## 4. Features

- anything vdr can do and will do
- handles the overlay of your dvb-cards
- lets you zap through your video devices or display up to for overlays at once (if you have more than one card). However - changing the channel via vdr is currently only supported on the "primary" dvb-interface.
- The picture in picture allows you to follow the movie at the other device in the small image. You can exchange those by a single key-press.
- the Xv-mode lets you zoom the image to larger resolutions and optionally handles deinterlacing by 50Hz half frame upscaling or field1 upscaling.
- fullscreen-mode (mouse, dpms and screensaver automatically handled)
- can be used for "remote" viewing of vdr-recordings if you have 2 dvb-cards and the remote-video-directory mounted
- let's you grab images during viewing, playback or recording in jpg or pnm format, filename is automatically generated out of channel-name, date and time.
- let's you control Brightness, Colour, Hue and Contrast of the overlay (not applied to grab-images!)
- handles 4:3 and 16:9 aspect ratios corrected with viewport-dimensions (currently at 4:3 monitors only)
- handles PAL and NTSC accordingly (but only PAL tested so far - i'am living in Germany ;-)
- stores all configuration to file
- sound-handling: mixer-channel, volume and mute using alsa/amixer
