Disclosed herein is a method for compressing point cloud data. The method includes quantizing input point cloud data, generating a global motion matrix based on the quantized point cloud data, applying the global motion matrix based on whether local motion compression is performed, and compressing data to which the global motion matrix is applied.

Method and apparatus for compressing point cloud data

Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

Apparatus and method for encoding and decoding moving picture using adaptive scanning

A method for transmitting scene composition information from an apparatus therefor in a multimedia communication system is provided. The method includes generating scene composition information comprising media attributes information and temporal information, and transmitting the scene composition information, wherein the media attributes information and temporal information is separated into different formats.

Apparatus and method for transceiving scene composition information in multimedia communication system

A method and an apparatus for reproducing video data are provided. The method includes the steps of extracting a coded video data stream and video data attribute information from the stored video file, extracting samples relevant to an expanded time layer from the extracted video data stream on the basis of the location information of the sample which allows for temporal layer access contailed in the video data attribute information, and restoring and reproducing the extracted samples.

Method and apparatus for reproducing video data

Methods and apparatuses for efficiently coding and decoding multi-view video are provided. A method of decoding multi-view video includes: interpreting from a received bitstream a block type indicating a method of determining a motion vector of a current block present in a current picture of the multi-view video; interpreting a first picture type indicating whether the current picture is a reference picture type for inter prediction; interpreting additional information of the current picture based on at least one of the interpreted first picture type and the interpreted block type; and reconstructing the current block and the current picture by using the additional information.

Method and apparatus for multi-view video encoding and method and apparatus for multiview video decoding

Provided are method and apparatus for transmitting and receiving a multimedia streaming service via a network. The method of providing a multimedia streaming service includes: dividing encoded data of a video including at least one of a two-dimensional (2D) video and a three-dimensional (3D) video into fragments; determining at least one of 3D signaling information for each fragment and relationship information to be used when the video refers to other videos; and continuously transmitting the fragments including the property information regarding the fragments and encoded video data.

Method for providing fragment-based multimedia streaming service and device for same, and method for receiving fragment-based multimedia streaming service and device for same

A method and apparatus transmitting stereoscopic image data according to a variable channel environment are provided. The method includes granting a priority to each of a plurality of frames constituting one image group; determining a number of transmittable frames based on a variable channel environment; and selecting transmittable frames from among the plurality of frames based on the determined number of transmittable frames and the granted priorities.
