Encryption

Encryption uses proprietary software to encrypt each frame.

By encrypting, you are slowing the system down since it is mixing up the ones and zeros in a way that only it can recreate under specific circumstances.

You may think since these frames are now digital, enhancements, changes, and even illegal modifications maybe made.

The encryption is to prevent this kind of abuse of the video product.

However, in speaking with one manufacturer, they had never heard of a court case involving the question of encryption of the material and the authenticity of the original digital material.
