Technology / Home Audio / Digital Technology: Human beings directly process information in an analog format. That is, our senses directly convey information to the brain in the form of constantly varying amplitudes and frequencies that approximate the impact of outside stimuli upon the receptors (eyes and ears, etc.) Of the organs involved. Digital technology is a method of translating this same information in the form of packets (bytes and bits) of numerically equivalent values. This enables input transducers (microphones, cameras, chemical sensors, etc.) To produce differential waveforms that can be reduced, down to the smallest differences, to a number. This number is transmitted to a receiver with a digital to analog converter that allows the original analog information to be reconstructed for the benefit of our human brains. This is of course an egregiously simplified explanation of the most significant technology of the present time. We invite you to explore more this topic deeply, not just for audio/video, but to understand the new world we have entered.
Technology / Cell Phones / Digital: A method of encoding information using a binary code of 0s and 1s from electrical pulses. Because digital signals are made up only of binary streams, less information is needed to transmit a message. MORE
Technology / Television (TV) / Digital Video (DV): Any video format that relies on digital technology for recording and/or editing. For example, video recorded with a digital camera or edited on a nonlinear editing system. MORE
Technology / Television (TV) / Dolby Digital - AC-3 Compatible: Formerly known as Dolby AC-3, or audiocoding-3, delivers the movie experience through a maximum of 5.1 channels of surround sound audio. Since the mid-1990's, this Dolby sound format has become the mo MORE
