The deal between the two parties will also cover the 2020 Winter Youth Olympic Games in Lausanne.

SPN, an Indian pay television network, has acquired rights across all media platforms.

It does not include the free-to-air rights in Bangladesh, Bhutan, the Maldives, Nepal, Pakistan and Sri Lanka, which have already been granted to the Asia-Pacific Broadcasting Union.

Coverage will now feature on SPN's digital platform, SonyLIV, while the Olympic Channel and other IOC platforms will show highlights and replays of key events.

Both parties have also agreed to work on creating a permanent place for the Olympic Channel within SonyLIV.

"As a dynamic sports and media market, India and the subcontinent is an important strategic region for Olympic broadcasting," said IOC President Thomas Bach.

"The IOC is pleased to be working with Sony Pictures Networks India to collaborate together to bring the best coverage of Tokyo 2020 and the Youth Olympic Games to fans across the region, on their platform of choice, with the aim of inspiring young people to engage with Olympic sports and the Olympic values."

Last year, the Pyeongchang 2018 Winter Olympics were live-streamed on the Olympic Channel across India and the subcontinent.

The IOC said this was a "successful broadcast".

SPN managing director and chief executive N.P Singh said: "As an organisation, we continue to play a leading role in shaping and meeting the entertainment needs of the evolving consumer base across television and digital platforms in India. 

"The Olympic Games is the largest and most prestigious international sports competition in the world with over 200 countries participating. 

"The addition of the Olympic Games Tokyo 2020 broadcast and digital rights complements our portfolio of international sports events and properties."
