Latest Patents

Marco Quacchia holds a patent for a "Method and apparatus for introducing reference impairments into video signals." This invention provides a systematic way to introduce reference impairments into pictures, which are essential for conducting subjective tests on digital video signals. The method adheres to the ITU-T Recommendation P.930 and generates specific distortions, such as blockiness and edge busyness. By analyzing movement characteristics, the method identifies blocks affected by actual subject movement and modifies their luminance values accordingly. Additionally, it applies randomly chosen echoes to create the second distortion, enhancing the testing process.
