PIXAR Image Computer: Specifications, Applications and Uses at the Advanced Television Test Center

The Advanced Television Test Center is the primary test facility for the evaluation of the Proposed Advanced Television Systems(ATV) under consideration by the Federal Communications Commission(FCC). In order to evaluate the still image quality and video performance of these systems the ATTC selected the PIXAR Image Computing System. Century Computing, Inc of Laurel, MD is the system integrator and software application developer. — This paper will discuss the applications and uses of the PIXAR during ATV testing and the creation of the test images from a set of ultra-high resolution source images. The downsampling of the source images was a challenge and required a novel extension of the native PIXAR filter algorithm. Special test patterns, developed with the PIXAR, used to objectively analyze and quantify ATV system video performance are discussed. — Finally, future improvements and additions to the PIXAR Image Computing system will be discussed
