HDMI vs. Component – What is the best for HDTV?

I see the question “What is better HDMI or component video for HDTV?” Asked several times in offices and elsewhere in the network. The answer to this question is “Well, it depends.” Before reading, in my opinion is better, I have to give a brief description of each.

HDMI is a pure digital signal as DVI with one exception. HDMI also carries digital audio cable itself. HDMI and DVI will give you a 100% exact copy of the original video. This is similar to the way in which the computer sends a file on the Internet at high speed in a purge (or digital).

While it is HDTV quality component video is analog, not digital. However, this is not necessarily a bad thing, as we shall see later in this article. Component video is compossed three separate RCA cables consisting of a luminance ( “Y” channel or “green”, which represents the overall brightness of the image), less bright red (Pr “” or “Red”, channel), and luminance less blue (the “lead” or “Blue”, cable) channel. Audo is also divided into two RCA cables usually colored red and white.

HDMI and component video output up to 1080p HDTV. This means that both are extremely well adapted to all types of devices in high definition. And most people will not notice the difference between the two, while maintaining a pure HDTV video signal.

So what is the best? Depends on the type of device you want to display the video signal and how the device converts the display from analog to digital. It also depends on your TV. This is a pure digital display like an LCD or a CRT screen as an analog.

Suppose you have an LCD display. This is a digital camera so pure common sense would say that HDMI is the best choice and, normally, this is certainly correct. However, if the output device has high-level image might have added digital artifacts that are displayed on your digital camera clean. For example, if you have a low-end upscaling DVD player you can see artifacts such as Blur more pixels, so that when viewing through HDMI on the large LCD screen. If this is the case then it might be better if you use component 480p and let your TV LCD upper limit to the scale bigger.

HDMI is more suitable, when both input and output devices are purely digital. A good example would be a computer or game console luxury. HDMI will give you a clearer picture of the Crips over the component. However, once again most people probably do not even notice it.

My opinion is that if the output device has both connections Try both and see for yourself that looks best for you. If your new digital camera, you probably prefer the first component, because you can see artifacts in signals of lower quality, like 480th analogue transmissions. Component tends to mask some of these artifacts as a function of how technology from analog to digital upscaling the output device is.

Another thing to consider is the length of cable you need. HDMI tends to require short distance in which the component cables can usually be very long. Component video is analog, can pick up interference, but unless the cable is of poor quality, is usually not a problem.

Decide if recording HD is a feature that would need them all, and if you do, identify if it is archiving for the long term or temporarily changing times. Transfer HD recording time you can use HD DVR (Digital Video Recorder, like TiVo) Service from cable and satellite.

If you really need to archive in HD resolution, three manufacturers of HD-VHS VCR (JVC, Marantz and Mitsubishi) have presented their models several years ago. Although this format is not as popular as regular VHS, you can still see some of these units in the market.

HD-VHS VCRs HD recording from their IEEE 1394 (FireWire) input only, which requires the development of the device (integrated HDTV or HD-STB) to have this production. Some TVs have integrated IEEE 1394, but the production capacity, or are they just for the camera.

DirecTV HD-top-box is not output IEEE 1394, Dish Network HD-decoder may be, even if the company once had for a few years ago to allow this regard, their model DVR 921, which has already abandoned.

Most pre-recorded HD movies Posted VHS use the D-Theater content protection, and are playable on JVC and Marantz compatible HD-VHS VCRs, but not on the Mitsubishi HD-DVD recorder.

Sony has introduced a $ 3800 Hi-Def DVD recorder in Japan in April 2003 with an HD satellite tuner, but not Hi-Def DVD standalone was introduced in the United States so far (December 2007), except showed some prototypes at electronics shows.

The only Hi-Def DVD drives were introduced in the United States blue-laser players, not recorders, and were introduced in early 2006 (by Toshiba HD DVD and Blu-ray player from Samsung a little ‘later).

If the filing is not required in HD quality, perhaps it could be sufficient for the moment to record HD content down-converted SD analog such as a VCR or DVD recorder to normal, but you will notice the difference when you compare the recording with SD ‘original HD Digital content.Recording Connections

When running tests viewer to decide whether your disposal for the session must be movable to adjust the display quality of the material (closer to the HDTV over backwards for NTSC), or perhaps it would be preferable to select a viewing position shall be a point of compromise between the two, enough to display both.

Watching from afar could see the stores, but may be physically limited by the size of your real part, and how your meeting, remember to use your room measures actual viewing distance for the test in the store and confirm to the house. One could conclude that it is better to reduce the size of the screen for all things or that you should consider a larger screen than you thought.

Assuming that you use the HDTV with a multi-channel audio (do not take into consideration all relevant legislation in this area), consider how moving a couple feet away from the screen image could have a sufficiently low audio sweet spot due to standing waves, the distance from the speaker or headset, and the limits of the room.

