H.265/HEVC

H.265/HEVC

H.265, also known as HEVC (High Efficiency Video Coding), is the latest video codec standard. The first version of the standard was ratified in April 2013.

H.265 achieves up to 2X bandwidth savings over previous generation H.264/MPEG-4 AVC based technologies. Alternately, H.265 encoded streams can offer higher quality than H.264 streams encoded at the same bit-rate. The H.265 standard supports UHD resolutions, including 4K and 8K, and format range extensions (RExt) for higher bit depths and up to 4:4:4 chroma sub sampling.

These advantages are a key factor driving the adoption of the H.265 codec across the Digital Media Creation, Distribution and Consumption chain. Applications include

  • Film Post Production, Non Linear Editing (NLE)
  • Mezzanine Formats, Storage
  • Contribution, Live Broadcast
  • Content Repurposing
  • VOD, OTT and Mobile Delivery
  • Monitoring, Integrated Receiver / Decoders (IRDs) and Studio Playback
  • Mobile Playback
