Method and Apparatus for High Quality Video Reconstruction

Brief Description

A novel method and apparatus to improve the overall quality of a reconstructed video signal at a given transmission rate, or to maintain the current signal quality at reduced transmission rates. 

Background

Spatially scalable video coders are central to video communications over networks and with a diverse set of devices.  These encoders are particularly important when streaming video over networks to devices with a wide variety of display resolutions.  It is difficult to preserve high quality video signals to so many different types of devices while varying the video transmission bit rates to accommodate high network traffic.  High network traffic will cause a decrease in signal transmission rates, reducing the overall quality of the video signal.

Description

Researchers at the University of California, Santa Barbara have developed a novel method and apparatus to improve the overall quality of a reconstructed video signal at a given transmission rate, or to maintain the current signal quality at reduced transmission rates.  The method also employs a prediction scheme to improve video quality by predicting information about future signal data from information given in the currently streaming data.  These characteristics help to vastly improve device video streaming performance and video signal quality for devices with varying display resolutions.

Advantages

• Vast signal quality improvements at a given transmission rate

• Maintained signal quality at reduced bit transmission rates
