ABSTRACT:
When one of two IP telephones that are maintaining a call receives a TV camera connection request, the IP telephone obtains a URI of an IP TV camera service from a resource record of the opposing terminal. Then, the IP telephone delivers the URI of the IP TV camera service to an IP TV camera adaptor of its own IP telephone in order to make a video communication request. The resource record of the opposing terminal is associated with a telephone number of the opposing IP telephone, the record being obtained by connecting to a DNS server. The IP TV camera adaptor connects a call, via the IP telephone, to an IP TV camera adaptor of the opposing terminal, using the URI of the IP TV camera service of the opposing terminal and performs video image communication.
