摘要
根据数字视频监控系统的技术特点,开发研究了有利于进行视频监控的可扩展性编码全新技术,并设计一个针对该编码技术的视频传输方案。提出的分层编码算法,不同于传统的空域可扩展性编码,针对视频监控的特点,该算法生成两个基本层码流,分别对应原图像分辨率的1/4和1/16大小,然后在空域扩展生成3个增强层码流,各基本层和增强层在空间位置上不重叠,并且基本层可以独立解码。
In this paper,according to the technical characteristics of digital video monitoring system,a scalable coding new technology which is benefit to video monitoring is developed,and a scheme of video transmission for the coding technology is provided.In this paper,the researched layered coding algorithm is different from the traditional spatial scalable coding.This paper is aiming at the characteristics of video monitoring.The algorithm generates two base layer streams,respectively corresponding to the 1/4 and 1/16 of the original image resolutions.And then it extends in the spatial domain to generate three enhancement layer code streams.All the base layers and enhancement layers do not overlap in space positions,and the base layer can be decoded independently.
