With the fast expansion of a variety of multimedia technologies, further and more multimedia statistics are produced and transmitted in the fields like military, medical and for further commercial field which may have some susceptible information that is not to be supposed to be seen or accessed by or may only be shown partially to the common users. Therefore, security and privacy has turn out to be significant phase. Over the last few years numerous encryption algorithms are introduced to secure and protect the video during transmission. Along with that many efficient multimedia encryption schemes are introduced and real world is using those techniques. In this paper, various techniques are observed described showing encryption methods and video transmission techniques have been studied.
