As a lighting de-signer, I had dabbled in video but had never treated it seriously, nor was I taken seriously. Once I was introduced to the Pandoras Box range and understood the capabilities of the systems and software, it changed my approach to production design. No longer did vid-eo need to be a separate element. I could then envision a stage design with all the luminous elements and provide a serious video solution. The ability to lock to, or generate time code makes my video content all the more powerful on broadcast work. The tools made available from Pandoras Box have given this old dog many new tricks, and they seem to keep coming.”Paul Collisoneleven DESIGN / Managing DirectorAustralia“We have been using Pandoras Box since 2012 and have discovered that this product offers so much more than one could possibly think. Pandoras Box became not only our default tool for projection map-ping, 3D tracking and uncompressed playback, it has also been used to simulate and automate complex kinetic scenery movements, such as in our production ‘Overture’ by David Dawson. Widget Design-er has even found its way to our foyers, giving employees control over light, video and sound installations. In the opera world, it’s well-known story nearly anything is possible at Dutch National Opera & Ballet – much to the power and performance of Pandoras Box!”Pieter HuijgenDutch National Opera & Ballet / Head of light/video/stageNetherlands“We have been using Pandoras Box since the very beginning. When it was first introduced 10 years ago, Pandoras Box was the benchmark of possibilities and flexibility. And today, it still is! From large-scale projection mapping, uncompressed image sequences in resolutions far greater than 4K, to complex permanent installa-tion in museums or exhibitions, like the Expo 2017. Pandoras Box is not only a technical solution for us – it´s a tool that breaks the boundaries of technical and creative limitations. With Pandoras Box, we are able to bring every idea and concept to life. When you combine inspiration with a powerful tool like this, you´re able to not only inspire your clients, and customers, but even yourself!Benjamin Brostian AV ACTIVE / CEONik Burmester Burmester Event- & Medientechnik / CEOGermany19“When doing a magic show, timing and accuracy is key. Essen-tial to this is our technical setup, wich we often rely upon to make our tricks and the entire show work. Whether its for video and audio playback, SMPTE control for lighting, DMX triggers for fog or flames, projector control or just the rise of the curtain at the just the right time – we trust Pandoras Box and Widget Designer. The versatile timeline programming combined with the flexibility of the Widget interface allows us and our crew to be spot-on, everytime. We first discovered the reliability and easy adaptability of Pandoras Box back in 2008 – and it’s been an indespendsible tool since. It really gives us the freedom to think outside the box in our show design.”Ehrlich BrothersGermany“To me and my team this perfect technical instrument allows us to realize ideas in the most effective way. With great flexibility and no technical boundaries, in the best quality possible and with extreme reliability. All this helps us to turn our big picture ideas into a beautiful reality. In the end, it`s still the people, hu-mans and their passion and ideas for creating, innovating and touching others deeply. If the tools are cool, they can even in-spire you to create something even beyond your own and your clients’ expectations.”Matt Finkeloop light / CEOGermany“Since 2005, we have been proud to be part of the innovative and visionary Pandoras Box team as early adopters of Pandoras Box, the world’s most powerful media server. We have literally built our business as Video Projection Experts on the Pandoras Box product family. We value the company’s unwavering com-mitment to dialogue and partnership with their customers, and to continual improvement of the products.

数字视频设计制作课设说明书
目录第1章课程设计构思和作品内容 (1)第2章课程设计步骤 (1)第3章课程设计总结 (5)参考文献 (8)第1章课程设计构思和作品内容一、构思：我制作的课设题目是《北京城市形象宣传片》，我个人很喜欢北京这个城市，所以我决定搜索资料，做一个北京的城市宣传片。
我想对城市的宣传，主要需要体现一个城市的特色、历史渊源、文化底蕴、标志建筑等。
因此，我在视频、图片素材的选择上，尽量挑选有背景特色的素材，如天安门、国庆阅兵、长城、故宫、北京大学、京剧、天安门升旗仪式、奥运会等。
因为北京是祖国的首都，是经济政治文化的中心，所以，一些中国特色的事物同样能够表现北京的特色，如水墨画、武术、太极等。
北京是一座国际化的大都市，是和谐融合中西方文化的典型代表城市，因此，我想选用一些中西文化的碰撞来表现这一主题。
二、内容：开头是一个放大镜在地图上寻找北京，随着“北京”二字的不断放大，进入宣传片的主要内容。
随着强节奏的京剧鼓点，一个个身姿曼妙，功夫了得的京剧演员出场了。
随着音乐的变化，大门开启，一幅幅北京古代标志建筑和现代人的生活穿插在一起，表现了北京是一个古今融合的城市。
又是一段强节奏的，令人激昂振奋的音乐，画面中出现了国庆阅兵的壮观画面，中间穿插着北京奥运会留下来的标志建筑——鸟巢和水立方。
