摘要: An apparatus and method a for performing two-pass real time video compression is provided. Tactical decisions such as encoding quantization values are determined in software, whereas functional execution steps performed hardware. By appropriately apportioning the tasks between software hardware, benefits of each type processing exploited, while minimizing both hardware complexity data transfer requirements. One key concept that allows unit to operate architecture pipelining allow B frames be executed out order. buffering frames, motion estimation techniques can tailor bit usage requirements frame, thereby provide more appealing output image.
