    摘要： Disclosed is a buffer-based adaptive media playout method in a receiver side of a network media streaming system. The method includes: calculating a playout interval for playing out a current j-th frame (where j is a natural number) of a received media stream; and playing out the current j-th frame after the calculated playout interval has elapsed from the reception of the current j-th frame. The calculation of the playout interval for playing out the current j-th frame of the received media stream includes: calculating a buffer level of a (j+w)-th frame (where w is a natural number); estimating a playout pause or a playout skip on the basis of the calculated buffer level; and calculating the playout interval for playing out the current j-th frame for the predicted one of the playout pause and the playout skip. According to the above-mentioned structure, it is possible to reduce the amount of temporal distortion, such as the RMSE value of playout discontinuity due to delay or jitter, as compared to the buffer-threshold-based media playout techniques according to the related art.

    摘要： At least one of a hollow particle 14, a porous particle 24, and a solid particle 34 having the pores 18, 28, 38 on the surface thereof is subjected to plasma irradiation under a reduced pressure while changing plasma irradiation intensity and/or the degree of vacuum. After the plasma irradiation, at least one type of monomer is graft polymerized onto the surface of the plasma irradiated particle by contact between the at least one type of monomer and the particle so as to substantially fill the pores 18, 28, and 38 of the particle with grafted polymers 12 of the monomers.
