The real question is what is DTV. DTV is not to be confused with digital cable, satellite, Direct TV or Dish. DTV, digital television, is a new RF transmitting standard for over the air broadcasting which will replace NTSC, our old standard. Originally slated for January 2007, The DTV transition was riddled with filed extensions due to various reasons from capitol and financial market limitations to available crews and new equipment.

Can anyone give me an idea about the difference between NTSC and PAL system? Another thing I want to know about 1080p and 1080i.

For understanding PAL, you can start here: https://en.wikipedia.org/wiki/PAL. PAL, like NTSC, is an analog broadcasting standard.

The "i" in 1080 stands for "interlaced"; the "p" for progressive. The 1080 means there are 1080 lines of horizontal resolution.

Progressive scan is explained here: https://en.wikipedia.org/wiki/Progressive_scan. There is a link to an explanation of "interlaced video" in this article.
