Abstract
A low complexity method for directly decoding low-resolution video frames from compressed high-resolution video content that were encoded using predictive coding toques, such as the H264 video coding standard, is disclosed. The decoding resolution is inversely proportional to the decoding complexity. Thus, a smaller decoding resolution yields higher computation and power savings. Low-frequency coefficients of 2 Dimensional transformed predictions are added to low-frequency coefficients of a transformed residual error. Low-frequency coefficients of the reconstructed data are then inversely transformed, having a smaller size transform. Further computational and power savings are obtained by reconstructing only those referenced pixels necessary for accurate decoding of proceeding Intra blocks.
