摘要： Provided are a broadcast transmitting apparatus and a broadcast transmitting method for providing an object-based audio using multi-channel audio encoding and decoding, and a broadcast playback apparatus and a broadcast playback method. The broadcast transmitting apparatus may generate audio identification information for identifying whether a multi-channel audio signal is an object-based audio signal. Then, if the multi-channel audio signal is identified as an object-based audio signal based on the audio identification information, the broadcast playback apparatus may control multi-channel audio signals for each channel and output the signals.

摘要： Disclosed is an integrated voice/audio encoding/decoding apparatus whereby the overlap region of a window is adjusted based on the transition interval. In the present invention, encoding is carried out by making windows of relatively long length overlap in order to increase the efficiency of encoding, while the overlap region of the windows is reduced in accordance with the transition interval when there is a transition interval between frames, thereby making it possible to reduce the occurrence of noise due to transition intervals.
摘要翻译：公开了一种集成的语音/音频编码/解码装置，由此基于转换间隔调整窗口的重叠区域。在本发明中，通过使长度相对较长的窗口相互重叠来进行编码，以提高编码的效率，同时当帧之间存在转换间隔时，根据转换间隔减小窗口的重叠区域，从而可以减少由于过渡间隔引起的噪声的发生。

摘要： Disclosed are a method and a system for converting a multi-channel audio signal. The multi-channel audio signal converting system may comprise: an output position checking unit for checking an output position for each channel of an output multi-channel audio signal and an input multi-channel audio signal; a signal allocation unit which allocates a channel signal of an input channel to an output channel when output positions of the input and output channels are the same in the output and input multi-channel audio signals; a signal distribution unit which distributes the channel signal of the input multi-channel audio signal to two channels of the output multi-channel audio signal which are closest to a channel of the input multi-channel audio signal; and a channel signal calculation unit which calculates a signal for each channel of the output multi-channel audio signal on the basis of channel signals respectively allocated or distributed to channels of the output multi-channel audio signal.
