The next-generation video coding standard of
High-Efficiency Video Coding (HEVC) is especially efficient
for coding high-resolution video such as 8K-ultra-highdefinition
(UHD) video. This paper provides the
latest developments in HEVC related technologies,
implementations and systems with focus on further research.
The fractional-pel interpolation filter adopted in H.264/AVC
improves motion compensation greatly. Recently, a new
DCT-based fractional-pel interpolation filter is adopted in
the oncoming standard HEVC. We are interested in the
differences between these two types of fractional-pel
interpolation filters. In this paper we describe the derivations
of fractional-pel interpolation filters in HEVC and
H.264/AVC in detail, and compare them on properties of
frequency responses. In this project find that the half-pel
interpolation filters in HEVC and H.264/AVC are very
similar, but the low-pass properties of quarter-pel
interpolation filters in HEVC are much better than those in
H.264/AVC. The fractional-pel interpolation filters (6-tap
FIR and Average) adopted in H.264/AVC improves motion
compensation greatly.

In the family of video coding standards, HEVC has the
promise and potential to replace/supplement all the
existing standards (MPEG and H.26x series including
H.264/AVC)... Researchers are exploring about reducing
the HEVC encoder complexity.Comprehensive
comparison both in coding performance and complexity
between the fractional-pel interpolation filters in HEVC
and those in H.264/AVC is given by this paper. The
evolution process of fractional-pel interpolation filter in
HEVC is described in detail. We find that the frequency
responses of quarter-pel interpolation filters in HEVC are
much better than those in H.264/AVC.
