What's the difference between 1080p and 1080i, and which is better?
Technological progress, or, better to say, the race for technological excellence, does not stop and is unlikely to ever stop. The consequence is the tremendous speed of change taking place in the electronics industry. The technical capabilities of devices of the past, such as, for example, a television on a CRT (cathode ray tube), cannot be compared with the picture quality provided by new devices created thanks to inventions and discoveries in the field of electronics and microelectronics. Flat panel LCD and plasma TVs can be hung on the wall - fifty years ago it was difficult to imagine. Buying an HDTV leaves the buyer with a choice of the appropriate resolution - 1080p or 1080i... This article will help you figure out which choice should be made in each specific case.
The differences between 1080p and 1080i are primarily technological... When choosing a TV, attention is paid to its cost and quality. The latter depends primarily on the type of permission. To understand which choice is correct, you should consider the differences in the construction of images in the considered video modes.
So. What does the number 1080 matter? What we really mean here is a screen resolution of 1920 x 1080 pixels. The first number is their number horizontally, the second, respectively, vertically. A pixel is the smallest element of the screen, a point, the more there are, the higher the quality of the displayed image is. Both 1080i and 1080p screen resolutions are the same, only the scanning technologies used in each case are different. The details of these differences are discussed later in this article.
The “i” in TV quality refers to interlaced, “p” to progressive or non-interlaced. Scanning is a method of constructing an image on a screen. A cathode ray tube and an electron beam have been used in CRT televisions. Interlaced scanning, in which either even or odd lines are involved in the construction of an image (that is, "through a line"), is now considered an outdated scanning method compared to progressive scanning. The latter implies scanning all lines one by one, without gaps. The difference in picture quality in this case is significant, which is clearly noticeable, first of all, in CRT TVs.
Flickering is the main drawback of 1080i TVs that differentiates them from their 1080p counterparts. Screen blur is a consequence of this disadvantage, which is not seen with progressive scan devices. But it should be noted that modern televisions, having different scanning methods, do not have such significant differences in image quality as in CRT monitors.
The advantage of progressive scanning is well felt during video games - progressive scanning is preferable for displaying fast-changing images. The graphics of modern games are displayed in the best quality on monitors with progressive scanning (1080p).
For the consumer looking to purchase an HD monitor for gaming and video applications, 1080p is the best choice. 1080i quality will be enough for those users who are more interested in movies and TV shows.
1080P in DVR modes can be listed as AHD-H and 1080N as AHD-NH. So what's the difference? It seems that both means a 2MP resolution (as some unscrupulous sellers claim). Actually this is not true. 1080P is a resolution of 1920 pixels horizontally by 1080 pixels vertically. 1080N - 960 horizontal by 1080 vertical. That is, 1080N has half the horizontal resolution of 1080P. Here is a picture to make it clearer and clearer:
But when displaying a picture, 1080N has the same aspect ratio as 1080P - 16: 9. This is due to the coding principle of the 1080N signal. 1080N recording is interlaced. And during playback, the picture is stretched and smoothed horizontally.
This is what the picture looks like at 1080P: 
And like this at 1080N without hardware processing:
It is noticeable that at 1080N the image is narrower.
If we compare 1080N after hardware processing and 1080P, then the differences are not very noticeable:
1080N 
1080P
The differences are already apparent in the details, if you zoom in on the image:
1080N
So the detail on 1080N is worse than 1080P, but not as catastrophic as you might think. This is with regard to the "cons".
On the plus side, I can say that 1080N DVRs are cheaper than 1080P. Among other things, 1080N recording takes up less hard disk space, which is important in some situations. Therefore, where the detail of the picture is not very important, you can safely connect AHD DVRs with 1080N mode. And vice versa, where picture quality matters, for example, above the cash register, it is worth looking at more expensive video surveillance systems.

When the question of ship insurance arises, many of our clients are often interested in the question of how an insurance company differs from a P&I club and how the terms of “club” insurance differ from insurance in a regular insurance company.
Below you will find the answer to this question.
Any insurer, receiving insurance premiums, forms an insurance fund from which he then reimburses money in case of loss.
The peculiarities of the movement of financial flows through the insurance fund predetermined the methods of its formation and operational management.
In the first case, it remains at the disposal and economic use of its participants and does not pursue the goal of making a profit. This method was named mutual marine insurance
In the second case, the insurance fund is transferred to the disposal and economic use of a specially created financial institution and sets the goal of making a profit. This method is named stock marine insurance.
