The decoder engine incorporates MPEG-1 and MPEG-2 variable length decoding (VLD), de-Quantization, inverse scan, iDCT and hardware-assisted Motion Compensation. By off-loading these tasks to the chipset hardware CPU utilization is greatly reduced, meaning the processing power of the CPU can be allocated for other tasks such as audio decoding, subpicture decoding, decryption and navigation.
