An efficient channel allocation technique for multiple videos-on-demand

There are several broadcasting protocols for video-on-demand (VOD). Most of these protocols are tailored to handle the distribution of single video for a specific range of request arrival rates. In order to distribute multiple videos, broadcasting protocols like fast broadcasting (FB), new pagoda broadcasting (NPB) and universal distribution (UD) require more channels that are proportional to the number of hot videos to be broadcast. We present here an efficient broadcasting protocol in which, channel numbers can be reduced when multiple videos are broadcast either simultaneously or asynehronously. During the low to moderate request rates, our protocol performs best as similar to other reactive protocols and saves bandwidth and requires lesser number of channels as compared to other proactive or reactive protocols.
