Video & Multimedia Expert Witness Services

Video & Multimedia Expert Witness Services

DVI Communications provides technical expert witness services in litigation involving video compression standards, streaming protocols, and multimedia patent pool licensing. Our experts bring direct engineering experience with video codec technology to patent, trade secret, and product disputes involving video and multimedia systems.

Why Video & Multimedia Litigation Requires Codec-Specific Expertise

Video and multimedia disputes turn on specific technical questions: how compression standards such as H.264/AVC, H.265/HEVC, AV1, and VVC actually encode and decode video, whether an accused product or service implements a claimed codec feature in hardware, software, or both, and how patent pool structures (such as those administered by MPEG LA, Access Advance, or Sisvel) map to essentiality and licensing obligations. Adaptive streaming protocols such as DASH and HLS add another layer of technical complexity around how content is delivered and adapted.

Case Types We Support

Patent Infringement & Essentiality

Technical analysis of whether accused devices, encoders, decoders, or streaming platforms implement claimed video codec or streaming features, and whether asserted patents are essential to relevant compression or streaming standards.

Patent Pool Licensing Disputes

Support for disputes involving multimedia patent pool structures, where essentiality determinations and royalty allocation depend on specific codec implementation and pool membership terms.

Product Malfunction & Performance Disputes

Technical analysis of video quality, encoding, or streaming performance issues, distinguishing genuine defects from network, device, or content-delivery factors.

Technical Specialties

Our experts’ backgrounds span video compression standards (H.264/AVC, H.265/HEVC, AV1, VVC), hardware and software codec implementation, adaptive bitrate streaming protocols, and multimedia patent pool licensing structures — documented through decades of industry practice and prior expert testimony.

Frequently Asked Questions

How is a video codec expert witness different from a general software expert?

Video codec disputes require specific familiarity with compression standard specifications and their hardware/software implementation, not just general software or media engineering experience.

What case types commonly involve video and multimedia technical disputes?

Patent infringement and essentiality disputes tied to video compression or streaming standards, patent pool licensing disputes, and product performance cases involving video quality or streaming delivery.

How Engagement Typically Works

An early step is confirming which codec standard, profile, and implementation layer (hardware versus software) govern the dispute. From there, the process follows the same structure as other technical patent and product litigation: detailed technical analysis, a written expert report, and testimony prepared to withstand challenges to both the technical conclusions and the standard at issue.

What Makes a Video & Multimedia Technical Analysis Credible

Video codec architecture spans encoding, decoding, and delivery layers, and a credible analysis has to be specific about which layer and which standard actually governs the claimed functionality, rather than treating “video technology” as a single undifferentiated category.

When to Engage

Engaging a technical expert early allows the analysis to account for the specific codec standard, implementation, and licensing context at issue from the outset, rather than retrofitting a theory later.
