When sound is represented by an electrical signal, it can be changed in many ways.

New video compression technologies differ from the composite video concept. They use the MPEG-2 concept with all its permissible variations. The MPEG-2

Too many lines would be a waste and too few lines would make the raster line structure visible. A decision had to be made. Camera sampling and picture

Performance testing is carried out by feeding a test signal to the input and measuring the distortions of the signal obtained at the output. The term

The ATSC/DTV standard specifies two picture aspect ratios (4:3 and 16:9). The 4:3 aspect ratio formats are, respectively, 720480 and 640480. The 16:9

With the advent of color television, North America felt the need to alter the frame-repetition frequency. We still live with the consequences of this
