“Hi, I just downloaded a movie in AVI format with full HD 1080p resolution, and I wonder if I could convert it into a HDTV standard video for playing on High-definition TV or directly watch AVI movie on HDTV?”

Nowadays more and more people start to become fans of high-definition contents like a computer monitor or a television with a high-definition display. And along with the development of high-definition display comes high-definition video contents. If you have sources of high-definition videos, there are always ways for you to play them on high-definition screen (if you wouldn’t mind spending a little time to figure it out). This post would give you the guide to make full use of your high-definition AVI video and HDTV. You can convert AVI to MP4 as well.

Part 1: Introduction to AVI Format and the Concept of HDTV

The full name of AVI is Audio Video Interleaved. It is a multimedia container format introduced by Microsoft in 1992 as part of its Video for Windows software. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. One of the advantages of AVI format is that it can preserve high-quality video content. So high quality AVI format videos are very suitable for converting into HDTV videos or playing on TVs with high-definition screen.

HDTV is a television system providing an image resolution that is substantially higher than that of standard-definition television. HDTV can be transmitted in the formats below:

1080p: 1920*1080p:2,073,600 pixels per frame
1080i: 1920*1080i:1,036,800 pixels per field or 2,073,600 pixels per frame
720p: 1280×720p: 921,600 pixels per frame

The letter “p” here stands for progressive scan, while “i” indicates interlaced.

When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television).
