O padrão de codificação de vídeo H.264/AVC emprega codificação de transformação para explorar a correlação espacial em resíduos de predição entre imagens. Este artigo apresenta um deslocamento DC baseado em bloco para explorar ainda mais a correlação em blocos espacialmente vizinhos e fornece ao H.264/AVC um desempenho aprimorado de eficiência de codificação. O método proposto aplica o deslocamento DC ao resíduo de predição entre imagens e codifica o sinal residual compensado pelo deslocamento. O deslocamento DC é derivado de resíduos reconstruídos em blocos vizinhos. Nenhum bit adicional é necessário para a representação do deslocamento DC. Os resultados da simulação relatam que o método proposto produz uma redução média de 2.67% na taxa de bits para vídeo de alta resolução em relação ao perfil de linha de base H.264.

Abstract: Video coding standard H.264/AVC employs transform coding to explore spatial correlation in inter picture prediction residue. This paper presents a block based DC offset to further explore the correlation in spatially neighboring blocks and provides H.264/AVC an enhanced coding efficiency performance. The proposed method applies DC offset to inter picture prediction residue, and encodes the offset compensated residual signal. The DC offset is derived from reconstructed residue in neighboring blocks. No additional bits are required for the DC offset representation. Simulation results report that the proposed method yields an average of 2.67% bit rate reduction for high resolution video over the H.264 baseline profile.
