Description of the invention: [Technical field to which the invention pertains] The present invention relates to a display for electronic video, and more particularly to a display capable of receiving visualized data via wireless communication. [Prior Art] Television and computer screen systems typically receive visual material via wired media such as coaxial cable, analog video, digital video interface (DVI) or high resolution multimedia interface (10) MI. The computer screens and televisions produced under the current technology receive input signals in digital form or through the line transmission and signal. Early televisions received broadcast signals from wireless transmissions; sometimes local antennas such as the "rabbit ear antenna". However, early analog broadcasts were susceptible to interference, and the signal resolution was far less than the existing high-tech broadcast signals. Compared with the wired interface, the wireless interface has its inherent advantages. A wireless display device can be flexibly placed anywhere in the home or office without being bound to the coaxial cable connector or the host computer. Computers with wireless peripherals, such as keyboards, mice, and printers, are so popular that the data transmitted by such wireless devices is smaller than the bandwidth occupied by video data to the screen. Therefore, a visual display capable of receiving video data through a wireless channel would be desirable. # ^ 17 [Summary] In this case, a video display system is provided, which is a signal source device that transmits digital video and audio signals to a wireless video display through an ultra-wideband connection. The aforementioned transmission system wirelessly transmits source data generated by a video interface such as digital RGB, DVI or VGA to the display device. This source device transmits and controls the image and reproduces the image. The video source may be a removable computer device. The aforementioned source devices can adjust the recovery rate and/or interleaving techniques to bring the data delivery rate to the wireless bribe. The towel is a specific implementation. The source device only updates the image data of the changed part of the screen. This update mechanism allows the original signal (eg, MN) 1287395 to be reproducible in a resolution-optimized format on a display device. In another embodiment of the present invention, the source device includes a distortionless compressor and wireless plus corresponding decompression! _Efficient operation and better performance table [Implementation] • Any radio technology has a spectrum of exposure, which has a 20% reduction in the consumption. = or at least 500 For ultra wideband (10) B). Today's ultra-wideband systems benefit from the OFDM technology of Orthogonal Frequency Division Multiple Access (_) to achieve very large frequencies. Orthogonal Frequency Division Multiplexing (〇) achieves frequency division multiplexing, allowing subcarriers to overlap frequency bins without interfering with each other, thereby increasing spectral performance. Orthogonal frequency division multiplexing for ultra-wideband transmission The multiplexing technology produces a new physical layer system, which can achieve high-speed, short-distance network transmission. Each band is uploaded by _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Accurately segmented carrier. In this technique, the adjustment interval provides orthogonality and mutual interference. (4) M gamma includes hyperspectral performance, radio frequency interference recovery (RF), and low retransmission distortion. The physical layer is an example of an ultra-wideband system based on 0-shun. The physical layer is based on multi-frequency π OFDM (MB-OFDM) technology. The multi-band kneading system wirelessly transmits data packets at a very high speed. Such ultra-wideband technology can transmit hundreds of megabits or even gigabits of digital data per second. • In addition to the MB-OFDM system, the case can also be combined with other physical layers or media access control layer (MAC). As shown in Figure 1, the system is based on this The desktop computer system and its wireless peripheral device. The present invention provides a mechanism for the electronically known screen, television group and other display devices to receive data data through a high-speed wireless system through ultra-wideband (UWB) technology. In other words, the host computer (100) exchanges data with the keyboard (1〇2), the mouse 1287935 (103), and the display screen (104) by the wired data connection (Π0) (1Π) (Π2). (100) It may also be equipped with other wireless peripherals, such as printers. It is common for today's computers with wireless peripherals such as keyboard (102) and mouse (1〇3). The bandwidth required for data is less than that required to transmit video data to the display screen. Even if the large bandwidth can achieve wireless multi-frequency Internet access, it still cannot satisfy a large number of high resolution, especially the emerging high resolution. The video data transmission requirement of the screen. The present invention provides a wireless display screen (104) for receiving a digital video signal transmitted through a wireless high-speed ultra-wideband (UWB) connection (112). The digital video