HSV may refer to:
HSV is a television station in Melbourne. It is part of the Seven Network, one of the three main commercial television networks in Australia, and its first and oldest station, having been launched in time for the 1956 Summer Olympic Games in Melbourne. HSV-7 is the home of the AFL coverage.
The HSV building (also known as 'Broadcast Centre Melbourne') is the network's operations hub, where the Master Control Room is located for all metropolitan and regional feeds to be controlled. Programming line-up, advertisement output, feed switching, time zone monitoring and national transmission output are delivered here. All Seven Network owned and operated studios have their LIVE signals relayed here (e.g.) ATN's output is fed to HSV and then transmitted via satellite or fibre optic to the towers around metropolitan Sydney, etc.
