Abstract
Owing to the video distribution over heterogeneous networks, Scalable Video Coding has become a trend in the last years. As the promising candidates for SVC the Wavelet-based solutions should face the challenges aroused by motion estimation and motion compensation. This paper, according to the WSVC coding context, reviews the motion estimation techniques applied in RDWT and MCTF architectures and the corresponding patents. And then a comparison between the close-loop and open loop systems is made to reveal the corresponding advantages and disadvantages of MCTF-based WSVC. The patents involved in bidirectional MEMC, spatial domain MCTF, in-band MCTF, etc. are also reviewed. Finally possible future research directions in WSVC are pointed.
