Abstract

Disclosed are a disc playback device and disc playback method, wherein playback of BD-J titles and other content on a BD-ROM disc, in particular movies and other main title content, can start automatically. In this disc playback device (100) which automatically plays content, a menu detecting means (17) analyzes the structure of a movie playlist at the start of the playback operation of a disc, and, in a case when the same play item is repeated multiple times, assess that this state is the menu state. A button determination executing means (18) executes button determinations if the menu detecting means (17) assesses that this state is the menu state.

Description

technical field [0001] The present invention relates to a disc player and a disc player method for playing data recorded in recording media such as BD-ROM (Blu-ray-Read-Only-Memory) discs. Background technique [0002] Existing documents have proposed that when using a DVD-ROM playback device in a vehicle environment, etc., when starting the playback operation of the optical disc, that is, after inserting the optical disc or turning on the power, etc., automatically start the playback of the content (for example, refer to the patent document 1). [0003] For example, when starting the playback operation of a DVD-Video disc, it is detected that the state has shifted to the menu, an Enter command is input, and an Enter command is also input when further shifting to a lower menu. As a result, the playback operation of the menu is automatically started. In this way, the playback of the content can be performed automatically without requiring the user to input a selection on th...
