Homeplug® AV is the latest, highest performing generation of technology from the Homeplug Powerline Alliance. It delivers high-quality network connections over existing powerlines within the home tailored for transmitting multiple high-bandwidth audio-video entertainment streams.

Homeplug® AV employs advanced physical layer (PHY) and medium access control (MAC) technologies that provide a 200 Mbps class powerline network for video, audio and data. The PHY layer utilizes this 200 Mbps channel rate to provide a 150 Mbps information rate with robust, near-capacity communications over noisy powerline channels. The MAC Layer is designed to be highly efficient; supporting both Time Domain Multiple Access (TDMA) and Carrier Sense Multiple Access (CSMA) based access with AC line cycle synchronization. The TDMA access provides quality of service (QoS) guarantees including guaranteed bandwidth reservation, high reliability, and tight control of latency and jitter. The CSMA access provides four priority levels. AC line cycle synchronization provides superior channel adaptation in the face of common line cycle-synchronized noise.

Homeplug® AV offers tight security based on 128-bit AES and makes provision for dynamic (automatic) change of the encryption keys and for several different user experiences in setting up security and admitting stations to the network. The design allows a station to participate in multiple AV networks. Homeplug® AV offers several mandatory and optional co-existence modes enabling multi-network operation, hidden node service, and broadband over powerline (BPL) co-existence.
