    Abstract: According to one embodiment, a storage system includes a host device, 2 storing medium. The secure storing medium includes: a memory provided with a protected first storing region which stores secret information sent from the host device, and a second storing region which stores encoded contents; and a controller which carries out authentication processing for accessing the first storing region. The host device and the secure storing medium produce a bus key which is shared only by the host device and the secure storing medium by authentication processing, and which is used for encoding processing when information of the first storing region is sent and received between the host device and the secure storing medium. The host device has the capability to request the secure storing medium to send a status.

  • Patent number: 8417093
    Abstract: On an optical disk, video object sets (VTST_VOBS) to be reproduced and video title set information (VTSI) serving as management information on the video object sets have been stored. In each video object set (VTST_VOBS), many data cells, each containing video, audio, and sub-picture data, are arranged. Management information on programs chains, which are combinations of programs to be reproduced one after another, has been written in a video title set PGC table (VTS_PGCIT). By referring to the program chain table (VTS_PGCIT) according to the user's input, the playback order of program chains can be changed, enabling the program chains to be reproduced one after another in various modes.
