Testing Hybrid Workflows
|
 |
With the industry’s steady migration from traditional HD-SDI to IP and/or 12G-SDI infrastructures, broadcasters are now faced with the significant challenge of having to manage and monitor a wide array of new signal types in order to provide properly managed workflows. The switch away from HD-SDI is not happening overnight and, indeed, is happening at different speeds in different parts of the world. Due to this rapidly evolving technology landscape, reliable and versatile test and measurement (T&M) solutions have never been more important. |

Class: Pragmatism In Engineering
|
 |
A couple of years ago, Hermann Popp from ARRI came to me and talked about putting MXF in ST 2110. My initial take away was that his proposal felt like exactly the right way to solve the problem he presented, but was completely counter-intuitive to the IP Engineering purists who would push back on the concept of double wrapping the content. |

Making the Workflow Flow
|
|
The toughest things about being the Standards Vice President (SVP) is that everyone expects standards to be the most important thing. In all the systems that I’ve designed and deployed over the years, I've yet to find any production workflow that is 100% standards based. True, the core technologies may well be standards based, but the overall workflow is made up of many technology pieces from open source code, through de-facto delivery specifications based upon SMPTE or Trade Association Specifications that in turn depend on full, International Standards to work. I can already hear some folks saying "In the good old days, everything used standards", but I beg to disagree. |

State of the Nation: Wings, Fine Coffee and Fake Nudes
|
 |
One of the many attractions of this time of year is that I get to meet with my fellow judges for the IBC Innovation Awards, and see what the industry sees as the most important, most forward-looking projects of the day. For me, this says what the key talking points are going to be in September, far more eloquently than the endless press releases from vendors which are already tumbling into my inbox. |

IMF Adoption
|
 |
The Interoperable Master Format isn’t new. It’s been around for more than six years. Despite this longevity, the broad adoption since the publication of SMPTE 2067 has been pretty slow. This is perhaps more because of the age old mantra “if it ain’t broke don’t fix it,” than the ease with which many could interpret the standard. However, it is safe to say that movie producers blazed a trail in using IMF for original content delivery. Perhaps the key is that those early adopters didn’t have any significant tape based infrastructure that had been modified for file-based working when receiving content. So, many longer established content distributors have the immense resources to create the vast array of versions required to address the ‘version issue.’ This being how do you get the same content to look good on the back of an aeroplane seat headrest or an iPhone in the back of car as well as a good old TV set. Over time these resources have been diminishing and many organisations recognise that they have to adopt workflow automation to survive. |

NAB Intelligence
|
|
It's that time of year again. 06:30 on road bikes on the Las Vegas Strip with a merry bunch of folks who believe they look good in lycra. As we pedal West up the hill towards Red Rock there will be stories of the year just gone and questions about what to look for at the show. I, for one, will be attending the Devoncroft event to check up on who is spending what and where. I will then look forward to the topics that might be buzzing around the halls. I predict there will be many displays of Machine Learning hiding under the banner of Artificial Intelligence. Some of these will show better picture quality, others will show personalisation engines, some will be improved search tools and yet more will be synthesising pictures and motions to replace reality with and Artificial reality that's more compelling for the viewer. |

An Obituary to Timecode
|
|
A stoic and persistent character that stubbornly refused to change with the times, Timecode has finally passed on, but no-one has noticed. A long-lasting industry veteran, Timecode was brought into this world at an uncertain date in the late 1960s due to the needs of analogue tape workflows and the demand for synchronisation between audio and video devices. A joint activity between SMPTE and the EBU led to the work on Time and Control codes starting its journey to standardisation in the early 1970s. |

Moving to an IP Platform Considerations
|
 |
Audio transport methods have remained virtually unchanged in the broadcast industry for more than half a century. Common approaches to routing audio around large broadcast facilities have closely followed methodology employed in telco central offices, with the use of X-Y crossbar or crosspoint switching. |

Peace of mind in a complicated world
|
 |
For many in the broadcast industry these are challenging times. With competition coming from all angles and different technological camps advocating different approaches to infrastructure and the way forwards. With the number of different variables increasing, the choices of whether to use SDI or IP infrastructures, and the choices around HDR and WCG let alone the on-going distraction of UHD / 4K. |

Dick puts it all together
|
 |
Many of you will be reading this as you prepare for IBC. Some may even be reading it on the train/plane/ship to Amsterdam. I want to take a couple of minutes of your time to look at a last minute addition to IBC. It concerns IP, but trust me: this is good news so please do not stop reading just yet. |

Realising the ideal
|
|
On 26 July 1916 there was a public meeting in New York. It was called by a group led by Charles Francis Jenkins (and more on him in a moment). But the guest speaker was Henry D Hubbard, at the time the secretary of the US National Bureau of Standards. This is some of what he said:

Taking aim
|
|
We have a lot to look forward to this year. In Europe we are likely to find huge amusement in the American presidential election which this year seems to be throwing up an unprecedented set of clowns. In midsummer we have the Olympics in Rio, which should be quite a carnival. |

Here is the news
|
 |
In mid-May the EBU and SMPTE brought together many of the great and the good of the television industry and me to a forum on emerging media technologies. Held in Geneva, in a hotel expensive even by Swiss standards, it was supposed to set the agenda for the future, to share solutions so the future will be bright. |
