Video: DOCSIS 3.1 – An In-depth Overview

Posted on 24th August 2018 by Russell Trafford-Jones

An in-depth talk explaining DOCSIS 3.1 from SCTE by Cisco’s Ron Hranac. DOCSIS 3.1 is the latest Data-Over-Cable Service Interface Specifications.

The presentation will include information on the following:
– Why DOCSIS 3.1?
– Basic principles of Orthogonal Frequency Division Multiplexing (OFDM).
– Spectrum allocation.
– FEC performance enhancements.
– New Proactive Network Maintenance (PNM) measurements.

CableLabs released version I01 of the new specification in late October 2013. DOCSIS 3.1 introduces a new physical layer, improved Forward Error Correction (FEC) and other features for high-speed data transmission on cable networks. Scalable to 10+ Gbps in the downstream and 1+ Gbps in the upstream, DOCSIS 3.1 supports services competitive with fibre to the home, but using cable’s HFC platform. Cisco’s Ron Hranac provides an overview of DOCSIS 3.1 from a physical layer perspective.

Video: The Fandom of the Opera

Posted on 23rd August 2018 by Russell Trafford-Jones

A lecture by Mark Schubin on how a 400-year-old art form helped create modern media technology.
Believe it or not, electronic home entertainment was invented for opera audiences. So were consumer headphones, movies, newscasts, and pay-cable. The first sportscasts were in opera houses.

The first wireless broadcast? The first commercial digital recording? The first live subtitles? All opera.

The idea of transmitting opera motion pictures and sounds live to theaters worldwide appeared in print in 1877, to homes in 1882. Without opera, there might not be communications satellites. And, according to pioneering radiologist Percy Brown, “No opera, no X-rays!” The first opera recordings were made 17 years before Edison’s first phonograph, and 76 years before that an automaton played opera music for Marie Antoinette. In the 21st century, labs around the world are working on ultra-high-speed communications systems for opera and have discussed neutrino communications and quantum entanglement. Galileo, Kepler, Lavoisier, Matisse – all had opera-technology connections. Stereo sound? The laryngoscope? Broadcast rights? All for opera. Really. Watch and be amazed.

Video: Making SMPTE ST 2110 installations work

Posted on 21st August 2018 by Russell Trafford-Jones

Philip Schofield, MD of Crystal Vision and Richard Lawrence the Principal Software Engineer, talk about implementing ST 2110 highlighting how to deal with some of the challenges of putting together a live media IP installation, including network security, firewalls, compatibility between equipment suppliers and new methods of monitoring and synchronisation.

In a SMPTE UK Section meeting held at Crystal Vision, this talk looks at the reasons not to move to IP and the reasons why it makes sense and demonstrates a small IP system, at work. And covers:
