- In this letter, a new intra-block coding mode is presented to improve the coding efficiency for band-limited signals. A band-limited block is sub-sampled, and the subsampled signal is coded on the basis of the conventional prediction/transform coding. The rest of the samples are reconstructed by interpolation at the decoder side without any side information. Experimental results show that the proposed algorithm achieves coding gains of 2.7% for common intermediate format (CIF), 4.29% for quarter CIF, and 6.39% for 720p60 sequences against the H.264/AVC JM10.2 reference software. © 2009 ETRI.
