1080p is a video display format, the foreign language letter P means progressive scanning (P rogressive scanning );
It is the highest level of the American Society of Motion Picture and Television Engineers (SMPTE) formulated the format of high-definition digital television standards, the effective display format for: 1920 × 1080. It is the digital high-definition signal digital television scan line of different into 1080P, 1080I, 720P (i is interlace, interlaced meaning, p is progressive, progressive meaning). Is a progressive scanning under the resolution of 1920 × 1080 display format. It is the perfect blend of digital TV and computer technology.
Basic introduction Chinese name: 1080P P meaning: progressive scanning screen resolution: 1920 × 1080 1080p only specification: vertical pixels (equivalent to the horizontal scan line) Introduction, set, projector, cell phone, monitor, technical differences, TV, HDTV, supporting programs, related to the description of the 1080p 1080p is a display format that achieves a resolution of 1920 × 1080 under progressive scanning, which is a perfect blend of digital TV and computer technology. Strong> 1080p is a video display format, the foreign letter P means progressive scan ( P rogressive scan), different from 1080i interlaced scan (interlaced scan). The number 1080 means that there are 1080 horizontal scan lines in the vertical direction. Usually, the resolution of 1080p is 1920×1080. The frame rate is usually 25, which can be expressed after p, such as 1080p25, meaning that there are 25 frames in a second. Other common frame rates are 24, 30, 60, and so on. HDMI is not necessarily 1080p output, the screen does not have to be able to support 1920 × 1080 to be considered 1080p output, as long as the horizontal scan lines more than 1080 can be called 1080p, horizontal pixel points are not strictly regulated, Full HD is the standardization of vertical and horizontal scanning pixels, 1080p only regulate vertical pixel points (equivalent to horizontal). 1080p only regulates vertical pixel points (equivalent to horizontal scan lines). Set Projector 1080P projector is the top of the home market, of course, the high price is also its best representative, although the price of Full HD projector has been greatly reduced, but as the top of the product it is still in a fairly high position. 1080P HD projector on the market can be roughly divided into three grades: high, medium, low three grades, low-end products mainly for the entry-level market, the price is mostly in the vicinity of 20,000 yuan, from the performance point of view, can fully meet the need to watch a variety of high-definition video, in the projector adjustment tends to be more simplified, mainly for entry-level users can quickly set up a projector, but this kind of contrast projector Generally not particularly high, the overall picture effect is also relatively general; mid-range projector is mainly a certain knowledge of the projector, the funds are also more abundant users, the price of such products is generally around 30,000 yuan, the projected image also has a more excellent performance, the most important contrast of the cinema projector is also a great improvement in the adjustment of the projector tends to be more professional, but also equipped with a variety of enhancement of the projection effect of the Additional features; high-end products are mainly for enthusiast players, both price and performance are the symbol of the flagship. From the technical point of view, the image projector is mainly used in DLP, 3LCD and LCoS three kinds of projection technology, due to the three kinds of technology have their own advantages and disadvantages, the application of the field is not the same. DLP in the 1080P projector appears less, mainly due to a single piece of DLP, although in the contrast is more outstanding, but its overall performance in terms of color is not particularly outstanding, and 3DLP The price of 3DLP is too high; 3LCD is 1080P cinema projector using the most technology, in the high, medium and low-end products can see his presence, which is mainly due to its excellent color performance; LCoS is currently undergoing rapid development of a projection technology, which fully combines the advantages of 3LCD and DLP, but its biggest drawback is that due to technological constraints, yields are still low, but also directly lead to its price is also relatively high, so the price is also relatively high. The biggest disadvantage is that due to technical limitations, the yield rate is still relatively low, but also directly lead to its price is also relatively high, so LCoS is mostly found in high-end projectors. Cell phones The resolution of the cell phone display has entered the era of 1080p, and the new flagship cell phone models of major brands in the iOS, Android, and WP camps all support a resolution of 1920*1080.Sony Xperia Z1 Sony Xperia Z2 HIKe X1 1080P fully laminated screen Sony Xperia Z3 Sony Xperia Z3+ (Z4) Coolpad DASHIN NOTE 3

In the many LCD products, ASUS, Samsung, LG and other top international manufacturers began to promote 1080P high-definition movies, games, high-quality entertainment to consumers. Therefore, in 2010, the computer LCD monitor, HDMI interface began to become standard. 1080P HD Movie 1080P in Security ACUTElogic Full HD Camera Module 1080P/30FPS ACUTElogic Full HD Camera Module Auto Sync Video is a video surveillance system that allows users to easily and intuitively access the full range of video content on their PC.

