摘要：
There are provided encoders, decoders and corresponding encoding and decoding methods. A reduced resolution update (RRU) based video encoder for encoding video data divisible into macroblocks includes a memory device (150), a downsampler (102), INTRA coding means (165), an encoder (115, 120), a decoder (199), and an upsampler (140). The memory device (150) is for storing reduced resolution neighboring pixels. The downsampler (102) is for downsampling a full resolution macroblock to obtain a reduced resolution macroblock. The INTRA coding means (165) is for performing INTRA prediction for the reduced resolution macroblock using the stored reduced resolution neighboring pixels. The encoder (115, 120) is for encoding residual data for the reduced resolution macroblock. The decoder (199) is for decoding the residual data for the reduced resolution macroblock to form a reconstructed low resolution INTRA coded macroblock. The upsampler (140) is for upsampling the reconstructed low resolution INTRA coded macroblock to form a full resolution INTRA coded macroblock. The memory device (150) is further for storing a right column and a bottom row of the reconstructed low resolution INTRA coded macroblock.
