Abstract: The invention includes structures and schema for organizing and inter-relating objects, data, or files, including relational, network, hierarchical, and entity-relationship models, among others, that are dynamic, that is changing with time. This includes manipulating structures by conversion, compression, compaction, and compilation, for various purposes. Also included is generating structures for storing, organizing, and managing dynamic objects for retrieval and presentation. A discussion group for collaborative participants is also provided. A time-based dynamic object within a plurality of stored dynamic objects is stored. Each dynamic objects comprises a plurality of predefined attribute fields. Requested dynamic objects are assembled in real time so that the requested dynamic objects are displayed on the basis of the start-time attribute field of each requested dynamic object.

Abstract: An apparatus for transporting digital multimedia receives signals for a plurality of single program transport streams (SPTS). Each SPTS is transmitted as a series of groups of a predefined number of transport stream packets. An input buffer that receives the packets is configured to hold only the predefined number of packets at any point in time. A table builder receives packets from the input buffer and assigns a set of unique packet identifiers to the packets from each SPTS, reconfigures each program map table in the packets, and generates a program association table for a multiple program transport stream (MPTS). The table builder retains unaltered the program clock reference in the data packets. A first-in, first-out buffer combines packets received from the table builder into a MPTS. An output stage modulates a carrier signal, such as for a television channel, with the MPTS.

Abstract: In some embodiments, the disclosed systems and methods provide a client-server infrastructure capable of supporting a variety of asynchronous and synchronous collaboration activities in a so-called collaboration place. Some of these activities include chatting, viewing and/or editing one or more data files, and sharing one or more applications, data files, and/or displays. The client-server infrastructure supports seamless navigation between the supported asynchronous and synchronous activities in the collaboration place. Additionally, the client-server architecture supports data persistence, so that data files associated with the collaboration place can be stored for subsequent access.
