I have a standard non-flat TV. Whenever I watch a DVD the resolution seems twice as clear as regular TV, is that EDTV? Also my TV doesn't have slots for component cables, just for composite, is there some kind of adaptor for that?

It's quite simple. It boils down to resolution. Sound and aspect ratio is another benefit of HDTV, but not the biggest advantage.
SDTV is 480 interlaced lines (480i). EDTV is 480 progressive lines (480p). HDTV is 720 progressive (720p), 1080 interlaced (1080i) or 1080 progressive lines (1080p). Instead of going into detail between interlaced and progressive, you just need to know that progressive will present a cleaner picture (no jagged edges). Higher resolution, the clearer the picture is.
The reason why you see a difference is because you are receiving a cleaner signal from DVD. If you consider the distance and interference a signal has to go through to get to your house, it is understandable why a standard tv signal would look bad. On your TV, you are still seeing a 480i signal. Just a cleaner 480i signal.
If you compare cable tv and DVD, you will see less of a difference. Cable companies do many things to amplify and improve the broadcast.
Most standard tube tv's are native 480 interlaced resolution and only support that. It cannot support 480p, 720p or 1080i. If you want to get higher resolution and EDTV or HDTV support, you need to upgrade to a plasma, lcd or dlp tv. There is no point in downconverting anything to composite. Composite is going to always provide a horrible signal.

SD TV it the same picture as you would watch DVDs or satellite ,most tubes TVs out there are TVs with a digital tuner the edtvs can receive a more lines of info about 800 by 480 lines with a hd tuner and the HDTV receive the info of at least 1080 by 720 so your TV can be SD TV it doesn't have the inputs to receive ed or hd most people with older TVs that watch over the air broadcast will buy a converter box for around 200 to receive the digital broadcast

If your TV doesn't have connections for component cables it is an SDTV (Standard Television). You can not get the same quality picture from composite as from component (no matter what you use to convert component to composite, composite has a much lower bandwidth, which means lower resolution).
Usually:
SDTV has an aspect ratio of 4:3.
EDTV has an aspect ratio of 16:9 but is unable to natively display 720p or higher resolution.
HDTV has an aspect ratio of 16:9 and is capable of natively displaying at least 720p and sometimes 1080i or 1080p resolution.

RE:
What is the difference between SDTV, EDTV, and HDTV?

Standard definition television (SDTV) is a digital television (DTV) format that provides a picture quality similar to digital versatile disk (DVD).
EDTV generally refers to video with picture quality beyond what is broadcastable ... ( The maximum EDTV frame rate of 60p is not possible from a DVD. ...
HDTV is high definition television. While a number of high-definition television standards have been proposed or implemented on a limited basis, the current HDTV standards are defined in ITU-R BT.709 as 1080 active interlaced or progressive lines, or 720 progressive lines, using a 16:9 aspect ratio. The term "high-definition" can refer to the resolution specifications themselves, or more loosely to media capable of similar sharpness, such as photographic film.

HDTV has at least twice the lineal resolution of standard-definition television (SDTV), thus allowing much more detail to be shown compared to analog television or regular DVD. In addition, the technical standards for broadcasting HDTV are also able to handle 16:9 aspect ratio pictures without using letterboxing, thus further increasing the effective resolution for such content.

SD or Standard Definition = 480 lines of resoloution
ED or Enhanced Def = 576 lines of Resoloution (usually) but a simulated High Def picture
HD or High Def = 720 lines of resoloution
Also you need to know about I and P
The P stands for progessive and the i stands for Interlaced. Both of these refer to the refresh rate of a TV.
If you take out 10 lines from the TV, an interlaced or I would refresh like this, 1,3,5,7,9,2,4,6,8,10
where a progressive or P would refresh like this, 1,2,3,4,5,6,7,8,9,10 TWICE as fast as an Interlaced. P wins every time.
Your TV is what it is. It is an SD 480P and that is all it will be. To get HD you will need to upgrade TV's
