摘要:
A method is described for recording information on a multi-layered optical disc (2), the disc comprising two storage spaces (LO, L1) in adjacent storage layers (40, 41). Data to be recorded are received from a source. On recording, the data are organized to form cells (35), each cell corresponding to a certain amount of data. The cells are first recorded in the first storage space (LO) until the last storage address (N) of the first storage space, and then the recording process makes a transition to the first storage address (N+1) of the second storage space. The size of the last cell to be recorded in the first storage space is determined in relationship to the size of the remainder part (R) of the first storage space, such that the transition from the first storage space to the second storage space corresponds to a cell boundary (34).
摘要:
A method for copying information from a multi-layered optical source disc (2S) to on a multi-layered optical target disc (2T) is described. A first portion (67) of the source data is located in a first source storage space (LsO), and a second portion (68) of the source data is located in a second source storage space (LsI). The first source data portion has a logical end address (M) smaller than the physical end address (Nt) of the first target storage space (LtO). All source cells from the first source storage space are recorded into a first target data portion (77) of the first target storage space. The remainder portion (74) of the first target storage space is defined as a dummy data portion. Then, the cells from the second source data portion (68) are recorded into a second target data portion (78) of the second target storage space (LtI).

A system for transferring 3D video information has a transmitter (100) to broadcast a signal (104) to a receiver (110). The 3D video information includes auxiliary data for display in an overlay area on the 3D video data, like subtitles. The 3D video data has a left view and a right view arranged in a 2D frame in a main arrangement, e.g. side-by-side. An auxiliary left and right view of the auxiliary data are arranged in an auxiliary data stream according to a 2D transmission format in an auxiliary arrangement that corresponds to the main arrangement, e.g. also side-by-side. In addition, a 2D version of the auxiliary data and auxiliary disparity data indicative of the disparity to be applied to the 2D version of auxiliary data when overlayed on the left view and the right view is included in the transport stream. Advantageously the receiver may use a suitable version of the auxiliary data based on the receiver processing architecture.

摘要:
A medium access device includes a writer configured to write information in a logical storage space of a storage medium which has a physical storage space comprising two or more layers of physical storage locations. Each physical storage location has a physical address. The logical storage space includes storage locations within a first layer of the layers and within a subsequent layer of the layers. The storage locations in the logical storage space have contiguously numbered logical addresses. The access device further includes an address limit memory containing at least a value for a parameter indicating maximum value of the logical addresses of the storage locations in the first layer; and a processor configured to change the maximum value in the address limit memory and to provide an output when the maximum value cannot be changed to avoid attempting changing the maximum value.
摘要:
A method and apparatus for recording information on a multi-layer record carrier includes recording control information in a control information zone before recording user information after a layer jump. This ensures that all user information can be read and recorded reliably, while the storage capacity of the record carrier for storing user information is not reduced.
摘要:
A device for recording information writes marks in a track on a record carrier of a re-writable type. The device records the information according to a predefined recording format like DVD for constituting a recording area containing user data preceded by a lead-in zone. The device has a formatting unit (36) for formatting the record carrier. First it is detected if the record carrier has been recorded before. If so, a size is determined of a pre-existing contiguously written area that extends from the beginning of the recording area. The formatting includes writing data on the record carrier indicating that the recording area does not contain user data. Formatting status information is provided on the record carrier indicating the size of the pre-existing contiguously written area.
摘要:
A method and device for recording information signals on a partly recorded writable record carrier (11), e.g. an optical disc. An information signal represents at least one information unit. The record carrier has a recording track which comprises preformed track position information indicative of locations for recording the information units. From the information signal a modulated signal is generated, and the recording track is scanned for recording the modulated signal. If recording is after and adjacent an existing recorded unit, linking information is read from an end boundary area of the existing recorded unit and used for logically generating the modulated signal. If recording is before and adjacent to an existing unit, linking information is read from a begin boundary area of the existing unit and thereafter used for logically generating the modulated signal.
摘要:
A device for recording information on a record carrier (11) is arranged for formatting a multilayer record carrier. The device has formatting means (16) for formatting the record carrier according which formatting includes de-icing by, in the event that locations in the user data area have not yet been recorded, writing dummy data (60) on the locations. The formatting means (16) determine a first radial position (50) and a first layer (40), which first radial position is indicative of a location on the first layer on which user data will be recorded first according to a predefined recording format. Subsequently said de-icing is started by writing of dummy data on a second layer (41) of the record carrier at the first radial position, opposite the location of the first user data (55). Hence a de-iced area (58) is created opposite the user data (55).
摘要:
When writing on a recordable medium the recorder can encounter write errors. When a write error occurrs the record carrier is discarded. By ignoring write errors in sections of the record carrier comprising unused information, for instance sections of the lead-in or lead-out the record carrier no longer needs to be discarded.
