HDTV

HD is the term used to describe video formats that are higher resolution than standard definition. The formats include those with line counts of 720, 1035 and 1080

1080 is a reference to the number of lines used to create the image. Any video format that uses 1080 lines is HD although not all HD uses 1080 lines.

There are several formats that use 1080 lines and normally they are described as 1080i or 1080p, depending on how the image is generated. 1080p normally refers to an image with a full frame refresh rate of either 50 or 59.94Hz, twice that of 1080i.

The DTV Green Dish is a new antenna, partnered with a dish and forms a highly directional, high gain system.

It uses the parabolic reflector to focus terrestrial signals in a similar way to satellite dishes. It is claimed to improve reception with distant transmitters and the makers suggest it will be an improvement in all situations with guaranteed reception of all major channels. Buyers should probably have that kind of guarantee in writing before committing to the antenna. After all, it is breathtakingly expensive at $300.

The antenna is limited to receiving only channels that are broadcast on the terrestrial channels. Don't expect it to deliver the premium cable and satellite channels.

yeah.

The real reason to convert 1080i to 1080p is for archival purposes. In most cases, 1080i video is a program or film recorded off a television broadcast and "trapped" in your DVR (until a full hard drive forces deletion). However, those who still have a working Windows Media Center (hint: if you upgraded to Windows 10, you DON'T), are able to capture live 1080i broadcast video as playable files (*.WTV). These files can then be converted to the format of your choice. Herein lies the problem. Most (if not all) conversion software out there is unable to successfully deinterlace 1080i broadcast video. Certainly not in the most popular file formats (*.mp4, *.mkv, *.avi, *.mov, etc.) The result is noticeable motion blur. Hopefully one day the technology exists to do this without Final Cut Pro, After Effects and a whole lot of man hours at the professional edit bay. It will remain an issue until 1080p is adopted by the cable and satellite providers.

Yes you can provided that you have a additional sound system like a stereo receiver for the sound, if you a cable box/satellite receiver of and HDTV Receiver with either a HDMI or DVI port, (you'll need a converter cable for HDMI)

For most people, their old antenna will work just fine.

Don't let the people at the electronics store fool you, there is no such thing as an "HD antenna." There is nothing special that needs to be done to an antenna to receive HD signals. In fact, many of the antennas that are being marketed as "HD antennas" are inferior UHF-only antennas that receive a smaller set of signals than your old antenna.

However, some people who were barely receiving an analog signal may need to buy a better antenna. Also, if the location of the digital transmitter has changed or the signal strength of the TV station has changed, you may need to re-aim or replace your old antenna.

Simply plug the old antenna into the converter box and then plug the converter box into your old TV where the antenna used to go and you will be fine.

The converter box will tune in a digital station (some digital stations are HD, some are not) and convert the digital signal into an old-fashioned analog standard definition signal and feed it into your old analog TV.

You will not be able to watch shows in HD on your old analog TV, but you will be able to watch a version of the HD broadcast that has been converted into Standard Definition (SD) for you. You will be able to watch all of the digital stations including the HD ones but you will see them in Standard Definition. Standard Definition is 480i. Digital to Analog converter boxes receive all tv transmissions of 1080P , 1080i , 720P , 480P , 480i and coverts them ALL to 480i to watch on a standard definition NTSC Analog TV.

Brightness.

S-video carries two signals and requires two co-ax cables to connect them. There is no standard three wire S-video connection. Having said that, it is possible that a manufacturer has decided to provide a proprietary connection which is not recognized as a standard interface. The two screens of the conventional S-video co-ax may be linked together and so produce a three wire version. If that is the case, investigation will be needed to find out which is the screen, which is the luma signal and which is the chroma signal.

For a full answer, more detail will be needed. In the discussion area, add details of the appearance of both connectors, the manufacturer and model number of the two devices and a better answer is very likely.

To play a HD DVD you need a HD DVD player. A standard DVD player will not play a HD DVD, nor will a Blu-ray player.

