Abstract

본 발명은 방송 수신이 가능한 영상기기에서 방송 수신채널 맵핑(Mapping)에 관한 것으로서, 종래의 방송 수신 채널 맵핑장치는 새로운 방송 수신채널이 검색되면 이전에 맵핑되어 있던 수신채널이 모두 지워지기 때문에, 사용자가 평소에 즐겨 시청하던 방송, 또는 외국어 학습을 위해 자주 시청하던 외국방송등이 사용자의 지역이동에 따라 수신감도가 저하되어 검색되지 않게 되면 사용자는 이를 시청하기 위해 전체의 채널을 일일이 눈으로 검색하여 해당 방송 채널을 찾아 기억한 후 시청해야만 하는등 사용자에게 불편함이 초래되는 문제점이 있었다.The present invention relates to mapping of a broadcast reception channel in a video apparatus capable of broadcast reception. In the conventional broadcast reception channel mapping apparatus, when a new broadcast reception channel is found, all previously mapped reception channels are deleted. If the broadcast that you normally enjoy watching, or the foreign broadcast that you frequently watch for foreign language learning, is not detected due to the decrease in receiving sensitivity according to the user's local movement, the user can search the entire channel by eye to watch it. There was a problem that inconveniences occur to the user such as having to watch and remember the broadcast channel.

따라서, 상기 문제점을 해결하기 위한 본 발명은 현재 수신채널 검색동작에서 검색된 수신채널을 메인 채널로 맵핑하고 이전에 맵핑되어 있는 방송 수신채널 중 사용자의 지역이동 등의 용인에 의해 수신감도가 저하되어 현 수신채널 검색동작에서 검색되지 않은 채널을 추가채널로 설정함으로서, 사용자의 지역이동에 의해 수신감도는 떨어지지만 사용자가 시청하고자 하는 채널을 손쉽게 선택하여 시청할 수 있도록 한 방송 수신채널 맵핑장치와 맵핑 제어방법이다.Accordingly, the present invention to solve the above problem is that the receiving sensitivity is reduced by the acceptance of the user's local movement, such as mapping the received channel searched in the current receiving channel search operation to the main channel and the previously mapped broadcast receiving channel By setting the channel not searched in the receiving channel search operation as an additional channel, the receiving sensitivity is reduced due to the local movement of the user, but the broadcast receiving channel mapping device and mapping control method allow the user to easily select and watch the channel to be watched. to be.
