New Description: [New Technology Field] This is a system, device and method for signal transmission, especially for the transmission system, device and method of video signals that are carried out by portable electronic devices. [Prior Art] In the current consumer electronics market, portable electronic devices such as multimedia playback, mobile phones, e-book readers and tablets have become very popular. For example, Apple's ipod, iPh〇ne or seldom and other products are in short-term, inward, and quite a sales volume and market share. Thanks to advances in microelectronics technology, these portable electronic devices are not only lighter in size, but their multimedia data or shouting processing capabilities are also becoming more and more accessible. At present, the high-definition television (HDTV) specification of high-definition (mail heart (10); (10) 'images, such as 72 〇p and face p signals, gradually replace the traditional standard resolution eve (= 480P) ❸ image format. In response to this trend, it has been increasingly possible for electronic devices to have an interface that can output high-definition signals. n A high-definition multimedia interface (High-Μ HDMI) corresponding to the same-definition image is a light-fit image. And the sound w only needs to be able to transmit uncompressed audio/video/Μ juice and 酉. The yeah (10) specification replaces the older analog video transmission interface such as SCART 5 #terminal' with digital video interface. Can be used for money TV and computer image formats, including 3 M435116. SDTV, HDTV video, plus multi-channel digital audio. During transmission, • - HDMI transceiver chip to minimize the transmission of differential video signals (Transition) Minimized Differential Signaling; TMDS) technology coded; data packet. The maximum elemental transmission rate is 165 Mpx/sec when the specification is first developed, enough to support 60 l〇80p enamel images per second, or uxGA resolution. (1600x1200); later expanded to 340 in the HDMI 1.3 version of the specification
Mpx/sec，以符合未來可能的需求。HDMI也支援非壓縮的8 聲道數位音讯傳送（取樣頻率192kHz，資料長度24 bits/sample) ’以及任何壓縮音訊串流如D〇lby Digital或DTS， 亦支援SACD所使用的8聲道的1 bit DSD信號。在HDMI 1.3 鲁 規格中，又追加了超高資料量的非壓縮音訊串流如DolbyMpx/sec to meet future possible needs. HDMI also supports uncompressed 8-channel digital audio transmission (sampling frequency 192kHz, data length 24 bits/sample) 'and any compressed audio stream such as D〇lby Digital or DTS, also supports 8 channels of 1 used by SACD Bit DSD signal. In the HDMI 1.3 Lu specification, an ultra-high-volume uncompressed audio stream such as Dolby is added.

However, the price of HDMI cables on the market is still high. In addition to the disadvantages of higher price, one of the main problems of HDMI cable is the limitation of length. The 28AWG specification HDMI copper wire of ^^ starts to signal attenuation after about 5 meters. 'The space source signal cannot be satisfied. The need to connect between a projector or a TV. Although increasing the diameter of the copper wire in the cable to reduce the impedance is a method to effectively extend the length of the winding - it will increase the price and lead to a higher price. ί I = too rough, affecting the appearance, not secret, It will also improve the difficulty of wiring indoor spaces. On the one hand, °. The company has become more and more popular, and Apple, I, iPhone and iPad products are not equipped with HDMI output interface, and oh, use the "designed 3-pin base connector (Μ connector), negative shell Output audio and video and other digital slings (Dlgltal AV Adapter), in order to output 4 HDMI signals to the display device, HDMI _, as shown in the figure, a little longer distance must be connected again, the pattern No. Because Η_ age 7 is at the upper end of the length, the use of d 5 uses the * type and its extendable distance is still very good. The loose _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _捭气雷+驴App, e lPod, lPh〇ne ^ ^^?!!:; Transmission system, which can be used to: (10) - use the signal (4) (4), also suitable for [new content] The signal of the video 3 outputted by the portable electronic device can be transmitted over a long distance via a υτρ cable (for example, Ca; 5e or 2), and the signal is converted to 1 at the receiving end. Display device - such as a flat panel display or projection device - υτρ transmission There are two ways to listen to audio signals, the other is signal reconstruction. The way of network (LAN), the analog video signal, the choice of compression or no compression loss first type processing ' Through the ΡΗ γ of the device, the 阙υ τ ρ line is transmitted back to the video and audio data at the receiving end. The advantage of using the network (LAN) to transmit video and audio is that the error code will be less, and the distance can reach about 1 (8) meters. The second method is called signal reconstruction. At the transmitting end, the signal is transmitted to the receiving end through the RJ45 socket through UTP. Because of the transmission distance, the signal will be attenuated and deformed. At the far-end receiving end, the signal needs to be compensated and The advantage of transmitting signals by signal reconstruction is that the price is cheap and the installation is simple. The disadvantage is that the distance can only be within 45 meters, and it is also susceptible to external interference. Referring to the second figure, the main technical content of this creation includes An audio-visual signal transmitting device 1 and an audio-visual signal receiving device 2. The video signal transmitting device 1 includes a first signal input interface, which is an Apple base The connector is configured to connect a product such as an iPod, an iPhone, or an iPad to receive one of the first audio and video signals output by the portable electronic device; and a first signal conversion unit 12 configured to convert the first audio and video signal into a A transmission signal transmitted by the UTP cable 3 and a first signal output interface 13 are used for outputting the transmission signal, and the UTP cable 3 is connected to transmit the transmission signal to the aforementioned video signal receiving device 2. The signal receiving device 2 includes a second signal input interface 21 for connecting the UTP cable 3 to receive the transmission signal, and a second signal conversion unit 22' for converting the transmission signal into a second video signal; A second signal output interface 23 is configured to connect and output the second video signal to a display device. The transmission signal may be in different aspects, such as a data packet format conforming to a network protocol or a general analog signal. In addition, the video signal receiving device can select a signal equalization unit to form an active signal transmission system, and the signal equalization unit can correct the distorted signal waveform before the second signal output interface to enable transmission of the system. The distance is more extended, up to about 1000 feet (depending on the configuration and design of the system). In the system disclosed in the second figure, the mechanism and appearance of the video signal transmitting device 1 and the shirt tone receiving device 2 may have different types, such as a transfer or a Wall Plate. The first signal input interface 11 can be used to set the Apple base connector to the surface of the housing of the AV signal transmission device 1, or the M435116 is a Pigtail type that extends a length of wire. The video signal transmitting device 1 can further be provided with a power input terminal or a USB connector for connecting the external power source to supply power to the portable electronic device. On the other hand, in the video signal receiving device 2, the second signal output interface 23 can be an HDMI or other connector, such as a DVI, VGA, USB, RCA terminal (a color difference video signal and a multi-channel audio signal). The same can be set to the surface of the video signal receiving device 2 or a pigtail type that extends a length of wire. With the signal conversion and transmission system of the present invention, the disadvantages of the prior art described above can be overcome, so that the video signal output from the portable electronic device is transmitted farther and the flexibility of the wiring is higher. [Embodiment] The consistent application of this creation is shown in the third figure of the drawing. The audio-visual signal transmitting device 1 and the scenic sound receiving device 2 are of a box shape, the former has a pig tail type Apple base connector m and an RJ45 connector 131, the latter having an RJ45 connector 211 and a pig tail Type hdmj connector f 1. Between the RJ45 connectors πΐ and 211 is connected by a υτρ cable, or a Cat6 wire.
