Abstract

At the present time there are three major video standards in the world. With the emergence of extended quality and high-definition TV systems, the video environment is becoming more and more complicated. In a video research laboratory, it is desirable to have a simulation tool that can perform the following functions: (1) acquire video data in real time, (2) allow for computer access and processing, and (3) play back the processed data in real time. To investigate the visual effects of various video formats and format conversions, it is necessary to design the simulation system such that it can accomodate different video formats at both the input and output stages. In this paper a versatile video sequence processing simulation system developed at Bell Communications Research is presented. Video signals can be captured either in the single frame mode or in the sequence mode. Both the capture and display formats are flexible. Dynamic random access memory (DRAM) chips are used to construct the frame store. Its random access feature allows video data to be read out and played back palindromically*. After its implementation for more than one year, the validity and flexibility of this system has been verified.
