Technical Specification: AI-Enhanced Video Coding (MPAI-EVC) – Up-sampling Filter for Video applications (EVC-UFV) V1.0  – in the following also called as EVC-UFV V1.0 or simply EVC-UFV –

  1. Specifies
    1. A procedure to design up-sampling filters for video applications based on super resolution techniques
    2. A procedure to reduce the complexity of the designed up-sampling filter to a specified level of complexity.
  2. Provides the parameters of two specific complexity-reduced up-sampling filters for
    1. Standard definition to high definition
    2. High definition to ultra high definition.

Users are informed that the high definition to ultra high definition up-sampling filter can be used for standard definition to high definition as well with limited performance loss.

The Terms used by EVC-UFV are defined in Table 1. All MPAI Terms are accessible online.

EVC-UFV V1.0 has been developed by the AI-Enhanced Video Coding group of the Requirements Standing Committee. MPAI may decide to develop new versions extending EVC-UFV V1.0 or develop new specifications in the same of related areas.
