Challenges for Copyright by ICT: Introduction

Traditional copyright and the practice of paying royalties to the creators of intellectual property have emerged with the introduction of the printing press (1456). Therefore early copyright law has been tailored to the technology of print and the (re) production of works in analogue form. Over the centuries legislation concerning the protection of intellectual property has been adapted several times in order to respond to the technological changes in the production and distribution of information.

Yet again new technologies have altered the way of how (copyrighted) works are produced, copied, made obtainable and distributed. The emergence of global electronic networks and the increased availability of digitalized intellectual property confront existing copyright with a variety of questions and challenges. Although the combination of several types of works within one larger work or on one data carrier, and the digital format (although this may be a recent development it has been the object of detailed legal scrutiny), as well as networking (telephone and cable networks have been in use for a long time, although they do not permit interactivity) are nothing really new, the circumstance that recent technologies allow the presentation and storage of text, sound and visual information in digital form indeed is a novel fact. Like that the entire information can be generated, altered and used by and on one and the same device, irrespective of whether it is provided online or offline.

Bandwidth

The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems.

Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all.

In digital systems, bandwidth is data speed in bits per second (bps).
