  1. This paper refers to several creation in compatibility with large volume of fed display and conversion of different video signal. it firstly used special central chip al300, designed correlative circuits, successfully developed vga full - color fed console system, compatible with resolution 1280 1024, achieved functions such as multi - video signal conversion and interleaving, met vga ’ s resolution of fed. it firstly designed and fabricated vga interface and separated video interface - - s - video, converting several video signals to 24 bits full - colored digital image signal in fed driving system, achieved separation of luminance signal and chromatism signal, enhanced the bandwidth of luminance signal

    首次採用平板顯示專用控制晶元al300 ，設計並製作了相關配套電路，支持的最高解析度是1280 1024 ，實現解隔行和多種視頻格式轉換的功能，滿足了fed顯示屏對vga解析度的要求。首次在基於fpga的vga級彩色fed控制系統中設計並製作了vga介面和分離電視信號s - video介面，可以將多種視頻信號變換為fed驅動系統可用的24位彩色數字圖像信號，實現亮度信號和色差信號的分離，提高了亮度信號的帶寬。
  2. Reasonable configuration : high - energy and memory - free battery has a large capacity, and a long service life. and led light source costs less energy and works longer. its service life can reach 100, 000 hours

    工作性能:光源打用特製超高亮度白色led ，可視距離達5000米:具有照明，點動頻閃和元距離信號燈指示功能連續照明時間10小時，充電時間8小時
  3. In this paper, chroma dc coefficients are selected as the carrier data because chroma dc coefficients are robust. also, alterable steps are used to select one part of the coefficients, so the watermark is imperceptible ; before watermark embedding, the watermark is divided into many parts, every part is individually embedded into one gop of the video, even if a gop is destroyed, the watermark can be extracted correctly, this methods promotes the robustness of the watermark ; in addition, in order to promote the security of the watermark, the user ' s id and password are used to generate chaos sequence by the chaos system which is created in this paper, later, watermark is mixed by the chaos sequence. also, the embedding position of the watermark bit is modified by one chaos sequence, so, unauthorized person can not extract or remove the watermark, since the embedding position is unknown

    本文認為，色度dc系數是魯棒性非常好的參數，因而選擇色度dc系數作為水印信息載體，同時，採用可變的步長選擇部分系數，保證了水印的隱形性；在嵌入水印時，本文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案，由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中，即使某一圖組收到一定破壞，也能夠恢復水印信息，使水印的健壯性得到提高；此外，為了提高水印信息的安全性，在嵌入水印信息時，根據用戶輸入的id號和密碼，利用本文構造的混沌系統產生的混沌序列對水印信息進行變換，同時，對每一水印信息比特的嵌入位置也採用了偽隨機序列進行調整，這樣，未授權用戶不能提取水印信息，也難以擦除其中的水印信息，因為嵌入的位置是未知的。
  4. While see the weight to carry the son to lose the outstanding and bad signal, and completely avoid to mix with to outputting of interference of bright degree, degree

    視頻分量端子輸出色差信號，完全避免混合輸出時的亮度色度干擾。
  5. Most of these standards are based on the method of inter - frame motion compensation and two - dimensional discrete cosine transform ( 2d - dct ) and encode and describe the color video in ycbcr 4 : 2 : 0 format, which want to take advantage of human visual system ( hvs ) to save bit expense by decreasing the resolution of two color difference components

    當前國際上的壓縮標準普遍採用幀間運動補償加幀內二維離散餘弦變換的編碼方法，並且將彩色視頻序列表示為ycbcr格式，試圖利用人眼的視覺特性降低對色差信號的解析度來節省比特開銷。
  6. The system adds the image recognition function on warning signal lights except the traditional video monitoring, remote control and collecting alert signals function etc. the methods for alert signal recognition include gray histogram arithmetic, pattern matching method and hsi system. the gray histogram arithmetic is the best method for this system

    除了實現傳統視頻監控系統所具有的監視、遠程控制、告警信號採集等功能外，增加了基於顏色特徵的告警信號燈圖像識別功能。確定了三種可用於基於顏色特徵的告警信號燈識別的方法：灰度直方圖法，模板匹配法和hsi系統法。
  7. There is two questions on transferring the video signals from the output of the hdtv decode to display on the screen, one is that we should convert the video data into many different video formats which is named as format conversion function

    經hdtv視頻解碼器解碼后的視頻信號在送去電視機顯示前需要解決兩個問題；一是對輸入的視頻格式可能做的視頻格式轉換（及yuv到rgb色度空間變換，稱為格式變換單元。
