		abstract={Nowadays, digital technology gives a way to access and distribute some    
 
 
 

information in digital formatted easier, one example of multimedia service is    
 
 
 

video. Video as a product from intellectual creation of human, that is product    
 
 
 

mixed between images and sounds, therefore it is essential for a multimedia    
 
 
 

executes process concept that can give copyrighted of distribution and making    
 
 
 

process in digitalization. Pirates or manipulation product problem from illegal    
 
 
 

parties it could be happened because of lost security from its product, so it    
 
 
 

becomes a problem for video provider.    
 
 
 

One way to overcome those problems are using of text encryption process, which    
 
 
 

were done with embedding text in a video with AVI format as input media. By    
 
 
 

using Discrete Cosine Transform (DCT) algorithm compression which result    
 
 
 

image media (video in MPEG-2) as output video, and RSA algorithm as data    
 
 
 

message encryption. These processes were being done with efficiency    
 
 
 

measurement referred to quality embedded images with respect to encode process    
 
 
 

from manipulated digital video data.    
 
 
 

With the production of compressed video from AVI format to MPEG-2 video    
 
 
 

format, the video can analyzing before, it watermarked and preserved the    
 
 
 

authentication of digital video data.}
