  1. Overview on Scalable Video Coding - II Chuan-Yu Cho

  2. Outline • HHI and MS SVC Codecs • Scalable Video Model 3.0

  3. SVC: 68th meeting • 14 full proposals in two categories • Category 1: MCTF/2D Wavelet • Category 2: AVC based (incl. AVC/MCTF) • Core Experiments (CE) • Reference model (software) = the best performing scheme in each category • Category 1: (MCTF/2DWT) Microsoft Research Asia • Category 2: (AVC/MCTF) HHI • Result of Core Experiments will be used for decision to adopt one complete codec architecture into the WD. From: NCTU 69th MPEG meeting report
