanding the search selection range to the user to provide an automatic channel search function. There is an effect that can be changed to the shape desired by the user.
