Abstract

Provided is an in-home receiving terminal system capable of detecting that a receiving terminal device is outside a subscriber'"'"'s house, and restricting viewing of cable television broadcasting by the receiving terminal device outside the subscriber'"'"'s house. In the in-home receiving terminal system comprising a main terminal device and a sub-terminal device for receiving digital cable television broadcasting, the main terminal device and the sub-terminal device being connected to an in-home network, a link detecting portion of the sub-terminal device detects the status of a link connection with the in-home network, and a terminal control portion of the sub-terminal device controls activation/deactivation of a television reception tuner based on the detected status of the link connection.

Claims

1. An in-home receiving terminal system comprising a main terminal device and a sub-terminal device for receiving digital cable television broadcasting, the main terminal device and the sub-terminal device being connected to an in-home network,

wherein the sub-terminal device includes:

a tuning unit for receiving the digital cable television broadcasting;

a link detecting unit for detecting the status of a link connection with the in-home network; and

a terminal control unit for controlling activation/deactivation of the tuning unit based on a notification from the link detecting unit, regarding the status of the link connection.

2. The in-home receiving terminal system according to claim 1, wherein the terminal control unit deactivates the tuning unit when the sub-terminal device is prohibited from establishing the link connection with the in-home network.

3. The in-home receiving terminal system according to claim 2,

wherein the sub-terminal device includes:

an authentication information holding unit for holding first authentication information; and

a networking unit for controlling the link connection with the in-home network, and

wherein the networking unit establishes no link connection with the in-home network when the first authentication information differs from second authentication information issued by the main terminal device.
