The year was 1948, 20 years after Harry Nyquist wrote his article Certain Topics in Telegraph Transmission Theory, in which the Nyquist sampling principles

The most important use of the ancillary data space is for the insertion of audio signals accompanying the video signal

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

The problem is compounded by the virtual impossibility of achieving a common frame rate. Because the ATSC committee could not agree on supporting a single

Resolution Many of the aspects of today's legacy television standards (SDTV) were developed through experiments carried out in the 1930s. They reflect

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

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

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

All color television systems use the principle of additive colors, with green, blue and red as primary colors.

Combining multiple audio channels into a single stream is called multiplexing. It’s complex and requires careful planning. However, there are many solutions available, which the author reviews

All systems have noise and analog noise. In this month's Transition to Digital, Michael Robin helps readers understand the difference and where to look for the causes

The dominant SDTV digital video standard, Rec. 601, introduced a trailblazing concept of treating video signals.

A look at the bit-serial digital signal distribution concept – the reasons behind its development and use, and methods of testing the signals, including the EDH concept and the SDI check field.

Michael Robin explains how a signal area is created and the critical steps it takes to ensure that the signal isn't degraded as it passes through a broadcast or post facility
