In the past decades, most of the research on image and video compression has focused on addressing high bandwidth- constrained environments. However, for high resolution and high quality image and video compression, as in the case of High Definition Television (HDTV) or Digital Cinema (DC), the primary constraints are related to quality and flexibility. This paper presents a comparison between scalable wavelet-based video codecs and the state of the art in single point encoding and it investigates the obtainable compression efficiency when using temporal correlation with respect to pure intra coding.

Abstract
In the past decades, most of the research on image and video compression has focused on addressing high bandwidth- constrained environments. However, for high resolution and high quality image and video compression, as in the case of High Definition Television (HDTV) or Digital Cinema (DC), the primary constraints are related to quality and flexibility. This paper presents a comparison between scalable wavelet-based video codecs and the state of the art in single point encoding and it investigates the obtainable compression efficiency when using temporal correlation with respect to pure intra coding.| File | Dimensione | Formato | |
