2 | On Screen Display cx23415 Framebuffer driver | |
3 | ||
4 | This module presents the cx23415 OSD (onscreen display) framebuffer memory | |
5 | as a standard Linux /dev/fb style framebuffer device. The framebuffer has | |
be383bd3 | 6 | support for 8, 16 & 32 bpp packed pixel formats with alpha channel. In 16bpp |
32db7754 HV |
7 | mode, there is a choice of a three color depths (12, 15 or 16 bits), but no |
8 | local alpha. The colorspace is selectable between rgb & yuv. | |
9 | Depending on the TV standard configured in the ivtv module at load time, | |
10 | the initial resolution is either 640x400 (NTSC) or 640x480 (PAL) at 8bpp. | |
11 | Video timings are locked to ensure a vertical refresh rate of 50Hz (PAL) | |
12 | or 59.94 (NTSC) | |