In layman's terms, we can divide the picture on the TV into many, many scanning lines in the horizontal direction, the finer the division, the clearer the picture, and the number of scanning lines in the horizontal number of lines will be more. The unit of sharpness is "TVLine", also known as line. This means that each line of scanning lines is erected horizontally and multiplied by the aspect ratio of 4:3 or 16:9 to form the number of horizontal rows. The following are a few common TV scanning formats: D1 for 480i format, same definition as NTSC analog TV, 525 vertical scan lines, 480 visible vertical scan lines, 4:3 or 16:9, interlaced/60Hz, line frequency of 15.25KHz. D2 for 480P format, same specification as progressive scan DVD, 525 vertical scan lines, 480 visible Vertical scanning lines 4:3 or 16:9, resolution 640 x 480, progressive/60Hz, line frequency 31.5KHz. D3 is 1080i format, which is the standard digital TV display mode, 1125 vertical scanning lines, 1080 visible vertical scanning lines 16:9, resolution 1920 x 1080, interlaced/60Hz, line frequency 33.75KHz. D4 is 720p format, which is the standard digital TV display mode, 750 vertical scanning lines, 720 visible vertical scanning lines 16:9, resolution is 1280 x 720, progressive/60Hz, line frequency is 45KHz. D5 is 1080p format, which is the standard digital TV display mode, 1125 vertical scanning lines, 1080 visible vertical scanning lines 16:9, resolution is 1920 x 1080, interlace/60Hz, line frequency is 33.75KHz. The resolution is 1920 x 1080 progressive scan, a professional format. In addition, there is also 576i, which is the standard PAL TV display mode, 625 vertical scan lines, 576 visible vertical scan lines 4:3 or 16:9, interlaced/50Hz, notated as 576i or 625i. In the above standards, "i" denotes interlaced, and "P" denotes progressive. "HDTV standard is a high-quality video signal standard, including 1080i, 720p, 1080p, that is, D3, D4, D5 belongs to the HDTV standard, support for 480p is also known as the support of HDTV. It should be noted that, for the processing power of the TV (such as frequency bandwidth) is required to be 480i & lt; 480p & lt; 480p & lt; 480i & lt. 480p<1080i<720p. So there are very few televisions that support colorimetric input 720p, but there are many that support 1080i or 1080i Ready. High Definition Television Digital High Definition Television 720P, 1080i and 1080P are the high-definition standard formats determined by the Society of Motion Picture and Television Engineers, of which 1080p is known as the top display format for digital TVs, and this format is capable of achieving a resolution of 1920 x 1080 under progressive scanning. Earlier in the world, only displays of 60 inches or more were able to display a 1920 x 1080 signal. The so-called 1080P high-definition digital TV appeared on the market and can not really bring consumers 1920 × 1080 image, these color TV is only able to receive and process the 1920 × 1080 format signal only, due to the cable signal can not reach such a high standard, 1080P for ordinary users basically has no practical value, just a manufacturer of a market publicity gimmick. With more and more HDTV programs downloaded from the Internet, the launch of Kmplayer software, PowerDVD, WinDV high-definition playback features increase, HDTV players began to be accepted by the market, HDTV and we are getting closer and closer. Many people are beginning to understand HDTV. When it comes to HDTV, many people think that it is very simple, not just 720p, 1080i, but at most 1080p. However, many people do not know that there is no difference between 1080i and 1080p for flat-panel TVs. Not many people know that 720p is only a standard used by a few TV stations in the United States. Many of the concepts of HD are false, and even 720p, 1080i and 1080p are not recognized correctly. Let's go back to the source, from 720p, 1080i and 1080p concept to start, to correct some of the misconceptions in terms of high-definition, to understand the true nature of high-definition. Recognize high-definition from interlaced progressive scanning to start: 720p, 1080i in the i is interlace, on behalf of interlaced scanning; p is Progressive, on behalf of progressive scanning. To make clear these two terms, but also from the analog CRT TV, the traditional CRT TV, the principle of work is through the electron beam on the screen line by line scanning after the light to display the image. Television signals in the transmission process, due to the limitations of the bandwidth, can only pass the interlaced signal to save bandwidth. NTSC TV, for example, at work, a 525-line image into two fields to scan, the first field called odd field, only scanning odd lines (scanning 1, 3, 5... lines), and the second field (even field) only scanning even lines (scanning 