A Software Based Approach to Video Monitoring
Anupama Anantharaman - new Real-time content monitoring is a mission-critical operation for broadcasters, telecom, and satellite operators. Traditionally, service providers have used monitoring systems based on specialized hardware with a dedicated, fixed interface designed to monitor a specific number of video feeds. Yet, bespoke hardware solutions require a substantial amount of manpower, have a higher cost of ownership than software, and are inflexible.

Rethinking standards in the media world
Bruce Devlin It's actually a more difficult question than you think. When I ask the majority of engineers this question, I will get a technical answer. It will be something like "to be sure we meet the specification" or "to be sure we don't put bad signals on air" or "so that I don't get fired for getting loudness wrong"

Scopes, a creative trilogy
Paul Issacs The purpose of color correction is to fix any problems with exposure and color, ensuring the final image looks right. Color grading is used to set the mood by adjusting the colors of the video imagery to achieve a certain look or feel.

Audio
Pieter Schillebeeckx Audio monitoring has come a long way since its humble beginnings of a box with a speaker, a volume control and an analogue input. Today's high-end audio monitoring units boast an impressive array of I/O such as SDI, MADI, AES-3 and Analogue while offering a large amount of functionality such as accurate metering, loudness measurement, Dolby decoding, metadata analysis and video confidence monitoring. There is however a huge storm brewing in the world of broadcast in the form of video and audio over IP, which will turn everything upside down.

Test & Measurement: Ask the expert
Alan Wheable There are basically two different approaches to capturing the Eye Diagram from an SDI signal. These are real-time capture (employed by Real Time oscilloscopes) and signal subsampling (employed by Sampling oscilloscopes such as the Omnitek Ultra 4k Tool Box). All broadcast T&M equipment will use one of these approaches to create the Eye Diagram using a variety of proprietary techniques.

In media monitoring, as in medicine, a quick fix is not a cure
Simen Frostad A man is rushed to hospital with a suspected heart attack. The priorities of the medical team that treats him are clear: keep the patient alive, contain the damage to the heart as far as possible, stabilise the situation until the patient is out of danger. They work under the pressure of these immediate priorities, and with little or no information about the patients medical history to date.

AERO.soft - Bringing audio monitoring and processing into AoIP
Martin Dyster In the past, audio processing and monitoring required the purchasing of multiple, specialized hardware to support each function in the air chain. But now, thanks to the increase in the speed of Ethernet connectivity, and IT-based processing power, many of these same processes can be condensed and supported over IP. Audio in particular is making a move to the IP realm with the recent AES67 standard bringing interoperability between manufacturers. Even with this standardization, Audio over IP (AoIP) is still not being used to its maximum potential in the broadcast space.

Authoring and Monitoring for the emerging 3D immersive Broadcast Audio formats
Anthony Wilkins The world of broadcast audio is on the verge of a major revolution. Numerous 3D Immersive formats are under development and will find their way into the mainstream of broadcast production and distribution in the near future. Unlike the world of relatively constrained channel based coding as we are accustomed to (most commonly Left / Right for Stereo and Left / Centre / Right / Surround Left / Surround Right + LFE or Low Frequency Effects for surround), these new codecs will support more channels and/or object based audio coding. For the end consumer, there will be two major benefits from this new approach, a greater sense of involvement or immersion, and a degree of personalisation.

On-camera monitors for today and tomorrow
Paul Issacs Image quality is a central concern for users of any video product, so monitoring should be one of the foremost considerations for cinematographers and videographers. Along similar lines, the ability of consumer televisions and a range of personal devices to display increasingly better imagery has led to higher expectations of quality.

A soft shift in Monitoring Solutions
Craig Newbury The technology supporting the media industry is evolving at a furious pace, making system flexibility a critical characteristic of any new equipment or infrastructure investment. Broadcasters and other media companies must adapt quickly if they are to benefit from changing content creation, management, and delivery models, but they can't afford to purchase solutions that meet only immediate requirements, and not necessarily those of the future.

Confidence Monitoring in the Modern Broadcast Environment
Graham Taylor Monitoring equipment is often the last element considered in a broadcast system build, and getting its deployment just right is not always a top priority. However, most operations managers and broadcast engineers readily acknowledge the critical role that effective monitoring plays in making their jobs easier. This is especially true today, with broadcast networks growing ever more complex and relying on technologies that were not originally intended for the broadcast environment.

Singularity - QA and compliance monitoring in one box
Martin Dyster The task of maintaining loudness-compliant, high-quality delivery for broadcast audio is no longer a question of simply using ones ears. Audio channels produced for todays fast-paced productions come in embedded SDI workflow with streaming signals containing a mix of mono, stereo, surround, Dolby encoded and descriptive audio, as well as alternative mixes and multiple language tracks. Maintaining a quality audio track using this disparate mix of audio elements is one part of the QA equation facing broadcasters.

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.

This usually means there are any number of ways each camera lens combination could be producing images with minor are major signal level differences. If these level differences are not dealt with on-set or in post-production, they could lead the visually objectionable artefacts in 3D portrayal.
