A receiving apparatus that can be connected to a transmitting apparatus through a plurality of transmission lines includes: a first clock generation section that generates a first clock based on a signal from a first transmission line which is one of the plurality of transmission lines; a first demodulation section that demodulates the signal from the first transmission line based on the timing of the first clock; a second clock generation section that controls the phase of the first clock based on the phase of a signal from a second transmission line which is one of the plurality of transmission lines and is different from the first transmission line to generate a second clock; and a second demodulation section that demodulates a signal from the second transmission line based on the timing of the second clock.

Receiving apparatus and receiving method

A communication device includes a storage unit that stores a predetermined eye mask pattern indicating a receivable range, a receiving unit that receives data from the other communication device, a waveform comparing unit for comparing a waveform of the received data with the eye mask pattern to generate comparison result data and a transmission unit for transmitting the comparison result data to the other communication device.

Communication device and communication system

An information transmission device that is included in components and carries out communication between the components in an information processing device including a control monitoring unit that controls and monitors the components, comprising: a transmission control unit that stores a transmission parameter; a transmission unit that has transmission data input thereto in a first transmission speed or a second transmission speed having a transmission speed lower than the first transmission speed, adjusts the transmission data according to the transmission parameter, and sends the transmission data as a transmission signal to the information transmission device which is a connection destination; a receive control unit that stores a receive parameter; and a receiving unit that adjusts a receive signal received from the information transmission device which is a connection destination in accordance with the receive parameter, and outputs the receive signal in the first transmission speed or the second transmission speed as the receive data.

Information transmission device and information transmission method

A storing part stores image data of an input image signal; and a control part detects a resolution of the image data from a synchronization signal which is in synchronization with the input image signal, and, controls timing of reading the image data from the storing part according to the thus-detected resolution. The control part detects periods of a horizontal synchronization signal and vertical synchronization signal which are in synchronization with the input image signal, determines a magnification for an image to be output, from a horizontal synchronization interval and a vertical synchronization interval of the image to be output, and the periods of the horizontal synchronization signal and vertical synchronization signal which are in synchronization with the input image signal; and controls the timing of reading the image data from said storing part according to the thus-determined magnification.

Image processing device and image processing method

When a power supply activating signal is inputted from an input terminal by depressing a main power supply switch of an electronic apparatus, electric power is supplied from a battery to a protection circuit portion and a management circuit portion through a pack power supply control circuit. Thus, the self discharge of the battery is reduced when a battery pack is not used. The protection circuit portion is operative to output a detection signal to the management circuit portion. Further, the management circuit portion posts a state of the battery to the electronic apparatus. The protection circuit portion is not controlled by the management circuit portion. Thus, even when a bug or a runaway occurs in MCU circuit of the management circuit portion, the battery can be safely protected.
