Abstract:
The proportion of video traffic on the internet is expected to reach 82% by 2022, mainly
due to the increasing number of consumers and the emergence of new video formats with more
demanding features (depth, resolution, multiview, 360, etc.). Efforts are therefore being made to
constantly improve video compression standards to minimize the necessary bandwidth while retaining high video quality levels. In this context, the Joint Collaborative Team on Video Coding has
been analyzing new video coding technologies to improve the compression efficiency with respect to
the HEVC video coding standard. A software package known as the Joint Exploration Test Model
has been proposed to implement and evaluate new video coding tools. In this work, we present
parallel versions of the JEM encoder that are particularly suited for shared memory platforms, and
can significantly reduce its huge computational complexity. The proposed parallel algorithms are
shown to achieve high levels of parallel efficiency. In particular, in the All Intra coding mode, the
best of our proposed parallel versions achieves an average efficiency value of 93.4%. They also
