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.

Why test and measurement is for real life, not just for engineers
Will Strauss# Thanks to its long-standing association with virtually incomprehensible acronyms, dark machine rooms and (lets face it) engineers with unruly beards, the subject of Test and Measurement (T&M) always gets a bit of bum rap.

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.

HD Camera Measurements. Getting the most out of your camera, Part 5
N/A Recap previous Parts: While the first parts covered the theory and actual measurements of white shading, setting up colorimetry, exposure, greyscale adjustments, alignment and matching of cameras using a waveform monitor, this final part is devoted to providing a better understanding of the displays used.

HD Camera Measurements and getting the most out of your camera, Part 3
N/A Parts 1 and 2 covered the theory and actual measurement of white shading, making sure that the camera non-linearities introduced by various different lens systems on a particular camera are compensated. In this issue, Part 3 will investigate setting up colourimetry and exposure as well greyscale adjustments using a waveform monitor.
