+           <entry>If set, then this is a Consumer Electronics (CE) video format.
+Such formats differ from other formats (commonly called IT formats) in that if
+R'G'B' encoding is used then by default the R'G'B' values use limited range
+(i.e. 16-235) as opposed to full range (i.e. 0-255). All formats defined in CEA-861
+except for the 640x480p59.94 format are CE formats.
