Hi Venkat.
It sounds like you are using unprotected files. Can you share what type of media you are using? I’m not aware of any simple way to apply HDCP to non-protected content so it will be useful to understand if that is what you are dealing with.
As Michael pointed out, even with HDCP, it is possible to get an analog copy of that signal using a device such as the HDFury so it may be important to physically secure the channel as well depending on your circumstances.
