However rate-distortion performance is not the only criteria for us to choosing the
encoding standard, the hardware complexity is also very important. Take the com-
plexity and resources requirement into account, the H.264 and JPEG 2000 is far more
complex than JPEG XR [8,9]

Conclusion
In this paper, we firstly introduced JPEG XR standard, then we deeply evaluated the
influence of three parameters on rate-distortion curve, including TileSize, OverlapFil-
ter and Trimflexbits. It is found that TileSize=512x512, OverlapFilter=1 and Trim-
flexbits=0 is best combination for the high compression efficiency of 4K images.
After that, a simple evaluation methodology has been used to compare the com-
pression performance between JPEG XR, JPEG 2000 and AVC inter and intra profile
for compression of 4K video sequences. The result of our study shows that the AVC
inter (N=15), JPEG 2000 and JPEG XR (OF=1) provide comparable compression
efficiency in condition of high quality compression. The advantages of JPEG XR
become more obvious with the higher PSNR. Meanwhile JPEG XR exhibits signifi-
cantly lower computational demands and hardware complexity, so it is the most ap-
propriate standard for the need of the near-lossless compression of 4K video.
