Abstract:
A reproducing apparatus for reproducing menu information from a recording medium, where the recording medium includes plural data units which are reproduced in sequence, the data units each being reproduced within a predetermined period of time, each data unit including a data pack array and a control pack, each of the data pack arrays including multiple data packs, the data packs comprising reproduction data including at least one of video data and sub-picture data, at least one menu information formed from the reproduction data being used for confirming contents of the video data and for selecting from among the video data, the menu information including a background image recorded as the video data and either a selection item or an action item represented by the sub-picture data, the control pack being positioned before the data pack array within each data unit so as to control reproduction of the reproduction data, the control pack recording control data for controlling the selection item or the action item, the reproducing apparatus comprising:a reader for reading reproduction data from a data pack array and control data from a control pack;a first extractor for extracting video data from the reproduction data read by the reader;a second extractor for extracting sub-picture data from the reproduction data read by the reader;a third extractor for extracting a status button color information table from the control data, said status button color information table having entries corresponding to one or more status buttons in said sub-picture;a fourth extractor for extracting a status button information table from the control data, said status button information table having entries corresponding to said status buttons in said sub-picture, wherein said status button information table includes status button information, and said status button information includes (a) status button position information for indicating a position of the corresponding status button in a menu, (b) adjacent status button information for describing a direction of a next selection for a status button which is in the user selection status, and (c) a status button command for describing a status command to be executed when the status button in the user selection status is activated;a fifth extractor for extracting from the control data the status button position information;a sixth extractor for extracting from the control data the adjacent status button information;a seventh extractor for extracting from the control data a status button command;a decoding circuit for decoding the sub-picture data extracted by the second extractor based on the control data read by the reader from the control pack; anda synthesizing device for generating reproduced menu information by synthesizing the sub-picture data decoded by the decoding circuit with the video data extracted by the first extractor.
