SDI has been and continues to be a mature and stable standard for the distribution of video, audio and metadata in broadcast facilities. From its inception in the 1989 to the modern quad-link 12G-SDI available today, it has stood the test of time and even with the advent of IP and Ethernet, it shows no sign of waning.
As cloud and cloud words become common in the media lexicon so has the term blockchain. Let’s take a closer look at blockchain. Not all technologies work everywhere or should they! Each time one industry sector introduces a new concept or technology, all the other market sectors latch on and claim they do it too. IoT allows you to speak to the shower and tell it what temperature you like and wake up your house before you get home. That doesn’t mean it works in professional media!
The 2nd generation of local broadcast TV professionals is retiring. Who will replace them and where will they lead local TV?
Following the myriad of transitions in media production and distribution, is a combination of new technologies that create media and ones that support the consumption of media.

Here we look at one of the first practical error-correcting codes to find wide usage. Richard Hamming worked with early computers and became frustrated when errors made them crash. The rest is history.
Within broadcast there has always been a quest for higher and higher resolution with improvements in wider color fidelity. The quest has always been to deliver what we see to the audience, often this is limited by technology or cost of production, but today there is the possibility to increase the resolution to 4K/UHD with High Dynamic Range (HDR) and Wide Color Gamut (WCG) that can convey that window on the world to the consumer.
So many buzzwords & acronyms and so little time! I thought this was a better title than Understanding the Differences Part 2.
While I am not one to wax nostalgic, the last decade was a pretty exciting one in media technology. HD-SDI came into its own in the early aught (00) years, mobile and wireless media, OTT and streaming all became mainstream. IP and file based media production was introduced and standardized (SMPTE ST2110) however, let’s not forget 3G, 12G, 4K, 8K, UHD and HDR. Whew! Plus VR & AR, eSports and 3D (oops) and the world got cloudy.
