摘要： A terminal determines a target value of stream data to be stored in its buffer in relation to its buffer capacity and the transmission capacity of the network. Also, the terminal arbitrarily determines a delay time from when the terminal writes a head data of the stream data to the buffer to when the terminal reads the data to start playback in a range not exceeding a value obtained by dividing the buffer capacity by the transmission capacity. The target value and the delay time are then both notified to a server. Based on those notified values, the server controls the transmission speed so that the buffer occupancy of the terminal changes in the vicinity of the target value without exceeding the target value.

摘要： An optical modulator suppresses a radiation mode of a microwave generated in a connection substrate or termination substrate from entering a signal electrode of the optical modulator and suppresses modulation properties from being degraded. The optical modulator includes an optical modulation element (1) having a substrate with an electro-optic effect, an optical waveguide formed on the substrate, and a modulating electrode (or a signal electrode (2)) for modulating light passing through the optical waveguide; and a connection substrate (4), arranged outside the substrate, for supplying the optical modulation element with a microwave signal operating the optical modulation element. A signal input terminal (22) and a signal output terminal (23) are formed on the connection substrate (20). A recombination suppression unit suppresses a radiation mode (24) of the microwave signal input to the signal input terminal (22) from being recombined with the signal output terminal (23) provided on the connection substrate.
