Abstract: To improve user operability. Provided is a Next change operating section that receives a changing operation on each item in a Next control data set being in a control state of a Next-use M/E of a switcher (vision mixer). When a changing operation is received in the Next change operating section, that is, when there is a changing operation, a control section changes contents of the Next control data set, and in accordance with the changed contents of the Next control data set, sends a control signal concerning the Next-use M/E to the switcher. A user can simply and easily change the contents of the Next control data set by operating the Next change operating section, and operability can be improved.

Abstract: An electronic apparatus is provided. The electronic apparatus is controlled by using parameters relating to a plurality of setting items, including: a specifying unit performing an operation of specifying a setting item out of the plurality of setting items; and a display processing unit displaying a numeric keypad to input a parameter relating to the specified setting item and an initialization icon to initialize the specified setting item on a graphical user interface screen. Further, the electronic apparatus includes: an initial value storing unit storing initial values set/changed regarding the plurality of setting items; and an initialization processing unit returning the parameter of the specified setting item to the initial value based on an operation of the initialization icon.

Abstract: A communication system for a plurality of devices performing communications through a network is provided. The communication system includes a transmitter/receiver, a reception status detector, and a recorder. The transmitter/receiver is included in each of the plurality of devices and configured to alternately transmit a data packet with ID information indicating time to another device and receive the data packet from the device periodically in the plurality of devices. The reception status detector is included in each of the plurality of devices and configured to detect whether the data packet is periodically received based on the ID information added to the data packet received from another device. The recorder is configured to record a result detected by the reception status detector in each of the plurality of devices.
