Abstract

A data transmission device and a data transmission system that can share data generated based on data received from each terminal, and update the shared data in the operation of the system are provided. The data transmission device sends and receives a packet to and from the terminal connected thereto via a communication network and the packet includes a first slot in which individual output data to be output from the terminal is stored and a second slot in which input data to be input to the terminal is stored. The data transmission device includes a sending part that sends the packet to the terminal, a receiving part that receives the packet sent to the terminal, and a controller that generates the input data based on output data including the individual output data stored in the first slot and stores the input data in the second slot.

Claims21

Dependent claims

A data transmission device for sending and receiving a packet to and from at least one terminal connected thereto via a communication network, the packet including:

a first slot in which individual output data, which is a sound signal, to be output from the terminal is stored;
and concurrent with the first slot a second slot in which input data to be input to the terminal is stored,
the data transmission device comprising:
a primary sound signal output device configured to generate the sound signal based on an input sound and to output the sound signal;
a transmitter configured to send the packet to the terminal;
a receiver configured to receive the packet sent to the terminal;
and
a controller configured to generate the input data based on output data including the individual output data stored in the first slot and stores the input data in the second slot, wherein
the sound signal output from the primary sound signal output device is stored in the first slot as the individual output data,
the input data is a sum signal of the sound signal output from the primary sound signal output device and the sound signal output from the terminal and functions as control information for controlling operation of the terminal, and
the terminal performs predetermined signal processing based on the control information.

A data transmission system comprising:

a primary terminal;
and
at least one secondary terminal connected to the primary terminal via a communication network, wherein
the primary terminal is configured to send and to receive a packet to and from the secondary terminal, wherein
the packet includes, concurrently:
a first slot in which individual output data, which is a sound signal, to be output from each of the primary terminal and the secondary terminal is stored, and
a second slot in which input data to be input to the primary terminal and the secondary terminal is stored,
the primary terminal is further configured to generate the input data based on output data including the individual output data, and to store the input data in the second slot,
when the secondary terminal receives the packet that has the input data stored in the second slot, the input data is input to the secondary terminal having received the packet, wherein
the input data is a sum signal of the sound signal output from the primary terminal and the sound signal output from the secondary terminal, and functions as control information for controlling operation of each of the primary terminal and the secondary terminal, and
the primary terminal and the secondary terminal perform predetermined signal processing based on the control information.
