Abstract

본 발명은 텔레비젼의 채널 선국장치 및 방법에 관한 것으로서, 특히 텔레비젼의 방송의 수신시 동일한 채널의 방송이 2개이상 수신되면 이를 피아이피(PIP : Picture In Picture)형태로 화면에 디스플레이하여 시청자가 이를 보면서 간편하게 최적의 화면을 선택하여 기억시킬 수 있게 하는 텔레비젼의 채널 선국장치 및 방법에 관한 것으로, 지역 특성상 동일한 방송신호가 여러 채널을 통해 수신되는 경우가 빈번히 발생되는데, 일반적인 자동 채널 선국 시스템에 있어서는 동일한 방송신호가 수신될 때 비교판단하는 기능이 구비되어 있지 않아 무조건 방송 신호가 존재하는 모든 채널을 기억한 후 시청자의 판단에 따라 보다 양호한 채널의 번호를 기억하게 되어 있어 선국하는데 시간이 많이 소요될뿐더러 양호한 채널을 선택하는데 어려움이 있고, 상승/하강키를 이용하여 자기가 원하는 방송채널을 확인한 후 원하는 방향으로 진행시켜야 되는 번거로운 문제점이 있었으나, 본 발명에서는 KBPS신호를 통해 방송국명을 인지하여 동일방송국명의 채널이 2개 이상 존재하는 경우 그 채널들을 피아이피화면으로 디스플레이하여 사용자가 최적의 화면을 선택하여 채널을 선국함으로써 채널선국의 간편성이 증대되는 효과가 있게 되며, 채널 안내키를 부가하여 디스플레이된 방송국명 및 해당채널을 선택하여 이에 해당하는 화면을 피아이피화면을 통해 보여줌으로써 시청자가 수신상태를 확실히 인지하여 채널을 선국하는 효과가 있게 된다.The present invention relates to a channel channel selection apparatus and method of a television, and in particular, when two or more broadcasts of the same channel are received when a television broadcast is received, the display is displayed on the screen in the form of a picture (PIP: PIP). The present invention relates to a channel channel tuning apparatus and method for easily selecting and storing an optimal screen while watching. In the characteristic of a region, the same broadcast signal is frequently received through multiple channels. It is not equipped with the function of comparing and judging when a broadcast signal is received, so it is necessary to memorize all the channels where a broadcast signal exists, and to remember the channel number which is better at the discretion of the viewer. Have difficulty selecting channels, Although there is a problem of having to proceed in a desired direction after identifying a desired broadcasting channel by using a strong key, in the present invention, when two or more channels of the same broadcasting station name exist by recognizing a broadcasting station name through a KBPS signal, the channels are avoided. The user can select the optimal screen to tune the channel by displaying it on the IP screen, and the simplicity of channel tuning is increased. By adding the channel guide key, the displayed station name and the corresponding channel are selected to display the corresponding screen. By showing through the PIP screen, the viewer can recognize the reception state to have an effect of tuning the channel.
