Technique for Calculating SSD & Encoding Video Signal    

A technique and equipment for calculating the Sum of Squared Difference (SSD) and encoding a video signal.

Overview

The technology relates to technique for calculating the SSD between an original block and a reconstructed block of image or video data and/or technique for determining the distortion caused by encoding a block of image or video data where the appropriate encoding mode is selected from a plurality of possible modes.

The invented fast algorithms could reduce the cost and power consumption of the digital video encoding devices.

Primary Application of the Technology

All the digital video encoding devices such as digital video recorder, digital camera, digital video cam, high-definition video system can use the invented fast algorithms. The market is huge in both portable devices and home entertainment products.
