With the emergence of the High Efficiency Video Coding (HEVC) standard, significant additional video compression improvements have recently been provided, notably around 50% increased compression performance regarding the previously available standard video coding solutions. Moreover, the same requirements which demanded some years ago for a scalable extension of the H.264/AVC standard, named Scalable Video Coding (SVC) are now again demanding the development of a scalable extension of the HEVC standard, meaning that an HEVC compliant base layer should be adopted. In this context, this paper serves three main purposes: first, it reports the recent efforts towards developing a scalable video coding framework based on the HEVC standard; next, it reviews the current compression performance for quality scalability solutions against the most relevant available alternatives, notably the SVC standard quality scalable solutions and the H.264/AVC and HEVC simulcasting and single-layer solutions; finally, it discusses the possible architectural designs for the scalable HEVC extension to bring a clearer view about the advantages and disadvantages of each technical approach.
