  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of a composite recording / reproducing apparatus according to the first embodiment of the present invention.

  In FIG. 1, a composite recording / reproducing apparatus 1 is configured to be able to record / reproduce video / audio information to / from a hard disk 1 and an optical disk 2, respectively. A hard disk drive 3 as a hard disk apparatus and an optical disk as an optical disk apparatus. Drive 4, HD (High Definition) decoder 5, down converter 6, SD (Standard Definition) standard encoder 7, CPRM (Content Protection for Recordable Media) circuit 8, key memories 9 and 10, SD decoder 11, Scramble circuit 12, buffer memory 13, HD decoder 14, descramble circuit 15, digital tuner 16, flash memory 18, remote controller 19, light receiving unit 20, an OSD circuit 21, and a system controller 22.

  The hard disk drive 3 records / reproduces video / audio information with respect to the hard disk 1, and the optical disk drive 4 records / reproduces video / audio information with respect to the optical disk 2. The HD decoders 5 and 14 decode (decode) an HD stream compressed (encoded) by the MPEG method. The down converter 6 is an image quality conversion circuit that converts HD video data related to HD size (1920 pixels × 1080 pixels) video into SD data related to SD size (720 pixels × 480 pixels) video. The SD encoder 7 compresses (encodes) the SD data relating to the SD size video converted and output by the down converter 6 according to the MPEG system to generate an SD stream.

  The CPRM circuit 8 performs encryption and decryption of various data recorded on the optical disc 2 in order to prevent copying according to CPRM. The key memory 10 or the key memory 9 stores a scramble key used for HD stream scramble processing or scramble data descramble processing. The scramble process refers to a process of converting content information indicating a predetermined video and audio into information that cannot indicate the predetermined video and audio alone, that is, scramble information. That is, the scramble information is not information indicating content information itself, but becomes information indicating various videos and sounds for the first time by performing data processing together with the scramble key. Therefore, as long as the scramble information is generated, the copyright of the content can be appropriately protected. The SD decoder 11 decodes the SD stream from the CPRM circuit 8 compressed (encoded) by the MPEG method to generate SD data related to an SD size video.

  The digital tuner 16 selects a digital high-definition broadcast signal of a desired broadcast station from among digital high-definition broadcast signals received via an antenna (not shown) and outputs it as an HD video / audio signal (HD stream). The buffer memory 13 can temporarily store the HD stream from the digital tuner 16, and the stored HD stream can be stored at a desired timing (for example, the scramble from the key memory 10 input to the scramble circuit 12). It is possible to output to the scramble circuit 12 at a timing according to the key).

  The scramble circuit 12 performs a scramble process on the HD stream read from the buffer memory 13 based on the scramble key read from the key memory 10. As a result, scramble data is generated. The descrambling circuit 15 performs descrambling processing on the scrambled data read from the hard disk 1 based on the scramble key read from the key memory 9. The descrambling process is a process for performing a process opposite to the scramble process on the scrambled data. As a result, an HD stream is generated from the descramble circuit 15 and input to the HD decoder 14. Decoded with From the HD decoder 14, data relating to HD image quality video is input to the OSD circuit 21 and supplied to the display device 23 via a displayable video signal. Accordingly, the high-definition video is displayed on the display device 23.

The recording format or the like for the optical disc 2 is obtained from the disc information, set in the flash memory 18 (step M19), the hard disc drive 3 is driven, and the program selected by the digital tuner 16 is recorded on the hard disc 1 with SD image quality ( Step M20). That is, the system controller 22 decodes the HD stream obtained by the digital tuner 16 into HD data by the HD decoder 5, inputs it to the down converter 6, converts it into SD data, and further converts the SD stream by the SD encoder 7. The SD stream from the SD encoder 7 is recorded on the hard disk 1 in accordance with the recording format that is encoded into the stream and read from the flash memory 18.

  According to the third embodiment described above, the timing for converting the HD video signal and audio signal information (HD stream) recorded on the hard disk into the SD video signal and audio signal information (SD stream). When the device is turned off (when the power is turned off from the user's perspective), the user can set the HD image quality to the SD image quality at the date and time set by the user. Therefore, while the user is not using the device, the HD video signal and audio signal information (HD stream) recorded on the hard disk is automatically converted into the SD video signal and It can be converted into audio signal information (SD stream) and recorded on an optical disk or hard disk. It is possible to omit the temporal waste of recording work of the conversion work and an optical disc or a hard disk to the SD image quality from the quality.

  That is, according to the third embodiment, the user sets the date and time zone for conversion from HD image quality to SD image quality in advance, and the conversion and recording to the optical disk or hard disk is performed when the apparatus is turned off. Therefore, it is possible to efficiently perform automatic conversion from HD image quality to SD image quality and automatic recording to an optical disk or a hard disk without restricting the user's operation. Therefore, it is possible to save time for converting from SD to SD image quality and recording to an optical disk or hard disk. Also, since the program recorded on the hard disk with HD image quality is stored on the hard disk until the date and time of conversion from HD image quality to SD image quality set by the user, it can be viewed any number of times until the change date and time comes. It becomes possible.

  In the first, second, and third embodiments, in a composite recording / reproducing apparatus including a hard disk device and an optical disk device, HD image quality information recorded on the hard disk is converted into SD image quality information. In the above description, the SD image quality information is recorded on the optical disk or the like. However, it is conceivable to perform the same processing by connecting a single hard disk device to the single optical disk device. Since the control relationship becomes complicated, it is not preferable to connect a single hard disk device to a single optical disk device and perform the same processing, which is considerably difficult.

  The present invention converts an HD image quality information recorded on a hard disk into an SD image quality information and converts the SD image quality information into an optical disk or the like for a composite recording / reproducing apparatus including a hard disk device and an optical disk device. It can be used for a function for recording.
