I was surprised upon finding this today, as I had no idea it was planned to be released as early as it was!
Dragon Ball Super EP 1 came out yesterday! It is in japanese obviously, but it has been subbed well for english.
As of now with the limited information we have about what is going on it is hard to tell exactly when in time this is taking place. It is stated definitely after the Buu saga but it appears to be before Battle of Gods. This would make sense except for the fact that Beerus is awake and destroying planets and that would be a major plothole due to the fact Beerus was supposed to be asleep durring that time period.
So it's pretty hard to tell how this ties in with the movies right now, but Beerus and Whis are main characters they just don't seem to have met Goku or Vegeta as of yet. I read online that Toriyama is planning on retelling the whole battle of God story and the movies will be non-cannon. I don't really know if that is the truth but it is what I read.
ANYWAYS, I will link it here so you guys can watch if you have not already. It is planned to come out every Sunday morning in japan- with english subtitles following hours later.
Watch it here
