Digital Television

Analog television will be switching to digital television by June 12, 2009. In this category, you can talk about the requirements of digital television, converter boxes, and reception, just to name a few topics.

Is anyone else having transmission whining with 2001 Olds Silh- They think it is in the thrust or bearing Need help from others who have had this problem.?

I have a 2001 Oldsmobile Silhouette minivan with 103,XXX miles. We just paid $1,728 to have the transmission completely rebuilt. Our transmission started whining and shifting hard from time to time about a month ago. I first had the transmission fluid and filter changed, thinking the filter might be clogged. The van was whining only once or twice a week in the beginning, but soon started doing it more often. It mostly made the noise when we were driving around town making frequent stops and starts. After taking the transmission apart, the shop found the front bearing was wore and the overdrive clutch hub was shot. They put in a complete overhaul kit, new clutches, bearing kit, and a total of 5 or 6 updates to fix common factory problems with this transmission. The updates will supposedly make this transmission better than it was from the factory. Time will tell.

Is it normal for your LCD TV to make crackling noises when you turn it off.?

If I understand the question correctly, I'm assuming that you've watched the TV for awhile before you turn it off and you hear pops and cracks for awhile afterwards.

If that's the case, then yes, it is normal. It's the plastic parts popping and cracking as they cool. Remember the basics? Heating causes things to expand and cooling causes them to contract. Hence, pops and cracks as the parts cool at different rates due th the densities of the different types of plastics used in the manufacturing of your set.

Can you have two freeview boxes on the same TV?

Yes, if you have 2 scart sockets to plug them into but it would be pointless as you only need one.

What channel is f x on bell?

It is not on Bell Yet hopefully it will be soon.

Can you still get a digital tv converter box coupon?

No. Way too late to get coupons. But you can order converter boxes online cheaper than in store.

Why has tv reception been changed to digital?

In digital there is a signal threshold below which dropout (pixelation) occurs. When an analogue signal degrades the picture just gets 'snowy'. However, digital reception which is running alongside analogue is at quite a low level to prevent interference with the analogue channels and appears more susceptible to weather interference. When the analogue signals are turned off the digital signal is boosted to give maximum coverage and will deliver a better service all round.

How can use lcd monitor as tv with dth set top box?

The decorder needs to have a VIDEO output, some do and some don't. Connect the video output to the tv's video input.

These connections might be the R G B connectors or a HDMI connectors, these will be the best to use.

Is the Mikomi 15LCD250 tv digital?

This is a low cost television with a digital tuner built in (depending on the region where it is sold) and has an HDMI input that supports up to 720 line resolution. It appears to not support 1080 line.

How do you hook up an old Sony Trinitron to a converter box if the TV has only two screws for rabbit ears and no other inputs?

Go to Radio shack and ask. I'm not sure what it's called, but a little device that one end attaches to the two screws for the rabbit ears on the TV and the other end you plug a coaxial cable that will enable you to plug into a VCR or converter box

How can you convert the digital to analog or analog to digital?

Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv

Are coupons for converter boxes free?

Yes. See the web links section of this question for a link to the website where you can apply for free converter box coupons.

Why did the government mandate TV to go completely digital by February 2009?

From http://www.dtv.gov/

An important benefit of the switch to all-digital broadcasting is that it will free up parts of the valuable broadcast spectrum for public safety communications (such as police, fire departments, and rescue squads). Also, some of the spectrum will be auctioned to companies that will be able to provide consumers with more advanced wireless services (such as wireless broadband).

Consumers also benefit because digital broadcasting allows stations to offer improved picture and sound quality, and digital is much more efficient than analog. For example, rather than being limited to providing one analog program, a broadcaster is able to offer a super sharp "high definition" (HD) digital program or multiple "standard definition" (SD) digital programs simultaneously through a process called "multicasting." Multicasting allows broadcast stations to offer several channels of digital programming at the same time, using the same amount of spectrum required for one analog program. So, for example, while a station broadcasting in analog on channel 7 is only able to offer viewers one program, a station broadcasting in digital on channel 7 can offer viewers one digital program on channel 7-1, a second digital program on channel 7-2, a third digital program on channel 7-3, and so on. This means more programming choices for viewers. Further, DTV can provide interactive video and data services that are not possible with analog technology.

I personaly believe that they do that to earn more money, I mean, i have no problem with them switching, but hey what do i know

How HD upconverter works?

The principle of an up converter is very simple: take a standard definition signal, examine each pixel of it and then calculate what each pixel on an HD signal would look like if the signal was HD. Making that simple process actually happen is rather more complicated. Very powerful signal processors are needed to study a block of pixels of the incoming signal. Typically, the block will be four or five pixels wide and high. The centre of the pixel block is the position of the new pixel to be created in the HD signal. The pixels of the original signal that are closest to the position of the new pixel have the most impact on the new pixel. The further away the original pixels are from the new pixel position, the less they affect the brightness and color of the new pixel. Once the original pixels are assessed and the new pixel has been defined and stored away, the process is then repeated for the next HD pixel. There is far more to the process than is described but that is the principle of up conversion. The additional processes are used to generate images without hard, ragged or jerky edges and mis-shaped detail in the new image. The techniques have been developed over several decades and were first used to convert North American signals to European and vice versa. Some thirty years on and the conversion quality has improved dramatically. Despite the advances, up conversion is not an exact science and is not a perfect process. It is important to remember that HD signals contain about 5 times as much information as SD signals. Putting an SD signal through an up converter does NOT increase the amount of detail in the image. In fact, an up converter will actually degrade the detail very slightly. Fortunately, when we watch an up converted signal, it is quite common that we get an impression of a better image than the SD original.

What is the best lcd TVs sale website?

As I am not allowed to answer this question with a website name, this is quite a difficult question. You should check out store sites (Best Buy, Sears etc) and check prices to compare.

Do you need a high definition TV if you have digital cable?

Using HD TVSome satellite and cable networks do broadcast 720p HD, at this stage there are no full 1080 HD broadcasts. You need to live in an area where this service is provded and you'll need to pay a subscription fee and you will need a digital receiver with an HDMI output to your TV.

Also, you can watch analog or non-HD digital programing on a HDTV. To enjoy the better resolution that HD offers, you need to get HD signals from somewere: Free HD broadcasts with an antenna, HD cable, HD satellite, HD/BluRay DVDs...

Can you get teletext on new digital or HD Flatscreen tv's?

In the US it's called captioning and it is required that all sets with screens over a certain size have this feature built in. Go into your VIDEO MENU and look for CLOSED CAPTION or just CC. You have to be watching a program that has captioning on it.
