Abstract
Nowadays, video communications between mobile devices are one of the most demanded multimedia services. Since Wyner-Ziv coding provides low cost video encoding, it is a suitable codec to encode video with less resources. On the other hand, the video delivery provided by Scalable Video Coding covers the needs of a wide range of homogeneous networks and different devices. As a consequence, Wyner-Ziv to Scalable Video Coding transcoding can offer a suitable framework to support scalable video communications between low-cost devices. However, the complexity of the transcoder accumulates most of the complexity of both codecs and it must be reduced. In this paper, we introduced an improved Wyner-Ziv to Scalable Video Coding transcoding framework to support homogeneous mobile video communications. The experimental results show that the complexity is reduced around 83.5% without significant Rate-Distortion penalty.
