Formula 1 has delayed the launch of its new live streaming service, with no official date for the system being fully operational.
F1's planned to roll out its 'OTT' (over-the-top) stream for this weekend's season-opening Australian Grand Prix, but has instead decided on a testing phase to hone the system.
F1 TV will only be available in countries where the local broadcaster has given up its exclusive digital rights under new or renegotiated deals.
The current list includes the USA, Germany, Austria, Switzerland and much of Latin America. Fans can subscribe to the service for around $100 for the season.
"We will do a stress test/beta test session during the Melbourne weekend with the aim to be fully operational as soon as possible," an F1 spokesperson told Autosport.
"It's a normal process when you develop a new product. It won't be a public test, it will be an internal test.
"We will have people spread in various locations in the world, testing the system and functionalities."
Asked about the likely timing of F1 TV's introduction, the spokesperson said: "As soon as possible. There is not a set deadline."
There is also a plan to introduce the new portable F1 Vision device, which was known as FanVision when it was last used in 2012, for the Spanish Grand Prix on the weekend of May 13.
"We should launch it by the start of the European season," the spokesperson confirmed.
