A multiplexing unit on the transmitting side estimates information amounts supplied from respective signal processing units, determines a multiplex code on the basis of respective information amounts, derives a parity of the first determined multiplex code to form a second multiplex code, adds a CRC to each of the multiplex codes to generate two headers H1 and H2, takes out information data of respective media according to the multiplex codes, incorporates the information data into a packet together with the two headers H1 and H2, and outputs the packet. If error correction of H1 is impossible on the receiving side, error correction decoding is conducted by using the header H2. If error correction of H2 is also impossible, error correction decoding is conducted collectively for H1 and H2.

Via real time online bandwidth measurement, this method confirms the threshold value ssthresh. When the congestion window (CW) is less than a half of the threshold, the rule of exponent gain is followed. Otherwise CW gains each time a value of a half of difference of the threshold and CW (ssthresh-cwnd) to approach gradually the threshold. Until the difference is less than the regulation factor phi (ssthresh/2>= phi >=2). Then CW is set as the threshold value to enter the stage of avoiding congestion. This invention can reduce the happening of loss of several texts in a window at the slowly start stage, reduce the package loss rate and raise the net transferring ability.

A method of mounting conductive balls comprises a step of setting, on a substrate, a mask that includes a plurality of apertures for disposing conductive balls on the substrate and a filling step. The filling step includes using a head that moves along a surface of the mask, holding a group of conductive balls in an area that is part of the surface of the mask, and moving the area so that parts of a path taken by the area overlap. By limiting the area where filling is carried out and moving the conductive balls while gathering the conductive balls in this area, it is possible to prevent losses for the conductive balls, to increase the filling efficiency, and to suppress the number of unfilled apertures.
