Can I make a video-stream not downloadable (by using tricks inside the code) [duplicate]

Question

I have used to download any video content from using some programs (like Internet Download Manager (IDM) that has never failed before).

Being a beginner of webdesign I'm wondered if there is a way to protect my video from downloading while it is streaming, or if there is a trick to slip away at least from this Internet Download Manager.

Answer 1

If you are hosting the video on your server/shared server

Place the embedding code in an external JavaScript file. This makes the video file difficult to find. Write this JavaScript by splitting up the location of the video into different variables spread throughout the code, or by referencing variables from other JavaScript files used elsewhere in the web page). This will just make downloading difficult, but not impossible.

Use a streaming server:

These make it almost impossible to download but the cost of signing up with them is generally very high.
Examples of streaming servers:
RealNetworks Managed Application Services (MAS)
Apple Quicktime Streaming Services
Macromedia Communication Server Hosts
