Abstract

This paper proposes the Variable-bit-rate TDM (VTDM) switch architecture, which not only has the advantage of TDM but also can support VBR traffic. The VTDM frame is designed for accommodating video data by enlarging the size of time slot and synchronizing the VTDM frame length with the video frame interval. The double-buffer scheme allows a guarantee of maximum switching delay and a slight delay jitter. It will be shown that adequate performance can be achieved by simply applying traffic shaping. By utilizing the header information of VTDM frame and the scheduler operation, an intelligent priority control, leading to picture quality attainment, can be implemented.
