REMOTE Specifications (continued)

■Priority of assigned functions

•When both “MARKER1” and “MARKER2” are activated at the same time, “MARKER1” has priority. However, when the display aspect ratio is 4:3, the “MARKER1” aspect ratio is 16:9 and the “MARKER2” aspect ratio is 4:3, “MARKER2” is displayed. In this case, the “MARKER2” background is controlled.

•When “MARKER BACK HALF” and “MARKER BACK BLACK” are activated at the same time, “MARKER BACK BLACK” has priority.

•During GPI edge operation and two or more of “INPUT SEL. VIDEO”, “INPUT SEL. SDI1”, “INPUT SEL. SDI2”, “INPUT SEL. YPBPR/RGB” and “INPUT SEL. DVI-D” are simultaneously activated, priority goes to the last activated item. During level operation, priority is assigned in the following order: “INPUT SEL. VIDEO”, “INPUT SEL. SDI1”, “INPUT SEL. SDI2”, “INPUT SEL. YPBPR/RGB” and “INPUT SEL. DVI-D”.

•When “GAMMA SEL. FILM” and “GAMMA SEL. STDIO/PST” are activated at the same time, “GAMMA SEL. FILM” has priority.