In modern conditions, the issues of organizing and conducting mutual maritime insurance are in charge of the mutual insurance clubs of shipowners (Protection and Indemnity, abbreviated as P&I club), which have the character of a non-profit organization. In other words, these are shipowners who have united in a community to insure their risks. The premiums paid to the club form the club's insurance fund from which losses are then reimbursed.
Joint stock marine insurance is the responsibility of joint stock specialized or universal insurance companies. The legal norms of state regulation of the national legislation of the country of registration of these insurers are applied to the activities of mutual insurance clubs and joint-stock insurance companies.
By default, the mutual insurance club initially assigns advance calls to shipowners-insurers. Then, the club's requirements for the shipowners to pay additional insurance premiums (supplementary calls or additional calls) may follow. These claims of the club arise when the advance insurance payments are clearly not enough for the club to fulfill its obligations to pay insurance indemnity under the concluded marine insurance contracts with its members. In addition, in some cases, the club may require member shipowners to pay catastrophe calls when there is a huge property loss (such as an oil spill) requiring adequate insurance coverage.
Insurance premiums (contributions) paid to a joint stock insurance company are usually fixed and are called premium income, insurance premiums paid to the club are called call.
Mutual Insurance Clubs (KBC) refers to a number of non-profit, non-profit organizations.Their emergence was dictated by specific insurance interests that arose among shipowners in the course of merchant shipping and which, for one reason or another, could not satisfy traditional joint-stock insurance companies. For the first time, FACs appeared in England in the middle of the 19th century (1855) after the adoption of the corresponding law (British Merchant Shipping Act, 1854), regulating their activities.
Mutual insurance clubs are now incorporated associations that operate on the basis of statutes that define the nature and content of their activities. The relationship between the P&I Club and its policyholders, club members regarding marine insurance issues is governed by internal rules, as well as by the rules of international maritime law.
Service, which is provided in connection with an insured event, is of decisive importance in the practical professional activity of shipowners - members of the club. The meaning of the service provided is to help club members quickly and efficiently resolve issues in connection with the occurrence of losses, as well as provide financial guarantees. The Mutual Insurance Club Guarantee is a unique form of habit in international trade. The guarantee issued by the club, as a form of securing obligations, is accepted everywhere in the world.
The network of its correspondents is of practical value for a shipowner who has joined the club. The current trend in the activities of mutual insurance clubs is the creation of a global correspondent network in the largest ports of the world, ready at any moment to help the shipowner in resolving emerging issues. Mutual insurance clubs strive to provide their members with 24/7 access to these global networks. In turn, global correspondent networks interact with other business infrastructure (lawyers, surveyors, etc.) that clubs have. Thus, providing not only a prompt, but also a comprehensive approach to solving shipowner's issues.
A number of mutual insurance clubs are part of the International Group of P&I Clubs. The main goal of this international group is the distribution of insurance risks among its members on the basis of a pool agreement. The permanent working body of the International Group is the Secretariat located in London.
The international group of mutual insurance clubs acts as a professional association and represents the interests of its members at the regional and international levels. In particular, the International Group has observer status at IMO. About 90% of the world's transport fleet tonnage is insured in the International Group (through the corresponding insurance pool).
Yesterday Huawei unveiled the flagship smartphones Huawei P20 and P20 Pro in Paris. It would seem that these are two modifications of one smartphone, but there are still a lot of differences between them. It's not for nothing that Huawei, for the first time in the history of the P series, called the enlarged model not Plus, but Pro. By the way, I have already mentioned the first difference: the "proshka" is larger. The screen diagonal of the older model is 6.1 "versus 5.8" in the younger version. Following the dimensions of the display, the dimensions of the case have also changed: 149.1x70.8x7.65 mm for the younger model and 73.9x155x7.8 mm for the older one. Weight is 165g and 180g respectively. The difference in thickness and weight is also due to the grown battery (3400 mAh in the P20 and 4000 mAh in the P20 Pro) and water resistance (the Pro has, but the regular P20 does not).
