With the development of the Internet, many people have purchased smart TVs at home, and there are more and more 2K and 4K TVs. However, due to price reasons, 1080P TV is still the current mainstream. Many people often ignore common sense when purchasing smart TVs.
Some smart TVs on the market are marked with 1080p, and some are marked with 1080i. Many people do not distinguish between the two. What is the difference between the two? Today, Xiao Bian popularizes high-definition knowledge for everyone and introduces the difference between 1080i and 1080p.
1, video format
Before talking about this issue, we must first distinguish between two concepts, one is the video source format, the other is the playback device supports the resolution.
For a video signal source, 1080i means there are 1080 horizontal scan lines, and i means an interlaced video display. When playing, it displays a single vertical picture first, then displays a double number of vertical pictures, which can save half the bandwidth of 1080p. When playing a 1080i video source, the video played is the same effect as a shutter, showing only half the area.
Unlike 1080i interlaced scanning, 1080p is a progressive scan, and the number 1080 indicates 1080 horizontal scan lines in the horizontal direction. Usually 1080p screen resolution is 1920×1080. In simple terms, if 1080p can display 60 full frames per second, 1080i can only display 30 full frames, even if they both have the same frame rate per second.
Regardless of the code rate, on the same device is video, in pure definition is 1080p = 1080i> 720p, but the actual display area of ​​1080i is only half, 1080i picture is not as smooth as 1080p smooth transition smooth. Therefore, 1080i is suitable for movies with less dramatic changes, such as documentaries and wildlife.
2, playback equipment
After talking about the video source format, let's talk about playback devices. Today's latest smart TVs and flat-panel TVs do not distinguish between 1080i and 1080p. The TVs on the market are mainly called 1080p, and the number of 1080i is not much. The TV set marked 1080P resolution can also play 1080P or 1080i. On the contrary, it is not necessarily.
In general, a TV marked 1080i may not have a resolution of 19201080, may be 852480 or other. It is indicated that 1080i refers to a format that supports 1920×1080i, while the 1080p video format has a higher bit rate and bandwidth, and this TV may not be able to be taken, and it may not be able to smoothly play a 1920×1080 format video.
With the development of the high-definition industry, 1080p video sources have become the mainstream format, 1080i video sources have become less and less, and 1080p televisions have also become mainstream. However, despite this, there are still many TV sets on the market with the name "1080i" trying to get through. Finally, I hope everyone can keep their eyes open when they purchase smart TVs and avoid being knocked out by manufacturers.
