Fast macroblock mode decision for H.264/AVC baseline profile video transcoder based on support vector machines
收藏 引用
MULTIMEDIA SYSTEMS 2012年 第5期18卷 359-372页
作者: Liu, Zhao-Guang Yang, Yang Ji, Xiu-Hua Shandong Econ Univ Sch Comp Sci & Technol Shandong Prov Key Lab Digital Media Technol Jinan Peoples R China Shandong Univ Sch Informat Sci & Engn Jinan 250100 Peoples R China
In video transcoding, accuracy and efficiency of macroblock mode decision are critical issues at the re-encoder side due to the changes in frame size, frame rate, and bit rate. In this paper, a fast macroblock mode de... 详细信息

Intra Mode Selection in Downsizing video transcoder Based on H.264
收藏 引用
INTERNATIONAL JOURNAL OF IMAGING SYSTEMS AND TECHNOLOGY 2009年 第4期19卷 340-349页
作者: Liu, Zhao-Guang Wang, Yu Shandong Econ Univ Sch Comp Sci & Technol Jinan Peoples R China
An intra mode selection scheme is proposed in this work, which supports both downsizing transcoding and re-quantization transcoding simultaneously. In the proposal, a total number of nonzero coefficients in precoded f... 详细信息

video Content-Based Bit Rate Estimation Scheme for Transcoding in IPTV Services
收藏 引用
KSII TRANSACTIONS ON INTERNET AND INFORMATION SYSTEMS 2014年 第3期8卷 1040-1057页
作者: Cho, Hye Jeong Sohn, Chae-Bong Oh, Seoung-Jun ARION Technol Inc AV Res & Dev Lab Anyang Gyeonggi Do South Korea Kwangwoon Univ Dept Elect & Commun Engn Seoul South Korea Kwangwoon Univ Dept Elect Engn Seoul South Korea
In this paper, a new bit rate estimation scheme is proposed to determine the bit rate for each subclass in an MPEG-2 TS to H. 264/AVC transcoder after dividing an input MPEG-2 TS sequence into several subclasses. Vide... 详细信息
