%X Wyner--Ziv (WZ) to scalable video coding (SVC) transcoding can offer a suitable framework to support scalable video communications between low-cost devices. In addition, the video delivery provided by SVC covers the needs of a wide range of homogeneous networks and different devices. Despite the advantages of the video transcoding framework, the transcoder accumulates high complexity and it must be reduced in order to avoid excessive delays in communication. In this article, an approach for WZ to SVC transcoding is presented. The information generated during the first stage is reused during the second one, and as a consequence the time taken by the transcoding is reduced by around 77.77%, with a negligible rate-distortion penalty.
