As IPL is not national importance, the tv rights went to sky price and bilateral series is national importance none of the broadcasters going for their rights (ex: WI rights even though india touring to that country). Going forward pvt broadcasters will not give any importance to bilateral series or other country rights, as india matches will shown in DD and Indian viewers not interested in other country matches.
The only way to solve this is , pvt broadcaster start a free channel in DD free dish and telecast the indian matches in that channel rather than sharing it to DD sports, so that pvt broadcaster will get full profit for the price they spent on rights
