The OpenGL radar-scan converter does its scan conversion computations on the graphics processor ( GPU ) to achieve high performance and visual quality.
2.
In order to broadcast the SSTV transmission on standard television, NASA ground receiving stations performed real-time scan conversion to the NTSC television format.
3.
The OpenGL RSC is implemented using a reverse scan conversion approach which calculates for every image pixel the most appropriate radar amplitude value in the polar store.
4.
The STIC fetches the results in the FIFO and passes them on to the STAMP ASIC ( s ), which performs scan conversion and other graphical functions.
5.
Once the color was decoded, scan conversion was not necessary because the color camera ran at the same 60-fields-per-second video interlace rate as the NTSC standard.
6.
The application of scan conversion is wide and covers video projectors, cinema equipment, TV and video capture cards, standard and HDTV televisions, LCD monitors, radar displays and many different aspects of picture processing.
7.
"' Scan conversion "'or "'scan converting rate "'is a video processing technique for changing the vertical / horizontal scan frequency of video signal for different purposes and applications.
8.
The SC ASIC and the TA ASIC perform scan conversion, color and depth interpolation, perspective correct texture coordinate interpolation and level of detail computation on incoming data, and the results are passed to the eight TM ASICs, which are specialized memory controllers optimized for texel access.
