Abstract
A middleware device and a method of supporting compatibility of devices on a home network are provided, in which the compatibility of all kinds of devices based on UPnP and web service is supported by protocol conversion. The middleware device includes a discovery unit receiving discovery messages based on different protocols and converting each of the discovery messages to a message based on a protocol that can be processed by a device to which the messages are to be transmitted; a description unit creating a description file of a predetermined device requested from the UPnP and the web service and converting the created description file such that it can be processed by a device having requested the description file; and an information management unit managing service information and information on devices existing on the home network on the basis of the discovery message and the description file.
