In a recording method, in particular, for recording still pictures, while classifying the still pictures and managing the still pictures classified, wherein still picture data and management information for managing that still picture data are recorded therein. The management information includes information for classifying the still picture data into a classifying unit, each, and also includes a file format of the still picture data classified into the classifying unit mentioned above.

In a video recording apparatus which records and reproduces digital TV broadcasting, an I-picture extraction processor that extracts packets containing I-pictures by analyzing a transport stream is arranged. Then, packets containing I-pictures is output, by reading predetermined amount of recorded data from an HDD in which recorded data is stored and by detecting start information and end information of the I-pictures. A stream for special reproduction is output by repeating the above-stated processes. With such arrangement, it is possible, even if data does not contain position information of I-picture, to execute special reproduction such as fast-forwarding reproduction for TV program data that is recorded as an MPEG-formatted transport stream.

In an apparatus of reproducing contents in which an encryption key is to be changed at predetermined intervals for copyright protection purpose, the contents can be reproduced or specially reproduced with no problem such as fast forward, and fast rewind. For special reproduction, data and key information needed therefor are made ready in advance, and using the data and the key information, the contents are specially reproduced. Alternatively, an encryption key generation rule is defined in advance for use in generation of an encryption key. By making any needed key information ready in advance from this rule, the contents can be reproduced and specially reproduced with no problem.

For providing a recording guidance method to increase an operability of a broadcast receiving apparatus, installing a removable hard disk in addition to an internal information recording medium built therein, within the broadcast receiving apparatus comprises a display portion and at least an install-type HDD 25 and a removable HDD (i.e., iVDR) 26, so as to enable recording of a broadcast program(s), selectively, the recording is conducted into the install-type HDD 25, in substation, if the removable iVDR 26 is not inserted therein when executing the recording programmed onto the said removable iVDR 26, as well as, displaying a message on the display portion, for prompting to insert the iVDR. Or, a message is displayed, for prompting to insert the iVDR, on the display portion, if the iVDR is not inserted into the apparatus when conducting the recording program into the iVDR.

Where a follow-up playback is realized for content data that is recorded by changing an encryption key at predetermined intervals for copyright protection, fast feed and playback operations are provided that can get close to a video scene of a present point of time. There are two areas on the memory in which to manage key information. The key information and seed information being written into a hard disk drive are held in memory in order to allow access to the key information and seed information even as they are written.
