Abstract

In this paper, we propose a model for estimating the buffer storage for continuous delivery of video data. For this, the physical channel is divided into logical channels and the videos running on the video server into segments. The video segments are transmitted through logical channels using the time-division multiplexing (TDM) technique. Switching between two consecutive video segments in a logical channel creates some delay during which no data is transmitted and that delay, called jitter delay, is of random nature. In this work, jitter delay is incorporated while estimating the buffer storage. The buffer storage is a random variable and its probability density function is derived. This study is important for applications related to on-demand services such as cable TV, news-on-demand, movie-ondemand, audio-on-demand, etc.
