Settings Dialog Box

The Video Settings Tab

This tab controls the appearance of the video presented in the DigiTV window.




Hardware Overlay Format

Here you can choose which FOURCC overlay format you want your graphics card to use. This may be useful if you find that your graphics card doesn't support the default UYVY format.


Video Engine

As for the Application Priority, you can force the Video engine section of DigiTV to a high priority. Usually you will not need to alter this setting, but under some conditions it can reduce the number of dropped frames.

The Enable HDTV CPU Saving option allows you to reduce the processor load on some systems when viewing High Definition video. It is recommended that you enable this option if you find that your machine is running close to 100% CPU when viewing HD content.

The Enable Frame Smoothing option forces DigiTV to smooth out the presentation of the video frames so that they occur within 1mS of their display time. However, this means that the CPU has to spend more time checking the high-resolution counter on your motherboard so you may see the CPU usage rise.

This rise is only 'perceived' because if your machine is loaded to close to 100% the worst that could happen if you select this option would be that your frame timings become less accurate. Selecting this option will not cause additional frames to be dropped if operating at near the maximum CPU loading.


Deinterlace method

TV output (even most digital TV programming) is intended for interlaced displays and that doesn't suit computer monitors very well with their progressive scans. To get over this limitation a choice of three deinterlacing algorithms have been implemented:

No Deinterlacing - The simplest method to implement of all!

Line Average - the odd and even fields are averaged over the full picture period. Full resolution is kept, but image pans and fast movement can appear blurry and take on a 'film-like' quality.
