Description
Technical Field
The present invention relates to data cross-point matrix systems, and more particularly to data cross-point matrix systems that include programmable transmit and receive circuitry that can be either transmit or receive circuitry.
Background
The data cross-point matrix system is provided with a plurality of input terminals and a plurality of output terminals, and can output video and audio data provided by a plurality of source devices to a plurality of destination devices. For example, video and audio data from different computers (sources) at the banquet site can be output to the video wall (destination device).
Fig. 1 is a schematic diagram illustrating a conventional data cross-point matrix system 100. As shown in fig. 1, the data cross-point matrix system 100 includes a plurality of input terminals ip_1, ip_2 (only two of which are indicated) and a plurality of output terminals op_1, op_2 (only two of which are indicated). The input terminals ip_1 and ip_2 are used for receiving audio-visual data from a source device and the output terminals op_1 and op_2 are used for outputting the audio-visual data to a target device. However, the number of input terminals and output terminals of each data cross-point matrix system 100 is fixed, so that a user must purchase a higher-end data cross-point matrix system 100 if he wants to use a larger number of input terminals or output terminals. For example, if a user has a data cross-point matrix system with 16 input terminals and 16 output terminals, but needs to connect 20 target devices, the user needs to purchase a data cross-point matrix system with a greater number of output terminals, which is typically more expensive. Not only is the terminals of the data cross-point matrix system not efficient in use, but the user also has to spend a significant amount of cost purchasing and maintaining data cross-point matrix systems having different numbers of input and output terminals.
In addition, most data cross-point matrix systems cannot change the positions of their input terminals and output terminals, and thus the connection lines connecting the source device and the target device may be staggered with each other, which may cause inconvenience to the user. Even if the positions of the input terminal and the output terminal can be exchanged, the user must have knowledge of some computer to smoothly complete the position exchange, which is quite inconvenient for the general user.

Wherein the first input data and the second input data are one or a combination of video data and audio data. The cross point matrix is arranged on a first circuit board, the first programmable transmitting and receiving circuit and the first connecting interface are arranged on a second circuit board, and a user can insert the second circuit board into the first circuit board or remove the first circuit board.

Fig. 2 to 6 are schematic diagrams illustrating a data cross-point matrix system according to various embodiments of the present invention. In the following description, "connected" may mean directly connected or indirectly connected. In the embodiment of fig. 2, the data cross-point matrix system 200 comprises: a cross-point matrix (cross point matrix) 201, programmable transmit receive circuitry ptr_1 and a connection interface ci_1. The programmable transmit-receive circuit ptr_1 is connected between the cross-point matrix 201 and the connection interface ci_1. The programmable transceiver ptr_1 can be selectively operated in different states and correspondingly used as a transmitting circuit or a receiving circuit, and the connection interface ci_1 can correspondingly use the programmable transceiver ptr_1 as a transmitting circuit or a receiving circuit to be used as a transmitting interface or a receiving interface. In the embodiment of fig. 2, the programmable transceiver ptr_1 is a matched function of the transmitting circuit TC and the receiving circuit RC. However, in other embodiments, the programmable transceiver circuit ptr_1 may be combined with other programmable transceiver circuits that may be selectively used as either the transmitter circuit or the receiver circuit.
In one embodiment, the cross-point matrix 201 may include a plurality of multiplexers to provide different data paths. The programmable transmit-receive circuit ptr_1 functions as a receive circuit in a first state to transmit data from the source device sd_1 to the destination device td_2 through the connection interface ci_1, the cross-point matrix 201, the transmit circuit TC, and the connection interface ci_a, and functions as a transmit circuit in a second state to transmit data from the source device sd_2 to the destination device td_1 through the connection interface ci_b, the receive circuit RC, and the connection interface ci_1.
IN detail, the programmable transmit-receive circuit ptr_1 is used as a receiving circuit capable of receiving the input data in_1 and transmitting the input data in_1 to the cross-point matrix 201 IN the first state. The programmable transmit-receive circuit ptr_1, IN the second state, is a transmit circuit that is capable of receiving the second input data in_2 from the cross-point matrix 201 and transmitting the second input data in_2. That is, in the first state, the programmable transmit-receive circuit ptr_1 and the connection interface ci_1 are used as input terminals, and in the second state, the programmable transmit-receive circuit ptr_1 and the connection interface ci_1 are used as transmission terminals.
The connection interface ci_1 is a reception interface of the connection source device sd_1 in the first state, and is a transmission interface of the connection destination device td_1 in the second state. The source device sd_1 provides the input data in_1, and the destination device td_1 receives the input data in_2.
The input data in_1 and the input data in_2 may be one of video data and audio data or a combination thereof, but the present invention is not limited to these examples.

