H.264. These techniques and standards have revolutionized the three main in-
dustries including broadcasting, communication and personal computers. This
chapter provides a basic overview of the principle of video coding, with the
focus on the core techniques and various standards. Due to the space limit, a
lot of technical details have to be left out. We also refrain from introducing
complex mathematics, only to the extent that it helps the reader to under-
stand the techniques. However, we hope this chapter could serve as a good
foundation for further study or research work.
Although it is always di
cult to try guessing the future, it looks quite
secure to identify a few basic trends for video coding, notably:
• The importance of new video coding tools will become less obvious as
the existing standards have occupied or are occupying the existing and
emerging markets.
• Comparing to the growth of bandwidth and storage capacity, the progress
of video coding is much less impressive now and it will be even so in future.
• The existing generic video coding scheme has almost reached its theoretical
limit.
• A change of paradigm is needed in order to achieve another 50% of bit
savings future coding schemes are believed to be more specialized and
less generic.
• More intelligent image and video analysis tools are needed so that the
coding is customized to nature of the video.
