'Y' is the luma or luminance component and UV are the two "difference" chrominance components that define a YUV color. You can think of the luminance component as the intensit…y of the color. The letters themselves do not each represent a particular word - think of them more like variables in a math equation. It looks like this: U = B - Y (blue - luminance) V = R - Y (red - luminance) Georges Valensi came up with this scheme and patented it in 1938, and the broadcast industry adopted it. It prevented B&W TVs from becoming immediately obsolete when television switched to transmitting a color signal because a B&W TV could take the color signal and display the colors as shades of gray.

Interlaced YUV will only display lines 1 3 5 etc. then go to lines 2 4 6... in the next screen refresh cycle of 50 or 60 times per second depending where you live in the world…. Progressive will display all the lines at once in every cycle, so effectively twice as much info onscreen in any one cycle. For your purposes YPbPr is the same as YUV. Technically YUV is a type of colour gamut, or colour space standard to ensure colours match from one device to the next. YPbPr is an analog connection using this colour space standard and uses three cables (red, blue & green) just for the picture. YCbCr is a digital version of this. Both are commonly called Component. For the average home TV viewer these terms are all interchangeable - YUV, YPbPr and YCbCr. Even the sales assistant is unlikely to have a clue there is a difference. It is chips with faster clock cycles and processing power that have helped us attain this point. The newer players and TVs allow even more lines on-screen than the original Standard Definition (SD) TV lines of 576 (PAL) or 480 (NTSC). A DVD is however only SDTV resolution. To get more definition onscreen you need to be receiving an HDTV (1280x720) signal normally arriving via satellite dish (DVB-S), a FullHDTV (1920x1080) signal from a ground transmitter (DVB-T), or a Blu-ray Disc player (1080). Cable TV (DVB-C) can be in almost any resolution as it is encoded to suit the bandwidth available and often the resolution is traded off for the number of channels the station want to make available.
