Digital to analog converters

Sunday, May 11th, 2008

By now you have probably heard about the digital tv switchover deadline in February of 2009. In case you haven’t, head on over to http://www.dtv.gov/ to get the long story. The short story is that analog TV signals will be turned off as of February 17, 2009. If you get your TV using an antenna, then there is something you need to do to get ready. You can either buy a new TV with an ATSC tuner in it already or you can purchase a government subsidized digital to analog converter box. To get your $40 coupon head over to https://www.dtv2009.gov/.

Last friday I received my coupon in the mail. The coupon comes in the form of a prepaid credit card and you can use it at any store that sells approved converter boxes. I took mine over to Best Buy and picked up their Insignia branded converter box. This box is fairly basic providing one digital input, one RF output and a composite video output but the box is proving to be quite up to the task. The composite output allows you to get stereo sound (surround sound in fact) from the device and an improved picture over the RF connection. It also offers just the current program and the next program on it’s very simple program guide.

Now you might be thinking there is nothing wrong with the current system and that just couldn’t be further from the truth. Even though your old analog TV isn’t digital, the picture will be virtually perfect and in some cases better than you’d get if you had dish or cable. Audio too will be improved and if you have a surround sound system then any show that uses surround sound will be available to you in surround sound as well.

While the analog to digital switch over is a bit of a hassle the quality improvement is very much worth it. If you have any old TVs that are still in good shape and you don’t want to buy a new one then I strongly recommend going the converter route.

HDCP is pronounced HanDiCaP

I have decided, after a little bit of reading, that HDCP should hence forth be pronounced as, handicap.

Projector project is finished

Monday, May 7th, 2007

I’m calling the projector project itself officially finished. I’m really pleased with how the whole project turned out, especially for the price paid. Here’s a listing of everything I’ve gotten to make complete this project.

Projector: $380
Ceiling mount: $17
Blackout cloth: $40 (three pieces, two for window coverings and one for the actual screen)
Wood for the frame: Free, previous owner of the house left it here
Cabling: $85 (50′ VGA to md1, 50′ component, component cables for Wii)
ATSC HDTV card for computer: $25
Other misc parts including outlet box, plates etc: $10

Total: about $555

For under $600 I now essentially have a 90″ EDTV, not exactly HDTV but very close. I’m able to view over the air HDTV of all of the local stations, play DVDs and Wii on a fairly large screen. The HDTV content looks very good despite the projector only having a native resolution of 854×480.

Pullin’ cable and hookin’ it up

Monday, April 30th, 2007

This weekend, among other projects, I managed to get some wire pulled for the projector which is now mounted on the ceiling. The wires pulled include component, VGA/USB and romex for power to the projector. The last thing I need to get is get the new outlets in the ceiling tapped into an existing circuit and I can call my home theater project done for now.

The component cable is hooked into an old mechanical A/V switch and allows me to switch between my Wii and DVD player. The VGA cable is, of course, for hooking up to a computer. I ran this cable because I wanted a way to play downloaded video, pictures and because my laptop makes a better DVD player than our stand alone DVD player.

When everything is all said and done I’ll have some new pics posted to my gallery.

Projector and screen progress

Tuesday, April 17th, 2007

Made some great progress towards finishing up the home theater last night by building the frame for my screen. I based my screen frame around a howto located at this site. My frame does not use any support bracing to help save on the weight and honestly the wood could be straighter. Measuring 79×45, I’ll be able to get an absolute maximum size of 90″ diagonal when viewing “widescreen” formatted material. This also gives me a maximum of 74″ diagonal for regular 4:3 content. Not bad for a total project cost of about $600.

The projector is here, but now what about the screen?

Tuesday, April 3rd, 2007

Well I have the projector in my possession and now I’m working out how to setup a screen. Once in a while I’d bring home a projector from work and just project onto a white shade from our basement. I’d like to create a larger and more permanent screen rather than pull down the shade each time we want to use the projector. While the shade works, I’m limited in how wide I can go.

Over on avsforum.com I read about what they call BOC or black out cloth. It’s actually some cloth that goes behind drapes to cut out light. It has decent properties for acting as a projector screen, though it has hardly any gain and can dull up the image some. So far, despite what my wife thinks, I have minimal cash invested into my screen so far. I’d like to avoid having to buy a “real” screen because DIY is just more fun.

The problem I’m running into is that BOC doesn’t appear to roll up well, and I’d prefer being able to roll up the screen between uses. So it looks like I’ll need to create a rigid frame to put the BOC onto which is going to create a storage issue. I guess I should have thought of all this before I got the projector!

Infocus Screenplay 4805 DLP Home Theater Projector

Thursday, March 22nd, 2007

I pulled the trigger today on a Woot.com deal. I can’t believe I got wife approval but I managed to pick up a decent home theater projector for cheap. It’s an older design and is marked as refurbished but hopefully it treats me good.

Read on to see the specs if you’re interested.

Apparently I’m not the only one

Apparently I’m not the only one out there that things aspect ratio is important.

Aspect ratio

Wednesday, March 14th, 2007

Here’s something I don’t like but I see it everywhere. Widescreen TV’s (particularly flat panels) that stretch 4:3 content so the aspect ratio is off. I understand people want to “get the most out of their set” but it’s funny to me they picked up a nice hi-def TV only to display standard def content at an incorrect aspect ratio. One wonders if they got the TV for their improved picture quality or status.
