Abstract:
1. A broadcasting signal receiving system comprising: a broadcasting signal receiving unit that receives a program broadcasting signal so as to obtain a video signal and an audio signal; an image pickup unit that photographs a viewer; a face image detecting unit that detects a face image from a photographed image of the viewer photographed by the image pickup unit; an authentication unit that compares the face image of the viewer detected by the face image detecting unit with a face image of each individual person registered in advance so as to authenticate the corresponding viewer; a recording reproducing unit that records a received program broadcasting signal so as to store the received broadcasting signal; a recording reproducing control unit that has a simple recording function for recording a program, which the viewer is viewing, in the recording reproducing unit, and sequentially deletes recorded data of the program in a recorded order whenever a predetermined time lapses, wherein when the face image is not detected by the face image detecting unit for a predetermined time or more, the recording reproducing control unit changes an operation mode of the broadcasting signal receiving system from a common mode to a power saving mode at a corresponding time, records a recording position of the corresponding time, and makes the received program continuously recorded by the recording reproducing unit in a state in which the simple recording function becomes invalid such that the face image is detected again by the face image detecting unit, when it is determined that the detected person is the same person as a first person based on the recognition result by the recognition unit, the recording reproducing control unit makes the operation mode of the system return to the common mode from the power saving mode at a corresponding time, and makes the recorded program return to the recording position so as to be reproduced while maintaining the common recording state, in the common recording state in which the simple recording function becomes invalid, when the face image is detected again by the face image detecting unit and it is recognized that the detected person is different from the first person based on the recognition result by the recognition unit, the recording reproducing control unit notifies the viewer that automatic recording is being performed, makes the operation input by a different person invalid, and displays a warning message indicating that the input is invalid on a screen while maintaining the common recording state.
