16.1.2 Classification of Multimedia Authoring Systems
16.1.2.1 Dedicated Authoring Systems: Dedicated Authoring Systems operate on single streams and are most widely used by single non-professional users with little or no knowledge about multimedia composition management. Such systems can be installed on desktop PCs. The video streams and images used here are generally captured by local cameras. Hence, these systems are not widely preferred for sophisticated applications.
16.1.2.2 Timeline-Based Authoring Systems: In this authoring system, multiple multimedia objects can be handled and position in timeline for each of these media can be specified. Earlier, only the sequence of these objects was given and editing or copying portions of timeline …show more content…
Many video tracks, their associated audio clips and separate audio tracks constitute these systems. Each constituent media in the presentation is given timing conditions. Such systems must provide facilities not only to view the entire set of objects at a single shot but also to focus on a single object by zooming in. If the system is authored well, then the object hierarchy will be clear and one can locate an object based on relative hierarchy. Deleting a parent object will result in removal of its subsequent sub-objects.
16.1.2.4 Programmable Authoring Systems: Such systems prove effective in the field of image analysis and processing with the help of specific subroutines for each task. User programmability is built into the system to facilitate analysis and evaluate the results as …show more content…
This progress is termed ‘navigation’ which can be performed in various modes. The widely preferred mode is direct approach where in user must know the result of successive navigation and how to proceed further. Free-form mode enables the user to determine the next sequence of actions. Browse mode is another mode in which the user, usually not much experienced seeks information about some topic. Search option to identify an object residing in an unknown location is a good example of browse mode. Navigation can be accomplished using a set of nodes and links. A set of operations may be performed on an object. From a node, a set of user actions branch out. For example, entering keywords to search for an object can be considered a node. Likewise, saving the results of the search can be taken as another node. Link is the sequence by which one can proceed from one node to the other. The process of identifying an object from an unknown location by searching for it using some keyword progresses in a step-by-step manner. This progress may be considered a link.
