摘要： A method of controlling the selections on a reproducible control data structure with two different selection control methods. According to a first control method, single frame plural selectors, to each of which a numerical identifier has been added, are displayed. Branch tables grouping branch data according to selector numbers are provided. A user makes a selection by selecting a selector number. According to a second control method, plural sectors are displayed in a single frame. A user-specified selector and other selectors are provided for visually differentiating between the selectors as a means of prompting user confirmation of the specified selector. A selection confirmed by the user controls the selection by means of the branch data. Branch data usable by both the first control method and the second control method is grouped together by providing the branch data used by the second control method in the branch table used by the first control method.

摘要： An object of this invention is to provide a method for processing signals for an optical disc device and an optical disc device for immediately determining the on-track state of a main beam light impinging on an optical disc including land areas on which information is recorded, said optical disc being track-formatted to have a double spiral structure. In recording or reproducing information on or from the land areas while track-controlling a first reflected light (MB) based on a second reflect light (SB1) and a third reflect light (SB2), the phases of a sum signal (SUM) and a difference signal (DIFF) between a first push-pull signal (PP1) obtained from an output from a first split photo conductor (21) and a second push-pull signal (PP2) obtained from an output from a second split photo conductor (23) are compared to determine from the mutual phase relationship which land area is providing the first reflected light (MB).

摘要： In sequential processings of converting input picture data springs having unitary picture data in succession to picture data of a form adapted for displaying, storing the resultant picture data and then displaying the same in a display, a first detection data and a second detection data are monitored. The first detection data is indicative of commencement of the unitary picture data and is detected from the input picture data strings. The second detection data is indicative of termination of the conversion and is detected on the unitary picture data basis. If the second detection data has not been detected at the time when the first detection data has been detected, the unitary picture data detected with the first detection data is invalidated and the unitary picture data is left unprocessed. If the second detection data has been detected at the time when the first detection data has detected, the unitary picture data detected with the first detection data is transferred to a subsequent stage for implementing a subsequent processing with respect to the unitary picture data. As such, even if the picture data is inputted independently of a processing ability of a picture data processing apparatus, the data can be processed and outputted in conformity with the processing ability of the apparatus.

摘要： A combined memory medium is constructed by an optical disc used as a read-only memory, a cartridge for holding or receiving the optical disc, and a fixed memory which is held in the cartridge. The read or write operation for the fixed memory is carried out by structure different from that used for the optical disc so that the optical disc and the fixed memory constitute an integral memory medium. A combined memory medium drive apparatus includes the combined memory medium, a disc access block for reading out the data on the optical disc, a memory access block for performing reading or writing of data for the fixed memory, and a control block for interpreting an instruction sent from an external device to control the reading of data from the optical disc through the disc access block and the reading or writing of data for the fixed memory through the memory access block, in which the optical disc and the fixed memory are complementarily used. A combined memory medium playback apparatus includes the combined memory medium drive apparatus and a processing block for controlling it to process the data output therefrom, thereby being capable of performing writing. Because the control program is stored in the fixed memory, the drive apparatus and the playback apparatus are able to be operated with the combined memory medium alone, dispensing with the need for another memory medium.
