    Abstract: Disclosed herein are a signal-multiplexing apparatus and method based on machine learning. The signal-multiplexing method based on machine learning, performed by a signal-multiplexing apparatus based on machine learning, including training a transmitted signal using a machine-learning technique, performing complex mapping to transmit the transmitted signal as multiple signals, receiving the multiple signals and regularizing the multiple signals based on a preset rule corresponding to the machine-learning technique, outputting an estimated value for the transmitted signal by training regularized multiple signals using the machine-learning technique, calculating a difference between the transmitted signal and the estimated value for the transmitted signal, and detecting the transmitted signal from an output value when the difference is less than or equal to a preset value.

    Abstract: Disclosed herein are a hybrid download method and apparatus for multiview streaming. The hybrid download method includes requesting a group download for an n−1-th segment from a server, playing an n−3-th segment at a viewpoint VP1 of a viewer, when a group download request for the n−1-th segment is completed, making a group download request for an n-th segment, when a change in a viewpoint of the viewer occurs at a time at which an n−2-th segment is played, playing a low-quality n−2-th segment at a viewpoint VP3, when the group download for the n-th segment is completed, requesting a single download for a high-quality n−1-th segment corresponding to the viewpoint VP3 from the server, and when the single download for the high-quality n−1-th segment corresponding to the viewpoint VP3 is completed, playing the high-quality n−1-th segment at the viewpoint VP3.

    Abstract: Disclosed herein are an apparatus and method for removing a self-interference signal. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives an upstream signal for removing self-interference, generates a downstream signal for channel estimation, replicates a self-interference signal in a time domain and a self-interference signal in a frequency domain using the upstream signal and the downstream signal, and removes the self-interference signal from the upstream signal using the replicated self-interference signal in the time domain and the replicated self-interference signal in the frequency domain.

    Abstract: Disclosed herein are an apparatus and method for providing a broadcasting service. The method for providing a broadcasting service is performed using a broadcasting service provision apparatus and a terminal device, and includes performing, by the broadcasting service provision apparatus and the terminal device, initialization using information acquired from a downstream signal received from a Cable Modem Termination System (CMTS), converting, by the terminal device, an upstream signal received from a Cable Modem (CM) into a digital signal, encapsulating the digital signal into an IP packet, and transmitting the IP packet to the broadcasting service provision apparatus, and extracting, by the broadcasting service provision apparatus, the digital signal from the IP packet received from the terminal device, converting the digital signal into an analog signal, and transmitting an upstream signal corresponding to the analog signal to the CMTS.
