چکیده

Broadcasting protocols can improve the efficiency of video on demand services by reducing the bandwidth required to transmit videos that are simultaneously watched by many viewers. It has been recently shown that broadcasting protocols using a very large number of very low bandwidth streams for each video required less total bandwidth than protocols using a few high-bandwidth streams shared by all videos. We present a hybrid broadcasting protocol that combines the advantages of these two classes of protocols. Our pagoda broadcasting protocol uses only a small number of high-bandwidth streams and requires only slightly more bandwidth than the best extant protocols to achieve a given maximum waiting time.

A Reactive Broadcasting Protocol for Video on Demand

Broadcasting can reduce the cost of video on demand services by distributing in a more efficient fashion videos that are simultaneously watched by many viewers. Rather than waiting for individual requests, broadcasting schedules repeated broadcasts of the various segments of a video ahead of time. Hence it performs best when it is used to distribute videos that are watched concurrently by hundr...

A Universal Distribution Protocol for Video-on-demand

Most existing distribution protocols for video-on-demand are tailored for a specific range of request arrival rates and do not perform well beyond that range. We present a universal distribution protocol based on Juhn and Tseng's fast broadcasting protocol. Our protocol performs as well as the best reactive protocol at low to moderate request arrival rates and reverts to the fast broadcasting p...

Efficient Broadcasting Protocols for Video on Demand

Broadcasting protocols can improve the efficiency of video on demand services by reducing the bandwidth required to transmit videos that are simultaneously watched by many viewers. We present here two broadcasting protocols that achieve nearly the same low bandwidth as the best extant broadcasting protocol while guaranteeing a lower maximum access time. Our first protocol, cautious harmonic bro...

A Low Bandwidth Broadcasting Protocol for Video on Demand

Broadcasting protocols can improve the efficiency of video on demand services by reducing the bandwidth required to transmit videos that are simultaneously watched by many viewers. We present here a polyharmonic broadcasting protocol that requires less bandwidth than the best extant protocols to achieve the same low maximum waiting time. We also show how to modify the protocol to accommodate ve...
