In order to design a high scalable video delivery technology
for VoD systems, two representative solutions have been developed:
multicast and P2P. Each of them has limitations when it has to implement
VCR interactions to offer true-VoD services. With multicast delivery
schemes, part of system resources has to be exclusively allocated
in order to implement VCR operations, therefore the initial VoD system
performance is considerably reduced. The P2P technology is able
to decentralize the video delivery process among all the clients. However,
P2P solutions are for video streaming systems in Internet and do
not implement VCR interactivity. Therefore, P2P solutions are not suitable
for true-VoD systems. In this paper, we propose the design of VCR
mechanisms for a P2P multicast delivery scheme. The new mechanisms
coordinate all the clients to implement the VCR operations using multicast
communications. We compared our design with previous schemes
and the results show that our approach is able to reduce the resource
requirements by up to 16%.
