    Abstract: The present technology relates to an encoding device and method, a decoding device and method, and a program capable of realizing sense-of-distance control based on intention of a content creator.
    The encoding device includes: an object encoding unit that encodes audio data of an object; a metadata encoding unit that encodes metadata including position information of the object; a sense-of-distance control information determination unit that determines sense-of-distance control information for sense-of-distance control processing to be performed on the audio data; a sense-of-distance control information encoding unit that encodes the sense-of-distance control information; and a multiplexer that multiplexes the coded audio data, the coded metadata, and the coded sense-of-distance control information to generate coded data. The present technology can be applied to a content reproduction system.

    Abstract: The present technology relates to an information processing device and method and a program that make it possible to reduce the total number of objects while the influence on the sound quality is suppressed.
    The information processing device includes a pass-through object selection unit configured to acquire data of L objects and select, from the L objects, M pass-through objects whose data is to be outputted as it is, and an object generation unit configured to generate, on the basis of the data of multiple non-pass-through objects that are not the pass-through objects among the L objects, the data of N new objects, N being smaller than (L−M). The present technology can be applied to an information processing device.

    Abstract: The present technology relates to an information processing device and method, and a program capable of reducing a code amount.
    The information processing device includes: an acquisition unit that acquires space information regarding a position and a size of a child space within a parent space and position information in the child space indicating a position of an object within the child space, the child space being included in the parent space, and the object being included in the child space; and a calculation unit that calculates position information in the parent space indicating a position of the object within the parent space on the basis of the space information and the position information in the child space. The present technology can be applied to a signal processing device.
