Digital TV for Dummies
And secondly, Sharp has introduced a new HD 3D TV with an added gimmick. They call it “QUATTRON”. As explained earlier, all video media broadcasts 3 colors. Red, Green, and Blue. Sharp’s Quattron adds a Yellow bar to their R, G, B, pixels. They claim it creates thousands of new colors. This new selling point is Bull Shit! The yellow bar they add to every pixels can only create yellow from the R, G, & B. Because the video media that transmits a yellow color separately, does not exist.
If Quattron can create yellow from the original R, G, & B, then any TV with just the R, G, & B can create the same yellow. I can also guess that a TV screen with 1 or 2 million pixels with an added color bar, that is unique to just that manufacturer, should be very expensive to fix or replace. Don’t buy this TV just because they are scamming you into it.
I hope this helped you to have a better understanding of our new digital TV system. If you have any questions on this subject, please email me at firstname.lastname@example.org, and I will try to answer in simple terms even a dummy can understand.
By the way. Just to compare resolutions and how far we have come. Standard VHS tapes had a resolution of about 340 lines at the high speed, and 260 lines at the slow speed. SDTV is 480 lines, and HDTV is 720 to 1080 lines.
