Abstract: Provided is a method for controlling synchronizing downmix signals and MPEG surround side information signals by controlling a delay according to the kind of downmix audio signals in an MPEG surround decoder. When multi-channel audio signals are restored using an HE-AAC decoder and a low-power MPEG surround decoder and complex QMF signals outputted from the HE-AAC decoder are used as downmix signals, a delay unit compensates for a delay caused in a real-to-complex converter. Anther delay unit delays spatial parameters to compensate for a delay caused in QMF and Nyquist banks when time-domain downmix signals are used. Also, when multi-channel audio signals are restored using an HE-AAC decoder and a high-quality MPEG surround decoder and complex QMF signals outputted from the HE-AAC decoder are used as downmix signals, a delay unit compensates for a delay caused in a real-to-complex converter.

Abstract: Provided is a random backoff apparatus and method for receiving augmented content that may prevent a delay or a down of a server caused by a plurality of receiving terminals accessing a server simultaneously, when a digital broadcasting system provides broadcast-based bidirectional broadcasting services over a communication network. That is, a technology for distributing receiving terminals accessing a server to receive augmented content, or accessing a home page of a corresponding program, based on metadata transferred from the digital broadcasting system to a broadcasting network. In a bidirectional digital method, a number of requests for access to the home page or the augmented content related to the program may be received from receiving terminals at one time. Accordingly, there is a desire for a method of preventing collision caused when a plurality of stations simultaneously access a single wireless channel.
