Resolution part 1: i vs. p what does it mean?

Resolution part 1: i vs. p what does it mean?

Have you ever heard you neighbor say I got a 1080 HDTV?

What does that mean? The 1080 they are referring to has to do with the resolution, but is it 1080i or 1080p there is a big difference. We have found that many people do not really understand whatresolution is and what the letters i and p mean.

What is Resolution?

Resolution is a measurement of how many pixels are used to make up the picture on your TV. Usually this is listed as a number followed by the letter i or p. The number stands for the number of  lines on a television screen from top to bottom. The letter i stands for interlaced and p stands for progressive. One way to visualize what interlaced means is to put your hands together in front of you with your fingers from each hand alternating.  This represents the picture you see on the television screen.  If you take one hand away and then when you bring that hand back in you remove the other hand and continue alternating you are mimicking what happens while watching a show that is interlaced. Obviously it is happening very fast and it is not something you usually notice.  So with an interlaced picture you have odd and even lines alternating which ones are displaying on your screen. For example if you are watching a picture with 1080i you are watching something with 540 lines on the screen at one time.

Interlaced vs. Progressive:

Progressive or p means that one line is progressively scanned on to the television at one time.  Thus back to our fingers demonstration you would only remove one finger at a time and then replace it while removing the next adjacent finger and so on down the line until you start over again.   So as you may be starting to realize you if you are watching something in 720p you are watching a picture with 720 lines on it at one time, where 1080i is only giving you 540 lines at one time.         

So does this make sense to you?  What this means is that 1080i actually is a lower resolution than 720p. We have been watching interlaced television all of our lives.  Standard definition television is 480 lines interlaced.  This is difference between interlaced and progressive is becoming more apparent because our televisions now have ability to display higher resolutions.

In order for anything to be considered high definition it must be 720p or 1080i. 

This obviously is a very simple representation as to the difference between interlaced and progressive, but it seems to be a way that most people can actually start to understand what the difference is.  We will go into more depth and what the difference means to you as a viewer next.    

Here is a list of some common resolutions:

  • 480i Standard Definition old analog television still found from service providers
  • 480p Enhanced Definition found on DVD
  • 720p High Definition found from over the air and service providers
  • 1080i High Definition found from over the air and service providers
  • 1080p High Definition found only in Blu-ray and Movie Downloads

Actually POTS (plain old television service) analog NTSC is 525 lines resolution, analog PAL and SECAM are 625 lines resolution. These are interlaced. 480i is the common digital SDTV (480i-576i range) broadcast resolution.

Good News to the Video calling app lovers. Google has announced the release of its new video calling App named Duo. Duo is coming up to take a strong stand in the market overtaking the already established Apps like FaceTime, Skype, Facebook messenger, Viber and whatsapp etc. Google has claimed that the new Duo App will work fine even on a weak data and low networks. http://duodownload.com/

Google Duo, a new video chat app that works exclusively on phones, is getting released today. I've been using it for about a week and I can tell you that it's fast, easy to use, and devoid of complicated bells and whistles. You tap on the face of the person you want to call, they answer, and you have a one-on-one video chat going. Nobody who uses this app can say that Google didn't achieve its goal of creating a video chat app that's relentlessly, explicitly designed solely for phones.Duo opens with a split-screen view of your front-facing camera and a group of recently dialed contacts -- it lets you see what you look like even before you place a call.

The name Duo comes from Google's desire to focus on one-to-one video calling. That's why there is no group calling function -- something Google Hangouts originally made famous. http://duodownload.com/download-duo-google-hd-video-calling-app-apk/

There is one feature in Duo that feels genuinely new: it's called "Knock Knock." When you receive a call on Android (it doesn't work on the iPhone), your entire screen starts showing the live video from your caller before you even answer. It lets you see who's calling — and lets the caller make funny faces to try to entice you to answer.

Video calling is the next best thing to being with someone in person, but too often it can be a frustrating or complicated experience. You shouldn’t have to worry about whether your call will connect, or if your friend is using the same type of device as you are. It’s no wonder that nearly half of us never make video calls on mobile

Duo is simple from start to finish. To get started, all you need is your phone number and you’ll be able to reach people in your phone’s contacts list. No separate account is required, so you can sign up in just a few steps. From there, you can instantly begin a video call with a single tap.
Fast and reliable
We all know how it feels when a call fails to connect or when video gets choppy. We’ve built Duo to be fast and reliable, so that video calls connect quickly and work well even on slower networks. Call quality adjusts to changing network conditions to keep you connected — http://duodownload.com/google-duo-download-iphones-ipads/ when bandwidth is limited, Duo will gracefully reduce the resolution to keep the call going smoothly. For video calls on the go, Duo will switch between Wi-Fi and cellular data automatically without dropping your call. You can start your call at home, and continue seamlessly even when you head out the door.

We designed Duo to feel warm and inviting, focused on just you and the person you’re calling. To make calls feel more like an invitation rather than an interruption, we created a feature in Duo http://duodownload.com/google-duo-download-for-samsung-galaxy-android-mobiles/ called Knock Knock which lets you see live video of your caller before you answer, giving you a sense of what they’re up to and why they want to chat. Knock Knock makes video calling more spontaneous and welcoming, helping you connect with the person before you even pick up.

My Talking Tom is a game very similar to the popular POU where the players will have to raise the cat Tom, giving him all the care that a nice cat like him needs.

The players will have to feed him by giving him his favorite food; play a lot of different games with him so that he remains active; and of course send him to bed on time so that he can rest. http://www.mytalkingtomdownload.org/2016/03/my-talking-tom-free-download.html Only this way you can make Tom grow up and turn him from a little kitten into a real cat.

In addition to doing all these actions, with My Talking Tom you will also be able to customize your cat. In total, there are more than one thousand different combinations with which you can give a unique touch to your nice kitten. http://www.mytalkingtomdownload.org/2016/07/talking-tom-cat-2-APK-free-download.html With My Talking Tom you will also be able to do what the Talking Tom Cat application traditionally did. That is to say, you can say any phrase and Tom will repeat it using his strange tone of voice.

My Talking Tom is an entertaining game that follows the same line as Pou and it will let the players take care of a virtual pet and try to punctually attend to all its needs. http://www.mytalkingtomdownload.org/ My Talking Tom was released in the year 2013 and this game app became a sensation with more than 11 million downloads worlwide and that to in a span of 10 days after its launch. whatever the games you love to play with cats in the real time, you can do the same with My Talking Tom.With over 350 million downloads, the worldwide talking phenomenon is a must-play. Don’t miss out on the fun. Talking Tom is back - bigger, better and funner! He’s moved to his own place and now has tons of new accessories. You can even play a fun mini game called Climber Tom. Nope, he’s not alone, his neighbor Ben is here to tease him too
