This article is a continuation of our March HDTV data multiplexing article. It will deal with audio data multiplexing in the horizontal ancillary data

Because the ATSC committee could not agree on supporting a single scanning format, North America is faced with a choice of 18 formats if we choose a 60Hz-related

MPEG editing North American (FCC) and inter national (ITU) spectrum management concerns resulted in the analog television on-air channel allocations and

Audio synchronization Analog audio is difficult to handle. There are frequency response problems, distortion problems (harmonic and intermodulation),

In the 17th century, two scientists devoted their time to the study of light: Isaac Newton and Christian Huyghens. While trying to fend off falling apples,

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

All source formats are transmitted using the same nominal 1.485Gb/s serial bit rate. The capacity for carrying ancillary data varies from format to format.

An ideal situation for large installations would be to incorporate EDH processors at every routing switcher input and output.

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

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

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

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

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

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