This test should probably be done separately in the test video for the store to determine the remote visualization, and audio test at home with your audio distance and confirmed that the video store. But the result can be very subjective as audio and video are all in the same room.

One could conclude that might be better to move the speakers so that the multi-channel sweet spot is the place of observation. Or you could start with your preferred sound sweet spot and adjust the screen size for HDTV viewing sweet spot coincides with the point of listening to the sound. If this is your case, you should know this in advance, before committing to a size of the display screen based solely on modeling.

If this is too complicated and you just want to keep things simple, with a certain atmosphere in the room, you must focus on the factors viewing this article.

While we’re on this topic, let me say that the use of small speakers to any TV (and small amps on TV) as an alternative to a channel center speaker surround missing on your system configuration is not recommended as a permanent home theater. The dialog and most of his film is a center channel, estimated about 60% of the soundtrack.

When using small TV amps / speakers in a home theater capability to handle strong steps would be exceeded (and distortion that occur), long before the G / D / amplifier audio system in the assumption that the sound system is more powerful the sound of television, as usual. The effect may be worse if the system does not have a subwoofer to redirect low frequencies from a small speaker center and its surroundings. The distortion on the center channel would affect the clarity of the dialog on the high mountain passes.

Furthermore, sounds that are panning side to side would have different timbre while switching between the speakers (from left to right TV Center) video accompanies the movement in this direction. Voices of people walking side by side are changing their tone center speaker input and the TV, as we move away from him.

Although these considerations are home theater, if the HDTV is becoming a center of your home theater then issues requiring attention, sooner or later. Plan for the installation of the front (L / C / R) speakers with matching timbre and size, and the plan for equal amplification of all three.

When viewing and comparing sets, check the menu on your TV and video controls are set at medium term (the contrast is usually set very high by most manufacturers, when groups of files), check the color might be changed by other client, set the color temperature as standard or 6500 Kelvin ( “warm” setting may render the image more red, cool environment more blue), switch off peak and best color, sharpness, then “Settings” lively etc.

There is no value in the televised display unless those adjustments have been made before, and even then, be aware that the side-by-side comparisons of depth are difficult to perform correctly if the sets are calibrated and the display is performed in a controlled environment light, the option is not available in most stores (back when CRT RPTV were more popular, making the convergence with the TV menu has been challenged by the sales staff).

Many HDTV demo done with images of colorful flowers. TV does not address the projection of slides, test with moving images. You may notice exaggerated jagged edges of diagonal lines or curves, pixelation errors, macro blocking, pixel-activity (such as marching ants), etc.

The TV itself might not necessarily be responsible for these errors, but is useful for learning to detect imperfections in the image and how to identify the possible source (if the STB for the HD cable / satellite / OTA / DVR, TV, broadcasting, digital compression, the limited bandwidth allocated for that HD signal, the signal strength on the way home, etc.).

Knowing the source of imperfection would also help with upgrades of the equipment as confirming the need to replace an HD set top box for cable / satellite / OTA / DVR, instead of replacing an HDTV and more expensive. Some Internet forums can help develop awareness of imaging to detect errors, or can confirm that you are experiencing is not connected to the device.

View the contents of the real origin of HDTV 1080i camcorders, like the HD-Net channels of content, but also the content of opinions emerged from films such as HBO and Showtime movie, which may help to discover how the film grain appears on a HDTV, if you like it or not. See also the content of ABC and ESPN HD to test the conversion of their 720p broadcast to 1080i / p native resolution of your TV, if that is the case (the conversion is carried out either integrated with the TV or HD-STB).

Show NTSC video sources of various horizontal resolutions (such as DVD, VHS, antenna, satellite, cable), notice effective conversion of content 480th progressive scan (with upscaling to 480p or 720p/1080i/p) and how treatment could be video affected if the 4×3 image is developed by Fashion TV. Evaluate whether the distance of the upconverted image is too remote, or you need to sit gaps tolerate possible image.

See the Hardware from regular satellite / cable. Their typical compression is known to worsen the image of swift action and an HDTV big screen could make it more clear the test with action, not a basketball game of golf.

If, after the combination of all these factors that you must move your sitting too far away from the screen for NTSC material, the longest distance he could spoil the effect of large widescreen display “expect a big screen TV, or cause to consider a smaller screen, or replace the service provider due to quality, more compression, etc. Maybe she should live with it, and time to be informed before buying the set.

Recognize the existence and purpose of different proportions and their relationship with Hollywood, DVD, Hi-Def 16×9 DVD and HDTV, and how do they differ from normal 4×3 aspect ratio of regular NTSC analog TV.

Begin to understand and accept the black bars, left / right or top of the pillars / black bands at the bottom, and in some extreme cases, including four in a time when the contents are black bars in picture and television adds two side the particular program / channel.

