Below is a detailed guide on US HDMI 2.2 certification, hoping to help you fully understand the latest requirements and compliance path for this technical specification.

The race for the new generation of audio-visual standards has begun. HDMI 2.2 certification is not only a technical threshold but also a ticket for products to access the high-end market.

HDMI 2.2 Core Technological Innovations:

The HDMI 2.2 specification was officially released at the 2025 CES exhibition, representing a revolutionary leap in audiovisual transmission technology.

1.Doubled Bandwidth: Maximum bandwidth increased from HDMI 2.1's 48Gbps to 96Gbps. This improvement is achieved through a new generation of Fixed Rate Link (FRL) technology, laying the foundation for ultra-high definition content transmission.

2.Ultra High Resolution Support: Now capable of supporting display outputs up to 12K@120Hz or 16K@60Hz, while also supporting ultra-high refresh rate formats like 4K@240Hz.

3.Latency Indication Protocol (LIP): This is an important new function introduced in HDMI 2.2, designed to solve audio-video synchronization issues in multi-device environments. LIP allows devices to share latency information and automatically adjust, significantly enhancing home theater and gaming experiences.

  Core HDMI 2.2 Certification Process:

1.Member Registration & Qualification Audit (Approx. 1-2 weeks):

Companies must register on the HDMI Forum website to become an "Adopter" and sign the《HDMI 2.x Adopter Agreement》. Membership types include:

·Standard Member: Annual fee $10,000 USD, no production limit.

·Low Volume Member: Annual fee $5,000 USD, applicable to companies with annual production not exceeding 5,000 units.

This stage also requires simultaneous registration for HDCP Membership (High-bandwidth Digital Content Protection protocol) and submission of business license and other qualification documents.

2.Pre-testing & Rectification (Approx. 2-4 weeks, Highly Recommended):

Before submitting formal testing, it is highly recommended to conduct "Pre-testing" at an Authorized Test Center (ATC), which can significantly improve the first-pass rate of formal testing. Main checks include:

·Electrical Performance: Such as signal integrity (eye diagram analysis, clock jitter ≤0.15UI), impedance matching.

·Protocol Compatibility: Such as EDID communication, HDCP 2.3 encryption verification.

·Interoperability: Cross-testing with mainstream brand devices (e.g., Sony, LG, Samsung).

If issues are found after pre-testing, technical rectification is required.

3.Submit Formal Testing (Approx. 1-3 weeks):

This is the core link to verify product compliance.

·Sample Requirements: At least 2 near-production-ready prototype units need to be prepared (one with HDCP disabled for protocol testing, one with HDCP enabled for functional verification).

·Test Content: Covers signal integrity, protocol consistency (e.g., CEC control commands), video/audio performance (e.g., support for 8K@60Hz, HDR10+, eARC), etc. For devices supporting HDMI 2.2, mandatory test items such as FRL protocol connection success rate verification (failure rate ≤1%) must also be passed.

·Test Cycle: Basic products (e.g., cables) approximately 5-10 working days; complex products (e.g., 8K TVs) may extend to 15 days.

4.Review & Certification Issuance (Approx. 1 week):

After testing passes, the laboratory submits the report to the HDMI Forum for review, with a review cycle of about 3 working days. Upon passing, the HDMI certificate (containing a unique certification number) and trademark usage license are obtained.

5.Compliant Production & Market Surveillance (Ongoing):

After obtaining certification, companies must fulfill ongoing obligations:

·Pay Royalties: Paid per unit sold, usually $0.15/unit; if the HDMI logo is marked on the product, the fee can be reduced to $0.05/unit.

·Comply with Trademark Specifications: For example, the HDMI logo height must not be less than 3mm.

·Respond to Market Spot Checks: The HDMI Forum conducts market surveillance. Improper use of trademarks may lead to goods detention or membership cancellation.

  Ultra96 Cable Certification Program:

The HDMI 2.2 specification introduces the brand-new Ultra96 HDMI Cable, an essential component supporting the 96Gbps bandwidth.

1.Mandatory Certification: The Ultra96 HDMI Cable and Ultra High Speed HDMI Cable are both part of the Ultra HDMI Cable Certification Program. This is a mandatory certification program aimed at ensuring only high-quality, tested, certified, and compliant cables enter the market.

2.Certification Label: All Ultra96 HDMI Cable models must pass certification testing at an HDMI Forum Authorized Test Center. After certification, each package of the cable should have the Ultra96 HDMI Cable certification label affixed, facilitating consumers to verify the product's certification status.

3.Ongoing Compliance Audit: To ensure Ultra96 HDMI Cables consistently comply with the specification throughout their product lifecycle, the HDMI Forum will purchase cables from the market for testing. If a cable fails the test, the Adopter must correct the manufacturing issue, otherwise they will be unable to order certification labels for that cable.

  HDMI 2.2 Certification Costs & Optimization Strategies:

1.Core Cost Composition:

·Membership Annual Fee: $5,000-$10,000 USD

·Testing Fees: Basic equipment $3,000-$5,000 USD, HDMI 2.2 equipment starting from $10,000 USD

·Royalties: Paid per unit sold (No logo $0.15/unit, With logo $0.05/unit)

·HDCP Encryption Fee: Supporting content protection requires an additional $1,000-$5,000 USD

2.Cost Optimization Strategies:

·Make Good Use of Pre-testing: Although not mandatory, it can effectively avoid cycle extensions and additional costs caused by formal test failures.

·Utilize "Family Models": If subsequent products only change casing or color, with no major changes to hardware and firmware, certification can be quickly extended via "Family Models" without repeating the full set of tests.

·Modular Design: During the initial product design phase, prioritize selecting chips or interface modules that have already passed HDMI certification, which can simplify the testing process.

  Important Reminders & Risk Avoidance:

1.Mandatory Requirement: Starting in 2025, the HDMI 2.2 specification has become a mandatory standard. Product certifications supporting only older specifications will become invalid and cannot be sold on the market.

2.Trademark Use Compliance: The HDMI trademark is registered with US Customs. Using the HDMI mark without certification will result in goods being detained, fines (up to 30% of the goods' value), and forced removal from e-commerce platforms.

3.Certificate Maintenance: The validity of the HDMI certification certificate is conditional. Companies must ensure the certificate remains valid.
