A terminal, allowing bidirectional communication with a gateway, receives information from the gateway through a forward satellite and sends information towards the gateway through a return satellite. The terminal comprises an antenna arrangement having a receive aperture for receiving signals from forward satellite and a transmit aperture for transmitting signals to return satellite. A controller computes a pointing direction from receive aperture towards the forward satellite based on the terminal's position and orientation, the antenna arrangement's geometry, and the forward satellite's orbital position; and computes a pointing direction from the transmit aperture towards the return satellite based on the computed pointing direction from the receive aperture towards the forward satellite and the return satellite's orbital position. The invention also relates to a system comprising a terminal and a gateway, and to a method for operating a terminal.

The present technology relates to a tuner IC capable of reducing the cost of a demodulation LSI.

A tuner includes an IF output terminal configured to output an IF signal of terrestrial broadcasting, a first output terminal configured to output the IF signal or one of BB signals that are output signals of satellite digital broadcasting and have orthogonal phases, and a second output terminal configured to output another of the BB signals. The present technology can be applied to a broadcast receiving system.

A process for improving network performance in systems that utilize secure domain name system (DNS) schemes. Encrypted DNS requests from devices in a local area network (LAN), such as a home or office, are submitted to a local proxy which stores cached DNS records. The proxy decrypts or examines at least a portion of the DNS request in order search for a matching record in its storage. Matching records are retrieved, encrypted, and supplied to the requesting device to satisfy the DNS request. If the proxy does not contain a matching record, the DNS query is encrypted and submitted to an external DNS server for resolution. The matching record can optionally be saved by the proxy prior to being supplied to the requesting device.
