The national football championship has been a money-spinner for the VFF since 2004, when Vietnam Television paid VND4 billion ($200,000) to broadcast the V-League.
AVG, licenced to operate a satellite and digital television service, plans to launch a 70-channel TV package late next year.
The cable TV provider, a member of the An Vien Group, was established in 2008 with a charter capital of VND1.8 trillion ($90 million).
It's the first ever TV copyright to be signed between a private television company and a sports federation in Viet Nam.
AVG also signed a 20-year TV rights contract with the Vietnam Athletics Federation (VAF) last week.
However, a VAF representative refused to declare how much the deal was worth, but said AVG would broadcast five to seven national tournaments each year.
