Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual mediaVideo can be interlaced or progressive.Interlacing was invented as a way to reduce flicker in early mechanical and CRT video displays without increasing the number of complete frames per second, which would have sacrificed image detail to remain within the limitations of a narrow bandwidth. The horizontal scan lines of each complete frame are treated as if numbered consecutively, and captured as two fields: an odd field (upper field) consisting of the odd-numbered lines and an even field (lower field) consisting of the even-numbered lines.Analog display devices reproduce each frame in the same way, effectively doubling the frame rate as far as perceptible overall flicker is concerned. When the image capture device acquires the fields one at a time, rather than dividing up a complete frame after it is captured, the frame rate for motion is effectively doubled as well, resulting in smoother, more lifelike reproduction (although with halved detail) of rapidly moving parts of the image when viewed on an interlaced CRT display, but the display of such a signal on a progressive scan device is problematic.NTSC, PAL and SECAM are interlaced formats. Abbreviated video resolution specifications often include an i to indicate interlacing. For example, PAL video format is often specified as 576i50, where 576 indicates the total number of horizontal scan lines, i indicates interlacing, and 50 indicates 50 fields (half-frames) per second.In progressive scan systems, each refresh period updates all scan lines in each frame in sequence. When displaying a natively progressive broadcast or recorded signal, the result is optimum spatial resolution of both the stationary and moving parts of the image. When displaying a natively interlaced signal, however, overall spatial resolution is degraded by simple line doubling—artifacts such as flickering or "comb" effects in moving parts of the image appear unless special signal processing eliminates them. A procedure known as deinterlacing can optimize the display of an interlaced video signal from an analog, DVD or satellite source on a progressive scan device such as an LCD Television, digital video projector or plasma panel. Deinterlacing cannot, however, produce video quality that is equivalent to true progressive scan source material.. [source: wikipedia]

How To View A Private Video On YouTube and Private Videos Explained
In my involvement in the YouTube community I’m surprised how many questions about Private YouTube videos arise. I thought this was a straightforward feature but on closer inspection I can see how people become confused. In this article I’ll answer common questions and explain Private Videos and the options that surround them. Firstly here’s how to make a video private on YouTube. Navigate to Creator Studio>Video Manager> Find the video you wish to make private (or Public or Unlisted) > Edit > Info and Settings > and then on the Basic Settings tab you can select the status of the video from the dropdown on the right: youtube private video dropdown Now back to your questions. 5 questions about Private YouTube videos answered How can I bypass YouTube private video? Simple answer. You Can’t. The channel manager has set the video to Private for a reason and doesn’t want you to see it. YouTube has made it impossible to bypass the Private Video function and rightly so. See answer 2 to see what you need to be able to view a private video. How can I share a YouTube video privately? Once you’ve set your video to Private there’s a box where you can add the email addresses of people you wish to see the video. Enter the addresses separated by a comma and hit Share > Save Changes. They will then be emailed a link through which they can view the video (see answer 3 for more details on this process). As this system is powered by Google+ you can add Circles to the permission list before saving it and everyone in that circle will receive the viewing link. share private youtube video I’ve given someone permission to access a private video but they can’t view it – what’s wrong? The Private video function is far from perfect and there are a few things you need to know to avoid trouble. Even if someone has been given permission the only way they can watch the video is through the link in the email they’ve been sent so sending them just the link won’t work. To give someone the best chance of actually receiving the email, follow these steps: Try and make sure the recipient is using a Gmail based address. This shouldn’t be necessary but in reality it helps. If the viewer is using the Tabbed Gmail layout tell them to check their Social tab for the notification. The notification will be sent from noreply@youtube.com so get them to add this address to their contacts to avoid it going into spam. What is the difference between an Unlisted and Private video? I’ve already outlined the steps needed to watch a Private video, an Unlisted Video is less tightly controlled. An Unlisted video simply means that anyone with the link can watch the video but it’s not discoverable by other means such as Search, Suggested Videos and will not appear in Subscriber’s feeds. Unlisted videos can however be embedded. Only make a video Unlisted if you’re happy with anyone seeing it because the link can be shared easily as with a Public video. If there’s sensitive material in the video always play safe and make it Private. Can content ID work on a private video? Yes it can and it will. I see many beginners posting this question because they’ve received a copyright strike against a Private video and don’t know how or why this can happen. Manual takedowns/disputes by copyright holders make up only a tiny fraction of copyright claims and the majority are undertaken by YouTube’s automated system Content ID. Automated being the key word here. The system scans all uploads, Public, Private and Unlisted to compare against reference files so just because a video is not viewable by humans doesn’t make it immune to Content ID. As always I suggest staying squeaky clean and only uploading content you have 100% exclusive rights to, have express permission to use or are certain that you’re complying to appropriate fair use laws. While there is a seemingly endless number of companies issuing auto insurance policies these days, there are really just two ways to buy car insurance: You can purchase a policy in-person through an agent -- a licensed individual who sells policies on behalf of one or more insurance companies -- or you can buy directly from an insurer via Web site or telephone.Buying car insurance online still accounts for a relatively small portion of total auto insurance sales, but it's increasing in popularity. According to a 2011 survey by the Internet marketing research company ComScore, just 20 percent of new auto insurance policies were purchased online, compared to 43 percent purchased from an agent. However, the number of online purchases represents an increase of 5 percent from just two years earlier, while the number of agent purchases represents a 6 percent decline. Additionally, a 2011 survey by J.D. Power and Associates showed that 54 percent of new auto insurance owners applied for a rate quote online, the first time this has happened for a majority of respondents [source: Insurance Information Institute].
