When you turn up the gain on virtually any microphone preamplifier, it sounds noisy. Why is this? Before you blame the amplifier, let’s look more closely at this common phenomenon.
In this series of articles, we will explain broadcasting for IT engineers. Television is an illusion, there are no moving pictures and todays broadcast formats are heavily dependent on decisions engineers made in the 1930’s and 1940’s. In this article we look at how to represent time in 59.94i frame sys…
The Human Auditory System evolved as a survival tool and one of the vital functions of hearing is to establish where a source of sound is located. The oldest aspects of human hearing, from an evolutionary standpoint, are those concerned with direction. As we determine direction in everyday sounds, it…
The core of any camera is the sensor, and along with the lens, they define and constrain the performance of the camera more so than the downstream processing.
There have been many advances in sensors, with the move from vacuum tube devices to semiconductors being one of the great leaps.…
The World Teleport Association (WTA) has released Teleport Opportunities 2018, a new research report surveying teleport executives on market opportunities and obstacles to growth, investment, hiring and technology plans.
Since the beginning of broadcasting, announcers and narrators have spoken closely to microphones to boost the gravitas in their voices. They use proximity effect to sound richer, fuller and more intimate than they might naturally sound. But when they get too close, the result can be plosives. Here’s how t…
It is very tempting to take a laptop computer on location for live recording. It can work fine — until it doesn’t. Laptops, by their very nature, are more fragile and prone to failure than other recording devices. Be careful that you’re not the victim.
No memory card manufacturer has ever gotten a complaint about a card being too fast. Today, video cameras continually feature higher resolution and less compression, resulting in the need for cards of greater speed and capacity. It is a game that is constantly changing.
In this age of environmental consciousness, many companies often claim to be “eco-friendly” and concerned about the future of our planet, but it winds up being marketing slogan and little more.
As cameras have gotten smaller, so have the support accessories that allow them to be used creatively in production shoots. One interesting area is tabletop tripods, which are very light in weight but can often support fairly robust cameras.
