720p vs 1080i HDTV

720p vs. 1080th is worth worrying about? Yes and no. If you are a consumer looking for a new TV, you are welcome to skip the debate because every 1080th vs. 720p TV which is described as HDTV or HDTV Ready is required to support both formats.

Note: You must keep in mind though that most TVs have 1080i support more than 1080 lines and so scale down 1,080 signal. This is not a big problem, so reduced as 1080i is far ahead of a regular NTSC signal. TheIt 'important to remember that more expensive HDTVs tend better scalers than cheaper, and this can be a problem.

HDTV

For broadcasters, is a hot topic. Should send 1080 interlaced lines or 720 lines progressive scan video? They could only send two signals, one in each format, but that would make a great deal of bandwidth and will win very expensive for very little use.

To answer your question, it is important to understand the difference between720p vs. 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on the screen for 1/30th of a second. This is known as progressive scan (hence the 'p') the quality is like watching 30 photographic images per second on TV. A 1080i signal comprises 1080 horizontal lines but all lines are not displayed on the screen simultaneously. Instead, they are interlaced (hence the 'i'), meaning that all other lines for 1/60th of a second and then the alternate lines are displayeddisplayed for 1/60th of a second. Thus, the frame rate is still 30 frames per second, but each image is divided into two camps, which then makes your brain unconsciously.

Most of the time the plot works well, but for fast moving images like sports such as baseball and hockey may have problems that cause an effect like "stepping" on the screen. Progressive scan signals do not have this problem and better suited to the sport.

ESPN leads this way:'Progressive scan technology produces better images for rapidly moving in the direction of sports television. In a nutshell, has recorded more than 104 mph fastballs in baseball and 120 mph shots on goal in hockey, line by line basis of progressive scan technology inherent fast action of sports. For ESPN, progressive scan technology makes perfect sense. "

Bottom line? For us as consumers 720p vs 1080i is not worth discussion, so you can relax and focus on all otherCriteria of the list when you buy your next HDTV.

Buying an HDTV - The 5 basic steps

Shopping for a new HDTV set can be confusing and intimidating, but if you break the process into smaller parts, begin to make sense. The most important factors to consider:
Budget Range Screen Size Style (plasma, LCD, etc.) Specific use Options
Budget Range

First things first. HDTVs costs are more closely related to the size of the screen, but also the quality, brand and image display. You need to read the reviews of individual setsFor full details, but here's a general idea of ​​what you get in every price range:

HDTV

Less than $ 500: 20-inch and smaller LCD, HD Ready (no tuner) HDTVs. 15-inch integrated HDTV tuner. You might find some up to 27 cm in some brands, like ViewSonic and Olevi.

$ 500 to $ 1000: 32-inch and smaller LCD, integrated HDTV tuner, 50 inch and smaller DLP HDTVs.

$ 1000 and $ 2000: 46-inch and smaller LCD, 50 inch and smaller plasma and 65-inch and smaller DLP HDTV.

$ 2000 to $ 4000: 52-inch and smaller LCD, 60 inch and smaller plasma and 75-inch and smaller DLP HDTVs.

Another thing to consider is that you can find great discounts on last year's models. HDTV technology is updating all the time, as computer technology. If you can not do with the latest technology, you can find some incredible deals discount-40 percent, or more, equal to only 18 months of age.

Screen Size

The right sizeHDTV> for your viewing space is important. In the old days was the right size of the largest TV that you could afford it, but today many people can a television so big that it dominates the view, make room, and are forced to stand so close that defects in the pixels of the screen, or individual are visible.

Another problem with sitting too close to a large screen HDTV is that your eyes will be turned back and forth across the screen, just as if it were a tennis gameCenter Court This rapid eye movement you become dizzy and give you headaches.

First on the site, where you can watch TV watching, and measure the distance from the TV screen at the center of your couch, beanbag, log, or anything else you sit. This distance should be 2 to 4 times the size of the screen. So, a 24-inch series would be good for the display from 4 to 8 meters, a 50-inch series would be good for a range of 8 to 16 meters, and a set of 60 inches, it would be good for 1020 meters away.

