Abstract

본 발명은 디지털 신호 처리 장치에 관한 것으로서, 특히 부영상 데이터와 온 스크린 디스플레이(On Screen Display; OSD라고도 칭함) 데이터 처리를 단일 블록에서 하기 위한 부영상 데이터 및 온 스크린 디스플레이 데이터 처리 장치에 관한 것이다. 본 발명은 복호된 주영상 데이터를 제1제어 신호에 의하여 혼합비를 결정하는(1-혼합계수)로 곱한 제1신호를 출력하는 제1연산부와, 제2제어 신호에 의하여 주영상 데이터와 부영상데이터의 혼합비를 결정하는 혼합계수를 부영상 데이터에 곱한 제2신호와, 온 스크린 디스플레이 데이터와 혼합계수로 곱한 제3신호를 출력하는 제2연산부, 상기 제1신호와 상기 제2신호 및 제3신호를 합산하는 혼합부 및 상기 복호된 주영상 데이터에 혼합되는 부영상 데이터 또는 온 스크린 디스플레이 데이터 비율을 결정하는 혼합계수, (1-혼합계수)를 출력하는 제어부를 포함함을 특징으로 한다. 본 발명에 의하면 부영상 데이터 및 온 스크린 디스플레이 데이터의 혼합비의 연산을 하나의 연산부에서 처리함으로써, 종래의 기술에 비하여 연산 과정을 단순화하여 연산 시간을 줄일 수 있을 뿐만 아니라, 이로 인하여 원가를 낮출 수 있는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital signal processing apparatus, and more particularly, to a sub-picture data and an on-screen display data processing apparatus for performing sub-picture data and on-screen display (OSD) data processing in a single block. The present invention provides a first operation unit for outputting a first signal obtained by multiplying decoded main image data by a mixing ratio by a first control signal (1-mixing coefficient), and main image data and a sub image by a second control signal. A second operation unit for outputting a second signal obtained by multiplying a sub-picture data by a mixing coefficient for determining a mixing ratio of the data and a third signal multiplied by the on-screen display data by a mixing coefficient, the first signal, the second signal, and the third And a mixing coefficient for determining a ratio of sub-picture data or on-screen display data mixed with the decoded main image data, and a control unit for outputting (1-mixing coefficient). According to the present invention, by processing the operation of the mixing ratio of the sub-image data and the on-screen display data in one operation unit, not only can reduce the calculation time by simplifying the operation process compared to the conventional technology, but also can reduce the cost It works.
