There are many different requirements and expectations in the field of computer security and it may be as well to set out what some of them are. Computation is everywhere, from the ubiquitous iPhone to the military computer in an underground installation, and it is unrealistic to think that one security approach would suit all requirements. Computer security is also awash with buzzwords and these will crop up here with definitions of what they might mean.
With the recent advances in artificial intelligence, post-production rotoscope tools are now so good that some DOPs are asking if we still need to use green screen at all, or at least, in quite the same way. Suddenly, it seems any background, no matter how complex, can be replaced in seconds on the editor’s timeline, allowing DOPs to shoot complex compositing assignments faster and more economically. For broadcasters, the benefits of an AI-powered rotoscoping tool are substantial as producers can repurpose a treasure trove of existing footage packed away in libraries and potentially reduce the need for new production or costly reshoots.
Television production these days is tricky enough without adding virtual elements like augmented reality (AR) graphics, but that’s exactly what Taipei-based production company Getop did for the live telecast of the 2020 Golden Melody Awards (GMA). The highly rated annual televised awards ceremony - considered the “Asian Grammys” by many - celebrates top musical talent from across southeast Asia.
IP networks provide us with untold flexibility, but this flexibility presents us with interesting challenges of control. Developments in SDN (software defined networks) are leading the way through the separation of the control and data plane. And as we discover more of what SDN means, we soon realize that broadcasters are closer than they may think in achieving its operation.
When CBS Sports broadcasts images of the players taking the field on February 7th for Super Bowl LV to millions of viewers around the world, it will be the culmination of the most challenging season for live football sports production in the U.S.
The requirement for a wide dynamic range to be provided economically is usually met by what is loosely called gamma, which is a non-linear transfer function having numerous drawbacks. However, there is an alternative form of what might loosely be called gamma, which is floating point.
In modern consumer electronics history, every new year begins with an early January Consumer Electronics Show, followed by the April NAB Show, both in Las Vegas. Significant new home and broadcast video and audio technologies are often rolled out at both shows, targeted for near-opposite markets wanting to enjoy or produce lots of TV. With no physical exhibits since CES 2020, manufacturers are struggling to impress virtual visitors and reporters with better and larger images with what they can see on their local computer screens.
Timing accuracy has been a fundamental component of broadcast infrastructures for as long as we’ve transmitted television pictures and sound. The time invariant nature of frame sampling still requires us to provide timing references with sub microsecond accuracy.
