Document Summary
Digital television = any technology that uses digital techniques to provide advanced television services such as high definition television (hdtv), multiple standard definition televisions (sdtv) and other advanced features and services. Hdtv 1 signal allocated within 6 mhz spectrum. Sdtv 4 signals allocated within 6 mhz spectrum (multicasting) The more channels you have the lower the quality: 2. ** ntsc = the standardized video transmission format for analog (not enforced) The more lines, the sharper the resolution. Interlaced scanning = the frame is split into 2 portions (each is called a field and the fields are combined to form a frame : the odd numbered lines 1-1079, the even numbers lines 2-1080, ex: 1080i. Progressive scanning = sequential displays of all lines: all computer images, what technology is moving towards, ex: 1080p. Cliff effect = all or nothing picture and sound.
