Abstract:
1. An automix system comprising: a plurality of equipments connected to each other through a network, said plurality of equipments including an audio equipment and a control equipment capable of recording event data for automated mixing of audio signals, wherein one of said plurality of the equipments use its own time counter to count time and repeatedly transmit, to the network in a periodic cycle of predetermined intervals, first time information representative of the counted time and the others of said plurality of equipments each use its own time counter for counting time, receive the first time information through the network, and correct the counted time based on the received first time information, thereby synchronizing the time counted by the time counter of the one equipment with the time counted by the time counters of the others of said plurality of equipments, wherein the audio equipment comprises: an operation device that is operable by an user to provide event data indicative of an operation; an extensive time counter that counts overflow of the time counter of the audio equipment to provide an extensive time of the audio equipment, wherein the time counted by the time counter of the audio equipment and the extensive time provided by the extensive time counter of the audio equipment constitute an extended time in the audio equipment; a time stamp section that acquires, from the time counter of the audio equipment and the extensive time counter of the audio equipment, an extended time at which the event data is provided by said operating device, and affixes the acquired extended time to the event data as a time stamp; and a transmitter that transmits the event data together with the time stamp to the control equipment via the network, and wherein the control equipment comprises: a receiver that receives the event data together with the time stamp via the network; an extensive time counter that counts overflow of the time counter of the control equipment to provide an extensive time of the control equipment, wherein the time counted by the time counter of the control equipment and the extensive time provided by the extensive time counter of the control equipment constitute an extended time in the control equipment; a recording section that records the received event data together with the time stamp, and wherein one of the control equipment and the audio equipment transmits, to the network at a specified timing, second time information indicative of the extended time of the one of the control equipment and the audio equipment, and the other of the control equipment and the audio equipment receives the second time information and, based on the received second time information, synchronizes the extended time of the other of the control equipment and the audio equipment with the extended time of the one of the control equipment and the audio equipment.
