Abstract:
1. An apparatus, comprising: a reduced resolution update based video encoder for encoding video data divisible into macroblocks, the reduced resolution update based video encoder including a hardware memory device for storing reduced resolution neighboring pixels and a hardware downsampler for downsampling a full resolution macroblock to obtain a reduced resolution macroblock; where the video encoder is further configured to perform intra prediction for the reduced resolution macroblock using the stored reduced resolution neighboring pixels, where the video encoder is further configured to encode residual data for the reduced resolution macroblock and to decode the residual data for the reduced resolution macroblock to form a reconstructed low resolution intra-coded coded macroblock, where the video encoder further includes a hardware upsampler for upsampling the reconstructed low resolution intra-coded macroblock to form a full resolution intra-coded macroblock, and where the hardware memory device is further utilized for storing reconstructed low resolution intra-coded macroblocks for subsequent intra-prediction of neighboring macroblocks.
