Abstract: A broadcast transmitting apparatus and method, and a broadcast playback apparatus and method for providing an object-based audio by encoding and decoding a multichannel audio signal are provided. The broadcast transmitting apparatus may generate audio identification information used to determine whether the multichannel audio signal is an object-based audio signal. When the multichannel audio signal is determined to be the object-based audio signal, based on the audio identification information, the broadcast playback apparatus may control and output the multichannel audio signal for each channel.

Abstract: Provided is an audio signal processing apparatus and method that may convert a speech and audio signal to a spectrogram image, calculate a local gradient using a mask matrix from the spectrogram image, divide the local gradient into blocks of a preset size, generate a weighted histogram for each block, generate an audio feature vector by connecting weighted histograms of the blocks, generate a feature set by performing a discrete cosine transform (DCT) on a feature set of the audio feature vector, and generate an optimized feature set by eliminating an unnecessary region from the transformed feature set and reducing a size of the transformed feature set.