Many widescreen movies (ie 2.35:1) are wider frame of an HD 16×9 (1.78:1) and continue to show with bars from top to bottom letterbox / black to maintain the correct geometry image. A 4×3 TV (analog or digital) that show these bars even more.

Learning to recognize that even though the top / bottom black bars give the false impression that you’re missing part of the image above and below, you actually see the entire left / right content for the wider scene by the director in a 4×3 image can not be seen.

Understand that if you use methods of expansion for a 4×3 image to fill the 16×9 widescreen TV frames you change the geometry of images and objects in and also cut the content that overflows the banks of the TV picture.

Test mode for 4×3 TV image and capacity expansion flow. Mode expansion are not standard among manufacturers. Some TVs do not have the scrolling capability. The TV could have been made by a producer who has chosen the path of expansion that does not.

Some modes of extension can truncate the top of people’s minds on the big boys just above their eyes the image, or to make their bodies look too wide, or cut the content interesting bottom screen as subtitles of films, Bloomberg stock quotes, scores for ESPN, a tennis player who serves behind the baseline, or the location bar displays the NASCAR top edge of the image.

If TV is not 16×9 image scrolling capabilities to let you move an image 4×3 extended upwards or downwards, this would mean that, to see the hidden content of the top / bottom edges of the image will be obliged to consult the ‘image as a 4×3 with lateral clear that you dislike, and with the risk of side effects burning pillar prolonged listening on plasma panels.

Consider also that, if you choose to view images on a TV 4×3 16×9 with side-pillars, the size “of” the image diagonal is smaller than the size of the diagonal TV screen, and its impact can not be satisfactory as originally envisaged under the impression of 16×9 panoramic images. Believe that the diagonal 4×3 with side-pillars could be even lower than that of the old 4×3 TV.

Begin to educate your family about these issues, the aspect ratio, and shows some adjustments that might need to do to reduce the risk of damaging some plasma or CRT (if you have or can still get one such), when game play with both sides Black-pillars, and displaying the logos and fixed dozens of games for long periods of time.

To avoid burn-in effect of fixed objects on the images, some intelligent television stations are designed to move the whole image a few pixels at intervals in a way that is not perceived by the viewer. But many sets do not have this characteristic and which belongs to the owner to implement certain security procedures, such as using the regular mode of expansion, in order to avoid high contrast settings, etc.

Mode of expansion that are unacceptable, or the lack of scrolling capability, you may have the potential to eliminate some sets from your final list, regardless of how it might appear in HD. Test well in the shop.

If you go to a regular direct-view 25 “CRT TV tube similar to a much larger 65″ Digital Projection TV, beginning to recognize the compromises you might need to do some image quality for the size of the data on the screen during display content on NTSC analog HDTV in September

An HD television will find an improved version of a progressive analog NTSC 480th image, but because the original image is not so resolved, the image obtained after processing of the video might still be sufficient detail for pleasant viewing. Even more if the screen is too large, or seen too closely. The effect could be compared to surpass a photo that does not have enough picture elements. Image 4×3 could look even worse when you use the methods of expansion of the TV to fill a 16×9 screen and eliminate the black bars / columns.

It will continue to be for some broadcasts NTSC DTV is fully implemented in February 2009. And, as mentioned earlier, the cable companies have been postponed to 2012 by the FCC to make the transition to digital text to all subscribers, which means that for now the cable companies could continue to feed the analog subscribers 480th analogue channels.

Somehow, the extent of above 2012, approved by the FCC in 2007, is a relief for the cable companies and subscribers, and save both (for now) the extra cost of digital-to-digital converters analog and landing is necessary when a complete switch to digital channels.

Many 480th sources to an HDTV, including broadcast, videotape, laserdisc, DVD recordings, etc. that are based on the resolution NTSC, is, unfortunately, shows all the imperfections of the analog low-resolution source, and many others continue to do so for many years, especially if the new TV has a screen larger than what you are replacing.

Some new video processing technologies to drastically improve the sources of analogue images by interpolating additional pixels for the original image, but there is that much can be done to an image that does not have sufficient original resolution for large displays. Be prepared to do some testing with the NTSC analog programming sources before you buy. Do not buy a larger screen, if necessary, depending on how good the HDTV channels just look.

Imagine for a moment this scene, the game is already in you and you and your wife start watching HD wonderful, changing the HDTV channels at a station not, your wife is holding your breath for a second, and finally turns to you and you say, “Honey the older TV looked better, why pay so much to get a grainy picture?

The majority of ballots are sent by readers patrol truth, but I found myself with an advantage eNews times a day. Have published a link to a YouTube video that was apparently created by Best Buy to train its staff on the Samsung LED TVs. As I and many others have noted (including the New York Times), the name is misleading because it implies that this is a different display technology LCD TV. E ‘therefore instructive to see that Best Buy has told his employees to focus on this new set.

