MIVO.TV Network Analysis

While my browser was playing the video streaming (tru flash-plugin) from mivo.tv,  a “netstat -t” revealed high traffic as below:

tcp        0      0 ESTABLISHED

After googling this “macromedia-fcs” I found:

TCP & UDP Port 1935 (Macromedia-fcs)
Technical description for port 1935:

The RTMP (Real Time Messaging Protocol) service associated with the computer port 1935 is a plain protocol utilized by the Adobe Macromedia Flash application. This proprietary service allows for the streaming of data, video and audio using an active Internet connection among a Flash Server and its associated player. This port supports the three variations of the RTMP service.

The communication port 1935 along with the TCP protocol is used for the delivery of encapsulated RTMPT that traverses firewall applications using HTTPS (secured) connections. The design of this protocol was intended to provide a persistent service for the Flash technology along with other programs like Adobe LiveCycle Data Services ES.

The raw TCP RTMP protocol uses one persistent connection for allowing the implementation of real time communication and smooth delivery of multimedia contents.

The protocol running on the port 1935 achieves this quality of transmission without affecting its ability to send bigger chunks of information including the fragmentation of data.

Digging deeper to the HTML code, I found a port in Javascript like this:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
               width=”610″ height=”878″ id=”MivoTV” align=”top”>’
But why it doesn’t work if I open the URL directly and put some random number at the end [0..99999]?

<object '