2, 4, 6... lines), through the two scanning to complete the original image frame! The number of lines scanned, because the human eye has a visual retention effect, so look in the eye is still a complete picture, which is interlaced scanning. NTSC program *** 525 lines of scanning lines, 60 images per second, expressed as 60i or 525i, if it is a progressive scanning, it is referred to as 60P or 525p. PAL program 625 lines, 50 images per second, expressed as 50i or 625i, progressive, it is referred to as 50i or 625i, progressive, it is referred to as 60i or 525i. 625i, or 50p or 625p if progressive.Remember, this is for CRT televisions. The above representations represent not only the scanning format of a CRT TV, but also the format of the images captured by the camera. Because the television system is initially interlaced system, corresponding to the NTSC and PAL television program camera, also all interlaced, that is to say, where the television camera to capture the NTSC/PAL program, all interlaced signals, respectively, expressed as 525/60i and 625/50i. remember, this is for the television camera. For analog TV images, expressed in scanned lines, PAL is 625/50i; NTSC is 525/60i. For digital signals, they are expressed in pixels or resolution, for example, PAL programs with a resolution of 720*576 can be expressed line by line as 576p, interlaced as 576i. NTSC has a resolution of 720*480, line by line as 480p, interlaced as 480i. Remember, this is for TV images.

From the perspective of consumer interest, the more intuitive parameters are clarity, SMPTE (Society of Motion Picture and Television Engineers) will be digital high-definition signals digital television scan line of the different into 1080p, 1080I, 720p (i is the interlace, interlaced meaning, p is progressive, progressive meaning). To make it clear 1080p, we first need to 1080i and 720p to make it clear. 1080i and 720p is the same internationally recognized digital high-definition television standards. The original NTSC countries use the 1080i/60Hz format, the same as the NTSC analog TV field frequency. While Europe and China and some other countries such as the original PAL system used 1080i/50Hz mode, the same field frequency and PAL analog TV. As for 720p, it has become an optional standard due to the deeper penetration of IT manufacturers into the TV industry, and it has started to expand its territory in the field of HDTV players using optical disks as carriers. The Japanese digital TV standard, for example, is divided into the following five specifications according to the different display formats: D1 for 480i format, the same definition as NTSC analog TV, 525 horizontal scanning lines, 480 visible horizontal scanning lines, 4:3 or 16:9, interlaced/60Hz, line frequency of 15.75KHz. D2 for 480P format, the same specifications as progressive scanning DVDs, 525 horizontal scanning lines, 420p format, 525 horizontal scanning lines, 525 horizontal scanning lines, 525 horizontal scanning lines. The same as progressive scan DVD specification, 525 horizontal scanning lines, 480 visible horizontal scanning lines 4:3 or 16:9, resolution of 640 x 480, progressive/60Hz, line frequency of 31.5KHz. D3 is 1080i format, which is the standard digital TV display mode, 1125 horizontal scanning lines, 1080 visible horizontal scanning lines 16:9, resolution of 1920 x 1080, interlaced/60Hz, line frequency of 15.75KHz. D4 is 720p format, which is the standard digital TV display mode, 750 horizontal scan lines, 720 visible horizontal scan lines 16:9, resolution of 1280 x 720, progressive/60Hz, line frequency of 45KHz. D5 is 1080p format, which is the standard digital TV display mode, 1125 horizontal scan lines, 1080 visible horizontal scan lines 16:9, resolution of 1920 x 1080, progressive/60Hz, line frequency of 45KHz. scanning lines, 1080 visible horizontal scanning lines 16:9, resolution of 1920 x 1080 progressive scanning, professional format, line frequency of 67.5KHz. In addition, there is also the 576i, which is a standard PAL TV display mode, 625 vertical scanning lines, 576 visible vertical scanning lines, 4:3 or 16:9, interlaced/50Hz, notated as 576i or 625i. The D3's 1080i is used as the basic format for HDTVs, but it is also compatible with 720p format playback. While the D5 specification of 1080p as an advanced professional mode, commonly set for television stations, movie production. The 1080i and 720p TV signals transmitted by TV stations are converted for broadcast by 1080p sources. As you can see, 1080p is a de facto standard, but 1080p is not the standard used in the civilian field. 