The professional CCIR 601 digital video format also uses Y′CbCr at the common chroma subsampling rate of 4:2:2, primarily for compatibility with previous analog video standards. This stream can be easily mixed into any output format needed. Y′UV is not an absolute color space. It is a way of encoding RGB information, and the actual color ...
Pixel formats used in Y'CbCr can be referred to as YUV too, for example yuv420p, yuvj420p and many others. In a similar vein, the term luminance and the symbol Y are often used erroneously to refer to luma, which is denoted with the symbol Y'. The luma (Y') of video engineering deviates from the luminance (Y) of color science (as defined by CIE).
Ideographic Description Characters is a Unicode block containing graphic characters used for describing CJK ideographs.They are used in Ideographic Description Sequences (IDS) to provide a description of an ideograph, in terms of what other ideographs make it up and how they are laid out relative to one another. [3]
Depending on subsampling, the formats can largely be described as 4:4:4, 4:2:2, and 4:2:0p. The apostrophe after the Y is often omitted, as is the "p" (for planar) after YUV420p. In terms of actual file formats, 4:2:0 is the most common, as the data is more reduced, and the file extension is usually ".YUV".
The tool is usually useful for entering special characters. [1] It can be opened via the command-line interface or Run command dialog using the 'charmap' command.. The "Advanced view" check box can be used to inspect the character sets in a font according to different encodings (), including Unicode code ranges, to locate particular characters by their Unicode code point and to search for ...
In the table below, the column "ISO 8859-1" shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.
In the film and graphics industries, 3D lookup tables (3D LUTs) are used for color grading and for mapping one color space to another. They are commonly used to calculate preview colors for a monitor or digital projector of how an image will be reproduced on another display device, typically the final digitally projected image or release print ...
A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form. The x must be lowercase in XML documents. The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the ...