The main points raised in the video: image quality ultra-thin, eco-friendly, InfoLink Internet connection and a SoundBar. In all four a minute video, the coach on the screen says the word “LCD”, exactly twice. And in both cases, the context is ambiguous at best.

The first is approaching the end of the segment of image quality, the coach said: “This will give you the LED LCD 120Hz 3D effect.” Huh? First, there is a lot of jargon to cram into a sentence, and no, not television in 3D. Yes, you can get a 3D impression from some images, but not a 3D stereoscopic display. But we see what leads to this statement. it comes after discussing the “Clear Panel Display” feature: “There is no barrier between the LED and the front part of the configuration screen. This light shines through a better fate.” No barrier between the LED and the front of the screen? So we have the lights that are the image, right? No, in fact is an obstacle, the liquid crystal layer between the LED lights and the front of the screen are responsible for blocking the light so as to have a picture. Block the light No, no image.

This image of video training led by Samsung shows how design Clear Panel reflects the light of the room, especially on a black screen.

And for the record, the design of the panel clearly indicates that simply did not put on an anti-reflective coating or film as a top layer. This level should spread the light from the screen and slightly reducing the sharpness a bit ‘, but also reduce glare hard that you see on the screen of the video.

The other reference to “LCD” is the section in eco-friendly, where the state-trainer ‘you’ll be with about 40% less power than conventional LCD TV. “Okay, get partial credit may not even be misleading, saying,” With LCD TV, but adding the qualifier “traditional” does not make it clear that TV LED and LCD TV are both traditional. Actually, I think many people have could infer from this statement that the TV is not a LED LCD.

The bottom line is that at no time the coach say that the LED televisions are a new and improved LCD TV, or they replace fluorescent lamps with LED backlight. Most performance requirements are credible (even if a few stumbles as the 3D statement may raise some doubts), but it is clear that the authors of this video does not want to stress that this is actually the LCD televisions. And apparently this is the way Samsung and Best Buy staff wants to understand these televisions words.

This video is misleading? I leave you to decide for themselves when you watch the video. These Samsung TVs have some real performance advantages to offer, but I hope that these could be marketed without making it sound like he is a new technology that is not LCD. Not see the benefit of consumers, or in the long run, or Samsung or Best Buy.

According to sources, the movement of the Top 24 of the nation’s 25 newspapers is significantly diminished. In this age of Internet instant transmission of news when you want and on the topics you want to know, and with Craig’s List offering free ads in every state, it is not surprising that subscriptions are down Newpaper. But the Internet can keep for themselves the seeds for the survival of newspapers. The Group of dissemination, 76% of respondents would like to have their TV connected to the Internet. And now, Sharp has demonstrated a system that allows viewers to Japan to get their morning paper on the big screen.

According to a Tech-On, Sharp showed a service that allows subscribers to obtain the Mainichi Shimbun (Japan), patterns of Internet capable of Sharp LCD HDTV in water. You get only the first five pages of material, and advertising in the electronic version are different from those published, but the pages have the same format and you can zoom in to enlarge the text.

The press began as an experiment, and will be available free for the next six months. Sharp will demonstrate the system at the CEATEC exhibition next October 6 to 10, in Japan.

It ‘an interesting project because it could lead to a new source of revenue for the existing text. Presents the information as a family newspaper, rather than the presentation of type Helter Skelter of a web page. And going directly to an HDTV connected to the Internet without needing a separate computer, which makes it easily accessible to readers. I believe that the editors of newspapers across the United States experience demonstrates Sharp in Japan very closely and if it shows signs of success, we will probably see signs of here in a short time.

How big is your room? Probably not too big for his Gefen DVI-1600HD. This device is the professional level is excessive for most residential installations, but can perform an HDMI connection more than is normally possible. As up to two kilometers from her? The system is based on four lines of fiber optic cable. If you need to include compliance with a resolution of 1080p HDCP, then you will be limited to a mere 1000 feet.

The system is designed for digital signage and optical fiber transmission has the advantage of not being affected by electromagnetic interference. The same cable also carry audio and control as well.

So, unless your living room is the length of three football fields, you probably do not need this. But it is nice to know that there, in the case?

A new survey research firm NPD indicates that one of four U.S. households intend to buy a new TV in the next six months. Size and high resolution were the most important factors, according to the survey.

For those considering buying a new game, the average size for the proposed purchase of 40 “to 42″. According to NPD, the average price of this size, was $ 838 for the first three quarters of 2009. Is down 27% compared to the average of 1,150 dollars for the same period in 2008. While these lower prices are encouraging for the consumer, this means that even with unit sales growth, manufacturers of flat screen televisions can see their incomes stagnate or even decline.
