Abstract

본 발명은 현재 방송중인 KBPS 신호를 이용하여 다양한 프로그램을 수신하는 TV 또는 VCR 등에서 입력신호에 따라 각 프로그램에 가장 적절한 음장을 부가하는 최적 음장 부가장치 및 방법에 관한 것이다.The present invention relates to an optimum sound field adding device and method for adding the most appropriate sound field to each program according to an input signal in a TV or VCR that receives various programs using a KBPS signal currently being broadcast.

종래의 음장 부가장치는 입력신호의 종류에 무관하게 일정하게 음장을 부가하여 오히려 원음의 특성을 저해하는 문제점이 있다.The conventional sound field adding device has a problem in that a sound field is constantly added regardless of the type of the input signal, thereby degrading the characteristics of the original sound.

그러나 본 발명의 최적 음장 부가장치 및 방법은 현재 방송되는 프로그램의 송신 방송국과 이에 따른 방송번호로 현재 프로그램의 종류를 확인하여 이 프로그램에 가장 적합한 음장의 형태를 알아내어 상기 가장 적합한 음장의 형태를 입력되는 오디오 신호에 부가한다.However, the optimum sound field apparatus and method according to the present invention identify the type of the current program by checking the type of the current program by the transmitting station of the currently broadcasted program and the broadcast number according thereto, and input the form of the most suitable sound field. To the audio signal being added.

여기서 방송 프로그램이 변경된다면, 이에 따른 KBPS 신호가 방송신호에 함께 수신되므로 이에 적합하도록 적절한 음장으로 바뀌게 되므로 사용자에게 거부감이 없도록 최적 음장을 제공한다.In this case, if the broadcast program is changed, the KBPS signal is received in the broadcast signal, and thus is changed to an appropriate sound field so as to be suitable for the broadcast program.
