Abstract: A method and apparatus for a collaborative meeting room system. In response to user input, an electronic device starts a meeting timer to begin timing a meeting at which a previously-created meeting agenda is used. The electronic device causes a projection device to project a running meeting timer, as a result of starting the meeting timer. An agenda item included in the previously-created meeting agenda is retrieved, as a result of starting the meeting timer. The electronic device causes the projection device to project meeting minutes for the agenda item, as a result of retrieving the agenda item.

Abstract: Geographically distributed conference sites each have a telephone receiver and a dataconferencing appliance connected to a shared voice call network. Each site also has a display device for displaying images comprised of image data produced by an image source. The dataconferencing appliance is connected to a data network that links the sites independently of the voice call network. To initiate a dataconference session between the sites, a voice call session is first established between the telephone receivers via the voice call network. An address negotiation procedure implemented in software or hardware of the dataconferencing appliance is then manually initiated to identify a network access code and communicate it to at least a second one of the sites within the voice call session. The network access code is used to establish a data communication session via the data network for convenient transmission of image data between the sites.

Abstract: A method of decompressing a set of subsampled image data is disclosed. The method includes reading a first subset of the subsampled image data into a cache memory and into a buffer, wherein the buffer has an amount of memory equal to or less than the cache memory, calculating chrominance values for at least some pixels of the subset of the subsampled image data to form decompressed image data, and outputting the decompressed image data.

Abstract: A method of transmitting data between multiple nodes of a network system is provided. The method may include a packaging an initial bundle of data into a plurality of initial data packets and packaging supplemental data into a plurality of supplemental data packets. The method may further include transmitting the initial data packets using a first protocol and transmitting the supplemental data packets using a second protocol.
