As the new voting system gives equal weight to jury and televoting results, a national jury result cannot be used as backup result for the televoting or vice versa.Therefore, if a country cannot deliver a valid televoting/jury result, a substitute result is calculated by the jury/televoting result of a pre-selected group of countries approved by the contest's Reference Group.After viewers have cast their votes, the results of each professional jury are presented, with countries receiving 1-8 and 10 points being displayed on-screen instead of 1-7, which had been the case since 2006, and the national spokesperson announcing only the country to which they award 12 points.After the results of the professional juries are presented, the televoting points from all participating countries are combined, providing one score for each song.
This was Ukraine's second win and its first since 2004.
Portugal withdrew, largely due to their national broadcaster's insufficient promotion of their music-based media, while Romania had originally planned to participate, but was forced to withdraw due to repeated non-payment of debts by their national broadcaster to the European Broadcasting Union (EBU).
The contest was also the first to implement a voting system change since 1975: each country's professional jury points were announced largely as before, while the results of each national televote were combined and announced in reverse order.
Discussions were held in 2014 between the EBU and the Asia-Pacific Broadcasting Union (ABU) regarding the inclusion of a guest performance from the ABU TV Song Festival at the contest.
The EBU confirmed on 16 July 2015 that they are looking into the possibility of the proposal, which was discussed at the ABU General Assembly in 2014.
