Embodiment Construction

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0017] figure 1 The structure of a signal transmission system of the first embodiment of the present invention is shown. A first signal transmission device 10 and a second signal transmission device 20 are connected through a transmission line 30 . The transmission line 30 is composed of a plurality of high-speed serial buses 301-307 and a low-speed serial bus 310 whose transmission speed is lower than that of the high-speed serial buses 301-307.

[0018] The signal transmission device 10 includes an image transmission processing unit 11 that generates an image signal as its content. More specifically, by adjusting the resolution and based on the image control signal TG fed from a control unit 19 which will be described below a The number of colors, the image transmission processing unit 11 generates a serial image signal DG of three primary colors a , ...

Abstract

The present invention relates to a signal transmission device and a signal transmission method. The signal transmission device includes a first communication device for transmitting a signal through a plurality of high-speed serial buses, and a first communication device for transmitting a signal through a low-speed serial bus. A second communication device for transmitting a signal to the low-speed serial bus of the high-speed serial bus; a transmission line is composed of the multiple high-speed serial buses and the low-speed serial bus, and each signal transmission device Provided on the terminal side of the transmission line, a signal transmission operation through the high-speed serial bus is controlled based on a result of communication through the low-speed serial bus.

Description

technical field [0001] The invention relates to a signal transmission device and a signal transmission method. Especially in signal transmission, in the case of transmitting signals through a transmission line, the transmission line is composed of a plurality of high-speed serial buses and a low-speed serial bus whose transmission speed is lower than the transmission speed of the high-speed serial bus, through Signal transmission operations of the plurality of high-speed serial buses are controlled based on results of communications through the low-speed serial buses. Background technique [0002] As is well known, computer equipment or similar equipment can convert a digital image signal into an analog image signal, and transmit it to a display device through analog transmission. However, with the expansion of display devices, the display units of which are driven by digital signals, such as liquid crystal displays; in order to prevent the degradation of image quality and ...
