ABSTRACT:
A home gateway apparatus receives a request for desired contents from a program selection terminal storing a program guide at a home. When an IP packet addressed to a home network from the Internet is retrieved, it is checked whether the retrieved IP packet includes the desired contents, a reception of which is being requested. When the IP packet includes the desired contents, such contents are delivered to a TV apparatus via IEEE1394 network. When the IP packet does not include such contents, the IP packet is forwarded to other destination terminals in the home network.
