    摘要: Provided is a transport packet generating apparatus that generates a transport packet having a variable length, and the length of the transport packet is indicated by a field included in a header of the transport packet or a synchronization area of the transport packet, in the field indicating a length of the transport packet. A transport depacketizing apparatus depacketizes the transport packet by decoding the field or detecting a starting point of the transport packet based on a predetermined rule with respect to the synchronization area to decode the transport packet.

    摘要: Provided are an apparatus and method of separating, from a mixed signal, a sound source generated using a rhythm musical instrument based on characteristics of the rhythm musical instrument repeated in an aspect of time. The apparatus may include a separation unit to separate a plurality of mixed signals into a plurality of segments, a Nonnegative Matrix Partial Co-Factorization (NMPCF) analysis unit to perform an NMPCF analysis on the plurality of segments, and to obtain a plurality of entity matrices based on the analysis result, a target instrument signal separating unit to separate, from the mixed signals, a target instrument signal, by calculating an inner product between the plurality of entity matrices, and a signal association unit to associate the target instrument signals separated from each of the plurality of segments.
