Video coding standards, such as MPEG-4 Part II and H.264/AVC, follow a block-based hybrid coding design which employs inter picture prediction to exploit temporal dependency and transform coding to exploit spatial dependency. This paper presents a video encoder preprocessing method which is based on transform and quantization to improve coding efficiency(More)
Video coding standard H.264/AVC employs zig-zag scan and field scan to map transform coefficients from two dimensional matrix to one dimensional array. The zig-zag scan is used for transform coefficients in frame macroblocks (MBs), and the field scan is used in field MBs. This paper presents a most probable scan mode (MPSM) decision for H.264 inter picture(More)
