HD DVD video has been stipulated two kinds of contents, that is, and and standard content and senior content.Therefore, when content wanted reproduced, the content type determining unit 131 of information reproduction device 110 was defined as the type of object content to begin to handle.
Figure 10 is the process flow diagram of example that the process of the type of having determined object content is shown.
(1) when dish D is inserted into, determines whether the DISCID.DAT file exists (step S21).Exist if determine DISCID.DAT, then object content is defined as senior content (step S22).
(2), then determine VMG_ID (a kind of standard content id information) whether effectively (step S23) if do not determine to exist DISCID.DAT.If VMG_ID is effective, then object content is defined as standard content (step S24).If VMG_ID is invalid, then object content is defined as the unidentified content that goes out (neither senior content the content of non-standard content) again (step S25).
C. reproduction processes (Figure 11)
Figure 11 is the process flow diagram that the content playback process is shown.
(1) reads DISCID.DAT file (step S31).
(2) determine whether display is defined (step S32).Whether be defined according to display, select the ferret out file.Display has been defined the display part that means video/audio output apparatus 120 and has been connected with information reproduction device 110 and can be used.
(3), then search for VPLST$$$.XPL, and initial play is determined (step S41 to S45) if display is defined.Three numerals of " " expression.
-determine whether the value of the SEARCH_FLG in the DISCID.DAT file is 1 (step S41).Whether the value according to SEARCH_FLG is 1, and flow process proceeds to step S43 or S42.
Play list file (VPLST$$$.XPL) (step S42) under the particular category among the whole permanent storage ST of-search.
Play list file (VPLST$$$.XPL) (step S43) under the direct ADVOBJ catalogue in dish of-search.
-determine whether to have been found that one or more VPLST$$$.XPL.If find one or more VPLST$$$.XPL, then determine initial play (step S45).Specifically, the VPLST$$$.XPL with maximum number is defined as initial play, and begins to reproduce.
(4) this display of ifndef is then searched for APLST$$$.XPL, and determines this initial play (step S51 to S55).In these steps, APLST$$$.XPL is used to the VPLST$$$.XPL that uses among the alternative steps S41 to S45.
For example, if do not find APLST$$$.XPL, then stop to reproduce (step S56).Determine the action of this moment according to the configuration information in the configuration information storage unit 117.
As mentioned above, can reproduce according to the application type of content and comprise the two many content discs of HD DVD video content and DVD video content.
