모바일 디바이스를 위한 H.264기반의 계층구조 영상 부호화 알고리즘

Recently, multimedia services such as mobile broadcasting and video conference are increasing. To provide real-time video transmission using mobile devices as well as the bitrate-adaptation according to network conditions, the video encoding algorithm should meet both the low computational complexity and contents scalability. Based on the H.264, SNR and temporal scalability are implemented and a fast mode decision method is proposed. The experimental results show that the proposed method provides significant reduction in computational complexity.
