Fast adaptive GOP design for H.264/SVC
Jun-Ren Ding, Jar‐Ferr Yang · 2007
In order to concurrently provide different video services for diverse access devices, the scalable quality and complexity services in a single bit stream offered by H.264-based scalable video coding (H.264/SVC) has gained a lot of attentions recently. However, the motion-compensated temporal filtering (MCTF) structure consumes a large amount of operation time when combined with Core Experiment 2 (CE2), which implements adaptive GOP detection (AGD). In this paper, we suggest a video content variation (VCV) feature to implement fast AGD method by using block based classification before executing MCTF. Based on the JSVM 7.0 software, the simulation results show that the proposed method reduces about 67% of the operation time consumed on average as compared to the CE2.
