In this chapter the new data structures coding techniques specifically introduced to increase the coding efficiency are described.

Particular emphasis is given to those which may have a significant impact in the error robustness characteristics of \ac{hevc} streams.

This chapter is organized as follows.
|
||||
Section~\ref{Section2:GeneraVideoSystem} introduces the functional blocks of a generic hybrid video coding system, and Section~\ref{Section2:Overview} provides an overview of the \ac{hevc} standard.
|
||||
Then, Section~\ref{Section2:HighLevel} describes the high-level syntax elements which are used to carry relevant information in coded streams.
