The present invention relates to a signal transmission system, and more particularly to a hybrid transmission system for transmitting different directional signals by using an optical fiber and an electrical transmission line, which uses an electrical transmission line to transmit a master system. And a bi-directional control signal between the slave systems, and using the optical fiber to transmit a uni-directional data signal transmitted by the host system to the servant system. In this way, the hybrid transmission system can be easily implemented on the conventional handheld electronic device, and the image transmission rate and quality of the handheld electronic device can be greatly improved, and the main system and the servant system can be greatly reduced. Use the volume and complexity of one of the hybrid connectors.

In recent years, due to the continuous advancement of image display technology, various audio-visual equipments have brought unprecedented high-definition visual enjoyment to people, based on consumers' strong demand for high-definition video and its hidden huge Business opportunities, the industry has also continuously developed a variety of advanced audio and video interfaces to connect a video source (such as: desktop computers, Blu-ray players, etc.) and a display device (such as: computer monitors, LCD TVs, etc.), Among them, the Digital Visual Interface (DVI) and the High Definition Multimedia Interface (HDMI) are the most popular, and have gradually become the mainstream of the market. I only want to introduce the two interfaces. Features and specifications are as follows:

(1) Digital Video Interface (DVI): A video interface standard developed by the Digital Display Working Group's digital display working group to enhance the image quality of computer monitors through digital transmission. It has been widely used in LCD. On display devices such as TVs and digital projectors. In general, a DVI display system includes a transmitter and a receiver, wherein the transmitter is built in a display card chip of an image source (eg, a desktop computer, a Blu-ray player, etc.), and the receiver is It is a circuit on a display device (such as a computer monitor, LCD TV, etc.) that accepts the digital image signal transmitted from the transmitter and decodes it, and then plays it out by the display device. The DVI interface all transmits images in a digital format to ensure that digital video signals transmitted from an image source to a display device are less susceptible to noise interference, thereby maintaining the integrity of the digital image signals for presentation on the display device. Clear image; otherwise, the traditional VGA interface (the traditional 15-pin D-type connector) first converts the digital image signal generated by an image source into an analog signal, and then transmits the analog signal to a display device, and finally, through the display device. The conversion to digital video signals is initially presented. Therefore, the video signals transmitted by the traditional VGA interface are not only highly susceptible to noise interference, but also cause signal attenuation, which results in poor image quality compared to the DVI interface. Check, the number of terminals (Pin) of the DVI interface connector can be 19~29 terminals depending on the single channel and the dual channel, and the maximum transmission rate of the DVI interface is between 3.7 and 7.4 billion bits per second. Giga bit per second (hereinafter referred to as Gbps).

(2) High Resolution Multimedia Interface (HDMI): is an all-digital video/audio transmission interface for transmitting uncompressed audio signals and video signals, and has been widely used in set-top boxes, DVD players, and personal computers. , video game instruments, integrated amplifiers, digital audio and other audio and video sources, as a common data transmission channel between these audio and video sources and television. The biggest feature of the HDMI interface is the integration of video and audio signals, which is different from traditional video and audio transmission. In addition, it uses uncompressed digital data transmission to effectively reduce the signal interference and attenuation caused by digital and analog conversion. Compared with the DVI interface, the DVI interface is more suitable for computer monitors. The HDMI interface is more suitable for the transmission interface of the new generation of multimedia audio and video equipment because of the combination of audio transmission. Check that the number of terminals (Pin) of the HDMI interface connector is 19~29 terminals according to the specifications of the connector (A-Type and B-Type), and the maximum transmission rate of the HDMI interface has exceeded 10 per second. More than one billion bits (Gbps).

According to the above description, with the continuous improvement of high-definition digital image technology, the number of stream images of digital image (or video) signals transmitted between various image sources (or video sources) and display devices has increased significantly. Therefore, if the transmission interface between the image source (or video source) and the display device cannot provide a transmission rate of more than 1 million bits per second (Gbps), the image quality and resolution displayed on the display device are bound to be It will not be able to meet the basic requirements of high-quality images for general consumers.

However, since the aforementioned DVI or HDMI interface is applied between two independent image sources (or video sources) and the display device, as a interface for transmitting digital image (or video) signals, the DVI or HDMI interface connector itself is sized. The size, the complexity of the structure and the number of terminals in it, the design of two independent image sources (such as desktop computers, Blu-ray players, etc.) and display devices (such as computer monitors, LCD TVs, etc.) It does not have much impact. However, due to the large size, complicated structure and large number of terminals, these interfaces cannot be applied to all kinds of handheld electronic devices (such as laptops, mobile phones, and audio and video). In the player, etc., as an interface for transmitting digital video (or video) signals between the control circuit and the display circuit in the handheld electronic devices.

At present, various handheld electronic devices (such as laptops, mobile phones, video and audio players, etc.) have become an indispensable tool in people's daily life and work. The control circuits in these handheld electronic devices are The traditional RS-232 or I ² C interface is still commonly used between the display circuits for transmitting digital image (or video) signals. The RS-232 interface is the interface of the serial data communication developed by the Electronic Industries Alliance (EIA). The standard is widely used in computer serials. The maximum transmission rate of the interface is not more than 20,000 bits per second (bps). The I ² C interface is for the motherboard to be embedded. The system or mobile phone can be connected to low-speed peripheral devices, and the internal circuit integration interface developed in the 1980s is a serial communication bus, using a master and slave architecture, and the current maximum transmission rate of the I ² C interface. Up to 3.4 million bits per second (Mega bit per second, hereinafter referred to as Mbps). As can be seen from the above, in the conventional handheld electronic device, the interface for transmitting digital image (or audio and video) signals between the control circuit and the display circuit is incapable of adopting the RS-232 or I ² C interface. It is the responsibility of transmitting high-quality digital video (or video) signals (at least 1 Gbps per second).

Therefore, how to design a novel signal transmission system can be easily realized not only in the above-mentioned various hand-held electronic devices, but also greatly improve the image transmission rate and quality of the handheld electronic devices, and greatly reduce the size. The volume and complexity of the connector used between the control circuit and the display circuit of the handheld electronic device, thereby effectively eliminating the high frequency noise interference caused by the use of high frequency electrical signals to transmit image data by the conventional connector.

In order to have a better understanding and understanding of the purpose, circuit architecture and efficacy of the present invention, a number of embodiments will be listed and the drawings will be described in detail as follows:
