Abstract

To provide a digital broadcast receiver capable of executing higher value-added functions. [Solution] The device comprises a first broadcast receiving unit that receives broadcast waves of a first broadcast service, a first separation unit that separates encoded program video data and time control information from the received broadcast waves, a first video decoding unit that decodes the encoded program video data to reproduce program video information, a second broadcast receiving unit that receives broadcast waves of a second broadcast service, a second separation unit that separates encoded program video data and time control information from the received broadcast waves, a second video decoding unit that decodes the encoded program video data to reproduce program video information, a current time information generating unit that generates current time information based on either the first time control information or the second time control information, a presentation processing unit that can input the first program video information, the second program video information, and the current time information, perform appropriate selection processing and / or superimposition processing, and output as video information, a display unit that displays the video information, and a control unit.

Claims

[Claim 1] A method for storing content in a broadcast receiving device that receives broadcast program content, A receiving step of receiving the aforementioned broadcast program content, A storage step for storing the broadcast program content received in the reception step, An output step for outputting the broadcast program content stored in the storage step to an external device, Equipped with, With respect to the broadcast program content stored in the storage step, if the broadcast program content received in the reception step is content that is protected to allow a predetermined number of copies, the broadcast program content received in the reception step is recorded and stored in a state that allows for nine copies and one move, and is encrypted so that it can be played back only by the broadcast receiving device. The storage of the broadcast program content in the storage step can be performed in a storage unit located at the output destination of an IP interface, which is configured with Ethernet-compatible hardware provided in the broadcast receiving device, and the storage of the broadcast program content in the storage unit located at the output destination of the IP interface in the storage step, in an encrypted state so that it can be played back only by the broadcast receiving device, and the output of the broadcast program content stored in the storage unit located at the output destination of the IP interface in the storage step, in an encrypted state so that it can be played back only by the broadcast receiving device, to the external device in the output step can both be performed via the same IP interface, which is configured with Ethernet-compatible hardware. In the storage step, the stored broadcast program content is recorded in the storage unit at the output destination of the IP interface in an encrypted state so that it can be played back only by the broadcast receiving device, and then the stored broadcast program content is output from the broadcast receiving device after the broadcast receiving device has finished storing it by playing it back. In the output step, the output control state to the external device via the IP interface is as follows: In the storage step, the stored broadcast program content is recorded in the storage unit at the output destination of the IP interface in an encrypted state so that it can be played back only by the broadcast receiving device. Subsequently, when the stored broadcast program content is output from the broadcast receiving device after the broadcast receiving device has finished storing it by playing it back, in the output step, the output for viewing in an encrypted state when outputting to the external device via the IP interface is permitted when the IP address of the external device is within the same subnet as the IP address of the broadcast receiving device, and prohibited when the IP address of the external device is outside the same subnet as the IP address of the broadcast receiving device. However, if within a predetermined period the conditions are met that the external device is connected within the same subnet as the IP address of the broadcast receiving device and is paired as a device that can be viewed even outside the same subnet as the IP address of the broadcast receiving device, then output is permitted even if the IP address of the external device is outside the same subnet as the IP address of the broadcast receiving device. This is a first output control state. In the storage step, the stored broadcast program content is recorded in the storage unit at the output destination of the IP interface in an encrypted state so that it can be played back only by the broadcast receiving device, and then the stored broadcast program content is output from the broadcast receiving device after the storage is completed by playback by the broadcast receiving device. In the output step, when copying to the external device via the IP interface, a second output control state is established in which copying is permitted when the IP address of the external device is within the same subnet as the IP address of the broadcast receiving device, and copying is prohibited when the IP address of the external device is outside the same subnet as the IP address of the broadcast receiving device. The storage step involves recording the stored broadcast program content in the storage unit at the output destination of the IP interface in an encrypted state so that it can be played back only by the broadcast receiving device, and then, when the stored broadcast program content is output from the broadcast receiving device after the broadcast receiving device has finished storing it, the output step involves moving the content to an external device via the IP interface, which includes a third output control state that allows the move when the IP address of the external device is within the same subnet as the IP address of the broadcast receiving device, and prohibits the move when the IP address of the external device is outside the same subnet as the IP address of the broadcast receiving device.
