Why does a digital tuner for HDTV have a analog to digital converter?

The digital tuner also demodulates the normal analog broadcasting. The tuner outputs a analog composite video signal to Video Processing Chip. In that chip, there is a ADC to convert the analog to digital, then after procession, display the content on the screen

Does the sony grand wega KF-50WE610 have a digital tuner?
No, it doesn't. If a TV does have a Digital Tuner then it will say so in the menu.
Does the sony trinitron wega kv-36fs100 have a digital tuner?
No, this TV has an analog tuner. When it was built, it was thought that DVI was going to be the connection of choice for HDTV systems, so it has these inputs. It can be connected to HDTV tuners w ith a HDMI to DVI converter cable.
If you have a digital tv and an outdoor antennae do you need a converter box?
In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.
How can one watch TV for free without cable?
It depends.... 1. Buy an digital tv (Sdtv or Hdtv) plus an antenna. 2. Analog tv (if you have an older tv), buy a digital to analog converter box plus an antenna. 3. Analog tv and antenna connected to digital DVD or digital VCR.
I have my analog receiver hooked up properly but i can't get the main menu to show on tv all i get is snow on tv what do i need to do?
As of the DTV transition in June 2008, your tv and radio will no longer be able to receive analog signals of any kind. Some stations were running both analog and digital stations throughout the transition but now the only channels that are allowed to do so is public access stations (which run local programming, i.e. school events, etc.. NOT ABC, NBC, etc...) The only way for you to view programs now is to get a digital television, that includes standard definition (SDTV) and high definition (HDTV) with antenna, or you need to get a digital to analog converter box with antenna, or get cable or satellite service (cable companies are exempt from the transition but many cable companies have opted to switch to digital). If you have a digital tv (which most likely will have both an analog and digital tuner) or a converter box and you still see snow, then it either is not set up properly, or you do not have and antenna attached to it. Please keep in mind you do not need any sort of special antenna. What ever kind you have can be made to work with your set up. If you still need assistance please let me know. I was technical support specialist for the transition. Hope this helps.
Do you need a converter box if you have a HDTV and DTV antenna?
Yes, it is alright to use a converter box on an HDTV. Go to Input and change the settings from HDTV to regular television viewing and it should work fine after the television scans for programs.
How do you convert an analog TV to HDTV?
One can convert an analog TV to HDTV by using a set top box or digital analog tuner converter box. One does require a HD ready TV though to be able to watch the HD channels.

How can you get HDTV over the air broadcast on a HDTV monitor with a standard TV antenna?
Yes, you can use the old antenna. However, some new antennas are specially designed to better capture digital TV signals. And the direction, angle, distance, and type of digital signals in your area could influence your choice of antenna. HDTV is a picture format, not a signal format. Most likely a TV with an HDTV picture format already has a digital tuner (ATSC) rather than only an analog tuner (NTSC). However, if it is just a monitor, then you may have to attach a tuner to it, or attach a tuner to your computer, and the computer to the monitor. Actually, there is no such thing as an "HDTV" tuner. There are analog and digital tuners. All HDTV is digital, but not all digital is going to be HDTV. In Feb 2009 the U.S. Government has mandated that all broadcasters will cease transmitting in analog format and begin transmitting their signals over the air in digital format only. This signal requires an ATSC type tuner (digital) to demodulate the digital signal and display it on your television screen. All TVs manufactured for use in the U.S. from 1 Jan 2006 must have an ATSC tuner. Older TVs with the older style NTSC tuner (analog) will require a converter box to demodulate the digital signals.

When everything goes digital, how will I know if my television will work?
All televisions sold after March 1, 2007 include a digital tuner (by law) so you are good if you have bought a TV since then. If your television is labeled as �Integrated Digital Tuner,� �Digital Tuner Built-In,� �Digital Receiver,� �Digital Tuner,� �DTV,� �ATSC,� or �HDTV� then it has a built in device that will be fine after Feb. 17, 2009. If your television set is labeled as a �Digital Monitor� or �HDTV Monitor,� or as �Digital Ready� or �HDTV Ready,� this does not mean it actually contains a digital tuner. All this means is this TV is capable of handling the converter box. Thus, you still will likely need a separate set-top box which contains a digital tuner in order to view over-the-air digital programming.
Why would you have picure on video channel but not on tv channelswhat would cause this?
All analog tv stations are off the air. Your tuner is analog unless the device is a very late model. You might need a HDTV converter.
Are tivo's compatible with HD tv's?
Tivo's are compatible with HDTV with many combinations of hardware and performance. # Tivo's HDseries3 records and plays back HDTV signals for best HDTV experience. You need the HD signal from satellite, cable, or (antenna) channels. The series3 has the HDTV format NTSC tuner and is reverse compatible with the old analog ATSC tuner capabilities. # The FCC mandated that all DVDR'S manufactured after March 2007 be HDTV compatible. TIVO ended series2 production and responded with the series3. # Tivo series2 records and plays back the standard analog ATSC signal for non-HDTV viewing. Your HDTV must have an analog input capability or analog tuner to view the lower quality analog signal. You need the analog signal from your satellite, cable, or local broadcast (antenna) channels. Series2 devices only have the ATSC tuner. # Satellite and cable providers will promote the new HDTV format but will continue to provide the lower quality analog signals in their packages. You need want the HDTV package view HD quality programs. A series2 Tivo will only store and replay the lower quality analog signals. # Feb 2009 the analog signal channels will no longer be locally broadcast by antenna. The FCC is administering a program to provide each household a converter to modifying the HDTV signal to the lesser quality analog channels. You will need this converter to continue using the Tivo series2 with antenna supplied signals. The question then becomes, WILL TIVO SUPPORT THE SERIES 2 DEVICES WITH PROGRAM GUIDE INFORMATION?
Is there a cable to go from hd out laptop to rca jacks tv?
HDTV is digital, RCA jacks are composite. They're not compatible video formats. You'd need a digital to analog converter.
Why do you have to have to have a converter box for HDTV if you are a cable company subscriber?
If by converter box you mean a digital converter box, the type that are being subsidized by the government, you don't. If you mean a tuner box, it is because the cable line is transmitting data, and it has to be interpreted into a video signal your TV can use.
Is this TV broadcast HDTV ready?
