摘要:
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 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).

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).
摘要:
A device for processing video information has an input unit (112) for receiving the video information having low dynamic range [LDR] video data and/or high dynamic range [HDR] video data, and a video processor (113) for generating a display signal for display in a LDR display mode or HDR display mode. Graphics data is processed for generating an overlay for overlaying the video data. The input unit receives graphics processing control data comprised in the video information, the graphics processing control data including at least one HDR processing instruction for overlaying the graphics data in the HDR display mode. The video processor is constituted for adapting the processing when overlaying the graphics data in dependence on the specific display mode and the HDR processing instruction. Advantageously the source of the video information is enabled to control the processing of graphics in HDR display mode via the HDR processing instruction.

The invention relates to a method for generating a three-dimensional (3D) video signal to enable simultaneous display of a 3D primary video signal and a secondary video signal on a 3D display, the 3D primary video signal comprising a base video signal and a subsidiary signal enabling 3D display, and the method comprising the steps of providing as the secondary video signal a two-dimension (2D) secondary video signal, and formatting the base video signal, the subsidiary signal and the 2D secondary video signal to generate the 3D video signal.
摘要:
An apparatus generates an image signal in which pixels are encoded in N-bit words which encode at least a luma per pixel. A receiver (201) obtains high dynamic range pixel values in accordance with a first color representation in M-bitwords. A first generator (203) includes the high dynamic range pixel values in the image signal in the N-bit words according to a second color representation. A second generator (205) includes in the image signal an indicator that high dynamic range pixel values are encoded. In some examples, the high dynamic range pixel values may be provided in a segment that can alternatively contain high or low dynamic range pixel values, and the indicator may indicate which type of data is included. The approach may e.g. facilitate introduction of high dynamic range capability into e.g. HDMI systems.

A method of creating a three-dimensional image signal including receiving a first image component, receiving a second component for creating a three-dimensional image in combination with the first image component, receiving a text component for including in the three-dimensional image, receiving a data component comprising location information describing the location of the text component within the three-dimensional image, and creating a three-dimensional image signal comprising the first image component, the second component, the text component, and the data component. The signal is rendered by rendering a three-dimensional image from the first image component and the second component, the rendering including rendering the text component in the three-dimensional image. The rendering of the text component includes adjusting three-dimensional parameters of the three-dimensional image in the location of the rendered text component.
摘要:
A three dimensional [3D] video signal (41) is provided for transferring to a 3D destination device (50). Depth metadata is determined indicative of depths occurring in the 3D video data, which depth metadata includes a near value indicative of depths of video data nearest to a user. The 3D video signal, which comprises the 3D video data, now also includes the depth metadata. The 3D destination device (50) is enabled to retrieve the depth metadata, to provide auxiliary data, and to position the auxiliary data at an auxiliary depth in dependence of the retrieved metadata for displaying the auxiliary data in combination with the 3D video data such that obscuring the auxiliary data by said nearest video data, and/or disturbing effects at the boundary of the auxiliary data, is avoided.
摘要:
An apparatus generates an image coding signal comprising for each image a first pixelized picture and a second pixelized picture having a luminance component and a chroma component. The apparatus comprises a first picture processor (203, 211) which includes image encoding data for an encoded first image in the first pixelized picture. A second picture processor (205, 207, 209, 211) includes dynamic range extension data in the second pixelized picture. The dynamic range extension data may be dynamic range extension data included in a chroma component of the second pixelized picture for generating an increased dynamic range image on the basis of the encoded first image. The compensation data may e.g. be compensation data for correcting another LDR-to-HDR transform, e.g. a prefixed global gamma transformation. The dynamic range extension data may be included in a luminance component and comprise data representing a dynamic range extension transform for generating an increased dynamic range image from the encoded first image.
