HDTV stands for High Definition Television. HDTV enhances the quality of the picture on your screen and the quality of the sound. In the future HDTV will allow the connectivity of computers and televisions. Some of the features of HDTV are:

• Higher picture sharpness

• Larger picture

• More colors

• Wider picture

• Multi-channel digital cd quality sound

Under the proposed HDTV standard pictures will have 6 times the resolution of current TV and it will be a full 60 frames per second temporal resolution which is twice the current NTSC images. Motion will be seen smooth and the picture will be clear enough to sit very close to a very large screen. The picture will be displayed in a panoramic 16:9 horizontal-to-vertical aspect ratio to be more like movies and add the feeling of realism to TV.
