YPbPr is the component video format in which the luminance (Y) is represented separately from the color components (Pb and Pr). The majority of HDTVs today support this format. These HDTVs accept the YPbPr formatted video per EIA specification 770.3. The Y output on HDTVs and HDTV receivers is provided as a green jack, the Pb is provided as a blue jack, and the Pr is provided as a red jack. The colors themselves are not to be confused as an RGB output. The Explorer 3100HD has a YPbPr output only.