1080p is not only a 60Hz field frequency, in fact, the real set of the most used is 24Hz, 25Hz, 30Hz three field frequency specifications. We know that movies play film at 24 frames per second. Digital images shot in 1080p/24Hz can be transferred without loss to digital movie projectors such as DLP/D-ILA and played in movie format.1080p/24Hz is a format prepared for movies. If high-definition content is captured in the 1080p/25Hz format, each full 1080p frame can be easily split into two interlaced 1080i frames. This turns the 1080p/25Hz format into a 1080i/50Hz image, making it easy to apply to high-definition digital TV signals in the former PAL countries of Europe and China. Similarly, 1080p/30Hz can be easily converted to 1080i/60Hz after shooting, which can be easily applied to the original NTSC HDTV signals in countries such as ATS in the U.S. and ISDB in Japan. Summary Above said so, some like a tongue-twister like, but also some long-winded, but for the concept of high-definition 720p, 1080i and 1080p is a must, said so, we should remember, for the high-definition, for the concept of 720p, 1080i and 1080p, it must be from the television, video cameras and image format of the three aspects of knowledge, television, video cameras and image formats itself is different but related to different concepts. Definition of high-definition are different: High Definition Television, also known as HDTV, in accordance with the definition of the CCIR International Radio Advisory Committee, HDTV image ratio is 16:9, the viewer in the screen height of three times the distance viewed, the image should be transparent, and the real object is basically close. According to the definition of the ITU International Telecommunication Union, HDTV has about twice the clarity in the horizontal and vertical directions of conventional television sets, the image aspect ratio of 16:9. subjective image quality and interlaced HDTV studio standards. Image format:In addition to a few individual U.S. television stations specified 1280 * 720 for HDTV standards, countries around the world, including China, Europe, Australia, Japan, South Korea, a new generation of high-definition discs HD DVD and BD, the resolution standard is 1920 * 1080, the United States outside of the United States, there is no country to adopt the 1280 * 720 standard. This still does not see how the concept of 720P, 1080i and 1080P came about. Please readers do not be anxious, slowly down to see. We mention high-definition, immediately associated with LCD, plasma and other flat-panel TVs, and the development of high-definition standards, the earliest and traced back to the 1980s, the United States of America's high-definition standards determined in the 1990s, has been more than 20 years, when flat-panel TVs have not yet appeared, the development of standards is considered from the CRT TVs, and therefore said the concept of 720P, 1080i and 1080P, with a strong CRT flavor. The concept of 720P, 1080i and 1080P has a strong flavor of CRT. But CRT has been eliminated, flat-panel TV has taken its place. For liquid crystal and plasma TV, belonging to the fixed pixel display device, display images do not need to scan, and each pixel can be considered to be the same time light, if you have to be linked to the concept of interlaced line by line, you can think of liquid crystal and most plasma TVs are progressive scanning. So does that mean 720p, 1080i and 1080p can be canceled, the answer is no, because there is a camera format. From the camera point of view, high-definition cameras, although digital, but the scanning method is used from the analog camera along, the traditional analog camera, all interlaced, and high-definition cameras, in order to retain the interlaced scanning format at the same time, but also increased the progressive scanning format. High-definition cameras not only retained the interlaced, progressive points, but also retained the PAL system 50Hz frequency and NTSC 60Hz frequency difference, although high-definition has no PAL and NTSC respectively, but in the United States, Japan, South Korea, these traditional NTSC region, still retains the 60Hz frequency system, and China, Australia, Europe still retains the 50Hz system. HDTV programs are all digital signals, so it is sufficient to express them in terms of resolution. HDTV is divided into interlaced and progressive scanning when shooting, and the frame rate (the number of progressive images displayed per second) or field rate (interlaced images displayed per second) is also different. 