Basic comparison: analogtv, SDTV, EDTV and HDTV
There was a time when we had only one choice when buying a TV from analog TV or conventional CRT TV. But today we have so many possibilities. First, we have our traditional CRT (Cathode Ray Tube) TV. Along with this we have new possibilities such as HDTV, EDTV and SDTV. But what is right for you? What are the main differences in them? We try to understand the basics about each of them.
Conventional analog TV:
First, we talk about our traditional CRT TV. VideoCRT TV screens contain 525 lines of resolution, although only 480 lines are displayed. These lines get painted with interlacing technology. In this technique, first painted all the odd lines from 1 to 479th Immediately after that is numbered all the colors straight from 2 to 480th This standard analog TV standard is AS 525 interlaced or 525th, this condition as "480th". The screen ratio is 4:3. This TV has a NTSC tuner, so by default you can notTune digital TV broadcasting.
Hdtv
Analog TV:
With the NTSC broadcast for 50 years, was dominant. But it's time to DTV (digital TV) to replace the analog one. Digital TV is a new type of broadcasting technology that delivers images of TV and film-quality Dolby Digital surround sound, along with a host of other improvements. Digital TV works with ATSC instead of NTSC transmission. Currently, there are three types of digital broadcast signals: SDTV,EDTV and HDTV. Aspect ratio is 16:9 for DTV.
SDTV:
As analog TV, SDTV, and 480i. That's the advantage over analogue – SDTV, digital signals to be received.
EDTV:
So far, 480i TV worked fine. This is because television is limited to sizes 19 inches or 20 inches. But it seems that limits the resolution of 480i, when the same technology is in wide screen. interlacing techniques do not work for a larger screen. The lines of visible image and the stairs are annoying. L 'best solution is to avoid the interlacing. Before Interlacing was invented to save bandwidth transmission. But in the transfer of existing technologies to much higher prices are possible. So there is no need for interlacing. E 'can paint lines 1,2,3 …. up to 480, this is "progressive scan" like. With this technology, using the same resolution of 480 lines, we can get better video quality, can eliminate jagged edges. This 480-line progressive scan technique iscommonly known as 480p. This concept in the consumer market is known as EDTV or Enhanced Definition Television.
Both SDTV and HDTV, the 16-by-9-items supplied with the ratio 4-by-3 aspect.
HDTV:
Even if we took the SDTV and HDTV digital broadcasting system, the greatest attention HDTV. A major advantage here is the number of rows is magnified on the screen. HDTV comes with three flavors, 720p, 1080i and 1080p younger. As the name suggests, the firstResolution 720 lines progressive and interlaced displays second display 1080 lines. If we compare these two, we can say that both are good. In general, 720p more appropriate for fast action, as it uses frames progressive alternative in 1080i is very good for slow motion pictures (probably the reason most HDTV showroom can be seen slowly moving film). 1080p on the other hand, offers a resolution of 1920 x 1080 pixels. This ensures the bestSelect to compare it with others. That's because 1080p maximum number of pixels, compared to other varieties, more than 1080 lines of progressive scan lines, whereas the best of you, interlaced.
