title: content-type = video/abst
body: <p><img src="https://i.stack.imgur.com/dvL3m.jpg" alt="Capture of a HTTP trace containing Live TV stream"></p>
  
  <p>In the live TV over HTTP capture, I see the HTTP traffic carrying the 'video/abst' payload. I kind of googled it, but did not find any specific details. </p>
  
  <p>Can someone please explain what this content is and why it is used? </p>
  
  <p>Thanks. </p>
