Slow-Scan television (video transmission through analogue phone lines), 1987, 34.5 (W) x 42 (D) x 47 (H) cm [13.5 x 16.5 x 18.5 inches]

"Conversation" is a Slow-Scan TV work by Eduardo Kac realized at the Centro Cultural Três Rios, in São Paulo, on November 17, 1987.

Slow-Scan TV was an early type of videophone that allowed the transmission/reception of sequential still video images over regular phone lines.

It took from eight to twelve seconds to transmit each image.

Instead of considering each picture as a final form or the sequence of images as illusion of movement, Kac explored the live process of image formation.
