摘要:
An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.

According to one embodiment, a circuit board includes a board main body, an electrode, a circuit plate and a connector. The board main body includes a first surface, a second surface located opposite to the first surface, a first side edge that extends between the first surface and the second surface, and a second side edge that extends between the first surface and the second surface and intersects the first side edge. The second side edge is provided with a fitting part. The electrode is provided on the first surface. The circuit plate is soldered to the electrode and has flexibility. The connector is attached to the board main body. A cable is inserted into the connector in a direction perpendicular to the first side edge.

An alarm system and an alarm device that are capable of enhancing a fail-safe function. A fire alarm device (A) operating as a master unit transmits a switching request signal to fire alarm devices operating as slave units at a predetermined timing. The switching request signal contains at least an own address and an address of a fire alarm device (B) that is to operate as the master unit next (S20). Upon reception of the switching request signal, among the fire alarm devices operating as the slave units, the fire alarm device (B) that is to operate as the master unit next judges whether or not switching is possible based on switching availability judgment information for judging whether or not switching to the master unit is possible (S30), and, when it is judged that switching is possible, starts operating as the master unit (S31).

摘要:
In an FED (Field Emission Display), lowering of a color temperature is suppressed which is caused by that light emission luminance of respective color phosphors is different from each other so as to achieve a better white balance. A display apparatus is equipped with a cathode substrate containing a plurality of electron emitter elements, and an anode substrate. The anode substrate is arranged opposite to the cathode substrate, and contains three colors of red, green, blue phosphors which are excited by electrons emitted from the electron emitter elements so as to emit light. Then, an area of either the red phosphor or an area of the blue phosphor is made smaller than an area of the green phosphor.
