The goal of digital video compression is to reduce bit rate by identifying and removing redundancies, while preserving picture quality.

In the analog video world, the picture resolution is expressed in lines per picture height (LPH) and reflects the losses caused by the vertical and horizontal

Learn how savings in bandwidth can be obtained by using color-difference signals.

Digital video is a method of representing the infinite variations of video signal levels inside a specified limit (e.g. 0mV to 700mV) as a limited number

Over many years, video equipment manufacturers have responded to the trend toward digital video by producing a large number of application-specific digital

The key to efficient compression is noise reduction prior to the compression stage. Michael Robin shows readers how noise adversely affects compression and reveals tips to remove it

Review key SMPTE and EBU standards for television systems and learn how they affect your station's systems

Compression is usually affected by removing video signal redundancies and unneccessary data.

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

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

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

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

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.

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

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

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