SPRM 14: Player Video Configuration
Every DVD player has several modes of video display. These are divided into the display
mode and the aspect ratio. By reading SPRM 14 you can tell what modes the player is
currently in. Bits 8 and 9 of SPRM 14 are used to determine the current display mode
(whether the video needs processing for display on a 4:3 monitor) and bits 10 and 11 are
used to determine the aspect ratio of the monitor (4:3 or 16:9). The first eight bits in SPRM
14 are not used.
The following table shows the combinations for the display mode bits.
