Review: JVC GY-HC900 Camera
|
 |
JVC has a long history of developing relatively low price-point equipment, dating right back to its success in the 1970s with the VHS tape format. JVC products sometimes impact the broadcast mainstream but generally find greatest success in niche market segments such as news production where price and portability take priority over the no-comprise quality and robustness demanded by the leading studio-based and OB content producers. |

Fast-moving productions need multi-cam RF reliability
|
 |
Wireless acquisition creates a level of freedom not possible with any other form of filming yet only a decade ago the technique was barely possible. The technology enabling live real-time connections over radio frequencies has advanced leaps and bounds such that there is barely an entertainment, documentary, sports or news format today that doesn’t benefit from at least one link system. That means the demands on the kit continues to rise and includes the need for fail safe multi-camera operation, ease of use and backwards compatibility all within a small, lightweight and budget-friendly package. |

What is Next for Broadcast
|
 |
The Broadcast industry is always chasing new technology. Some of that technology is further than it appears to be, and some of it is closer to adoption than it seems. In part, early adopted technology is accelerated because of customer or business demands, and in the case of IP based environments, the driving factors are speed, cost reduction, and flexibility of workflow. To counterbalance these efficiency-based factors is a desire by content creators and customers to see more 4K HDR content on their new big screens. In some ways the push to deliver 4K workflows also makes the need to manage cost/performance even more urgent. |

Navigating Unfamiliar Territory
|
 |
The traditional broadcast model - where TV networks play content on a linear schedule, and viewers tune in on their TV sets - is under siege. Linear TV is not going away anytime soon, but the model is becoming less and less relevant. Thanks to the rise of OTT services, viewers have become accustomed to watching content when and where they want, on just about any device with an internet connection. For that reason, broadcasters must add an OTT component to their offerings. |

3D for Cinema, ProAV and Events
|
 |
Over more than a century of motion picture presentations there have been periods when 3D has emerged, and each time interest has faded away. The latest 3D wave goes back to the advent of digital technology for cinemas. Digital Cinema Initiatives (DCI) was formed in 2002 and delivered its first DCI Specification in 2005, when Doremi was well ahead with the necessary technology for a DCI-compliant player. It was very soon clear that digital cinema technology could sweep aside many of the shortcomings of the film-based 3D presentations, and so open the door to a new 3D era. The digital medium is far more accurate than film could ever be. With no film weave, sparkles, scratches, frame hops or wear, digital cinema delivers, steady, clean, sharp, in-sync presentations that are as good on the 200th run as the first. This is the perfect medium to provide a comfortable and exciting viewing experience for stereoscopic 3D movies. |

An effective strategy for monitoring broadcast audio loudness levels
|
|
One of the factors affecting a television viewers satisfaction and overall quality of experience is the consistency of the audio level of the programming. Inconsistent loudness levels between channels or between programming and advertisements can ruin a viewers television watching experience. Over the past several years, erratic audio levels have become such a source of contention among television viewers worldwide that countries have created guidelines and standards designed to minimize audio-level discrepancies. |

Testing mixed signals
|
|
It is fitting that a lot of the avid readers of this article are broadcast manufacturers flying over the Atlantic to NAB in Las Vegas so I have a captive audience to influence with an open invitation to come and visit us in the North Hall N5015. Whereas the new product range has been designed for applications in traditional settings such as engineering bays, OBs and Studios, some of the unique attributes of the PHABRIX Rx range on show at NAB are very much targeted toward broadcast manufacturers. Hence the appeal I hope to the passengers attempting to drink the flight dry once again. |

More than meets the eye

Synchronisation is not really a problem using two professional cameras. You just loop through your reference (black) to each and you are all done. In the old days, (well not that long ago), you had to worry about PAL SCH and accurate sync matching |
