Specification and Implementation of an Extensible Multimedia.. - Hauser, Rothermel (2000) (Correct)
....of multimedia documents using standard concepts for the specification of the temporal and spatial layout of documents. These concepts are well understood and base of several different multimedia authoring tools. For example, temporal interval operators are used Madeus [8] and TIEMPO [16]. Also these approaches use different concepts to define the spatial layout, for example absolute positioning. Multimedia systems provide one concept for the temporal layout, one concept for the spatial layout and sometimes a further concept for interaction. The second area of support is for the ....
....several publications on research concerning the description of concepts. Main topic of interest is the temporal specification of multimedia documents. In [12] different concepts for the temporal specification were described. Some of them can be represented by operators for the usage in MAVA. In [16] a system basing on ten temporal interval relations and relations for interaction is presented. Compared to the research work done in this area MAVA does not define new temporal or interaction concepts. MAVA wants to integrate existing concepts. Figure 3 A MAVA document. image (map) audio ....

A Component-based Extensible Multimedia System - Hauser (2001) (Correct)
....have to know these systems in detail for content creation and support of users of these systems. Examples for such an approach are Macromedia Authorware or Question Mark Designer. Also all approaches that provide a fixed language belong to this category (e.g. SMIL 1.0 [3] SMIL 2. 0 [10] TIEMPO [1] or Madeus [2] Their use is limited to the application area defined by their language concepts. For example it is impossible to specify a multiple choice question in SMIL 2.0 that gives the user a certain amount of time and the user can alter his answer within the time period. The reason is that ....
....(e.g. an interval manager, a CBT manager or an ITV manager) A manager is programmed in the programming language of the MAVA system (i.e. Java) A manager analyzes the usage of operators that belong to its responsibility. For example, a manager that realizes temporal interval operators [1] analyses the used interval operators and creates an internal representation (i.e. a scheduling graph) based on this scheduling graph the manager controls the presentation of media item (e.g. telling them when to start or stop their presentation) The semantics of operators is specified more ....

....base managers for the development of new managers. This will be shown by an example of a manager and a suitable base manager for a temporal concept. A scheduling graph is a suitable internal representation for a temporal base manager. A detailed discussion about scheduling graphs can be found in [14]. At first a temporal manager will create a scheduling graph according to the operators used in a document. During presentation the temporal base manager uses the scheduling graph to determine when to send control events (e.g. start stop presentation) to media items. A base manager acts on an ....

Multimedia Authoring with MAVA - Hauser (2000) (Correct)
....of particular documents. Multimedia systems provide fixed concepts for the specification of temporal and spatial layout of documents. This means that an author has to use these concepts. Additionally, most multimedia system provide a concept for the specification of interaction, e.g. TIEMPO [12], but sometimes a scripting language has to be used to describe the interaction semantics [3] Hence, knowledge of computer programming principles is required from authors. 2.1 Discussion of the Scenario For the realization of the example given in the introduction the evaluation of existing ....
....parts are grouped and replaced by a container node. Containers also allow the storage of parts of the document as templates for later reuse. Compared with existing approaches it can be stated that MAVA uses the operator approach as meta document model. Existing approaches, like TIEMPO [12], Madeus [7] or SMIL [4] use also concepts respectively relations that can be represented by operators. In contrast to the MAVA approach these approaches provide a fixed set of operators. If a document cannot be described with these operators there is no way to realize the document with these ....

A Cross Media Adaptation Strategy for Multimedia Presentations - Boll, Klas, Wandel (1999) (11 citations) (Correct)
....cross media adaptation which means that media elements and also entire fragments of a multimedia presentation can be replaced by different media elements fragments which can be of different media type. We find the following related approaches that address some aspects of cross media adaptation. [17] proposes a cross media adaptation technique focusing on the scheduling of alternatives aiming at best effort assignment of currently available resources. The approach presented in [11] proposes cross media adaptation of Web pages to client resources in the Internet before the actual delivery to ....
....presentation alternatives. The Z Y X [1] model uses a similar switch operator to model alternatives and complex media elements encapsulate substructures of Z Y X documents. CMIF [4] allows nested presentations and offers channels that can be used to model alternative presentation parts. TIEMPO [17] is another example of a document model that supports the modeling of presentation alternatives by means of selection groups that can be nested. Obviously, the cross media adaptation strategy we propose can be applied in the context of all these models. We have applied the model exemplarily in ....
