Abstract: A multimedia information recording device is used for efficiently recording multimedia information (100) file storage area (111) on a recording medium (110). From the multimedia information given to the device, a data body DB and control information (HD and FD) are created and given to a file storage area writing section (106) where the data is written in parallel at a time on a free cluster in the file storage area. In the free area of each cluster where the data is written, dummy data is packed by a dummy data adding section (107) to absorb the difference between the first position of a cluster and the first position of the data in the cluster. Thus, data rewriting to eliminate this difference is avoided. Information for connecting plural clusters where data is written is created by a multimedia information file creating section (108), and the multimedia information is recorded in a multimedia information file on the recording medium.

Abstract: Printing of an image different from that designated by a user is prevented. Specifically, an image file in which image data has been stored and an order file in which ordering information that designates an image to be printed has been stored are recorded on a memory card. Stored in the image file is time stamp data indicating the time at which image data was stored in this image file. Stored in the order file is time stamp data indicating the time at which the ordering information was stored in the order file. If the time stamp data that has been stored in the order file indicates a time later than the time indicated by the time stamp data that has been stored in the image file, it is judged that the ordered image designated by the ordering information in the order file is the correct image designated by the user. This image is then printed.

Abstract: For example, in case of distributing contents by BS broadcast and recording a transmitted TS stream into a storage device, even if the stream has been encrypted, a trick play can be easily performed. A start marker packet and an end marker packet are sent just before and just after the start of an I picture. A unique PID is written in each of the start marker packet and end marker packet. Upon reception, a video packet of the I picture is identified by identifying the start marker packet and end marker packet. Upon recording, a TS packet of the I picture is detected from the start marker packet and end marker packet and marked. Thus, upon reproduction, a cluster including the TS packet of the I picture is known and a trick play can be performed by reproducing the I picture.
