US10904595B2 System and method for just in time embedded watermarking of streaming proxies

Further, the system automatically supports adaptive bit rate optimization by providing interoperability with multiple potential adaptive bit rates requestable by the content player device. The system watermarks the requested content segment in real-time during the streaming of the content by causing burn-in of the user-specific watermark into the streaming content.
