DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus for making a recording reservation.

[0002]

2. Description of the Related Art In recent years, CS digital broadcasting has been started, and there has been an increasing demand for a magnetic recording / reproducing apparatus capable of digitally recording video and audio. On the other hand, using a magnetic recording / reproducing device capable of digital recording, that is, a moving picture experience using a video cassette tape.
A magnetic recording / reproducing apparatus capable of recording a bit stream signal of rts group 2 (hereinafter referred to as MPEG2) has been developed and announced.

[0003] Some broadcast programs include program-unit purchase broadcasts and broadcasts that can be received only by contracted persons. Such programs, especially broadcast programs purchased in units of programs, are subjected to limited reception (only those who have purchased the program and have not purchased the program cannot receive the program). Generally, when recording and purchasing a program-based purchased broadcast program, a viewer can purchase a program-based purchased broadcast program that the user wants to see and can record the program when the recording is permitted.

[0004] A case in which a conventional magnetic recording and reproducing apparatus records a broadcast program purchased in units of a program will be described below. FIG.
1 is a block diagram of a conventional magnetic recording / reproducing apparatus. FIG.
In the figure, 40 is a conventional magnetic recording / reproducing apparatus capable of digital recording, 42 is a tuner section, 43 is a transport decoder section for descrambling a broadcast (transport stream) of a channel received by the tuner, 4
Reference numeral 6 denotes an AV decoder unit that can convert an MPEG2 stream into a normal video / audio signal. Reference numeral 41 denotes a tuner unit 42, a transport decoder unit 43, and an AV decoder unit 46 which control reception of a selected channel when a program is selected. This is a control unit of the magnetic recording / reproducing device 40 that performs the operation. If the received channel is subjected to limited reception like a broadcast program purchased in units of programs and is a scrambled broadcast, the broadcast program purchased in units of a program is purchased with the IC card 44, the scramble is released, the reception is permitted, and the recording is performed. Based on the detection information from the reception / recording permission detection section 45 for detecting whether or not permission is given, the control section 41 causes the transport decoder section 43
And the descrambling can be controlled.

[0005] When a program is scheduled to be recorded, program schedule information is also sent from a broadcasting station at the same time as video and audio, and the control section 41 can decode the program schedule information and display it on the display section 52. In order to reserve a program, when a program is selected in the reservation setting section 50 from the program schedule information, the reserved program can be registered in the reservation registration section 51. Reference numeral 47 denotes a recording / playback unit, and a tuner unit 4
For the channel received at 2, the stream descrambled by the transport decoder 43 is recorded and played back by the recording and playback unit 4.
7 can be recorded on the recording medium 48.

The operation of the digitally recordable magnetic recording / reproducing apparatus configured as described above will be described with reference to FIG. First, in the program schedule table, a program schedule table for one week or several days from the current date has been transmitted. Using this program schedule table, it is possible to select a broadcast program purchased in units of programs to be reserved and recorded. A program can be reserved by selecting a broadcast program to be reserved for recording in units of a program from a program schedule table from a broadcasting station by the reservation setting unit 50 and purchasing the program. Then, the reserved program can be purchased by the reception / recording permission detection unit 45 and the reservation is registered in the reservation registration unit 51.

[0007] At this time, depending on the broadcast program purchased in units of programs, the program can be viewed, but recording prohibition / permission can be set. The recording prohibition / permission information is also transmitted from the broadcasting station together with a program schedule table. Depending on the program-based purchased broadcast program, when a program is reserved by the reservation setting section 50, a program whose recording is prohibited can be received but cannot be recorded. Also exists. When a program that can be recorded is reserved, at the start of the reserved program, the control unit 41 selects a channel reserved by reception permission from the reception / recording permission detection unit 45 of the IC card, and descrambles the data using the transport decoder unit 43. The data can be recorded on the recording medium 48 via the recording / playback unit 47.

[0008]

However, in the above-described conventional configuration, when the scheduled recording is set, the recording is permitted. However, when the recording is changed to the recording inhibition at the start of the program broadcast or before that, the scheduled recording is executed. Not done. At this time, when the person who has set the reservation tries to reproduce the program which has been pre-recorded later, it can be understood for the first time that the program has not been recorded. However, there is a problem that there is no means for knowing why the recording has not been performed. As an example of such a condition occurring, when a program is input to a program schedule table on the broadcast station side, an input error occurs when a recording-inhibited program is erroneously permitted to be recorded, or a recording permission condition is changed (for example, in a local area). It is conceivable that this may occur during limited recording.

[0009] The present invention solves the above-mentioned conventional problems. When the reservation recording is not executed due to the condition of the broadcasting station (for example, recording permission / prohibition) and the reservation cannot be made in the reservation recording unit. It is an object of the present invention to provide a magnetic recording / reproducing apparatus capable of knowing that recording cannot be performed due to a change from a broadcasting station by storing the above information.

[0010]

In order to achieve this object, a magnetic recording / reproducing apparatus according to the present invention comprises: a reservation setting section for making a recording reservation; a reservation registration section for registering a program reserved by the reservation setting section; And a reception recording permission detecting section for detecting whether or not reception is permitted and whether or not recording is permitted when a broadcast program purchased in units of a program is purchased, and a display section. When scheduled recording is attempted in accordance with the permission signal and the recording permission signal, if the scheduled recording is not executed due to the change of the reception permission signal and the recording permission signal from the reception recording permission detection unit, the scheduled recording is registered in the reservation registration unit. The reservation information, the reception permission signal from the reception permission detection unit, and the detection information based on the recording permission signal are displayed on the display unit.

With this configuration, when the scheduled recording is set, if the program reserved by the recording permission is changed to the recording prohibition at the start of the program broadcast or before that, the reservation recording is not executed, but the reservation information and the reception recording are not executed. When the detection information from the permission detection unit indicating that the recording permission condition is prohibited is displayed on the display unit, it is possible to know the reason why the reservation could not be made.

[0012]
