Transition to Digital: Measuring the performance of audio devices and systems
By MICHAEL ROBIN published
When sound is represented by an electrical signal, it can be changed in many ways.
Transition to Digital
By MICHAEL ROBIN published
Resolution Many of the aspects of today's legacy television standards (SDTV) were developed through experiments carried out in the 1930s. They reflect
Digital standards defined
By MICHAEL ROBIN published
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
New delivery technologies
By MICHAEL ROBIN published
New video compression technologies differ from the composite video concept. They use the MPEG-2 concept with all its permissible variations. The MPEG-2
Video resolution
By MICHAEL ROBIN published
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
The digital resolution concepts
By MICHAEL ROBIN published
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.
Transition to Digital: Understanding Composite Analog Video
By MICHAEL ROBIN published
All color television systems use the principle of additive colors, with green, blue and red as primary colors.
Testing link performance
By MICHAEL ROBIN published
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
Getting from 4:3 to 16:9
By MICHAEL ROBIN published
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
Analog video noise
By MICHAEL ROBIN published
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
Measuring digital systems performance
By MICHAEL ROBIN published
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.
Audio multiplexing
By MICHAEL ROBIN published
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
Gamma correction
By MICHAEL ROBIN published
In this month's Transition to Digital, Michael Robin discusses the nonlinear relationship between a pixel's value and its displayed intensity on a color TV monitor
The digital video synchronization concept
By MICHAEL ROBIN published
The dominant SDTV digital video standard, Rec. 601, introduced a trailblazing concept of treating video signals.
