- Read the feedback, notes from the last show
- Begin recording
- Introduction and description of the podcast, goals, modus operandi.
- What An investigation of everything from a British perspective by two brothers (who consider themselves to be relatively normal chaps), one topic at a time.
- Who Geoffrey Campos (engineer and devil’s advocate),
Benjamin de-Campos (designer and believer).
- How Choose a topic of interest, spend a little time researching it, have a discussion then publish the notes - which are available on the site to read along!
- Why The main benefits are the fostering of a greater understanding of the world before we die and hopefully, to prompt further thought and discussion from our listeners.
- The topic we will be discussing in this episode is Television
Something that's happening over there, displayed over here. Better yet, something that happened over there now displayed over here. Increasingly, something that never happened, displayed. There's nothing not to like about the concept of television. We're a highly visual species and the ability to see things that we have not witnessed (or are not witnessing) is a magic trick that in a just world, we should never get over. Ever since that great Scot, John Logie Baird managed to force his brain to accept the incredible abstraction that is the transmission of moving pictures, there has been nothing to slow the torrential adoption of the one eyed monster. We are now friends with Friends, tearful at the deaths of strangers, exhilarated at the feats of the brave and in thrall to the sway of advertisers. How great a part in our shared culture do the luminaries of television form? How fares their art? How might the wondrous technology itself change going forward?
What we’re not talking about
Each bullet is a talking point. Sub-bullets are topics that may or may not be covered. Usage: Read the bullet and sub-bullets then talk about some or all sub-bullets.
- He was a kind of failure but he is remembered as the inventor of television which is only half-true.
- Well the Brits were the first with ‘regular’ TV broadcasts to experimental mechanical televisors in the early 30s but it was indeed the Nazis that beat the Limeys with so-called ‘high-definition’ television in 1935
Gorballs fiddling with one of the new 'People's Radio Sets' at the Annual Radio Exhibition in 1938.
- ‘Oh, it’s going to give us incurable diarrhea’ and etc.
- Pre-War television, what kind of guff were (not many) people watching?
- Post-War television, the drug of the nation
- What about early television over the rest of the world?
- What’s the archival status of this guff?
- Mechanical television
- INGSOC telescreen, 1984
- CRT small, blurry, of a quality that millennials literal cannot see. Channels switched over instantly. A large set would weigh 12 metric tonnes - enough to crush a baby elephant.
- NTSC - 525 lines, 30fps
- PAL - 625 lines, 25fps

Colour RCA TVs From 1954.

- Wider colour gamut but, when the smaller ‘normal’ sRGB colour gamut is displayed on an AMOLED screen, everything looks over saturated.
- Seriously? Sitting through ads? In this day and age? Eff that and eff you.
- Fame, lets him loose, hard to swallow

Terminology specific to the topic

- AMOLED Active-Matrix Organic Light-Emitting Diode.
- CRT Cathode Ray Tube. Scanning electron beams on a massive, semi-evacuated glass tube that weighs tons.
- IPS In-Plane Switching
- LCD Liquid Crystal Display. Uses Nematic fluid crystals to block the light from LEDs (or other light sources) in order to switch off particular picture elements, determined by TFTs.
- LED Light Emitting Diode. The strip lights behind all LCD tellies.
- OLED organic light-emitting diode
- PAL/NTSC Phase Alternating Line - colour system in Europe, National Television System Committee - colour system for analogue tellies in the Americas.
- Pilot A rough (not so rough these days) episode created for television network executives to secure funding for a television series.
- Remote Control A radio frequency and later an infrared and later a Bluetooth labour saving control mechanism that makes it possible to switch the content without having to get off the sofa.
- Teletext Like the internet but occupying the spare frequencies of analogue broadcast signals. Booked some
- TFT Thin Film Transistor. The matrix of switches that control the matrix of pixels in a display
- Tubes/Valves Weird glass objects that do things that no one still living understands.
- Details about site, contacts, next show: Gambling
- Recording ends, postmortem recording begins
