title: Adaptive bitrate streaming
body: <p>I'm newbie of video streaming. I have a question of adaptive bitrate streaming that i can't find the answer on net. I have 100+ videos and each of them have 3 different qualities: 360p, 720p and 1080p. Which mean i need 300+ videos store on my server. </p>
  
  <p>If i use adaptive bitrate streaming solution like Wowza, do i still need to store 3 qualities  of each on my server? Or i just need the most quality video file(1080p) to store on server and Wowza will extract all qualities by itself to viewers?</p>
  
  <p>Thanks for help. </p>
