The current social and medical situation with lockdowns and distancing is unleashing new ideas at local TV stations. Some will become the new normal.
OTT delivery continues to expand to meet the relentless growing consumer demand. This trend shows no chance of abating and technologists are continually looking to innovation to scale infrastructures accordingly. In this sponsors perspective, Ryan Nicometo, SVP of Product for Vecima, presents the OTT Scale – Maturity Quadrant to help decision makers clearly see the potential technical challenges and opportunities to meet the demands of OTT delivery.
The first set of quarterly financial results during the lockdown has given the clearest indication yet of what impact the crisis is having on sectors and individual companies in the video services and broadcasting sector, with a stark divide between winners and losers, but with all players affected in some way.
It’s all very well reading all this theory about colorimetry, but what can be done in practice? First of all, it is necessary to consider that imaging, be it still or moving, is a creative process that relies totally on technology. Wherever that happens, there are always two different ways of thinking about choices: objective and subjective.
KMSS lights up a new liquid-cooled transmitter system with just 30 days to TV’s most-watched event.
20 years ago, broadcast television went through an evolution as it transitioned from analog to digital distribution. This migration was driven by the demand for larger channel counts and spectrum reallocation. Since that transition, another, even more significant sea change has occurred, the internet.
Whether we’re routing signals or remotely operating equipment, the need for reliable system control is one of the most important aspects of a broadcast facility. But as we migrate to IP, some of the working practices we took for granted with SDI operation don’t necessarily transfer and this is most evident in signal routing.
The CRC (cyclic redundancy check) was primarily an error detector, but it did allow some early error correction systems to be implemented.
There are many different CRCs but they all work in much the same way, which is that the data to be protected are divided by the CRC polynomial. This was done serially by shifting the data bits into the CRC generator at the same time as they were being written to a medium such as disk or tape or sent into a serial transmission line.