Display Style

The most popular types of flat-screen HDTV these days are LCD, plasma and DLP. CRT TVs are still available, and usually have a great picture, but the largest CRTs are extremely heavy and bulky. It slowly loses the pot Profile technology.

LCD stands for Liquid Crystal Display, and is the same type of computer screen in most new monitors used (you're probably looking at an LCD now), mobile phones, and manyother devices. LCD work best if you want a medium or small, need a more lightweight, or watch television in a well lit room.

Plasma televisions have a sheet of glass (unlike plastic LCD contrast) with an ionized gas trapped behind the emergence of an image when stimulated by electrical charges. Plasma TVs have a slight advantage over LCD in terms of image quality, especially when viewed from an angle as possible, but to have more screen brightness in bright sunlight.

DLP stands for Digital Light Processing. ThisSet to use tiny oscillating mirrors behind the screen to create an image. September DLP rear projection televisions are technically, but they are generally quite flat. They are cheaper than LCD and plasma in larger sizes, but often are a bit 'too heavy and bulky to hang on a wall.

Specific use

What do you do with your HDTV? You, sports fan or player you like movies? Different types of sets are ideal for slightly different things.

DLP TV are often very brightshows, but can lose detail in very dark scenes. This makes them ideal for shooting sports, news and external, but not so good for movies with lots of dark images. Plasma TVs have a great picture, and still look good when viewed from a wide angle no darkening or color change. However, a room with many windows, problems with glare on the plasma glass panel to be established. LCD TVs are much brighter in bright light, so are suitable for daytime viewing in lighted rooms. In a livelylit room, LCD TV may actually look better than a good plasma TV. LCD and better resolution, the sharper in the middle is the size, in order to use the ideal as additional monitor for your computer.

Options

All high-definition televisions with a slightly different package of features to come. A tuner is required to receive over-the-air broadcasts. Because they add costs, and many people only their high-definition televisions for watching cable, satellite, DVD, video games or other computer input devices, are not always included. ViewIntegrated ATSC tuner for, or buy an external tuner to receive over-the-air broadcasts.

Good speakers are nice to have an integrated HDTV. But if the sound quality is really important to you, you are better off with external speakers for high quality.

Links are important. You want at least 2 HDMI inputs for connecting to a cable box, DVR or DVD player. Other types of connections like component and S-Video cable is useful if you want externalComponents to use these cables. And if you want to use your HDTV with a digital camera, you need a USB port or memory card.

But it's really worth buying an HD-ready? The answer is yes. This is not because a lot of people will buy, though, because most TV shows and movies are produced in this format.

HDTV

In order to make the most of your HD-ready TV, you need to do some things. You mustConnect the components together, make some adjustments in the definition panel, and then a high definition signal.

If you have problems, read the manual, because this is what there for themselves. You can give, unfortunately, not all the answers, but trying a few things on their own and maybe do some research to find, you get the hang of it.

For those not too confident about how to configure the HD-ready TV, you can always ask for help from a professional to do the job forThem.

There are three ways to get a signal to a HD Ready TV using a cable, antenna or satellite. How to get a signal you are still for the message, read on to see how the work with the different methods.

If you get a signal through an antenna, external antenna, you can purchase a freestanding HDTV tuner HDTV also known as a receiver or ATSC tuner and ATSC a. If this is done via cable, you need an HD-Top boxes that can be rented or purchased from your cable company.

HDTV Bandwidth Management

Many people, especially those with satellite TV receivers have heard of MPEG. MPEG is a standard to reduce the size of the video signal so that it can be easily transferred. This is known as a "signal compression. Compressed Digital Video (CDV) is comparable to using MP3 files for music. This makes the file smaller without damaging it, so it takes less time to download (less bandwidth), and other tracks are stored on the player.

CDV reduces the bandwidth of the signal Requirements for a TV signal for transmission over the Internet, DVD, cable or satellite allows. This is necessary because an uncompressed video signal is very large. high-resolution files are much larger than the files in standard definition.

