All Seven Network owned and operated studios had their live signals relayed there: for instance, ATN's output was fed to HSV and then transmitted via satellite or fibre optics to towers around metropolitan Sydney.

These two newspapers gave rise to the call sign HSV (the 'V' stands for Victoria, as is the normal protocol for television call signs to have the third letter indicate the state where the station is licensed, although for publicity purposes HSV was said to stand for Herald Sun Vision just as sister station ATN became the Australian Television Network rather than New South Wales).

It was called the Channel 7 Teletheatre and connected to the station's main Dorcas Street studios in South Melbourne by multiple microwave links.

The teletheatre opened with a major live show featuring the US entertainer Bob Crosby and his band and the British comedian Jimmy Edwards, among others.

This station commissioned many of Australian TV's earliest and longest-running courtroom and police procedural dramatic series such as Crawford's Consider Your Verdict and Homicide.

One of the longest-serving station and general managers during the transformative years into international satellite links and color transmissions was Ron Casey.

By the late 1960s, Channel 7 was demonstrating PAL color TV to crowds visiting the annual Royal Melbourne Show.

In late 1987, the government introduced cross-media ownership laws which forced Fairfax to choose between its print and broadcast operations.

It chose print, and HSV-7 was sold to Christopher Skase's Qintex, which already owned Seven stations in Sydney, Adelaide and Perth.

[citation needed] Skase pledged to revitalize the channel and its programs, and to return it to its prior success among Melbourne viewers.

HSV remained there until March 2002 when news, current affairs and sport shows were moved to new headquarters at Docklands and the Dorcas Street Studios were closed.

The building is used as the transmission control centre for Seven's owned-and-operated stations in Melbourne, Sydney, Brisbane, Adelaide, Perth and regional areas of Queensland.
