luminance is the photometric brightness of an object (in units of cd/m 2), taking into account the wavelength-dependent sensitivity of the human eye (the photopic curve); relative luminance is the luminance relative to a white level, used in a color-space encoding; luma is the encoded video brightness signal, i.e., similar to the signal voltage ...
Initially, 4:1:1 chroma subsampling of the DV format was not considered to be broadcast quality and was only acceptable for low-end and consumer applications. [ 3 ] [ 4 ] However, DV -based formats (some of which use 4:1:1 chroma subsampling) have been used professionally in electronic news gathering and in playout servers.
On HDR10 displays that have lower color volume than the HDR10 content (for example lower peak brightness capability), the HDR10 metadata gives information to help adjust the content. [6] However, the metadata is static (remain the same for the entire video) and does not tell how the content should be adjusted.
Luma is the weighted sum of gamma-compressed R′G′B′ components of a color video—the prime symbols ′ denote gamma compression. The word was proposed to prevent confusion between luma as implemented in video engineering and relative luminance as used in color science (i.e. as defined by CIE ).
In Audio, the term high dynamic range means there is a lot of variation in the levels of the sound. Here, the dynamic range refers to the range between the highest volume and lowest volume of the sound. XDR (audio) is used to provide higher-quality audio when using microphone sound systems or recording onto cassette tapes.
