The history of communication technologies (media and appropriate inscription tools) have evolved in tandem with shifts in political and economic systems, and by extension, systems of power. Communication can range from very subtle processes of exchange to full conversations and mass communication.
The communications efficiency of the Morse Code preceded that of the Huffman code in digital communications by over 100 years, but Morse and Vail developed the code purely empirically, with shorter codes for more frequent letters. The submarine cable across the English Channel, wire coated in gutta percha, was laid in 1851. [14]
The term "video," if not used exclusively to describe motion photography, is ambiguous in multimedia terminology. Video is often used to describe the file format, delivery format, or presentation format instead of "footage," which is used to distinguish motion photography from "animation" of rendered motion imagery. Multiple forms of ...
The history of film technology traces the development of techniques for the recording, construction and presentation of motion pictures. When the film medium came about in the 19th century, there already was a centuries old tradition of screening moving images through shadow play and the magic lantern that were very popular with audiences in ...
The history of electrical signal processing is closely tied to the development of electronic communications technology, beginning in the mid-18th century with the invention of the capacitor, which allowed for the capture and storage of electrical charges.
The history of motion graphics is closely related to the history of computer graphics, as the new developments of computer-generated graphics led to wider use of motion design not based on optical film animation. The term motion graphics originated with digital video editing in computing, perhaps to keep pace with newer technology. Graphics for ...
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and ...
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
