Technology Overview

Consumers want a high-definition video, at the best possible quality picture, they want to watch it whenever and wherever they choose, they want it delivered seamlessly to screens ranging from the largest monitors to the smallest smart phones, and they want it delivered with no lag, stutter, or digitization. The HEVC/H.265 standard offers the next generation video compression features needed to meet these immediate and rapidly growing needs.

The HEVC Advance patent portfolio includes patents essential to all of the core functionalities of the HEVC/H.265 Standard:

  1. Frame partitioning and sub-partitioning
  2. Intra-picture prediction
  3. Inter-picture prediction
  4. Transforms, scaling, and quantization
  5. In-loop filtering
  6. Entropy coding

Better Quality and Reduced Bandwidth

HEVC/H.265 delivers significant bit rate reductions compared to existing protocols – up to a 50% bit rate improvement over H.264 – providing an optimized transport solution for 4K and higher video resolutions, and supporting images up to 7680 x 4320. HEVC can be adapted for any transport protocol, and is the leading technology for efficiently delivering streaming video in 4K and higher resolutions.

Benefits of HEVC/H.265

 

Higher Resolutions

Supports 4k and higher resolutions for enhanced user experience.

Flexibility

Higher compression allows more content to be available to consumers without modifying existing network and storage infrastructure.

Reduce Expenses

Deliver same content to consumers using fewer resources and lower data consumption.

Speed

Lower bit rates allows faster downloads.
