The Digital Video Server (DVS) isspecial equipment used to compress, store and process video and audio data, while MPEG2 is one of the most popular formats.Based on the characteristics of DVS and MPEG2File,the author has proposed aselective encryption algorithm based on Location File, given the encryption renderings by experimentation and analyzed its compression ratio, storage space, quantity of encrypted data, time of encryption and security and other functions in the paper.
