Abstract: Environments with unreliable delivery may result in faltering presentation of multimedia objects, due to missing time stamp deadlines. This may be alleviated by introducing more flexible time stamping. To avoid this, additional MPEG-4 object time information is sent to the client. This requires a new dedicated descriptor, carried in the Elementary Stream Descriptor. The new more flexible timing information will have two features. First, instead of fixed start and end times, the duration of an object can be given a range. And second, the start and end times are made relative to other multimedia object start and end times. This information can then be used by the client to adapt the timing of the ongoing presentation to the environment, while having more room to stay within the presentation author's intent and expectations.

Abstract: A computer-implemented method of drawing a multimedia story including at least one episode is provided which represents a plurality of multimedia fries (e.g., text, sound, video, and picture files) graphically in a "time-box" which can be connected to other time boxes to for a time box diagram. A user can easily stretch or shrink, reposition, delete, or otherwise manipulate the fries graphically using the time boxes in order to produce a final multimedia story within given temporal (time) constraints. The method according to the invention includes steps of inputting to a processor story data having at least one episode, and, for each episode, generating first and second events and temporal constraints.

Abstract: A method of automatically aligning a written transcript with speech in video and audio clips. The disclosed technique involves as a basic component an automatic speech recognizer. The automatic speech recognizer decodes speech (recorded on a tape) and produces a file with a decoded text. This decoded text is then matched with the original written transcript via identification of similar words or clusters of words. The results of this matching is an alignment of the speech with the original transcript. The method can be used (a) to create indexing of video clips, (b) for "teleprompting" (i.e. showing the next portion of text when someone is reading from a television screen), or (c) to enhance editing of a text that was dictated to a stenographer or recorded on a tape for its subsequent textual reproduction by a typist.

Abstract: A floor planning technique is provided herein wherein an initial floor plan having a predefined area and a number of overlapping modules is used to produce a final floor plan having the same predefined area and no overlapping modules. In order to eliminate the overlaps, a two stage process is performed. The first stage includes minimizing the overlaps by performing a series of move and/or reshape operations on the overlapping modules. The amount an overlapping module is moved and/or reshaped is based upon a computed net repelling force. After the move and/or reshape operations no longer minimize overlaps, the second stage is performed. The second stage, referred to as fitting, fits each overlapping module into the predefined area by awarding the overlapping area to the module or protruding the overlapping module into available space surrounding the module. The space that a module extends into is determined by calculating attracting forces.

Abstract: At least two direct access storage devices (DASDs), which are predetermined to record the same data from a central processing unit (CPU), are normally kept synchronzied with each other except during the power up phase. The DASD synchronization is controlled and maintained by synchronization control means independent of any commands from the CPU. When one or more commands such as SEEK and SET SECTOR or LOCATE commands are transferred from the CPU to a control unit over a single data transfer path between them, desired identical records on the synchronized DASDs are concurrently located while the DASDs are disconnected from the data transfer path. Upon locating the desired identical records, the DASDs are reconnected to the data transfer path. Then, a WRITE command is transferred from the CPU to the control unit for concurrently recording the same data onto the synchronized DASDs at the desired record locations.
