초록

디지털 영상은 영상압축이나 기타 다양한 디지털 처리에 용이한 장점이 있는 반면 위/변조가 상대적으로 용이하기 때문에 그에 대한 대응을 위한 다양한 디지털 워터마킹 기법이 개발되었다. 워터마킹 기법은 공간 또는 주파수 영역에서의 다양한 적용에 가능한데, 본 연구에서는 디지털 콘텐츠 대부분이 압축되어 전송, 저장되는 추세와, 최근 대부분의 멀티미디어 동영상 코덱 표준으로 채택이 되고 있는 H.264/AVC 언코더를 기반으로 한 워터마크 삽입을 실시간으로 수행하기 위한 기법을 제시한다.

Although digital image has many advantages including digital image compression and various image processing techniques, the it has the weakness of easy manipulation which led to the development of many digital watermarking techniques. There are various types of digital watermarking algorithms for spatial and spectral domains. This paper presents a watermarking implementation for H.264/AVC codec which is adapted for many multimedia standards.
