Digital

Digital © Benoît Labourdette.

What is “digital”? Etymologically (17th Century), it is what has to do with numbers and their calculation. But since the advent of computers in the 1960s, “digital” refers to signals (text, image, sound, multimedia, etc.) transformed into numbers so that they can be processed by computers.

The digital is opposed to analog; for example, a vinyl record (analog) preserves the sound by burning a groove whose curve is analogous to the vibrations in the air, whereas in digital (CD, file, streaming), the sound is preserved in the form of a series of numbers representing, in a simplified way, this same curve of the vibrations of the air.

In summary, analog is a trace of the real (example: the negative in silver photography), whereas digital is a digital coding of this trace.

Until now, computers have used the binary code: numbers are represented as 0 and 1 only (the “bit”, the elementary unit of digital information). It is a very poor information (binary...), that’s why the bits are organized by groups of 8 (“the byte”). These 8 bits allow 256 possible combinations of 0 and 1, so one byte can store a number between 0 and 255, which can, for example, represent a letter of the alphabet, thanks to an international standard called the ASCII code. It is thanks to this type of common standard that computers can communicate with each other.

For example, each character in the text you are reading corresponds to a byte, which itself is a group of 8 bits. Bits can be stored in a thousand ways: black or white squares (the QR codes), magnetic magnetization (hard disks), light or dark (optical fibres), sound or silence (magnetic tapes and old modems), microcassette or flat (CDs, DVDs and Blu-ray discs) . The digital code can change media without losing information, unlike analog, which is dependent on its medium (you can’t put a vinyl disc in a cassette player for example).

We extend the term “digital” to all its uses: “digital video”, “digital cultures”, “digital economy”, “digital rights”, etc.


Poem in automatic writing about « Digital »
I intervened several times at ARTE, for INA Expert, for in-house training, for officials from various sectors of production. Concerns about SEO, discoverability, digital archiving, and the long-term preservation of online video productions are absolutely fundamental in a cultural and heritage-driven approach. Faced with the deployment of generative AI, some researchers proclaim conscientious objection. I believe there are mainly degrees and, more importantly, contexts of use. This experience, which we propose to report on, invites us to consider the place that can be given to the tools and uses of digital technology in the exercise of cultural democracy, and the role that social and cultural players can play through the mechanisms they create with people: what modes of cooperation are induced? Thus, the trainees can, for some, live in this day an awareness and discoveries that can radically change their professional practice. Third thread: the place of the spectator On Wednesday 6 May at 11.45 am, I am taking part in the round table « Audiences: how is digital technology reshaping the relationship to the performing arts? Play basketball... Here is its 1975 version: Every two years, at equivalent cost price, the capacity of computer tools doubles (mainly the power of microprocessors).
