Macroblock level hybrid temporal-spatial prediction for H.264/AVC

In this paper, a novel macroblock level hybrid temporal-spatial video coding framework is proposed. In this framework, a new Hybrid Temporal Spatial Prediction (HTSP) coding mode is adopted for each macroblock. Macroblock is divided into two partitions. The first partition is temporally predicted using motion compensation and encoded, while the second partition is spatially predicted using the reconstruction of the first partition. Experimental results show that up to 0.4 dB coding gain and 0.2 dB on average can be achieved for HD sequences.
