THREE-DIMENSIONAL IMAGE DATA ENCODING METHOD AND DEVICE AND DECODING METHOD AND DEVICE

摘要

Disclosed are a data encoding method and device and decoding method and device; the encoding method being one that involves the encoding of three-dimensional image data into data units which consist of a header area and a data area and in which the header area contains type information showing the type of data contained in the data area, wherein encoding is carried out on reference-viewpoint image data and additional-point image data for providing a three-dimensional image, and wherein a header containing first unit type information constituting one form of type information defined in a legacy system is added to the encoded reference-point image data such that a first data unit is generated, and a header containing second unit type information constituting one form of type information not defined in the legacy system is added to the encoded reference-point image data such that a second data unit is generated.
