Managing Technological Change
Alan Wheable Continual technological change in the broadcast and media industries can make it difficult to plan for the mid to long term. Typically, broadcasters and media organisation are still implementing the last set of changes to working practices when the next changes come along.

How to read Video Scopes
Larry Jordan# Understanding what video scopes tell us about our images is essential to creating great looking images; regardless of which video editing software you are using. In this article, I want to explain the basics of video scopes and how to read them.

Audio phase: Robin Palmer asks why it is wobbly?
Robin Palmer Phase meters and audio vectorscopes are to be found on most test kit involved with audio monitoring. This is important because left/right audio correlation problems between the channels will distort the stereo image and could degrade mono compatibility.

Wibbly Wobbly Waveforms
N/A The very first analytical electronic instrument, developed in the late 1890s, was the oscilloscope. This used a cathode ray tube (CRT) to paint a graph of voltage on the Y axis versus time on the X axis. Once television became a practical reality in the 1930s, the same instrument was applied to the video output from the camera and became the very useful waveform monitor.

Pointing out the right colours
N/A In the old days of PAL and NTSC analogue television, a vectorscope was an essential tool for examining chroma at every part for the programme production and transmission chain. This was because the colour information was carried as a phase and amplitude modulation which could be sensitive to a variety of transmission or recording non-linearities and problems. These could cause colour degradation or be completely wrong. In the digital age, colour information is carried in digits which do not usually get corrupted at each regeneration or link. So why would you want to look the chroma (colour information), portrayed on the same analogue style instrument?
