It is the use of existing electrical cables to transport data, and it has been around for a very long time. Power utilities have been using this technology for many years to send or receive data on the power grid using the existing infrastructure.

Abstract
Thanks to the technological development, the production of multimedia content is no longer restricted to content providers. End-users communities are enabled to efficiently share, distribute, manage, and consume audio-visual contents. In this context, community networks are expected to play a central role. This kind of networks can be understood as the sum of all networks that interconnect devices in the homes, and the homes in a neighbourhood. They can use diversity of technologies, and among all of them, PLC (power line communication) is a very good alternative. In order to provide community networks with proper video services an appropriate middleware support is required to glue together the services and the infrastructures. In this respect, P2P (peer-to-peer) technology is a very good candidate to achieve this objective. On the other hand, there are several aspects of the PLC medium that make it difficult to share resources fairly but they can be solved using P2P technology. In this work, different proposal to provide VoD services using P2P technology are reviewed.
