Peter Oberois claims he has a brand new invention in online Video transmission.

Question

Peter Oberois claims he has a brand new invention in online Video transmission. A Web browser requests a multimedia file via HTTP non-persistent connection. The Web server sends the presentation description of the file. The browser activates the appropriate Media Player based on the file extension. The Media Player requests video file from the Streaming Media Server via a non-HTTP protocol. The Streaming Media Server provides data via constant bit rate video transmission. Client video reception suffers network-added delay, and variability of packet delays within the same packet stream due to normal Internet connection characteristics. Amazingly, Peter shows to the world that the media players render smooth video without delay and jitter just like a DVD playing in the local machine. Which of the following is correct?

Peter has a new invention but he described it wrong.

Peter has little knowledge about anything in online Video transmission because a
     Media Player cannot request a video file from the Streaming Media Server via a non-
     HTTP protocol.

Peter’s claim is valid. He is a new inventor in online Video transmission.

Peter Oberois’s claim is bogus. What he claims is already available.

Peter’s demonstration worked because he just used non-persistent HTTP connection.  
      It would fail if a persistent HTTP connection were used.

Explanation / Answer

Peter has little knowledge about anything in online Video transmission because a Media Player cannot request a video file from the Streaming Media Server via a non HTTP protocol.

These streaming servers worked in conjunction with traditional HTTP servers so that when a viewer clicked a link on the HTTP server, it initiated a connection between the streaming server and the player that persisted until the viewer stopped watching. Because of this connection, these protocols are considered “stateful,” as compared to HTTP, which is stateless and has no connection between server and player.
