The VIA VT1622A is a digital TV encoder with enhanced text quality to provide a high quality, flicker-free viewing experience for both NTSC and PAL television formats. The VT1622A also features VIA's ProScale™ multi-resolution scaler, a de-flicker filter, and digital video encoder. The VIA VT1622A receives signal data input in either RGB or YCrCb format and generates video data as composite, S-video, component interlaced and progressive scan output, enabling the use of digital television sets.
"The VIA VT1622A TV encoder will greatly enhance VIA's platform capabilities for total connectivity solutions for the home, office and school, such as through our EPIA series of small form factor mainboards," commented Steve Chen, Product Manager for VIA Multimedia and Executive Assistant to the CEO, VIA Technologies, Inc. "With its enhanced text resolution capabilities, this new TV Encoder will make it much easier for users to navigate their PC environments using non-PC display devices, and help maintain VIA's strong position in strategic markets such as set-top boxes where this feature is crucial."
Something like this is already in the product range of VIA, the VT1622/VT1622M Digital TV Encoder. Improvements like this are not widely used I think at least not in laptops, When I connect my laptop to my television the image quality in Windows is really terrible.
