Abstract: In a broadcast receiving apparatus and a channel changing method in a broadcast receiving apparatus, broadcast data corresponding to a selected broadcast program, included in a channel broadcast signal received as a result of broadcast program selection, is descrambled based on previously stored descrambling control information, thereby shortening scrambling time and reducing channel change time in the broadcast receiving apparatus.

Abstract: A method and system can access local network access devices whose IP (Internet Protocol) addresses are not registered to a DNS (Domain Name System) server using domain names. For this, a local network gateway registers the IP addresses and the domain names mapped to the IP addresses thereto. If a domain name contained in a received DNS query packet is registered to the local network gateway, the local network gateway changes a DNS query packet into a DNS answer packet containing an IP address corresponding to the registered domain name and then transmits the DNS answer packet to a local personal computer. Otherwise, the local network gateway passes the DNS query packet to an external network as it is.

Abstract: A method of controlling an ETT (Extended Text Table) information display on an EPG (Electronic Program Guide) screen for a digital TV to enable viewers to conveniently confirm existence of the ETT information included in an EPG information. The present invention detects an ETT packet by confirming packet identifiers (PIDs) of all packets received from a set top box, and displays existence of the ETT information only for an EPG program where the ETT packet is detected. Therefore, the viewers can easily confirm whether the ETT information exists by seeing the EPG screen only.
