+ <entry>V4L2_DV_FL_REDUCED_BLANKING</entry>
+ <entry>CVT/GTF specific: the timings use reduced blanking (CVT) or the 'Secondary
+GTF' curve (GTF). In both cases the horizontal and/or vertical blanking
+intervals are reduced, allowing a higher resolution over the same
+bandwidth. This is a read-only flag, applications must not set this.
+ </entry>
+ </row>
+ <row>
+ <entry>V4L2_DV_FL_CAN_REDUCE_FPS</entry>
+ <entry>CEA-861 specific: set for CEA-861 formats with a framerate that is a multiple
+of six. These formats can be optionally played at 1 / 1.001 speed to
+be compatible with 60 Hz based standards such as NTSC and PAL-M that use a framerate of
+29.97 frames per second. If the transmitter can't generate such frequencies, then the
+flag will also be cleared. This is a read-only flag, applications must not set this.
+ </entry>
+ </row>
+ <row>
+ <entry>V4L2_DV_FL_REDUCED_FPS</entry>
+ <entry>CEA-861 specific: only valid for video transmitters, the flag is cleared
+by receivers. It is also only valid for formats with the V4L2_DV_FL_CAN_REDUCE_FPS flag
+set, for other formats the flag will be cleared by the driver.
+
+If the application sets this flag, then the pixelclock used to set up the transmitter is
+divided by 1.001 to make it compatible with NTSC framerates. If the transmitter
+can't generate such frequencies, then the flag will also be cleared.
+ </entry>
+ </row>
+ <row>
+ <entry>V4L2_DV_FL_HALF_LINE</entry>
+ <entry>Specific to interlaced formats: if set, then field 1 (aka the odd field)
+is really one half-line longer and field 2 (aka the even field) is really one half-line
+shorter, so each field has exactly the same number of half-lines. Whether half-lines can be
+detected or used depends on the hardware.
