As per an agreement with the Board of Control for Cricket in India, Nimbus Sports will also distribute internet and mobile rights for the two series worldwide.
''We signed Nimbus up only yesterday and we are now assured that fans of Indian cricket across the world will be able to enjoy exciting cricket in these two series,'' BCCI president Ranbir Singh Mahendra was quoted as saying in a Nimbus press release.
The agreement ensures that fans of Asian and African cricket across the world will be able to access live pictures across various media, that is television, internet and mobile devices.
Two days ago, the BCCI had awarded Prasar Bharti the Indian telecast rights for the two series.
The state broadcaster clinched the deal after offering the BCCI a deal of Rs 7.5 crore per match.
Television house TWI was given the production rights.
India play seven matches against Sri Lanka and five against South Africa.
The Lanka series starts at Nagpur on Oct 25.
