- video encryption system uses 'Line-shear'
techniques to provide secure encryption of colour/monochrome
video recordings with a high level of image obscurity and decoded
image quality.
- optimised for use with VCR video tape recorders in sensitive
security and video distribution applications. It is hardened
against VCR dropout and distortions. It provides reliable, secure
operation and a high quality decoded video image.
- Available in PAL/SECAM or NTSC video versions. Each unit may
operates as either an encoder or decoder and is switch
selectable.
- Provides a smart card system that may be configured by the user
via a serial interface connected to an IBM PC. The smart card
contains coding information that prevents decoding by any other
unit not configured in an identical manner. Tapelock may
optionally be used without the smart card at a reduced security
level.
- Provides 4 levels of security key coding. All these keys and
coding systems must match for the decoder to be able to decode an
encoded tape. 1: The primary keys are unique to each group of
users and are burned into the hardware. These keys are factory
set and are different for all groups of users. 2: The 256-bit
user keys may be programmed by the user via the serial interface.
3: The 8-bit Dip switch code may be set via combinations of
switches within the unit. 4: The smart card coding system
configured via the serial interface.
- Provides features to aid in system setup, fault diagnostics and
system confidence. Video is passed through during power loss. The
decoder will go into clear mode if it detects that the video is
not a valid encrypted signal. The decoder provides optional
indication of correct operation with a small on screen flashing
square. A flashing RED/GREEN indicator gives operational
information.
- Compact, rugged and has low power consumption. |