signal includes digital RGB. Signal (RGB), digital video receiving interface (DVI), high-resolution multimedia digital transmission interface (HDMI), video graphics array (VGA), analog components such as digital/analog ratio (D/A) converters, or other video signals. The second is a system architecture diagram illustrating the wireless digital video interface of the present invention. Through wireless transmission, digital audio/video (A/V) data is transmitted from the video transmitter (210) to the wireless display (220). In this embodiment, The line-transmitted A/v signal output by the video source device (2.1) is processed by the video processor (211), received by the buffer (212) and ready to be communicated to the ultra-wideband subsystem (213). The conditioning transmitter (210) transmits the signal at a fixed rate and synchronizes the screen data with it. The foregoing processing may include formatting the digital A/V signal stream into data packets and compressing the packets into a UWB information frame; it may also include color space conversion or quantization of digital signals. In the transmitter (210), the video processor (211) is responsible for multiple tasks; including quantized data, color space conversion, and compressed data. It is also responsible for regulating the rogue parameters of the ultra-wideband subsystem (213). An ultra-wideband (UWB) message box (or packet) is transmitted wirelessly between a transmitter and a receiver. Each ultra-wideband information frame consists of a synchronous transmission sequence (preamble and frame start symbol (SFD), a physical layer (ΡΗΥ) header and a protocol data service unit (psDU). Each nine 7 1287395 association The Data Service Unit (PSDU) in turn contains a Media Access Controller () header and a _ MAC Data Service Unit (_). The Data Service Unit (10)_ can be considered as the data payload for transporting partial information frames. The signal is the pseudo-relay sequence used by the display (220) to obtain the signal. The physical layer convergence program (PLCP) header provides the frame length of the media access controller (10) 媒体 = media access control ϋ provides # ΡΗ γ ( The physical layer) lion and _ check sequence code (HCS). The protocol data service unit (psDU) is the data load. > The ultra-wideband subsystem (221) of the aforementioned wireless display (10) receives the digital A/v packet and some The sealed (four) A/V signal stream is reproduced as the original sharp, which is presented in the line-by-digit digital A/V interface in the display screen (10). * * In addition to the video data, the wireless link (230) also transmits control information to maintain the connection integrity: 3 = message helps maintain the quality of the wireless link, and thereby maintain a high quality video over broadband subsystem (221 Each of the ultra-wideband information frames is received by the signal forcing and each decoded video information frame is then transmitted to the video processing device (222). The video processor (222) at the receiver end performs quantization inversion and color 再 again.

However, when the output capacity of the ultra-wideband subsystem is higher than the digit = 1287395 and the data is required for the flow demand, the ship reduction machine will only perform data packing for other programs. Fig. . . is a wireless digital video interface architecture according to the present invention, which comprises a data reducer. In this embodiment, the present invention further provides a de-compression (322) at the video transmitter (with a two-distortionless compressor (313) and relatively at the receiving device (32〇) end.

The digital data __ key is a two-test Q1 module that finds money. Undistorted compression makes the compressed data completely _ original. Unlike this case, other video compression systems, such as Animation Expert Group 2 (MPEG-2) compression, can cause high distortion of video. In an embodiment of the distortion-free video compression technique, the video material is compressed on one or more lines of video data. Other video coding systems, such as MPEG-2, differ from this case in that they compress data onto multiple information frames. Therefore, the MPEG-2 system will generate more delay than the technology of this case. Through the coupling of the compressor (313) and the decompressor (322), the present invention achieves instant compression/decompression without compromising image and signal quality, resulting in high resolution video images and accurate audio signals. Figure 4 is a system architecture showing a wireless display including a screen buffer in accordance with the present invention. This embodiment includes a mechanism for updating only the changed portion of the displayed image. The transmitter has the function of controlling the screen one by one; if no change occurs, the update signal will not be sent 'or zero transmission; if only a small part of the screen changes, only the part to be updated is transmitted (for example, the upper left corner and The lower right corner position) and related data of this block. The wireless display receiver (420) includes a full video buffer (423) that allows the entire information frame of the data to be buffered at the receiver and updated based on information received by the transmitter (4).
