Abstract: An audio metadata providing apparatus and method and a multichannel audio data playback apparatus and method to support a dynamic format conversion are provided. Dynamic format conversion information may include information about a plurality of format conversion schemes that are used to convert a first format set by a writer of multichannel audio data into a second format that is based on a playback environment of the multichannel audio data and that are set for each of playback periods of the multichannel audio data. The audio metadata providing apparatus may provide audio metadata including the dynamic format conversion information. The multichannel audio data playback apparatus may identify the dynamic format conversion information from the audio metadata, may convert the first format of the multichannel audio data into the second format based on the identified dynamic format conversion information, and may play back the multichannel audio data with the second format.

Abstract: A signal compression method and apparatus and a signal restoration method and apparatus are provided. The signal compression method includes outputting an input signal, obtained by processing an audio signal, which is input, based on a human auditory perception characteristic, using an auditory perception model, extracting a feature vector from the input signal using a feature extraction module, and outputting a code obtained by compressing the feature vector using a trained signal compression model.

Abstract: Disclosed is an operation method of a communication node in a communication network. The operation method of the communication node having divided functions of a base station in a communication network may comprise generating digital pulse signals based on a high-speed clock synthesis for a time synchronization signal used for a synchronization operation of the communication node; performing counting on the digital pulse signals based on a notification setting value obtained in advance for controlling the synchronization operation of the communication node; generating a pulse signal corresponding to the notification configured value based on a result of the counting; and performing a function of the communication node, which is divided according to supporting functions of the base station, by performing an operation indicated by the generated pulse signal.
