Abstract: A sound event detection method includes receiving a sound signal and determining and outputting whether a sound event is present in the sound signal by applying a trained neural network to the received sound signal, and performing post-processing of the output to reduce an error in the determination, wherein the neural network is trained to early stop at an optimal epoch based on a different threshold for each of at least one sound event present in a pre-processed sound signal. That is, the sound event detection method may detect an optimal epoch to stop training by applying different characteristics for respective sound events and improve the sound event detection performance based on the optimal epoch.

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.