HDTV

A standard-definition DVD format movie file is about 3 GB per hour. An uncompressed 1280 X 720 (HDTV) file size is over 150 GB / hour. An uncompressed 1920 X 1080 (HDTV) file size is about 350 GB per hour. An MPEG-2 (CDV)HDTV> file is about 9 GB / hour. An MPEG-4 (CDV) HDTV file size is about 5 GB / hour.

The early use of CDV (for standard definition programming) was discovered by the satellite TV companies DirecTV and Dish Network.

CDV is the process of disposing of data for information that would be invisible to the viewer. However, too CDV significantly distort the output. data is a high level of CDV, most will be discarded.Dispose is too much, and the distortion is very surprising.

CDV is a compromise between file size and image quality. CDV is working on neighborhoods called pixel macro block. The CDV only the changes in these blocks. This method works well if the video is primarily static images as text.

In a basketball game when Kobe gets to the basket, the more pixels change from one image to another. If this happens, the video compression algorithm work harder. The image qualityafter compression depends on the complexity and predictability of the images.

CDV is the most common standards are written by the Moving Picture Experts Group (MPEG). The application of CDV is an intensive on-screen computer, but decompression (release of CDV) to the MPEG video data is much less difficult. A C-Cube real-time MPEG-1 video encoder with 8 custom processor chip sold for $ 120,000.

MPEG standards are heard by anyone. Several companies and researchers haveMPEG patents, but do not pay a license fee to use the MPEG technology.

DVD and Blu-ray have CDV are used in the process of burning (Blu-ray Disc has sufficient capacity that the CDV is not aggressive, so do not add significant distortion). algorithms are high-definition video with little CDV for video post-production work, but still uses this huge file, and therefore only rarely for distributing video.

There are several standard MPEGused, but only three are commonly used for distribution of commercial films:

MPEG-1

MPEG-1 was the first widespread video (and audio) standard CDV. MP3 is short for "MPEG-1 Audio Layer 3". MPEG-1 supports a screen resolution of 352 x 240 at 30 fps (frames per second). And 'the standard for CDV motion picture (and sound). This rule has found its roots in the CD-ROM video applications and is popular for video on the Internet (. MpgFiles).

MPEG-2

MPEG-2 video resolutions supported by 720 x 480 1280 x 720 at 60 FPS. MPEG-2 is capable of both high-definition TV and HDTV standard. The MPEG-2 standard is also used to store data on a DVD. This is the algorithm of DirecTV Dish Network uses.

MPEG-2 is the standard that is based on boxes, digital television set-top DVD and CDV. It 's based on MPEG-1, but modified for use by digital television. Various algorithms have beendeveloped and integrated into the standard. MPEG-2 is ideal for HDTV resolution and bit rate prices. With this technique, video data CDV 15 to 25 times while still compressed image quality to be a high value.

MPEG-4

This standard is the future standard VCD, which provides HDTV services will almost certainly be the majority. These include AT & T, DirecTV and Dish Network. A number of cable operatorsMPEG-4 has also launched studies. This standard was originally designed for the Internet. individual objects within a scene are recorded separately. This is very efficient.

The transition to MPEG-4 is the satellite companies are not designed to improve image quality, but because this algorithm is much more efficient. An-2-band channel of HDTV MPEG uses six standard definition TV channels, MPEG-4 HD channels only consume the bandwidth of the three standard-definitionTV channels. MPEG-4 uses half the bandwidth of MPEG-2, and so the service provider can offer twice the number of channels.

OpenCable Application Platform (OCAP)

Consumers can now purchase their own cable box / DVR combo at the electronics retailer. OCAP is to provide a way for cable operators and other service providers for interactive services, such as a PC. This allows American Idol voters cast their vote with the remote control for their employmentTV.

Consumers want their HDTV, and service providers that offer the program to flourish. MPEG-4 is the best option and cheaper for cable operators and other service providers.