1280 * 720 there are five kinds of frame rate, respectively, 60P, 50P, 30P, 25P, 24P, can be referred to as 720P, and can be expressed as 720/60P (the United States ABC TV station used); 720/50P; 720/30P, 720/24P (FOX station); 720/25P. which 720/50P, 720/25P. Originally there was no, then Germany in the choice of high-definition image standard, had intended to choose 720P system, taking into account the German tradition is a 50Hz system country, so some manufacturers launched to support the 720/50P, 720/25P camcorder, but there is no country to choose this standard, at best, is an issue only. The situation of 1920*1080 is more complicated, the interlaced one is expressed as 1080i, and the progressive one is expressed as 1080P. In the United States and Japan, where the field frequency is 60Hz, it can be expressed as 1080/60i, and in our country, Europe, and Australia, it is 1080/50i, and both of these two formats can be referred to as 1080i. Things don't end here, and in order to facilitate the production and exchange of high-definition programs , the standard of 1080/24P has been uniformly adopted worldwide, and this standard is also used as the standard of digital movie camera, the famous Star Wars prequel is shot with 1080/24P camera, and many high quality TV dramas, such as The Big House, are also 1080/24P, or 1080P for short. However, this is still not the whole connotation of 1080P for flat panel TVs. In fact, it can be argued that there is no difference between 1080i and 1080P, because the image processing circuit technology is developing very quickly, the computing speed is very fast, the processing power is very strong, all with line doubling technology. The so-called line doubling technology is the interlaced 1080i image processing into line-by-line 1080P image, 1080/50i can be perfectly processed into 1080/50P, 1080/60i processed into 1080/60P, including 1080/24P program, can be very easy to deal with 1080/50P or 1080/60P. and any one of the Flat panel TVs have this circuitry, and slightly higher-end flat panel TVs handle it well. More HD flat panel controversy: speaking of this, it seems that the format of the TV set has not been spoken of yet. Regarding the format of the TV set, it is more complicated, LCD and plasma TVs have different resolution levels, and countries and regions have different opinions on how much resolution LCDs and plasmas can be considered high-definition. The United States Consumer Electronics Association ECA and the European Communications Appliance Industry Association EICTA stipulates that the resolution of high-definition television sets must reach 1280 * 720 or more. In accordance with the Ministry of Information Industry announced high-definition national standard, high-definition flat-panel TV resolution must reach 1280 * 720. that is, if the resolution of liquid crystal and plasma less than 1280 * 720, can no longer be called high-definition television. LCD TV resolution all can reach the standard, but the plasma can be hilarious. 42-inch plasma, the resolution of the following four, respectively: 852 * 480, 1024 * 768, 1024 * 1024 and 1024 * 1080, all do not meet the requirements of high-definition national standards. Only the 50-inch plasma meets the HD national standard. More complicated, 1024 * 1024 and 1024 * 1080 two plasma, not progressive display, but alternate rows of light, said above, "you can think of LCD and most plasma TVs are progressive scanning," is because of this reason. But this issue can not be concerned, even if the interlaced display, there is no effect on the viewing effect. In flat-panel TVs, especially some of the plasma TVs that do not meet the requirements of the national standard for high-definition is still in the promotional materials said to be 1080P, the 1080P, and we said above 1080P there are different interpretations. Panasonic 42PA60C, for example, the physical resolution is only 852 * 480, does not meet the requirements of the national standard for high-definition, Panasonic said 1080P, that is, the 42PA60C can receive 1920 * 1080i signals, and can be processed into 1920 * 1080P format. However, the resolution of 42PA60C is only 852*480, which can't fully display 1920*1080 pixels, so it also reduces the resolution of HD image to 852*480 resolution to display on 42PA60C. This kind of 1080P will not be considered as HD, and accurately said that it is compatible with 1080P. Conclusion:For HD programs, in fact, the concept of 720P, 1080i and 1080P has no practical significance, with 720 representing 1280*720, 1080 representing 1920*1080 can be, because even 1080i images, flat-panel TVs can be processed as 1080P. For flat-panel TVs, 720P, 1080i and 1080P is even more meaningless, flat-panel TVs can all be considered progressive, high and low definition by the resolution of the decision, in accordance with the requirements of the national standard for high-definition at least 1280 * 720, of course, is the 1920 * 1080 physical resolution of the best, but this is and 720P, 1080i and 1080P has nothing to do. The only still need 720P, 1080i and 1080P concept, is the concept of high-definition cameras, but for TV viewers, we just need to watch the program is good, as for what format camera shooting program, does not affect the viewing effect.
