I have some comments or questions to the definition of "multimedia" in your mail "Message-Id: <199308161443.AA05821@dkuug.dk>": > Multimedia: An adjective that can be applied to the creation, storage, > revision, compression, transmission, or presentation of information > with the following characteristics: > - it is digitally encoded > - its presentation involves at least two "types" of information > (text, graphics, raster image, animated graphics, moving image, audio) > - its presentation is computer controlled > - its presentation involves a dependence on time, either between two or > more pieces of content (e.g., before, after, during) or within a > time dependent piece of content (audio, video, animated graphics) > > All of these characteristic must be present to justify the use of the > term "multimedia" 1) In the NP of the MHMF project, it was said A fundamental aspect of the work will be to develop an agreed definition of multimedia and hypermedia. For the purposes of this New Work Item Proposal, the following definitions apply: Multimedia - "a structure mixing various types of content - like text, graphics, digitized speech, audio recording, picture, animation, film clips ..." If you explain what is wrong in the NP definition and how we can go well with your definition in the MHMF project, the purpose of your contribution will become clear and other contributions will be expected. 2) The sentence All of these characteristic must be present to justify the use of the term "multimedia" seems to too exclusive for the MHMF project for the reasons below: a) Some of information need not be digitally encoded. Computer controlled mixing of analog information is an important area and it should not be excluded from the MH model (maybe excluded from the MH framework of JTC1 activities). b) Computer controlled presentation is not always necessary. Computer controlled creation of information which is presented manually e.g. on VTR player should be included in the MH model. c) A structure mixing various types of *static* or *non-temporal* content is a start point of "multimedia" and it should be included at least in the MH model and it needs further discussiion whether the *static multimedia processing* is not a future concern of JTC1's activity or not.
