摘要： A master station 11 produces a token packet for isochronous data in which a slave station 12 and slave stations 13 and 14 serving as a sending station and receiving stations are designated using IDs for isochronous data “#2” and “#3” in accordance with contents described in a table 161 held in its inner part so as to manage a transmission bandwidth using a token packet sending/analysis executing device 16, and sends out the produced token packet to a transition path 15 on the downstream side. The slave station 12 sends out an isochronous data packet 42 using the token packet for isochronous data 41. According to the token packet for isochronous data 41, the slave stations 13 and 14 are designated as receiving stations using the ID for isochronous data “#3”, so that the slave stations 13 and 14 perform the above-mentioned operations, to receive the isochronous data packet 42. The sending station can thus transmit the same isochronous data to a plurality of receiving stations belonging to a broadcast group, so that it is possible to establish multicast communication (communication to a plurality of nodes).

摘要： In a filter circuit (1), a common mode choke (2) and a normal mode choke (3) have extremely high and low impedances, respectively, for common mode signals received through two input terminals (1a and 1b). The chokes have the opposite impedance characteristics for differential signals. In particular, the difference in impedance is large. Furthermore, the normal mode choke (3) is installed as a previous stage of the common mode choke (2). Accordingly, common mode noises which enter the two input terminals (1a and 1b) penetrate the normal mode choke (3), but neither penetrate the common mode choke (2) nor are reflected from the common mode choke (2). In particular, common mode currents flow through the normal mode choke (3) but do not flow through the common mode choke (2).
摘要翻译：在滤波器电路（1）中，对于通过两个输入端子（1a和1b）接收的共模信号，共模扼流圈（2）和正常模式扼流圈（3）分别具有极高和低阻抗。扼流圈对差分信号具有相反的阻抗特性。特别地，阻抗的差异很大。此外，正常模式扼流圈（3）安装为共模扼流圈（2）的前一级。因此，进入两个输入端子（1a和1b）的共模噪声穿透正常模式扼流圈（3），但都不穿透共模扼流圈（2），也不会从共模扼流圈（2）反射。特别地，共模电流流过正常模式扼流圈（3），但不流过共模扼流圈（2）。

摘要： In a physical layer of each data transmission apparatus 1, a physical layer initialization process is performed in response to a reset exit process performed by the irrespective CPUs 4. Then, in a link layer of a master data transmission apparatus 1 and in a link layer of a data transmission apparatus 1 which operates in a normal mode, after the completion of the physical layer initialization process, a link layer initialization process is performed in response to a reset exit process performed by their respective CPUs 4, and then the data transmission apparatuses 1 start data communication using their respective physical layers and link layers. On the other hand, a link layer of a data transmission apparatus 1 which operates in a bypass mode maintains its reset state, and the data transmission apparatus 1 transmits data using only its own physical layer by bypassing its own link layer.

摘要： In a network of a topology of a loop and a bus, occurrence of a failure is detected and a location of the failure is specified. Occurrence of the failure is detected by detecting that a specific signal pattern to be received at regular time intervals within a fixed time period is not received. A node which has detected occurrence of the failure transmits or receives a specifying signal among the nodes, and decide whether or not the failure has occurred adjacently to itself. A packet indicating a decided location of the failure is transmitted or received among nodes, and thereby respective nodes specify the location of the failure. When the failure has occurred at the master node, a node having a smallest node ID after waiting time according to the node ID operates as the alternative master node.

摘要： A network system comprises a main loop in which one master node which issues a token packet for data communication, and at least one slave node are connected in a loop; a first sub loop in which the master node, one sub-master node, and at least one slave node are connected in a loop; and at least one second sub loop in which the master node, at least two sub-master nodes including the sub-master node of the first sub loop, and at least one slave node are connected in a loop. In this network system, each node has an analysis execution unit which performs analysis of the token packet, control of data transmission and data reception, and a switch for changing the connection. When each node receives and analyzes the token packet, it controls the switch so as to output, transmit, or discard the token packet and a data packet. Therefore, addition of nodes and loops is facilitated while maintaining the transmission efficiency, without increasing the packet transmission time.

摘要： The object is to provide a video signal processing apparatus capable of minimizing overtaking of fields of a video signal and continuous display of the video signal of the same field and reducing degradation in image quality of the output video signal. The apparatus has a field signal holding section 9 which holds the value of an input field signal and outputs the held value as a held value signal and a readout determination section 10 which determines the video signal of the field to be read out, and which outputs the determined signal as a readout field signal. The field signal holding section 9 holds the value of the input field signal a plurality of times with every occurrence of the readout field signal period, and outputs a held value signal constituted of the plurality of values of the input field signal held. The readout determination section 10 determines the video signal of the field to be read out from a frame memory 4 on the basis of the value of the held value signal in the current readout field period and the value of the held value signal in the immediately preceding readout field period.
