This paper developed a method for the selective treatment of the underlying video frame, based on the compatibility of the code structure is energetically meaningful structural unit with the requirement of the method of block symmetric encryption algorithm to encrypt the closing streaming video technology-based intra-breeding base of the video frame. This method allows to increase the capacity of the closed channel video data in departmental systems. A methodological framework for the calculation of the bit rate of encoded structural unit of the base of the video frame. Schemes formation bitmap to match the encryption key matrices. Also featuring encryption and decryption scheme is a significant structural unit of the base frame. A comparative analysis of the bitstream encoded structural unit in the bit stream of the original fragment the video. The example of the closed base of the video frame based on the encryption of significant structural units.
