+ On Screen Display cx23415 Framebuffer driver
+
+ This module presents the cx23415 OSD (onscreen display) framebuffer memory
+ as a standard Linux /dev/fb style framebuffer device. The framebuffer has
+ support for 8, 16 & 32 bpp packed pixel formats with alpha channel. In 16bpp
+ mode, there is a choice of a three color depths (12, 15 or 16 bits), but no
+ local alpha. The colorspace is selectable between rgb & yuv.
+ Depending on the TV standard configured in the ivtv module at load time,
+ the initial resolution is either 640x400 (NTSC) or 640x480 (PAL) at 8bpp.
+ Video timings are locked to ensure a vertical refresh rate of 50Hz (PAL)
+ or 59.94 (NTSC)
