COMMUNICATION DEVICE, COMMUNICATION SYSTEM, METHOD OF USING COMMUNICATION DEVICE, AND PROGRAM

摘要

A communication device is used at a one hub to share information by transmitting and receiving image data and sound data among a plurality of hubs via a communication network. The communication device includes: a transmitting unit that converts at least one selected from a group consisting of image data and sound data from the one hub and image data and sound data transmitted from a different hub other than the one hub, into a digital signal that conforms to a predetermined standard so as to transmit the digital signal to a receiving device that supports the predetermined standard. The transmitting unit transmits the digital signal to the receiving device when the receiving device is a dedicated receiving device that is previously specified and that has an image recording/sound recording function or when the receiving device is a receiving device that does not have an image recording/sound recording function.
