Abstract
Data receiving device and method in which data is received through a broadcast network, the data is reconstructed into packets usable on a computer, and the packets are output to the computer, directly or through a local area network. The reconstructed packets are preferably in the format of Internet Protocol (IP) packets. A destination address allocated to the data receiving device on the broadcast network is converted, via the data receiving device, to an IP address allocated to a personal computer on the Internet.
Claims7
Data receiving apparatus for receiving data from a broadcast network and outputting the received data to a computer coupled to said data receiving apparatus through a local area network (LAN), said apparatus comprising:
- routing means for routing, through the Internet via a telephone network, a request from the computer to a server on the Internet, said server being associated with the broadcast network;
- receiving means for receiving response data through the broadcast network in response to the request, said response data including a destination address in a header portion thereof, said destination address having been allocated on the broadcast network;
- packetizing means for packetizing the received response data into packets in accordance with the Internet Protocol;
- LAN interface means to interface said data receiving apparatus with said local area network;
- and
- rewriting means for rewriting header information of the response data, including rewriting said destination address to an Internet Protocol address, allocated on the Internet, of the computer that made the request;
- wherein said routing means routes the packets of the received response data with the rewritten header information through the local area network to the computer that made the request.
