Data transmitting method and device for transmitting stream data

Abstract

In the present invention, in transmitting stream data successively reproduced in point of time to a recording unit connected to network through the network, there is employed an approach to detect that synchronous recording has been designated from input means to transmit mute data generated from mute data generating means to a recording unit through the network for a time period during which data that data holding means in which held content is changed from the recording unit through the network holds has a first predetermined value. On the other hand, in the case where it is detected that data that the data holding means holds indicates a second predetermined value, inputted stream data is transmitted to the recording unit through the network. Thus, the recording unit is permitted to carry out recording in the state where sound is not interrupted, and is permitted to execute data recording in which operating time of mechanical parts required so that operating state of the recording unit shifts to recording state, and/or response relating to control with respect to the recording unit are taken into consideration.