Let's go back to the screens, however, because they differ not only in the diagonal. The panels are different in absolutely all respects! The most basic: Huawei P20 has an LCD screen, while the P20 Pro uses OLED. The OLED panel in the older model sports a conventionally infinite contrast ratio, and the LCD screen of the younger P20 boasts an impressive 770 nits brightness. It is achieved with an unusual pixel structure, RGBW (traditional three subpixels + white subpixel for more brightness). For the first time such a screen was used in the Sony Xperia P, but it is Huawei that uses them most actively. The displays also differ slightly in resolution: the Huawei P20 has 2244 x 1080 pixels (aspect ratio 18.7: 9), while the Huawei P20 Pro has 2240 x 1080 pixels (~ 18.67: 9). Why Huawei made the older model's screen four pixels shorter is not clear. Well, since the resolution is almost the same, and the diagonal is different, the P20's screen is sharper: 428 ppi versus 408 ppi. The use of OLED in the older model widens the gap in favor of the younger model.
Another significant difference between Huawei P20 and P20 Pro is the main cameras (the front ones are the same). In Huawei P20 Pro, the Chinese used the world's first triple camera, a detailed material about which we published yesterday. But Huawei P20 received a more modest dual camera, which is not much different from the one used in the company's smartphones before. It is united with the firmware camera only by a 20-megapixel black-and-white module, which is identical for the two models (at least, we could not find information about the differences between them). But the two color cameras Huawei P20 Pro (the main 40 megapixel and the telephoto 8 megapixel) are replaced in the P20 by one with a resolution of 12 megapixels and a large pixel size (1.55 microns). The aperture of this 12-megapixel camera is the same as the 40-megapixel camera of the Huawei P20 Pro - f / 1.8.
Different screens and cameras are not all that distinguishes the Huawei P20 from the P20 Pro. So, the younger model has only 4 GB of RAM, while the "firmware" received all 6 GB. Perhaps this distribution is not forever: leaks from TENAA pointed to half a dozen different modifications with different amounts of memory, so the release of the 6GB P20 (or 4GB P20 Pro) is not excluded. The set of colors is also different: Huawei P20 is available in gold color, which is not in the P20 Pro palette. Other colors are common: black, pink, blue and twilight. Finally, the prices differ: the Huawei P20 costs 649 euros (46,300 rubles), while the P20 Pro costs 899 euros (64,100 rubles).
Huawei P10 and P10 Lite. In this article we will take a look at the new product and talk about how the iphone 6 differs from the 6s? Photos taken on honor 9 and huawei p10 are not much different from each other than huawei p10 does. What do we know about the new products of the Chinese giant?
Recently, at the MWC 2017 in Barcelona, Huawei is set to unveil its latest branded phone lineup. The main novelty, of course, will be the P10 model, also its cheaper version with the addition of Lite in the title. How to distinguish I just went nuts from the quality of the display review of the huawei p10. Here's what we already understand about these giant devices.
The Huawei P10 should have a curved screen.
The most important novelty of the company in the first half of this year there will be a model P10, whose photos recently appeared on the Chinese Weibo website. What is the difference between huawei p9 lite, p8 lite 2017 and p10 lite? They said that the phone will differ little from its predecessors from the R band. Huawei p10 lite looks more expensive in Baku than its counterpart from xaomi for $ 500 differs. The body will be made of iron, and its rear panel will be very similar to that of the P9.
Huawei P10 is required to have a 5.5-inch AMOLED screen with QuadHD resolution (2560 x 1440 pixels), which will be curved on both sides. The photos show that the Chinese will put on the home button, a fingerprint scanner (previously located on the back). What is the difference between iphone 6s and iphone 7? At the end of February, the lite family was joined by another huavei - this time the p10 lite. What is the difference between iphone 6s and iphone 6? Review comparison. I must say that he is very different from his relatives, at least by their internal standards. Huawei P10 will be reminiscent of the best phones from Samsung, which, perhaps, will help it get some customers.

It can be expected that the equipment will be based on the system HiSilicon Kirin 960, which debuted in conjunction with the Mate 9. The chipset using the Mali-G71 graphics can work with 4 GB or 6 GB of RAM. The 2nd option can be reserved for a more massive version of the device with the addition of "Plus", but it's hard to find at the current time, how else it can differ from the ordinary version.

Looking at the tech specs, 4GB of RAM and up to 64GB of internal storage looks very good, which is a rarity for mid-range models. If you are confused about the names of the new huawei smartphones and want to understand how the p20 differs from the p20 lite and pro, as well as from the older p10, then we have prepared clear answers for you. However, it should be borne in mind that this may concern a more powerful version of the device, which, most likely, will be available only in the Middle Kingdom. In Europe, a slightly weaker and slightly cheaper model with 3 GB of RAM and 32 GB of internal memory may appear.
