A player model includes an output section that reads out a source packet having a transport packet and arrival time stamp from TS1 and TS2 connected seamlessly to each other and outputs the transport packet according to the arrival time stamp, and a decoder that decodes the transport packet. Two plate-shaped cation-exchange membranes 31 are disposed parallel to each other in a tank body 30, whereby a negative electrode chamber 32 is formed between the cation-exchange membranes 31. The ISI samples are used to limit the search region of possible symbol time offset estimates made using the ISI-free samples. Preferably, the multi-tool also includes an internal socket located in the handle opposite the blade end, where the socket is adapted to removably receive various tool implements.
