摘要:
Video information intended to be reproduced on a television screen (1) often includes additional information such as graphics information (3) or subtitles (4) in addition to the main information such as film images (2). This additional information is transmitted separately, so that the user may choose whether the additional information is to be displayed or not. In the disclosed method the transmitted video signal comprises information relating to the duration (25) for which the additional information is to remain on the display. With this method the additional information can be displayed exactly for the duration of the desired time. When a video disc or tape is used for transferring video information, this is advantageous in trick modes, such as Fast Forward.

A 3D source device for outputting a three-dimensional image signal, the three-dimensional image signal comprising multi-view image data, the 3D source device comprising an input for receiving image data; a generator arranged to generate the three-dimensional image signal based on the image data, the three-dimensional image signal comprising a first component comprising multiple 2D images for use in stereoscopic viewing, a second component comprising overlay data and a third component defining disparity signaling information for use in overlaying image data over the respective ones of the multiple 2D images. New disparity signaling information in a further third component overrules the disparity signaling information in the third component.
摘要:
A method of recording an encoded bit stream, said encoded bit stream representing a plurality of video objects comprising a sequence of cells together constituting a part of an MPEG2 Program Stream, on a disc like record carrier, such as an optical disc. The method comprises recording video objects comprising a sequence of contiguously recorded cells, each cell comprising a unique cell identification number within a video object, recording of a playback sequence of cells that defines a playable program chain of cells, wherein said sequence comprises references to the cell identification numbers and recording navigation data within said cells comprising said cell identification numbers.The method further comprises dividing at least one previously recorded cell into new cells and/or overwriting at least one previously recorded cell at least partly with a new cell, assigning the at least one new cell with a cell identification number and recording a new playback sequence of cells employing the at least one new cell, the new playback sequence not necessarily employing an incremental numbering of cell identification numbers.Hereby a time consuming renumbering of all cells is being avoided.

A method of contiguously recording a sequence of ordered A/V information signals and corresponding management information signals on a disc-like recording medium of the write-once type, includes allocating a reserved area within a linear addressing space of the disc, contiguously recording the A/V information signals in a video recording area located succeeding the reserved area, recording corresponding management data in a temporary overview space succeeding the video recording area, generating a mapping table for mapping the recorded management data to address locations in the reserved area and recording the mapping table in the temporary overview space. When finalizing the disc, the recorded management information signals is copied to the reserved area in correspondence to the latest mapping table information and the remaining unrecorded sections of the reserved area is recorded with arbitrary data signals.
摘要:
The invention relates to an apparatus for receiving a first and second video signal. The first video signal represents a sequence of images having a first size, and the second video signal representing a sequence of images having a second size, the second size being smaller then the first size of the images. The apparatus combines said first and second video signal so as to obtain a composite video signal suitable for displaying on a display unit. The signal combination means being adapted to combine the first and second video signal while the size of the images corresponding to the second video signal remains unchanged.
摘要:
A method of recording information stores information on a multilayer record carrier of an opposte track path type (OTP). Logically the OTP disc has a single recording area, but physically a first part (54) is located on layer 0 (L0) and a second part (57) on layer 1 (L1). For recording a first amount ofdata dollowed by a second, larger, amount of data, the size of the first part is adapted to be at least equal to a data size of the second part by recording at least most of the first amount of data in the first part, including a filling area (49) in the first part, and recording at least most of the second amount of data in the second part. This has the advantage that a different amount of data can be accommodated on both layers, while a layer jump is easy.
摘要:
An information stream is encoded into a variable bit rate encoded information stream. The relation is estimated between the variable bit rate, the recording time and the storage capacity of a record carrier. The deviation of the estimated recording time from the true recording time is kept within predefined limits and accumulation of deviations from several successive recordings is prevented.

摘要:
Method and apparatus of contiguously recording a sequence of ordered AfV information signals, and corresponding management information signals, on a disc-like recording medium of the write-once type. The method comprises allocating a reserved area within a linear addressing space of the disc, contiguously recording the A/V information signals in a video recording area located succeeding the reserved area, recording corresponding management data in a temporary overview space succeeding the video recording area, generating a mapping table (39) for mapping the recorded management data to address locations in the reserved area and recording the mapping table (39) in the temporary overview space. The mapping table (39) used when recording information according to VCPS comprises a structure (39a), preventing the overwriting of the management data by recorders not familiar with VCPS. The structure is preferably formed by a mapping-table header field (39a) containing dummy data.
摘要:
To prevent dissemination of content stored on a DVD-RW disc, CPRM is provided. However, this does not provide a watertight system. The invention proposes to arrange a stream to be recorded such that the input for verification data and therefore verification data is different for different authorisation levels. Various embodiments for implementing the invention are disclosed and comprise re-arranging data packs to be recorded and/or modifying data in data packets.
