Abstract: The present disclosure relates to an information processing device and method capable of suppressing an increase in processing load when randomly accessing scene descriptions. As update information for updating spatial arrangement information for arranging at least one 3D object in a 3D space, initial value reference difference information that is difference information which uses an initial value of the spatial arrangement information as a reference, or post-update information in which an update to the initial value reference difference information is reflected in the initial value of the spatial arrangement information, is generated. Then, an update file which stores the update information is generated, and the initial value reference difference information or the post-update information is stored in the update file as a random access point. The present disclosure can be applied in, for example, an information processing device, an information processing method, or the like.

Abstract: The present disclosure relates to an information processing apparatus and method capable of suppressing an increase in a load of a reproduction process. A scene description file that describes a scene of 3D object content is generated, the scene description file including information associated with Media Presentation Description (MPD) that stores metadata of the 3D object content distributed by using Moving Picture Experts Group Dynamic Adaptive Streaming over HTTP (MPEG DASH) and information regarding encoding of Representation included in Adaptation Set in the MPD. Furthermore, the scene description file is analyzed, the 3D object content to be decoded is selected on the basis of the information regarding the encoding of the Representation, and the encoded data of the selected 3D content is decoded. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, or the like.

Abstract: A scene descriptive file describing a scene of 3D object content is generated, in the scene descriptive file, timed metadata identification information indicating that metadata of an associated external file changes in a time direction being stored in an MPEG_media extension, and timed metadata access information associating a camera object with the metadata being stored in the camera object. Furthermore, timed metadata that changes in the time direction is acquired on the basis of the timed metadata identification information and the timed metadata access information stored in the scene descriptive file, and a display image of the 3D object content is generated on the basis of the acquired timed metadata. The present disclosure is applicable to, for example, an information processing device, an information processing method, or the like.

Abstract: There is provided an information processing apparatus and method capable of more easily comparing 3D objects. Comparison information which is information for displaying a plurality of 3D objects of 6DoF content in a comparable manner is generated. Further, the plurality of 3D objects of the 6DoF content is displayed in a comparable manner on the basis of comparison information which is information for displaying the plurality of 3D objects in a comparable manner. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, an information processing system, and the like.

Abstract: Provided is an appropriate viewing experience according to the intention of a provider. A metadata generation unit (122) generates timed playback information indicating a display order along time passage for playback of each scene of 6DoF content including a three-dimensional model in a three-dimensional space, and modified timed metadata including recommended viewing information indicating a viewpoint position and a line-of-sight direction at each time point along time passage for playback, and generates association information indicating that the timed playback information and the modified timed metadata correspond to each time point along the time passage for playback.

Abstract: A picture data compressing device has picture data divided by a blocking circuit 1 in to a plurality of blocks, each block consisting of a pre-set number of pixels and shuffled by a shuffling circuit 2. The blocked and shuffled data is transformed by a DCT circuit 3 into data in the frequency domain and re-quantized by a quantization circuit 4, thereby compressing the picture data. A red detector 6 determines whether a block from the shuffling circuit 2 is the red-based block. If the red detector 6 detects a red-based block, a controller 7 controls the quantization circuit 4 so that the quantization step of the quantization circuit 4 will become finer. Thus, the data of the red-based block susceptible to block distortion may be quantized with a finer quantization step for improving reproduction and alleviating block distortion.

Abstract: A picture reproducing device in which a still picture can be recorded/reproduced to high picture quality without requiring a dedicated still picture processor or a RAM configured for storing picture data for processing by the dedicated still picture processor. Input video signals are all processed with DCT in a DCT/IDCT processor 4 as a continuous frame picture from one transform block to another and quantized by the quantizer/dequantizer 5 so as to be then recorded on a recording medium. Reproduced signals from the recording medium are dequantized by the quantizer/dequantizer 5 to give coefficient data which are processed with inverse DCT by the DCT/IDCT processor 4 to generate playback video signals. Responsive to the coefficient data based results of motion detection effectuated from one transform block to another, the playback video signals are outputted as playback video signals from the blocking shuffling/deblocking deshuffling processor 2.
