摘要： A video display device which does not confuse the viewer when the viewer changes the displayed video. The video display device (1) comprises a video processing section (11), a display section (12), and a control section (14). The control section (14) controls the video processing section (11) to display one content for first and second viewers on a display section (12) in a one-screen display mode. When the first viewer operates a button installed for the viewer in the one-screen display mode, the display section (12) displays the displayed content on the first screen for the first viewer and on the second screen for the second viewer in a two-screen display mode. When the first viewer further operates the button installed for the first viewer, the display section (12) displays, in the two-screen display mode a different content on the first screen and the content which has been displayed on the second screen.

摘要： A data transmission system in which normal transmission can be performed irrespectively of the inserting orientation of a connector is provided. A transmitting device transmits to a receiving device a differential transmission signal including polarity decision data for deciding the polarity of the connector. Based on the polarity decision data included in the differential transmission signal transmitted from the transmitting device, the receiving device decides whether the polarity of the connector has been reversed or not. When it is decided that the polarity has not been reversed, the receiving device reads data from the differential transmission signal. When it is decided that the polarity has been reversed, the polarity of the differential transmission signal is reversed for data reading.

摘要： To a data reception device, a signal having a frequency of 12.5 MHz and including data is transmitted. The data reception device generates a clock B having a frequency of 400 MHz of (1) in FIG. 8, and performs sampling for the above-described 12.5 MHz signal based on the clock B ((2) in FIG. 8). Then, the data reception device detects zero cross points of the sampled data, and generates a 25 MHz frequency clock signal indicating the zero cross points ((3) in FIG. 8). Next, the data reception device generates, by delaying the generated clock signal by the time amount corresponding to eight clocks ((4) in FIG. 8), a 25 MHz signal indicating symbol points. Thus, symbol points can be detected.

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 signal receiver (11) receives an analog signal via a twisted pair cable (31). An A/D converter (12) converts the analog signal to a digital signal. A phase detection unit (14) detects the phase of the digital signal, and generates a reception timing signal. A transmission timing generation unit (15) controls, based on the reception timing signal, timing for a transmission processing unit (16) to output the digital signal such that the reception signal (point A) and a transmission signal (point D) are different in phase by a predetermined degree. The transmission processing unit (16) outputs, in accordance with the timing, a digital signal obtained by performing mapping on data inputted from a connection device (20). A D/A converter (17) converts the digital signal to an analog signal. A signal transmitter (18) transmits the analog signal via a twisted pair cable (32).