HDMI is just a connection: it won't give your standard DVD player superpowers.

the correct answer is single direction

Yes, but to a very limited extent.

The most common indoor antennas generally may have rabbit ears, discs, and dials. The rabbit ears, contrary to popular belief, get the best directional signal when they are laid flat with both sides sticking straight out, perpindicular on a plane parallel with the earth, and perpindicular to the line from the broadcasting tower.

The length matters, too, but it depends upon which station is being received. You can set the length in the middle, to the stations you like best, or adjust it for optimum reception for each channel.

Loops should be arranged so that the plane that intersects the entire loop is perpindicular to the line from the broadcasting tower. Discs generally are plastic covered loops and should be arranged the same way.

Dials make some adjustment in the electrical properties of the antenna. Try each dial position, do a full channel scan, and mark the positions that pull in maximum channels. Then narrow it down from there by watching the channels for a while.

Now with that said, these rabbit-ear, loop, disc, dial antennas are not particularly directional because they do not make up for shadow signals that bounce off mountains and trees and buildings (whereas truly directional antennas, outdoor antennas and higher quality directional indoor antennas make compensations for these extra signals.). If the reception is still not satisfactory, then look for an antenna that is truly directional, omnidirectional, outdoor, or has a signal boost.

Tuning for digital transmissions is complicated because the picture comes in perfect, not at all, or perfect with sporadic corruptions, which you don't see right away when tuning. For more about selecting an antenna and tuning it, read on...

Going by outdoor antennas (which have definite directionality), antennas specifically marketed as directional have a gun shape to them that you just point. Other indoor antennas are specifically marketed as omni- or multi-directional. With these, there is no problem with aiming. Although they may not be the optimal antennas when all stations are in one direction, they are probably just fine (as I believe they are usually of higher quality than the uni-directional ones.) The information below may also be helpful for aiming and fine-tuning indoor antennas for digital TV reception: After finding the direction and distance of all the transmitting towers for digital television in the area (from the customized map at www.antennaweb.org), the next step would be to choose an antenna, hook it up, and aim it.

The antenna does not have to be "digital ready". Antennas are pretty much the same for analog and digital TV. (However, it is smart to know the characteristics of digital broadcasts in your area because of the difficulty in tuning to them.) You can start with whatever antenna you have, and if it does not work well enough, then research and buy a more appropriate one for your area. If you have no antenna at all, then try sticking the center wire tip of a cable TV cable into a potato or an orange--just to get an idea of the basic reception in your area. It will last a couple weeks until the vegetable dries out.

You need to be particularly choosy about your antenna if you want to receive channels 2-6, and to a lesser extent for channels 7-13. Channels 14-83 are the easiest to receive digitally, and most any antenna may do for those depending upon the distance and direction. If you are not satisfied with your reception on 2-13, but get 14-83 just fine, then you may want to just be patient rather than investing in an antenna: because of the large degree of difficulty with tuning these stations for digital transmissions, most stations are soon moving to the UHF band, channels 14-83. If you cannot wait, then focus on antennas designed specifically for both VHF and UHF (not only UHF in this case). In deciding whether you need a VHF antenna or not, you must realize that the stations have been renumbered and no longer represent the frequencies they broadcast on. For example, Digital channels 2-1, 2-2, 2-3, 2-4, 3-1, 5-1, 8-1, etc., are not necessarily broadcasted on VHF channels 2-8. To find out the broadcasted channels you must refer to a list like the one at www.antennaweb.org. (However, that website seems to only show the analog and dash-1 digital channels, not the dash-2 thru 5 channels, so another source must be sought).

