Abstract
We have developed an H.264/MPEG-4 video codec IP for mobile applications such as digital still cameras (DSCs) and digital video cameras (DVCs) The codec is capable of encoding/decoding HD sized moving pictures (1280 pixels by 720 lines at 30 fps) in real-time at an operating frequency of 144 MHz, and SD sized at 54 MHz. The original algorithms employed in the codec realize low power of 64 mW for encoding HD with high picture quality equivalent to JM reference encoder.
