G.hn is the marketing name for ITU-T Recommendation definine, the next generation home AV network standard for transferring Internet Protocol (IP) content across existing coax cables, phone lines, and AC power lines in the home. The main goal of G.hn is to enable consumers to access, store, and share a wide variety of content around the home without having to install new wiring. This includes broadband data, HD programs, video-on-demand (VOD), multi-room HD DVR recordings, voice over IP (VoIP), and streaming of HD video, music, and photos.

G.hn Recommendation is composed of three core components:

• ITU Recommendation G.9960 – Physical Layer
• ITU Recommendation G.9961 – Data Link Layer
• ITU Recommendation G.9972 – Coexistence protocol

This universal standard delivers the ultimate in performance (up to 1 Gbps) with the highest level of interconnectivity among devices in the home. It is also an excellent technology for enabling access in MDU, Hospitality, Broadband Access, and Smart Grid applications.

CopperGate, a wholly-owned subsidiary of Sigma Designs, is one of the leading proponents of G.hn and is active in the G.hn working groups. CopperGate is considered one of the leaders in G.hn due to their extensive and proven expertise in deploying HomePNA^® and HomePlug^® AV solutions that use existing coax, phone lines, and AC power lines in the home.

Sigma Designs will deliver G.hn chipsets with complete backward compatibility to HomePNA^®. Every service provider who uses G.hn will have a smooth migration from legacy standards to the next generation.
