    Abstract: A device and a method for generally extracting FGS(Fine Granular Scalability) from SVC(Scalable Video Coding) video with user preference are provided to supply an SVC bit stream having the FGS data according to a consumption environment. An R(Rate)-D(Distortion) data extractor(110) extracts R-D data of more than one space layer by analyzing a bit stream. A user preference collector(120) collects user preference for each space layer. A determination engine(130) determines an optimal bit rate for each space layer by using the bit rate and the user preference. A scaling engine(140) excludes FGS data not corresponding to the optimal bit rate for each space layer.

    Abstract translation: 提供了一种用于从具有用户偏好的SVC(可缩放视频编码)视频中提取FGS(精细粒度可扩展性)的装置和方法,以根据消费环境提供具有FGS数据的SVC比特流。 R(Rate)-D(失真)数据提取器(110)通过分析比特流来提取多于一个空间层的R-D数据。 用户偏好收集器(120)收集每个空间层的用户偏好。 确定引擎(130)通过使用比特率和用户偏好来确定每个空间层的最佳比特率。 缩放引擎(140)排除不对应于每个空间层的最佳比特率的FGS数据。
