    摘要： A first initialization pattern signal is a signal in which a maximum signal level and a minimum signal level appear alternately, and a second initialization pattern signal is a signal in which all signal levels appear in a predetermined arrangement. In a ring-shaped network including plural stages of data transmission apparatuses (100), a transmission unit (110) of each data transmission apparatus outputs the first initialization pattern signal successively to a next-stage data transmission apparatus at turn-on of power or immediately after reset, and a reception unit (120) establishes clock synchronization on the basis of the first initialization pattern signal received. When synchronization is established in all of the data transmission apparatuses, the transmission unit (110) outputs the second initialization pattern signal successively to the next-stage data transmission apparatus, and the reception unit (120) sets evaluation levels for the respective signal levels on the basis of the received second initialization pattern signal, and transmission/reception of data is started when evaluation levels are set in all of the data transmission apparatuses.

    摘要： A ring-shaped network quickly performs initialization even when a plurality of data transmission apparatuses are connected thereto. Each data transmission apparatus outputs received data to a device connected thereto while performing establishment of clock synchronization based on the received data, and when synchronization is established, it resends the received data. Further, when synchronization of the connected device is established, it sends data supplied from the connected device. Further, a master data transmission apparatus outputs data at turn-on of power or immediately after reset, and a next-stage slave data transmission apparatus receives the data to establish synchronization, and resends the received data when synchronization is established. Thus, synchronization of all the data transmission apparatuses is established while making a round of this data, and then synchronization of devices connected to the respective data transmission apparatuses is established.

    摘要： A control device determines whether an image generated by merging several concurrently picked-up images has consistent image quality on a display device. If determined No, image quality parameters set in each image pickup device are so controlled as to make the image quality of the merged image consistent. Therefore, the merged image can assuredly have consistent image quality. Further, a signal processing device detects, based on positions of nodes and attributes of cameras, a connection indicating which node is connected to which camera and with what attribute. The signal processing device in advance stores every detectable connection and a plurality of image processing programs corresponding to each connection, and selects and carries out one of the image processing programs corresponding to the detected connection.

    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).
