Dolby Vision empowers visual creative to add greater  depth, incredible contrast, and more colors than you  dreamed possible to the movies, TV shows, and  games you love.

Dolby Atmos has reinvented how entertainment is  created and experienced, allowing creative everywhere  to place each sound exactly where they want it to go,  for a more realistic and immersive audio experience.

MEMC stands for Motion Estimation, Motion  Compensation. The technology works by inserting  frames in the middle of two frames of a footage to  increase the total number of frames in the same scene.  In simple words, this makes the footage smoother.
