Definitions
Video adaptation refers to the process of adapting video, for a specific context, in terms of coding parameters such as frame rate, spatial resolution, color or bitrate. It can also be referred to as homogeneous transcoding where a video bitstream is transcoded between the same video standard/codec. Video encryption is used in many video transmission applications to ensure that only authorized receivers can access the media. Reasons for encryption include security, privacy, business reasons (only subscribers who have paid should be able to view), age restrictions, etc. Video authentication is a process to establish the fidelity of a digital video. A video authentication system ensures the integrity of digital video, and verifies that the video taken into use has not been doctored.

In the last decade, the number of handheld devices capable of...
