A data transfer device includes: a video transmission circuit, transmitting video data from a first deviceto a second deviceduring a video period as a timing of transmitting the video data; a transmission part, transmitting non-video data between the first deviceand the second deviceduring a video blanking period as a timing of transmitting the non-video data; and a monitoring part, during the video blanking period, controlling the transmission partto stop transmission of the non-video data from the second deviceto the first devicein response to presence of a signal from the first deviceand stop transmission of the non-video data from the first deviceto the second devicein response to presence of a signal from the second device

Data transmission device and data transmission method

A video signal processing device includes: a video signal dividing unit configured to divide a video signal into first to k-th (k is an integer of 2 or greater) partial video signals for each frame; a video change detection unit configured to determine, for each of the first to k-th partial video signals, whether or not a video based on the partial video signals has changed between respective frames, and generate first to k-th video change detection signals representing the respective detection results; and a video sameness determination unit configured to generate a video sameness signal indicating that the video signal has not changed, if the number of video change detection signals that indicate the video has not changed, among the first to k-th video change detection signals, is greater than a prescribed number.

Video signal processing device, video freeze detection circuit and video freeze detection method

A video signal processing device including a video signal dividing unit that divides a video signal into first to k-th division video signals (k is an integer of 2 or more) for each frame; a video change detecting unit that detects, for each of the first to k-th division video signals, whether or not there has occurred a change in the video signal between the frames, and generates first to k-th video change detection signals representing the detection results; and a video no-change determining unit that generates a video no-change signal indicating that there is no change in the video signal when the number of video change detection signals indicating that there is no change among the first to k-th video change detection signals is greater than a predetermined number.

Video signal processing device, video freeze detecting circuit and method of detecting video freeze

A transmission apparatus includes: a data frame sequence generation part that generates a data frame sequence; a synchronization frame generation part that generates a synchronization frame constituted by n synchronization words each being either a first synchronization word or an inverted one of the first synchronization word; a communication frame generation part that generates a communication frame by adding the synchronization frame to a top portion of the data frame sequence; and a transmission part that transmits the communication frame. A reception apparatus includes: a reception part that receives the communication frame as a reception frame; a first synchronization detection part that performs first synchronization detection by detecting an arrangement pattern of the synchronization words in the synchronization frame of the reception frame; and a data reproduction part that reproduces data included in the reception frame according to the first synchronization detection.

Communication system, transmission apparatus, reception apparatus, and communication method

A system for controlling an electric device comprises: a power supply for supplying electric power to an electric device; switch portion connected between the power supply and the electric device for controlling the electric power supplied to the electric device; an LC filter disposed between the switch portion and the electric device; and current detection portion for detecting an electric current supplied to the electric device.
