Providing a presentation on a network having a plurality of synchronized media types

A presentation system is disclosed for synchronizing a performance of a plurality of presentation content portions at a network node, wherein, e.g., when two such content portions are to be presented concurrently at the network node, at least one is delayed until the other such portion can be presented concurrently therewith. That is, these two portions may be received by the network node at times sufficiently far apart so that the earlier received content portion must have its presentation appropriately delayed in order to be presented concurrently with the second content portion. In one embodiment, the content portions are transmitted via at least a portion of the Internet to a plurality of network nodes, wherein the presentation system can distribute the presentation content data to the network nodes via a plurality of network routes and presentation formats. In particular, a first portion of the content data may be provided as slides in, e.g., HTML, while a second portion of the content data may be provided as an audio/video stream. Additionally, the present invention can provide various portions of the content data from a plurality of network server nodes, and during a performance of the presentation, the presentation receiving network nodes can determine a particular variation of the presentation to retrieve from the network server nodes. In particular, the retrieval of presentation data depends upon the transmission characteristics of the network such as data transmission rate. Thus, if a low transmission data rate is detected at a first network node, presentation elements of a reduced size can be retrieved. Alternatively, if a higher transmission rate is detected at a second network node, presentation elements of greater size (and corresponding enhanced quality of presentation) can be retrieved. Thus, within a single performance, network nodes with varying available network bandwidths can synchronously and simultaneously provide the presentation.

Communication apparatus, relay apparatus, communication system, communication method, and communication program

A communication apparatus has a plurality of interfaces serving a plurality of networks. The communication apparatus selects an interface according to electric wave reception intensity to reduce power consumption and contribute to the maintenance of reliability in communication. The communication apparatus (communication terminal apparatus, the other party's communication terminal apparatus) is used for communication in such a way that the communication apparatuses are connected to the plurality of networks wirelessly to carry out communication through each network. The communication apparatus has the plurality of interfaces (cellular interface CI, WLAN interface WI) responding to the networks. The communication apparatus also has controlling unit (power supply controlling unit) that connects any one of the interfaces to the power supply to actuate the connected interface, and that connects an interface on rest to the power supply in response to a communication state of an interface on communication to change communication connection from the interface on communication to the other interface on rest. The communication apparatus changes the interfaces while maintaining communication with the other party's communication apparatus.
