Description

資料切換矩陣系統 Data switching matrix system

本發明有關於資料切換矩陣系統，特別有關於包含可做為傳送電路或接收電路的可程式傳收電路的資料切換矩陣系統。 The present invention relates to a data switching matrix system, and more particularly to a data switching matrix system including a programmable transmitting and receiving circuit that can be used as a transmitting circuit or a receiving circuit.

資料切換矩陣系統具有多個輸入埠和多個輸出埠，可將多個來源裝置所提供的影音資料輸出到多個目的裝置上。舉例來說，可將宴會場所不同電腦(來源裝置)上的影音資料輸出到電視牆(目的裝置)上。 The data switching matrix system has multiple input ports and multiple output ports, which can output audio-visual data provided by multiple source devices to multiple destination devices. For example, the audio and video data from different computers (source devices) in the banquet venue can be output to the video wall (destination device).

第1圖為繪示了傳統的資料切換矩陣系統100的示意圖。如第1圖所示，資料切換矩陣系統100包含多個輸入埠IP_1,IP_2(僅標示其中兩個)以及多個輸出埠OP_1,OP_2(僅標示其中兩個)。輸入埠IP_1,IP_2用以自來源裝置接收影音資料而輸出埠OP_1,OP_2用以將影音資料輸出到目標裝置。然而，每一個資料切換矩陣系統100的輸入埠和輸出埠的數量是固定的，因此使用者若想使用較多數量的輸入埠或輸出埠，則必須購買更高端的資料切換矩陣系統100。舉例來說，若使用者擁有輸入埠和輸出埠均為16個的資料切換矩陣系統，但卻需要連接20個目標裝置，則使用者需要購買具有更多數量的輸出埠資料切換矩陣系統，其價格通常較為昂貴。如此不僅資料切換矩陣系統的埠在使用上沒有效率，使用者也須花費相當高的成本來購買和維護具不同數量之輸入埠和輸出埠的資料切換矩陣系統。 FIG. 1 is a schematic diagram showing a conventional data switching matrix system 100. As shown in FIG. 1, the data switching matrix system 100 includes a plurality of input ports IP_1, IP_2 (only two of them are marked) and a plurality of output ports OP_1, OP_2 (only two of them are marked). The input ports IP_1, IP_2 are used to receive audiovisual data from the source device and the output ports OP_1, OP_2 are used to output audiovisual data to the target device. However, the number of input ports and output ports of each data switching matrix system 100 is fixed. Therefore, if users want to use a larger number of input ports or output ports, they must purchase a higher-end data switching matrix system 100. For example, if the user has a data switching matrix system with 16 input ports and output ports, but needs to connect 20 target devices, the user needs to purchase a data switching matrix system with a larger number of output ports. The price is usually more expensive. In this way, not only the ports of the data switching matrix system are inefficient in use, but users also have to spend a very high cost to purchase and maintain a data switching matrix system with different numbers of input ports and output ports.

此外，大部份的資料切換矩陣系統無法更動其輸入埠和輸出埠的位置，如此連接來源裝置和目標裝置的連接線可能會彼此交錯而造成使用者的不便。即使輸入埠和輸出埠的位置可以交換，使用者也必須具有一些電腦的知識才可順利完成位置交換的動作，如此對一般使用者也相當不便。 In addition, most data switching matrix systems cannot change the positions of their input ports and output ports, so the cables connecting the source device and the target device may be interleaved with each other, causing inconvenience to the user. Even if the positions of the input port and the output port can be exchanged, the user must have some computer knowledge to successfully complete the position exchange action, which is quite inconvenient for the general user.

因此，本發明一目的為提供一種可更改傳送電路或接收電路之數量或位置的資料切換矩陣系統。 Therefore, an object of the present invention is to provide a data switching matrix system capable of changing the number or position of the transmitting circuit or the receiving circuit.

Therefore, the electric field programmable logic gate array determines whether the programmable transmitting and receiving circuit PTR_1 operates in the first state or the second state according to the written program.

Therefore, the electric field programmable logic gate array can also perform image processing such as image size scaling and compression on the video data.

於一實施例中，一電場可程式化邏輯閘陣列可包含多個可程式傳收電路，也因此電場可程式化邏輯閘陣列可利用寫入的程式對各可程式傳收電路分別設定運行於第一狀態或運行於第二狀態。 In one embodiment, an electric field programmable logic gate array can include a plurality of programmable transmission and reception circuits. Therefore, the electric field programmable logic gate array can use a written program to set each programmable transmission and reception circuit to operate in The first state or the operation in the second state.

此外，可程式傳收電路PTR_1可透過多種方式來設定，在一實施例中，使用者可透過一使用者介面(例如顯示器所顯示的視窗)來設定可程式傳收電路PTR1是運作在第一狀態還是第二狀態。 In addition, the programmable transmitting and receiving circuit PTR_1 can be set in a variety of ways. In one embodiment, the user can set the programmable transmitting and receiving circuit PTR1 to operate in the first through a user interface (such as a window displayed on a display). The state is still the second state.

在另一實施例中，資料切換矩陣系統200可更包含一控制電路203，其依據連接介面CI_1是連接到目的裝置TD_1還是來源裝置SD_1來控制可程式傳收電路PTR_1是運作在第一狀態還是第二狀態。於一實施例中，控制電路203可藉由偵測以辨別連接介面CI_1所連接的是目的裝置TD_1還是來源裝置SD_1，藉此能進一步控制可程式傳收電路PTR_1是運作在第一狀態還是該第二狀態。然而，於一實施例中，判斷連接介面CI_1是連接到目的裝置TD_1還是來源裝置SD_1可以接收的交握訊號或連接訊號來判斷。 In another embodiment, the data switching matrix system 200 may further include a control circuit 203, which controls whether the programmable transmitting/receiving circuit PTR_1 is operating in the first state or not according to whether the connection interface CI_1 is connected to the destination device TD_1 or the source device SD_1. The second state.

The second state. However, in one embodiment, it is determined whether the connection interface CI_1 is connected to the destination device TD_1 or the handshaking signal or connection signal that the source device SD_1 can receive.

如前所述，第2圖實施例中的可程式傳收電路PTR_1不限於只能搭配功能固定的傳送電路TC或接收電路RC，其也可搭配另一個或多個可選擇性做為傳送電路或接收電路的可程式傳收電路。在第3圖的實施例中，資料切換矩陣系 統300除了包含第2圖實施例中的切換矩陣201、可程式傳收電路PTR_1以及連接介面CI_1外，可更包含可程式傳收電路PTR_2以及連接介面CI_2。可程式傳收電路PTR_2連接於切換矩陣201以及連接介面CI_2之間，連接介面CI_2連接於目的裝置TD_2和來源裝置SD_2。於此，可程式傳收電路PTR_2與可程式傳收電路PTR_1雷同，亦可運行於第一狀態或運行於第二狀態而相對應的做為傳送電路或接收電路。 As mentioned above, the programmable transmitting and receiving circuit PTR_1 in the embodiment of FIG. 2 is not limited to only be used with a fixed-function transmitting circuit TC or receiving circuit RC.
