• HDCP creates a secure handshake between current devices, such as a streaming box and a TV.
• When you connect two HDCP-compliant devices, they exchange a series of encrypted keys to confirm they are authorised to receive and display the content.
• The data is encrypted as it travels between the devices once this handshake is successful. It prevents any unauthorised interception or duplication.
• If a device in the chain isn’t HDCP-compliant, the handshake fails.
• This can result in a black screen, downgraded resolution, or even the inability to play the content altogether.
• This strict process ensures that the premium content remains protected by allowing creators to control how their work is distributed.
• HDCP compliance guarantees that the media they stream, play, or watch retains its intended quality for consumers.
• It also means that the security changes to keep up with new technology.

HDCP Compliance Across Devices

HDCP compliance ensures seamless playback of protected content across devices by safeguarding high-definition media from unauthorised copying.

For HDCP to work, every device in your setup—from your streaming box or Blu-ray player to your TV or monitor—must be HDCP-compliant.

When you connect HDCP-enabled devices, they establish a secure handshake, confirming their authorisation to receive and display the content.

If even one device in the chain isn’t compliant, the handshake fails. This can result in a black screen, reduced resolution, or the inability to play the content altogether.
