摘要： PROBLEM TO BE SOLVED: To provide a communication system for vehicles that can change image compression rate according to the display details in a navigation image.
SOLUTION: A first communication station 2a comprises a navigation system 4, an image compression apparatus 8 for compressing the navigation image data obtained by the navigation system 4, and a CPU 10 for control so that the image compression rate in the image compression apparatus 8 can be changed according to display details that are displayed by the navigation system 4. Then, when for example block compression is used as a method of image compression, the compression rate is switched to a higher compression rate than normally when the image of the navigation system is set to be a scroll image, thus restraining the deterioration in images in screen scroll, and reducing the transmission capacity in image signals.

摘要： PROBLEM TO BE SOLVED: To provide a system with an enhanced data transmission efficiency wherein each apparatus synchronously transmits frames while the frames are assigned with a data area used for each apparatus, data are being stored to and extracted from the frames for the purpose of data transmission/reception.
SOLUTION: In the case of transmitting data from each of apparatuses 1 to 4 in the data transmission system, when a data capacity of transmission data is less than a data area assigned to its own apparatus, the apparatus writes an idle area to a header area of the frame and writes the transmission data to the data area assigned to its own apparatus and transmits the resulting frame, when the data capacity of the transmission data is more than the data area assigned to its own apparatus, the apparatus references the idle area written in the header area, writes the transmission data to the data area and the idle area assigned to its own apparatus and transmits the resulting frame.

摘要： PROBLEM TO BE SOLVED: To provide a video signal communicating system whose structure can be simplified and that can avoid congestion of signal transmitting paths. SOLUTION: A first communication station 2a, a transmitting side of video signals, has: video interfaces 4, 5 that take ODD signals or EVEN signals out of two video signals that are inputted; a logic IC 8 that generates video signals with which the ODD signals or EVEN signals for each video signal are synthesized; and an encoding IC 9 that compresses the images of video signals after synthesized by the logic IC 8. Also, a second communicating station 2b, a receiving side of the video signals, has: a decoding IC 23 that extends the video signals outputted by the first communication station 2a; a logic IC 22 that separates the ODD signals or EVEN signals from the extended image signals; and video interfaces 26, 27 that generate desired video signals by copying the separated ODD signals or EVEN signals and by generating abridged video signals. As a result, the system structure can be simplified.

摘要： PROBLEM TO BE SOLVED: To provide an optical multiplex transmission system that is simplified without the provision of a start signal electric wire other than a data transmission line and which starts each control node. SOLUTION: A light receiving section 11 of each control node which connects to an optical multiplex transmission line is operated by the application of power from a power supply 14 and receives an optical signal from other control node. A mode switching section 23 alternately selects a multiplex communication mode or a sleep mode for each prescribed time. A light receiving section power supply control section 24 and a 1st switch 15 generate a power supply signal, where the duty factor of a power supply time nearly corresponding to the multiplex communication mode and a power supply non-application time nearly corresponding to the sleep mode is preset and supply the signal to the light receiving section. When multiplex communication mode is selected and an optical signal is received, a mode changeover section continues the multiplex communication mode during the reception of the optical signal and the light receiving section power supply control section continuous the supply of power by a power supply signal to the light receiving section.
