Abstract: This document introduces VYA, a procedure for video-oriented use of YAPI, the Y-chart Application Programmer's Interface developed at Philips Research Eindhoven for modeling and simulating signal processing applications. VYA resulted from a cooperation between the developers of YAPI and video algorithm developers at Philips Research Briarcliff. VYA-compliant software modules are plugable by virtue of standardized interfaces for video and control signals, while a high level of re-usability is obtained through a carefully chosen application of YAPI. VYA focuses on communicating rectangular images in applications with YUV and/or RGB input and/or output.
