RY

Ry or RY may mean:

YUV

YUV is a color space typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, thereby typically enabling transmission errors or compression artifacts to be more efficiently masked by the human perception than using a "direct" RGB-representation. Other color spaces have similar properties, and the main reason to implement or investigate properties of Y'UV would be for interfacing with analog or digital television or photographic equipment that conforms to certain Y'UV standards.

The scope of the terms Y'UV, YUV, YCbCr, YPbPr, etc., is sometimes ambiguous and overlapping. Historically, the terms YUV and Y'UV were used for a specific analog encoding of color information in television systems, while YCbCr was used for digital encoding of color information suited for video and still-image compression and transmission such as MPEG and JPEG. Today, the term YUV is commonly used in the computer industry to describe file-formats that are encoded using YCbCr.

Yokosuka R2Y

The Yokosuka R2Y Keiun (景雲 - "Cirrus Cloud") was a prototype reconnaissance aircraft built in Japan late in World War II.

Design and development

Commissioned for the Imperial Japanese Navy after the R1Y design was cancelled due to its disappointing performance estimates, the R2Y used coupled engines driving a single propeller and also featured a tricycle undercarriage.

Completed in April 1945, the prototype made a short flight on 8 May, but was destroyed in a US air raid only a few days later, thus ending development.

A proposal was also made to develop the R2Y into a turbojet-powered light bomber by replacing its piston engines with two Mitsubishi Ne-330s. Designated the R2Y2 Keiun-Kai, the prototype was begun but never completed.
