Experimental Evaluation of a Video Capture Board for Networked Workstations

This thesis examines the architectural issues in the design of a video capture board intended for use in multimedia videoconferencing. The major issues examined are: Control of reception and transmission of multimedia video streams, (i) Quality of service and service provision (ii) Compression requirements and solutions (iii) Data buffering and card connection strategies (iv) Handling multiple video streams Results of measurements for prototype boards designed and constructed at Penn are also given.
