This application claims the benefit of Korean Patent Application No. 10-2011-0075621, filed on Jul. 29, 2011 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The present invention relates to a system for controlling sounds and images through a three-dimensional matrix circuit, and more particularly, to a system for controlling sounds and images through a three-dimensional matrix circuit, which allows a user to easily control a connection between an amplifier and a speaker and a connection between an image transmission device and a display device by a multicast method in a Graphic User Interface (GUI) environment using the matrix circuit.
Generally, broadcast or sound systems using amplifiers and speakers include one or more speakers to deliver messages to people at their places of a building having a plurality of divided spaces, such as schools, large buildings, and plants.
In order to implement such a sound system, an amplifier and a sound generator (e.g., microphone and audio) for supplying sound signals of an appropriate size through a plurality of speakers are installed, and the plurality of speakers installed at each place are connected to a controller.
The controller of the speaker includes a plurality of input channels and a plurality of output channels, and controls sound signals inputted into the input channels to be transmitted to the speakers through the output channels. In other words, the controller may transmit sounds signals inputted from the input channels such as microphone, DVD player, and audio to all speakers or some speakers.
Also, image equipment such as DVD players or Blueray disc players transmits images to TVs installed at each place inside a building. TVs installed at each place may perform transmission to all channels or an individual channel through a separate control function.
Since interconnections between the input channels and the output channels are manually made by a user, the controller of the speakers is difficult to change or modify the interconnection of the input channels and the output channels.
In order to overcome the above limitation, a matrix circuit has been developed to select a portion of the plurality of amplifiers and speakers necessary for the broadcasting in a typical sound system and connect the portion of the plurality of amplifiers and speakers to a sound source.
A M×N type of matrix circuit allows M amplifiers and N speakers to be connected to each other. A user can control a switch that can select the input or output of the matrix circuit through manual input or Graphical User Interface (GUI) environment to set or control the connection of the amplifiers and the speakers that are necessary.
However, although using this matrix circuit, a user needs to specify the types of the necessary amplifiers and speakers and calculate the number of the necessary amplifiers and speakers in consideration of the output of each amplifier according to the type of the sound source and a desired output group to control the switch of the matrix circuit.
Also, since the sound system of controlling the speakers and amplifiers using the matrix circuit is implemented in a flat type, there is no expandability, and the input and output are fixed, making a variable design of hardware according to the field situation impossible.
As shown in
Accordingly, in order to efficiently control a plurality of speakers and amplifiers installed in divided spaces inside a building that gradually increases in its size, the variable design of hardware according to the field situation is essential, and the input and output of the matrix circuit need to be more variously utilized so as to organically change the connection between the amplifiers and the speakers.
The present invention provides a system for controlling sounds and images through a three-dimensional matrix circuit, which can conveniently and quickly perform a change or modification upon interconnection between amplifiers and speakers and connection of video and audio signals of various image transmission devices to a display device through a plurality of channels due to changeable input and output by manufacturing for the slot-shaped and enables the variable design of hardware according to the field situation.
In accordance with an aspect of the present invention, there is provided a system for controlling sounds and images through three-dimensional matrix circuit, which outputs voice or sound signals outputted from a sound generator and amplified by a plurality of amplifiers through a plurality of speakers, the system comprising: a matrix circuit configured in a three-dimensional type such that the amplifiers and the speakers to which the voice or sound signals outputted from the sound generator are delivered are connected to each other, changing and adding input/output according to a user's selection; a controller for controlling various kinds of operations of the speakers and the amplifiers by allowing a user to control the matrix circuit by a multicast method so as to select amplifiers or a combination thereof to be used for broadcasting using a keyboard or a mouse.
In accordance with another aspect of the present invention, there is provided a system for controlling sounds and images through three-dimensional matrix circuit, which outputs image and sound signals outputted from a plurality of image transmission devices through a plurality display devices, the system comprising: a matrix circuit three-dimensionally implementing a connection between the display devices to which the image and sound signals outputted from the image transmission device are delivered and changing and adding input/output according to a user's selection; a controller for controlling operations of the system by allowing a user to control the matrix circuit by a multicast method so as to select a combination of the image transmission devices and the display devices to be used for broadcasting using a keyboard or a mouse.
The system for controlling sounds and images through three-dimensional matrix circuit may include: a power supply for supplying power to the system; a communication unit taking charge of duplex communication with an external device; a plurality of expansion slots taking charge of input/output connection according to a field situation; a main board mounted with various kinds of parts comprising the matrix circuit, the controller, the power supply, and the communication unit and enabling an interconnection and communication of the expansion slots.
The matrix circuit may be manufactured into a slot type, and the plurality of expansion slots taking charge of input/output connection according to a field situation may be mounted with an expansion board, in which a size of the matrix circuit increases or decreases according to a user's selection.
The communication unit taking charge of duplex communication with an external device may check whether or not there is an abnormality of the controller comprising the matrix circuit by performing duplex communication with a personal computer.
Accordingly, a system for controlling sounds and images through a three-dimensional matrix circuit according to an embodiment of the present invention can conveniently and quickly perform a change or modification of interconnection between amplifiers and speakers and connection of video and audio signals of various image transmission devices to a display device through a plurality of channels by including the matrix circuit, can expand the output from any terminal according to the field situation, and can significantly reduce the number of parts by implementing a typical flat matrix circuit into the three-dimensional matrix circuit.
Also, the system for controlling sounds and images through the three-dimensional matrix circuit can more variously utilize the input and the output so as to organically change the connection between the amplifiers and the speakers and the connection between the image transmission device and the display device. Furthermore, the system can be efficiently managed in a Graphical User Interface (GUI) environment, and can also be remotely controlled and managed through Internet connection.
