Abstract: Computer-implemented methods of and systems for providing a viewing experience to a user are disclosed. In one such method, an electronic document is provided. The electronic document has read-only content and embedded executable code which executes upon opening the document. The executable code influences a viewing experience. A remote database having data about a user is provided and data is received from the database for use in conjunction with the embedded executable code in order to provide a viewing experience to the user.

Abstract: Methods and systems in accordance with the present invention manage bandwidth use in broadcast communications. More particularly, methods and systems in accordance with the present invention may be used to achieve reliable broadcast communications in a wireless network. They may provide network communication software that controls when data packets are transmitted via a wireless physical layer interconnect, thus increasing the overall reliability and throughput that are achieved when using broadcast communications. Methods and systems in accordance with the present invention improve throughput in various types of networks, e.g., Ethernet networks in which the network switches have a limited broadcast capacity, including wired networks.

Abstract: Methods and systems in accordance with the present invention provide a peer-to-peer replicated hierarchical data store that allows the synchronization of the contents of multiple data stores on a computer network without the use of a master data store. The synchronization of a replicated data store stored on multiple locations is provided even when there is constantly evolving set of communications partitions in the network. Each computer in the network may have its own representation of the replicated data store and may make changes to the data store independently without consulting a master authoritative date store or requiring a consensus among other computers with representations of the data store. Changes to the data store may be communicated to the other computers by broadcasting messages in a specified protocol to the computers having a representation of the replicated data store.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide a system and method for sharing and recording information on a wired or wireless computer network during synchronous and asynchronous sessions. A software program uses computers to enhance the collaboration, teaching, learning, presentation, and sharing of information and to record multi-media events for later playback and interaction with these events. Collaboration is enhanced by using features that allow broadcasting presentations, sharing, editing and replying to documents, taking notes, viewing participant information, creating and responding to polling questions, asking and answering questions and providing feedback on the pace and difficulty of the session.

In particular, users may add notes during the recording of a multi-media presentation that are synchronized timewise with the presentation. When the presentation is played back, the notes are displayed at the correct time and space in which they were added.
