Certified Output Protection Protocol

Definition of Certified Output Protection Protocol

Certified Output Protection Protocol (COPP) is a technology standard used in Windows operating systems to ensure secure and encrypted communication between a computer’s graphics processor and a compatible display device. It is designed to prevent unauthorized access and copying of copyrighted digital content. COPP supports high-bandwidth digital content protection (HDCP) to secure digital transmissions over digital visual interfaces (DVI) and high-definition multimedia interfaces (HDMI).


The phonetic pronunciation of “Certified Output Protection Protocol” is:- Certified: sər’tɪfaɪd- Output: ‘aʊtˌpʊt – Protection: prə’tɛkʃən- Protocol: ‘proʊtəˌkɒl

Key Takeaways

  1. Certified Output Protection Protocol (COPP) is a technology framework that helps protect digital content by managing and enforcing digital rights management (DRM) policies on output devices.
  2. COPP works by requiring device manufacturers to implement hardware and software components that adhere to specific security standards, ensuring secure and encrypted transmission of content between devices.
  3. By using COPP, content creators and distributers can be confident that their copyrighted material is protected, which can in turn promote the development and distribution of high-quality digital media.

Importance of Certified Output Protection Protocol

The technology term Certified Output Protection Protocol (COPP) is important because it plays a critical role in maintaining the security and integrity of digital content, specifically in audio and video distribution.

COPP safeguards against unauthorized copying and distribution by ensuring that content is only transmitted to authorized display devices, which helps protect the rights of content owners and producers.

By establishing a secure handshake between a source device (e.g., a computer) and a receiving device (e.g., a monitor or TV), the protocol prevents malicious interception or manipulation of the content, thereby mitigating risks of piracy and maintaining a high value for digital media.

Overall, COPP contributes significantly to the growth and sustainability of the digital content industry.


The Certified Output Protection Protocol (COPP) is designed to address the concerns related to the unauthorized distribution and duplication of digital content, particularly high-quality audio and video. With the rapid evolution of digital technology, content creators and distributors are constantly seeking ways to protect their intellectual property while still offering exceptional experiences for their audience.

The primary purpose of COPP is to provide a robust and secure method for transmitting protected content between a playback device and an output display device, ensuring that only authorized consumers have access to the material. In practical terms, the implementation of COPP involves the cooperation of both hardware and software components, ensuring that the entire ecosystem operates with heightened security.

By incorporating this protocol within playback devices, display units, and media software, content owners and distributors can effectively enforce digital rights management (DRM) policies. As a result, copyrighted content is prevented from being intercepted or copied during the transmission process between devices.

This safeguard ultimately helps maintain the value of the original content and fosters a fair distribution environment, benefiting both creators and consumers in the rapidly evolving digital market.

Examples of Certified Output Protection Protocol

The Certified Output Protection Protocol (COPP) is a digital rights management (DRM) technology that helps ensure the secure and authorized delivery of copyrighted digital audio and video content. It is designed to prevent unauthorized users from copying or redistributing digital content by establishing a secure connection between the output device and the receiving device. Here are three real-world examples where COPP is implemented:

Blu-ray Disc Players: Blu-ray disc players use the COPP technology to protect digital content such as high-definition videos and movies. When the player connects to an HDTV or any display device, it establishes a secure pathway using COPP, ensuring that the video content cannot be copied or intercepted by unauthorized devices.

Streaming Services: Streaming services like Netflix, Hulu, and Amazon Prime Video implement COPP to ensure secure delivery of copyrighted video content to users’ devices, including computers, smartphones, and smart TVs. By using COPP, these services protect their video content from unauthorized copying and redistribution, helping the content creators and distributors maintain the value of their copyrighted material.

PC-based Video Playback Applications: Some PC-based video playback applications, such as Windows Media Player, VLC Media Player, or CyberLink PowerDVD, use the COPP technology to secure the playback of copyrighted digital content. When these applications play protected content, they establish a secure connection to the output device, such as a monitor or TV, ensuring that the content remains protected from unauthorized copying or redistribution.

FAQ: Certified Output Protection Protocol

1. What is Certified Output Protection Protocol?

Certified Output Protection Protocol (COPP) is a technology used by digital media players to ensure the safe transmission of copyrighted content from the media player to an external display. It helps prevent unauthorized copying and distribution of copyrighted material by securing the connection between devices.

2. How does Certified Output Protection Protocol work?

COPP works by establishing a secure communication channel between the media player and the display device. This secure channel allows the transmission of encrypted content that can only be decrypted by an authorized display device. This process ensures that the content remains protected and unauthorized copying is prevented.

3. What are the advantages of using Certified Output Protection Protocol?

The main advantage of using COPP is that it enables the secure distribution of high-quality digital media content while minimizing the risk of unauthorized copying and distribution. This helps to support the growth of digital content distribution platforms by ensuring that copyrighted material remains protected and creators receive due compensation for their work.

4. Does my device need to support Certified Output Protection Protocol?

If you want to enjoy protected digital media content, such as high-definition movies and TV shows, your media player and display device should both support Certified Output Protection Protocol. This will ensure that the content is securely transmitted and you can fully experience the high-quality media content as intended.

5. How do I know if my devices support Certified Output Protection Protocol?

To determine if your devices support COPP, you can refer to the specifications or user manual of the media player and display device. You can also check the manufacturer’s website for information about their supported technologies or contact their customer support for further assistance.
