Description

  The present invention relates to an information processing apparatus and a control program that receive and record a broadcast.

  When watching a TV program, such as a commercial broadcast that is not of interest to the viewer, the remote controller is often used to switch to another channel, and after a certain period of time, the operation returns to the original channel. Is called. This operation is called zapping. When a program that was being watched during zapping is resumed, there is no way for the viewer to know it, and if the timing for returning the channel is wrong, the first part of the resumed broadcast is often missed.

  For this reason, a method has been proposed in which a program being viewed is registered, and when the viewer switches to another channel, the program is restored to the original channel after a predetermined time (see, for example, Patent Document 1). .

In addition, a plurality of tuners were recorded, and when a program desired by the viewer was recorded, when the program was switched, the switching timing was stored, and an operation for returning to the original desired program was performed. In some cases, a method has been proposed in which recorded data is reproduced in accordance with the timing so as not to miss viewing due to zapping. (For example, refer to Patent Document 2).

Further, in the method described in Patent Document 2, it is possible to prevent a desired program from being missed by zapping, but the program must always be recorded. Further, when returning to the original program after zapping, the recorded data is reproduced retroactively to the timing at which the program was switched, but it is necessary to record the timing at which the switching was performed. Furthermore, when the viewer performs zapping after the start of the non-interesting broadcast, the program is played back from the non-interested broadcast recording data even after the program return operation, or the viewer further It was necessary to perform operations such as fast-forwarding to the part of interest.

  Accordingly, an object of the present invention is to provide an information processing apparatus that prevents the desired program from being overlooked by zapping and that simplifies the reproduction of the desired program after the completion of zapping and improves convenience.

  To achieve the above object, an information processing apparatus according to the present invention comprises a plurality of receiving means for receiving broadcast data, selecting and outputting a desired program, and recording means for recording output data from the receiving means. Replay means for reproducing the output data from the receiving means and data recorded in the recording means, registration means for registering a specific program as an anchor program, and switching from the anchor program to another program. Switching detection means for detecting, and recording start means for starting recording of the broadcast data of the anchor program registered by the registration means by the recording means when switching of the program is detected by the switching means.

  Further, the control program of the present invention receives a broadcast data, selects a desired program, records the output data from the receiving means, and records the output data from the receiving means and the recording function. A reproduction function for reproducing the recorded data, a registration function for registering a specific program as an anchor program, a switching detection function for detecting that the anchor program has been switched to another program, and a program switching by the switching means And a recording start function for starting recording of the broadcast data of the anchor program.
