....quality of service is to be expected, namely a frame rate and a resolution in the case of video. This requires resource reservation and runtime support like scheduling. In the AMOS project at GMD IPSI in Darmstadt, Germany, an object oriented database system has been enhanced to support realtime [8]. However, while internal processes have been optimized to a large extent, no guarantees can be given. Therefore a media server with data independence and realtime playout functions based on the planning and scheduling of processing times and buffer sizes is still not at hand. The goal of the ....

.... Routines (UDR) This mechanism is also extensively used to enhance those systems with media data types (for some examples see [5] 6] While the vast majority of these media extensions do not provide physical data independence, two exceptions from this rule should be pointed out: 1) In [4] a continuous media DataBlade providing device independence, location transparency, and presentation independence is described, and (2) 17] presents a DB2 Extender for images providing format independence where materialization is controlled through cost based optimization. 3 Transformation ....

....media. The main concepts of the CLF DataBlade are a generic data type, called CLF, a client buffer mechanism enabling continuous presentation with respect to VCR interactions [12] and a buffer triggered adaptation method to dynamically adapt to short term bottlenecks at high system load [8]. This extension provides the basic functionality needed for interaction with MM data. Browsing, however, requires more structured interaction possibilities, based on vague user queries. Hence, we added a retrieval engine to the basic architecture, enhanced the CLF buffer strategy, and provided ....
....continuous, jitter free video playback and enables VCR functionality and video switches both with low startup latency. For buffering, we segment videos into so called buffer units . Such single segments represent a logical unit of a video instance, e.g. a Group of Pictures of an MPEG stream [8], and are requested from the server by the buffer manager. To support interactive browsing applications, our buffer management algorithm preloades and replaces single objects based on an estimation of their relevance for the ongoing browsing session called buffer value assuming that a user ....

....the DBMS functionality extending the IDS, and a client buffering module that requests media parts for presentation. In the following, the basic concepts of the CLF DataBlade that have been integrated as multimedia database extensions are briefly outlined. For more detailed information, we refer to [23]. Continuous Long Field. We provide a datatype Continuous Long Field (CLF) as a generic representation for any kind of continuous media, such as audio, video, or animations. This datatype supports operations for editing and presentation, e.g. insert , request , or delete . Structural ....
