Conventional key distribution methods using on Pay-TV system emphasize on the method¡¦s refinement in order to reduce the quantity of the keys distributed over network. This paper brings up the manner using digital watermarking technique to hide the cryptographic keys into routine encrypted video file without any increment of video file size for the economy of network bandwidth. The experimental results show that the proposed method works well in image quality and economical key distribution.