If all the stations that you want are in the same direction from your house (within 20 degrees or so), then you can use a directional antenna and aim it right at the middle of the stations. Outdoor antennas come in 2 basic types, directional and multidirectional. Multidirectional antennas do not have to be aimed. To aim a directional outdoor antenna, follow the directions from the manufacturer. Indoor antennas are another story. They often come with no documentation, either in the box or on the manufacturer's website regarding tuning or aiming. They may only say turn the antenna until you get the best reception. This works fine for analog broadcasts because you can see the difference in quality when you turn the antenna. But digital broadcasts are different because the picture is either perfect or non-existent, or it corrupts at odd times and stops for a while (closed captioning may turn to gibberish, blocks of the picture turn colors or look like lower resolution, the screen freezes, and then a few seconds later it may restart). To tune an indoor antenna for digital reception the best method may be to try different positions of the rabbit ears, disc, and dial, and write them down methodically, doing a new complete scan for channels each time, and then count and write down how many channels are found each time. This is a better method for digital because the number of channels found is a better indication of signal quality than the visible picture quality. Be sure not to do manual scans because those function only to add new channels not to count the number of channels receivable. This method would work best when all towers are in one direction. If stations are broadcasting from different directions, then you should write down not only how many stations are detected, but which ones. Then your job is to come up with multiple settings combinations that get all the different stations you want at different times. After you have discovered them all, then do manual scans in each setting (if your TV has that function) to add all the stations. Then, keep a note close to your TV about which settings to use when actually watching each station. You may need only 2 settings to cover all your favorite stations (and in most areas only one setting will probably be satisfactory).

Since modern digital TVs have computers, one function really missing from them (exists in some models?) is a function to evaluate the tuning quality. Wouldn't it be great if your TV reported the signal quality it is receiving for each channel? I am not an engineer, but from what I know of the way digital TV works, it seems like such an easy function that I wonder if it is not already built in to TVs, but just not publicized. I am definitely looking for this function to appear soon.

In North America and Europe there are moves in progress to stop analog television broadcasts in the coming year or two. 2010 is the cut off year for the US and 2012 for the UK. By that time, all television broadcasting will be digital.

Older televisions do not have digital receivers and so will not be able to use digital broadcasts directly. There are a number of ways to continue receiving television even with an analog television. While it is not true of all retailers, some are using the changeover to drive sales of specific products that will generate the most profit for them. It is important that you do the research to find out what options are available to you and which channels will be received on each platform.

Here are some options for receiving digital television:

Digital terrestrial broadcasts can be received by a digital television (all new televisions in 2010 have digital receivers fitted) or they can be received with a digital set top box (known in the UK as a Freeview box). The available channels may vary from one region to another so you will need to find out your local service. A set top box can be bought for £20 in the UK and $30 or so in US stores.

Satellite receivers can be used (Direct TV among others in the US and Sky in the UK) Most packages require a subscription but there are free channels on satellite platforms. In the UK, Freesat is a publicly funded platform that offers subscription free services including HD channels.

The last option is cable. Virgin has most of the UK market for cable and there are numerous cable providers in America. Each has its own package of channels with a wide variety of prices.

The choice of platform and vendor is down to price and channel requirements but there is absolutely no requirement to have cable to continue receiving television broadcasts.

Y Pb Pr is a form of component video with three signals. Y is the brightness signal while Pb and Pr each carry color information. All three are required to produce a full color image and they do not carry audio. Audio will usually require a further two connectors for stereo audio.

No, only HDMI can transfer DTS HD Master Audio and Dolby True HD.

The resolution of the video determines how large it will be on the screen. If you have a video that is 1980x1080 pixels, it will fill up the whole screen.

PPT or Powerpoint files cannot be played on any television. You will need to convert the graphics of the file to still JPG photos, or AVI or MPEG video files.

The LCD takes much LESS energy than a CTR.

Hi,

If it's a newer TV, look for a small hole in the front of the cabinet by the controls. It's the reset button. Use a small ink pen or even a toothpick and give the button inside a little push. If it resets and clears up, your microprocessor had locked up. If it doesn't correct the problem, unplug the set for 15 minutes and then plug it in again. Wait a couple of minutes and then turn it on. If neither of these clear it up, it's time for a service call.

Hope this helps,

Well as length is increased the delay will increase because the signal takes longer to travel to the destination, but i don't know exactly how much delay would be added. Keeping in mind that the RF signal travels at 186,000 miles a second, you will never see or hear a delay.
