Abstract

본 발명은 제1튜너로 방송신호 시청중에 제2튜너에서 예약 녹화가 없으면 제2튜너를 이용하여 타 채널을 검색하여 저장할 수 있도록 한 2튜너 시스템의 텔레비젼 수상기에서 제1튜너로 수신되는 방송 시청시 제2튜너에 의한 방송 채널 설정장치에 관한 것으로, 제1튜너로 선택된 방송신호를 수신하여 시청중에 제2튜너에서 예약 녹화가 없더라도 제2튜너를 이용하여 타 채널을 검색하여 저장하지 못해 제1튜너로 수신되는 방송신호의 각 채널 데이터를 변경하고자 할 경우에는 반드시 제1튜너에 의해 각 채널 데이터를 설정하여 메모리에 저장하여야 하므로 선택된 채널 시청중에 채널을 변경하여 입력할 경우에는 시청중인 화면의 영상이 가려지는 문제점을 해소하기 위하여, 2튜너 시스템의 텔레비젼 수상기에 있어서, 방송국에서 전송되눈 고유번호(ID)를 검색하여 예약 녹화기능이 설정되어 있지 않으면 제1튜너에 설정된 채널을 다시 튜닝하여 튜닝된 데이터와 검색된 타 채널의 데이터를 새롭게 저장하여 TV 제어 수단에 입력하는 튜너 운용수단을 더 포함되게 구성하여 시청자가 제1튜너로 수신되는 방송의 채널을 선택하여 시청중에도 타 채널을 임의로 변경하여 메모리부에 저장할 수 있도록하여 시청자에게 보다 나은 서비스를 제공하므로서, 기존에 선택된 채널 시청중에 채널을 변경하여 입력할 경우에 시청중인 화면의 영상이 가려지는 문제점을 해소하여 텔레비젼 수상기의 신뢰성을 향상시킬 수 있는 것이다.The present invention provides a first tuner when watching a broadcast signal received by the first tuner from a television receiver of a two-tuner system that allows the second tuner to search and store another channel using the second tuner when there is no reserved recording on the second tuner while watching a broadcast signal. The present invention relates to an apparatus for setting a broadcast channel by a second tuner. The first tuner cannot receive and store another channel using the second tuner even if there is no reservation recording on the second tuner while receiving a broadcast signal selected by the first tuner. If you want to change the channel data of the broadcasting signal received by the user, you have to set the channel data by the first tuner and store it in the memory. In order to solve the problem of obstruction, in a television receiver of a two-tuner system, an identification number transmitted from a broadcasting station If the reserved recording function is not set by the searcher, the tuner operating means for retuning the channel set in the first tuner and newly storing the tuned data and the data of the other searched channels and inputting them to the TV control means is further included. When selecting a channel of a broadcast received by the first tuner, the other channel can be arbitrarily changed and stored in the memory unit while watching to provide a better service to the viewer. It is possible to improve the reliability of the television receiver by eliminating the problem of the image of the screen being viewed.
