SOURCE: Connecting Digital Decoder to Analogue TV.

This whole things is about converting the output of your digital decoder box to RF since your TV set only has an RF input

Lets look at the two main standards Composit and S-Video

1. if the output of your digital decoder is Composit you will need to convert it to RF using a Composit to RF converter.

RCA makes very small cheep ones that use about 9volts of power and can convert Composit into RF

2. if the output of your digital decoder is S-Video you will need an S-Video to RF converter

S-Video output is the newer standard but is essentialy the same as Composit and low cost.

Shalom ..

Go to http://vk3khb.gak.net.au/atv/chnlchrt.html#TV_Table

I went there and checked the details vs those appearing on my STB. Went through the manual channel search and changed the frequency to those on the above website. Now all channels work perfectly. I only bought this STB because my last one froze, it appears this one doesn't have the best auto search facility but with a bit of tinkering it will work for you!

1. Do I need any additional equipment to watch HDTV broadcasts on my HDTV-compatible TV?
In order to view over-the-air (OTA) HDTV broadcasts, you need to be within the reception area of a TV station broadcasting HDTV signals. Some TVs may require a set-top HDTV tuner and an external antenna to receive the broadcasts. Your cable or satellite provider may also offer HDTV channels as a part of their service, eliminating the need for a separate tuner. Please contact your local service provider to find out what kind of HDTV services they may offer.

2. What is CableCARD and how does it work?
HDTVs with CableCARD slots can accept a small card from your cable provider that allows you to receive standard definition and high definition digital broadcasts without a bulky set-top cable box. Please call your cable company to find out if they offer this service in your area.

HDMI, which stands for "High-Definition Multimedia Interface", is the consumer electronic industry's first connection capable of transmitting uncompressed digital audio/video signals. Components featuring HDMI can transmit both digital audio and video over one convenient cable, replacing the tangled mess that resides behind many home theater components. HDMI also offers improved quality over traditional analog connections thanks to all-digital transmission. Digital sources like DVDs and HDTV programming can now be transferred digitally from source to display without analog conversions that can degrade the original signal.

Unlike the HDMI interface, DVI only handles digital video. Through the use of an adapter, a DVI device can be connected to an HDMI device, but only video content can be transmitted. The audio signal would have to be transmitted through other methods such as analog RCA outputs or an optical digital output.

4. What's the difference between 720p and 1080i HDTV broadcasts? Does my CRT projection HDTV support both?
HDTV signals can be broadcast in either 720p and 1080i. It's up to the broadcaster which signal format to use, and both have their benefits. Our CRT projection HDTVs display 1080i signals in their native format. For 720p broadcasts, you can use the settings on your HDTV set-top tuner, cable box, or satellite tuner to convert a 720p signal into a 1080i signal that your TV can display.

Your widescreen TV has an aspect ratio of 16:9 (1.78:1), which is the aspect ratio of HDTV. However, movies are filmed at several different aspect ratios, including 2.35:1. Also referred to as "scope", 2.35:1 is a very panoramic aspect ratio that provides a wide field of view in the theater. Scope is much wider than your widescreen TV, so it still requires the use of letterboxing ("black bars") to fit the entire image on screen. Some TVs and DVD players have a zoom function that allows you to blow up the image so it fills the screen, but the sides of the image must be cropped in order to do so.

6. What will 4:3 broadcasts and DVDs look like on a widescreen TV?
There are multiple settings for adjusting the appearance of 4:3 material on Panasonic widescreen TVs. It can be viewed with black bars on the sides, preserving the way it was originally intended to be viewed. Some viewers find the black bars distracting, so they might prefer one of the stretch modes that lets you fill the entire TV screen with the image. One such mode is the JUST (justify) mode, which stretches only the outer portion of the picture while leaving the center untouched.

Hooked up to antenna did channel scan in air mode not getting any channels. Hooked up a Vizio tv to same antenna line and got all the locals. Maybe something wrong with the Sharp?


Make sure that Sharpe is set to over the air/antenna and not cable. There are more than one scan modes. http://files.sharpusa.com/Downloads/ForHome/HomeEntertainment/LCDTVs/Manuals/tel_man_LC42_46_52D65U.pdf

See page 14 in the link. It is easy to mis-configure the setup to not receive the over the air digital channels. The input must be set to digital and air in setup. The VHF are no longer available.

Hope this helps?

Where can I buy a digital tv tuner to replace the analog tuner in a DVDRHD04


Generally recording machines fitted with an analogue tuner can only continue to be used to record digital tv by using a digital set-top box.
It would not be practical or economic to remove the internal analogue tuner and replace it with a digital tuner unless the person is a highly skilled and experienced repairer.

Digital set-top boxes are available from all sorts of outlets at all sorts of prices. Many surplus boxes can be found at boot sales, garage or yard sales or charity shops at very low prices.

Most boxes have the minimum of connections and often offer only a scart output but some of the older, more expensive and usually better quality boxes also contained a UHF tuner in a similar way to the old vhs recorders so even older tv sets could be used with digital even though no scart input was fitted.

How do i connect my set top box to my digital tv


Ok, I am confused. How old is the TV? If new, hook the ariel directly into the tuner on the TV. The ATSM tuner in auto configure will identify and setup the channels with no need for a set top box. On old TV using an Analog Tuner will need a box. Antenna in goes to the antenna, antenna out goes to the F connector on the TV. Should be one coax connector on the TV. That is an F connector. Set the TV to channel 3 or 4 depending on what the switch is set on the back of the set top box.

I have an older Sharp Aquos TV - model # LC-32G4U. I am trying to connect a digital antenna but it doesn't work. Anyone know if I need a separate digital tuner for this TV? Or what else might be t


There is no difference between a "digital" and analog antenna. Either antenna will capture the signal. What you need is a digital converter box to convert the over air digital signal to the older analog type signal your TV needs. You connect the antenna to the digital converter box, and the digital converter box to the TV.
Several years ago, the US government forced peopel to buy digital converter boxes or newer TVs that could pick up the digital signal. Either get a digital converter box or a new TV.

Does my LC-13S2U have a digital tuner?


Going over you manual for the tv, it doesn't have a digital tuner.
You'll need a digital converter box for broadcast channels.
Indoor antenna will work. But, an outdoor antenna will work best for reception.
If you need a copy of your manual, you can download one with this link:
