摘要

在MPEG-7标准中定义了转码提示，以提供更好的质量或降低转码应用程序的复杂性。本文:1)从结构和语义两个角度定义了实用的转码提示层次;2)针对可生成转码提示的三种应用场景;3)基于检索到的低层次MPEG特征，提出了针对不同应用场景的转码提示生成器架构。

Building MPEG-7 transcoding hints from intrinsic characteristics of MPEG videos

Transcoding hints are defined in the MPEG-7 standard to provide better quality or reduced complexity of transcoding applications. The paper: 1) defines practical transcoding hint hierarchies from both structural and semantic perspectives; 2) addresses three application scenarios from which transcoding hints can be generated; 3) proposes architectures of transcoding hint generators for different application scenarios, based on retrieved low-level MPEG characteristics.
