Disc player device
View Patent ↗According to the present invention, provided is a disc player device ( 100 ) that automatically performs a user operation for playing a first play that is a title played before playing of a main part or display of a menu, faster than playing at a normal speed after the power is applied. A signal processing unit ( 15 ) is provided with a menu detection unit ( 17 ) to analyze structure of various data and detect a menu state, a main part detection unit ( 18 ) to detect playing state of a main part from the various data, and a user operation unit ( 19 ) to automatically perform a user operation for playing a title currently being played faster than playing at a normal speed until a menu state is detected by the menu detection unit ( 17 ) or a playing state of a main part is detected by the main part detection unit ( 18 ) when the signal processing unit ( 15 ) determines that a First Playback exists after the power is applied.
1. A disc player device which plays a disc managed on a basis of plurality of titles including at least a menu and a main part, the disc player device comprising:
a signal processing unit which obtains data held in the disc and performs signal processing of the data;
a menu detection unit which analyzes a structure of the data and detects a menu state;
a main part detection unit which detects a playing state of a main part from the data; and
a user operation unit which, automatically performs a user operation for playing a title currently being played faster than playing at normal speed until the menu state is detected by the menu detection unit or the playing state of the main part is detected by the main part detection unit when the signal processing unit determines a First Playback exists after a power is applied, wherein:
the user operation automatically performed by the user operation unit is at least one of Menu Call, Chapter Search, Time Search, Skip to Next point, and Forward Play, and wherein
the user operation unit repeatedly performs following steps 1 to 5 until a top menu or a main part is detected;
(step 1) performing the Menu Call when the Menu Call is not restricted by UO mask in a movie title being played, and
performing step 2 when the Menu Call is restricted by the UO mask,
(step 2) performing the time Search to transit to a final time of a final chapter in the movie title being played when the Time Search is not restricted by UO mask in the movie title being played, and
performing step 3 when the Time Search is restricted by the UO mask,
(step 3) confirming whether or not a plurality of chapters exist in the movie title being played when the Chapter Search is not restricted by UO mask in the movie title being played, and performing the Chapter Search to transit to the final chapter in the title when the plurality of chapters exist, and after that performing step 4, and
performing step 4 without performing the Chapter Search when the Chapter Search is restricted by the UO mask,
(step 4) performing the Skip to Next point until transition to a final point in the title when the Skip to Next point is not restricted by UO mask in the movie title being played, and performing step 5, and
performing step 5 without performing the Skip to Next point when the Skip to Next point is restricted by the UO mask,
(step 5) performing a play at a feasible speed faster than the normal speed to a final time of a chapter being played when the Forward Play is not restricted by UO mask in the chapter.
2. The disc player device according to claim 1 , wherein
the main part detection unit determines whether or not a screen is in the playing state of the main part based on disc management information held in the disc.
3. The disc player device according to claim 2 , wherein
the main part detection unit detects transition to the main part when one of the following conditions (1) to (6) is met:
(1) a POP-UP MENU exists in a playlist,
(2) a play item has a duration of more than a specific time length and UO mask does not exist,
(3) a play item has a duration of more than a specific time length and a plurality of chapters exists,
(4) a play item has a duration of more than a specific time length and a plurality of subtitles exists,
(5) a play item has a duration of more than a specific time length and a plurality of types of sounds exists, and
(6) a play item has a duration of more than a specific time length and playing times between a playlist and the play item are substantially the same.
4. The disc player device according to claim 1 , wherein
the user operation unit automatically performs the user operation during a movement of a vehicle.
5. The disc player device according to claim 1 , wherein
the disc includes a BD-J title.
6. The disc player device according to claim 1 , wherein
each of the plurality of titles is composed of a plurality of playlists, and
the menu detection unit determines that a screen is in the menu state when a playlist of a specific title is repeatedly played more than a specific number of times.
