Given history, the development of accepted standards for digital video could be a challenge. The author takes a look at standards bodies and the industry’s past standards

In the 1980s, many interested parties began developing concepts of advanced television, or HDTV, geared at reproducing superior-quality 16:9 aspect ratio

The world around us is analog. Our perception mechanism is also analog. Standard audio transducers, such as the microphone and the loudspeaker, are analog

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

Michael Robin's look at bit-serial video distribution focuses on techniques to move digital signals between devices and systems

The Audio Engineering Society (AES), together with the European Broadcasting Union (EBU), developed a digital audio transmission standard known as the

In a previous article, we discussed analog audio SNR concepts. As mentioned, the dynamic range is restricted at the top by clipping (THD 1 percent) and

The chosen television picture repetition rate is aimed at satisfying different requirements

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

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

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

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

The advent of digital processing of video signals has introduced a new twist in the concept of picture resolution. This article will analyze some of the implications.

There is no ITU counterpart of this standard because at present, ITU does not consider it as an HDTV format.

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

Getting digital video from an analog source sounds simple. It isn't, as author Michael Robin explains.
