Abstract :
To reduce the external memory cost, an efficient 5/3-DWT based embedded compression algorithm is proposed for H.264 decoder. Decoded frames are decomposed into 4×4 blocks which are then compressed into 32-bit or 64-bit segments. The algorithm achieves compression ratio of 28~33% just with a slight quality degradation.