The transfer circuit TC is connected between the connection interface ci_a and the cross-point matrix 201. The receiving circuit RC is connected between the connection interface ci_b and the cross-point matrix 201. IN this embodiment, the transmitting circuit TC and the receiving circuit RC are circuits with fixed functions, and the transmitting circuit TC is only used for transmitting data, that is, the transmitting circuit TC can receive the input data in_1 from the cross point matrix 201 and transmit the input data in_1 to the connection interface ci_a. The connection interface ci_a is used to transmit the input data in_1 to the destination device td_2. The receiving circuit RC is only used for receiving data, i.e. the receiving circuit RC is capable of receiving the input data in_2 from the connection interface ci_b and transmitting the input data in_2 to the cross-point matrix 201. Here, the connection interface ci_b is used for receiving the input data in_2 from the source device sd_2.
In one embodiment, the programmable transmit receive circuit PTR_1 is included in a field programmable gate array (Field Programmable Gate Array, FPGA) that can be operated in either a first state or a second state depending on the program being written. Therefore, the field programmable gate array determines whether the programmable transmit/receive circuit ptr_1 is operating in the first state or the second state according to the written program.
IN addition, IN one embodiment, the input data in_1 and the input data in_2 may be video data, so the field programmable gate array may further perform image processing such as image size scaling (scale), compression, and the like on the video data.
In one embodiment, a field programmable gate array may include a plurality of programmable transceiving circuits, and thus the field programmable gate array may set each programmable transceiving circuit to operate in a first state or in a second state, respectively, using a written program.
In addition, the programmable transmit receive circuit PTR_1 may be set in a variety of ways, and in one embodiment, a user may set whether the programmable transmit receive circuit PTR1 is operating in the first state or the second state via a user interface (e.g., a window displayed by a display).
In another embodiment, the data cross-point matrix system 200 may further include a control circuit 203 that controls whether the programmable transmit-receive circuit ptr_1 operates in the first state or the second state according to whether the connection interface ci_1 is connected to the destination device td_1 or the source device sd_1. In one embodiment, the control circuit 203 can further control whether the programmable transceiver circuit ptr_1 is operated in the first state or the second state by detecting to identify whether the destination device td_1 or the source device sd_1 is connected to the connection interface ci_1. However, in an embodiment, the connection interface ci_1 is determined whether to connect to the destination device td_1 or the source device sd_1 can receive a handshake signal or a connection signal.
As described above, the programmable transceiver ptr_1 in the embodiment of fig. 2 is not limited to the one with fixed function of the transmitting circuit TC or the receiving circuit RC, but can also be matched with one or more other programmable transceivers that can be selectively used as the transmitting circuit or the receiving circuit. In the embodiment of fig. 3, the data cross-point matrix system 300 may further include a programmable transmit-receive circuit ptr_2 and a connection interface ci_2 in addition to the cross-point matrix 201, the programmable transmit-receive circuit ptr_1 and the connection interface ci_1 in the embodiment of fig. 2. The programmable transmit-receive circuit ptr_2 is connected between the cross point matrix 201 and the connection interface ci_2, and the connection interface ci_2 is connected to the destination device td_2 and the source device sd_2. Here, the programmable transmit/receive circuit ptr_2 and the programmable transmit/receive circuit ptr_1 may be operated in the first state or in the second state, respectively, as a transmit circuit or a receive circuit.
IN the embodiment of fig. 3, IN the first state, the input data in_1 from the source device sd_1 is transmitted to the destination device td_2 via the connection interface ci_1, the programmable transmit-receive circuit ptr_1, the cross point matrix 210, the programmable transmit-receive circuit ptr_2, and the connection interface ci_2. IN the second state, the input data in_2 from the source device sd_2 is transmitted to the destination device td_1 via the connection interface ci_2, the programmable transmit receive circuit ptr_2, the cross point matrix 210, the programmable transmit receive circuit ptr_1, and the connection interface ci_1. The operation of the programmable transceiver circuit ptr_1 in fig. 2 is the same as that of the programmable transceiver circuit ptr_1 in fig. 1, and thus will not be described here again.
The programmable transmit/receive circuit ptr_2 is IN the first state as a transmit circuit that receives the input data in_1 from the cross-point matrix 201 and transmits the input data in_1 to the connection interface ci_2, which then transmits the input data in_1 to the destination device rd_2. Similarly, the programmable transmit receive circuit ptr_2 IN the second state is a receive circuit that is capable of receiving input data in_2 from the connection interface ci_2 and transmitting the input data in_2 to the cross-point matrix 201. In one embodiment, the connection interface ci_2 is connected to the programmable transceiver circuit ptr_2, the connection interface ci_2 is used as a receiving interface for the connectable destination device td_2 in the first state, and the connection interface ci_2 is used as a transmitting interface for the connectable source device sd_2 in the second state. IN this embodiment, the source device sd_2 provides the input data in_2, and the destination device td_2 receives the input data in_1.

That is, the number of receiving circuits or transmitting circuits of the data cross-point matrix system is not fixed.
