- 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)
