Little Template Changes

I decided to get a little creative with PHP to save on some download time on the server and I took the entire Top 10 iTunes Song, Links, Blogs and took that and made it a dynamic part of the page and put it into a sql database so I can just edit that without having to change the entire template on the blog so part of the blog is now in PHP so that bring the total part of this page into PHP, mySQL, HTML, CSS, Javascript, XML and RSS all in use on the site =).

Anyways hope it works for everyone as long as you have IE 5.0+, Safari 1.2+, Firefox 0.7+, Netscape 6.0+, Opera (Any Version). Well it should work for all of them since it's done on my server end and nothing really to do with the end users. So I hope it works for everyone. =)

Anyways there is a play coming up Imrov Comedy Really March 12th if you would like to join me let me know I will save you a seat. Hope all is well. Sorry for the nerdness of this post but that's just how I am at times ;).

I got a little confused yesterday went over to a guys house and he has a Philips Rear Projection TV. He has a DirecTV HD Tuner, Samsung DVD Player the one that can upconvert the 480p of DVD to 1080i. He has them all hooked up through a Composite Video Switcher! This TV he had had 2 DVI Ports and a HDMI Port. He has this decent HDTV and all of the potential is wasted from a possible viewing of 1080i but he has it hooked up via composite for a max of 320i of resolution. I hate not working at Best Buy not being able to help the idiots who work there stop people from getting a great TV and not being able to hook it up properly but I don't blame them for not wanting to pay $100 for a 6' HDMI to DVI Monster Cable. But still you have a good TV why not use it to it's potential?

Anyways Rant Out.

I started to think most people have no idea what I am talking about so let me clarify here is a picture for me to work with.

Okay the White Plug in the Middle is called DVI it allows for an uncompressed video signal of up to 1080i which means 1080 lines of interlaced resolution which means that every time an image is drawn on the screen it redraws every other line each time it redraws the image which with the back of this Samsung DLP I am using has a refresh rate of approx 75hz so every frame which American TV is 24Framses Per Second the screen is redrawn 75 times per second so 24x75,000 is how many times the screen is updated per second at 1080 lines of resolution. But it only redraws every other line so it's doing about half the work each pass.

Standard HDTV resolutions are 480p/720p/1080i the newer LCoS Can do 1080p over HDMI but no source that I have found can output 1080p.

So he had his TV hooked up via Composite which are the Yellow Plugs which create a huge loss of quality. Because Color, B&W, Horizontal and Vertical are all sent down one cable which can cause for loss of quality when all that is fed down a low bandwith cable. There is SVIDEO which is the Plug which seperates Color, B&W, and Horizontal and Veritcal which will give you about a 60% improvement of quality because each bit of signal is on it's own cable basically. The Red, Green and Blue Plugs are Component which seperates Red, Blue, and Green the three basic colors of TV and Horizontal are transmitted over the Blue and Vertical on the Green for the standard HDTV use this and it can do HDTV in all resolutions except for 1080p. DVI is all Digital and no DaC is needed (Digital to Analog Conversion) which is required over all other types. HDMI is the latest and greatest which can do 1080p and Full Quality 8.1 Digital Surround Sound over one Cable but it's a little ahead of it's time which is awesome.

And this guy had all these inputs and used Composite the worst kind ever! He had a super bowl party with this. Ugh I would have cried with the horrible views of this TV. But I know way to much about this kinda thing and stuff like that bothers me if someone has an HDTV I always notice these kind of things such a bad habit I know but still you spend all that money on a TV and your going to show it off to me. Show it off properly hooked up Please. Then I will be jealous not laughing on the inside at you.

One clarification -- 75 Hz, or Hertz, is 75 times per second, not 75,000 times per second.

Yeah I have been thinking about that for a while now. But been a little busy to go change it. I was thinking Khz at the time. Some reason 44.1Khz for Audio has been running through my head. Thank you mystery person.
