ABSTRACT:
An Inverse Transform (IT) conforming to MPEG AVC I_PCM that offers better video image quality than the MPEG-2/H.263 based video decoders and real time motion picture processing at 30 frames/seconds is described. The IT module performs 4×4 Inverse Integer transform for AVC for MPEG-2 operations on a given macro block (MB) and all its sub blocks. The IT is the third module in the data flow pipeline of a video decoder, the first two being a variable length decoder (VLD) and an inverse quantizer (IQ). The IT module gets its inputs from IQ module and feeds its processed output to a Motion compensation unit/intra-prediction (MCU-IP) module, thus reconstructing the video picture.
