    I'm not quite sure this is an Android related question. – Lie Ryan Nov 01 '12 at 08:06
  • Miracast was introduced in Android 4.2, where else have you seen it? – est Nov 01 '12 at 08:58
  • It is like asking about USB cable or GSM antenna or LiON battery, if the question are not Android-specific issue of the technology, they are generally considered off topic. Although the enforcement for these specific kind of questions have been quite lax, and I've been guilty answering a few such questions in the past. – Lie Ryan Nov 01 '12 at 09:32

    This article discusses the differences. – THelper Nov 01 '12 at 11:35
  • May I/we edit the question to address the user experience and use of these as a way to use an external display given an Android device? That is what I am after and is Android-specific. – user29020 Sep 12 '14 at 15:20
  • @user29020 ok go ahead. It's closed anyway – est Sep 18 '14 at 14:40

okay since no one is willing to answer this question, I figured something out myself.

Here's the key points:

DLNA:

  • TCP level, HTTP+SOAP interface based on UPnP technology
  • pull & push media contents
  • remote control play/pause/seek

Miracast:

  • transport layer protocol
  • AP makes two device handshake, then two device communicate directly via wireless
  • not only stream video/audio contents, but also mirro device screens from one to another.
