DCTIF: DCT-derived interpolation filter.

  • DIS: Draft international standard – the second formal ballot stage of the approval process in ISO/IEC.

  • DF: Deblocking filter.

  • DRC: Dynamic resolution conversion (synonymous with ARC).

  • DT: Decoding time.

  • EPB: Emulation prevention byte (as in the emulation_prevention_byte syntax element).

  • EL: Enhancement layer.

  • EOTF: Electro-optical transfer function

  • ET: Encoding time.

  • GRP: Generalized residual prediction.

  • HE: High efficiency – a set of coding capabilities designed for enhanced compression performance (contrast with LC). Often loosely associated with RA.

  • HEVC: High Efficiency Video Coding – the video coding standardization initiative under way in the JCT-VC.

  • HLS: High-level syntax.

  • HM: HEVC Test Model – a video coding design containing selected coding tools that constitutes our draft standard design – now also used especially in reference to the (non-normative) encoder algorithms (see WD and TM).

  • IBC: Intra block copy – a technique similar to integer-displacement motion compensation, but applied relative to previously decoded regions of the same picture rather than relative to previously decoded different pictures.

  • IBDI: Internal bit-depth increase – a technique by which lower bit depth (8 bits per sample) source video is encoded using higher bit depth signal processing, ordinarily including higher bit depth reference picture storage (ordinarily 12 bits per sample).