接下来表现的是北京市民的文化和艺术。
舞蹈、武术、水墨画、民间手工艺品，这些都是北京的特色和北京市民积极向上风貌的体现。
芭蕾舞、歌剧与中国舞蹈、古代宫殿与现代高楼大厦，外国游客与北京市民，一个个鲜明的对比，都体现出北京是一座融合东西方文化、融合古今文化、富有历史和文化底蕴的，现代化的大都市。
第2章课程设计步骤一、确定主题：我个人喜欢北京这个城市，因此我想要做一个宣传片来宣传北京，同时也希望借助制作宣传片的机会，加深对北京这个城市的了解。
二、搜集素材：我在优酷视频网上下了一些北京的城市形象宣传片、北京申奥宣传片和北京奥运会宣传片。
同时，我还在百度网上搜集了一些具有北京特色的图片，一些北京的标志性建筑和标志性事件。

In order to process and transmit the high definition video, the design combines FPGA and SOC, follows the H.264 video coding compression. The FPGA realizes the high–speed video acquisition via Cameralink interface, and convert the raw image to ITU-R BT.1120 stream. The SOC contains CPU and Codec, it compresses the BT.1120 stream to H.264 steam and transmit the stream in the network. The low-delay rate control algorithm can limit the bitrate in a very low level. The result shows that the system reduces bandwidth and lowers the latency, the design is adaptable to the real time environments.Keywords-FPGA; H.264; ITU-R BT.1120; Low latency;I.I NTRODUCTIONIn recent years, there is an urgent demand of the high resolution image processing in the aerospace, opto-electronic detection and other fields [1], such as Full HD (High Definition) video. The HD video (1920 pixels x 1080 pixels 30 frame per second) has huge data, and is difficult to be processed on the traditional image processing platform. So the video compression is needed. H.264 as the new generation video coding standard, has greatly improved the image quality and bitrate control. This paper uses the FPGA and SOC (System On Chip) with hardware and software combination, designs and implements a network video communication system on the H.264 coding algorithm.II.S YSTEM H ARDWAREThe system contains the CCD camera, FPGA, SOC and some peripheral hardware. The camera transmits the images by the CameraLink interface. The FPGA is Spartan-6 [2], it processes the digital image, converts the image to ITU-R BT.1120 video stream [3], and then, transmits the stream to the SOC. The SOC is MG3500 [4], it contains a ARM9 CPU and a H.264 codec, the codec encodes the video to H.264 stream in real time, the CPU transmit the stream in the network at last. Fig.1 shows the system architecture.Figure 1. The hareware frameworkIII.FPGA D ESIGNA.Video acquistionHigh definition digital video is transmitted from camera to FPGA via CameraLink interface, and then buffered in the DDR2 SDRAM. Spartan-6 has the specialized MCB core for the DDR access, DDR2 SDRAM can read and write data conveniently. In order to balance the speed of the image data input and output, one frame must be buffered at least; the ping-pong operation is also used to ensure the image integrity. So the system design use DDR2/800MHz as the frame buffer for the high speed image data access, and open two frame buffers for ping-pong operation.The CCD pixels are preceded in the optical path by a color filter array (CFA) in a Bayer mosaic pattern, in order to get real color images, the raw image should be processed in the pipeline including demosaicing [5], auto white balance and auto gain control [6].After that, the Bayer pattern image is converted to RGB image.B.BT.1120 conversionAfter all the image processing above, the digital image should be converted to BT.1120 stream.The BT.1120 is the recommendation of digital interfaces for HDTV studio signals. It complies with the characteristics described in Recommendation ITU-R BT.709 [7]. BT.709 contains some HDTV studio standards to cover a wide range of applications including Common Image Format (CIF) system which has 1125 total lines and 1080 active lines. The standards contain opto-electronic conversion, picture characteristics, picture scanning characteristics, signal format and analogue representation. BT.1120 also follows these standards, and then contains more such as bit-serial data format and transmission format.BT.1120 video interface supports 10-bit and 8-bit video data transmission, the video data format can be RGB 4:4:4 or YCrCb 4:2:2. First, the color space should be converted from RGB to YCbCr. The raw digital RGB color has 3 components including Red, Green and Blue. Each component has a value between 0 and 255, corresponding to 8-bit quantization. In accordance with BT.1120 recommendation, the value should be normalized as in (1)255/,255/,255/R E G E R E R G R === (1)YCbCr is not an absolute color space; rather, it’s a way of encoding RGB information. It contains the luminancecomponent(Y), blue-difference component (B-Y) and red-difference component (R-Y). In accordance with BT.1120 recommendation, the YCbCr is derived from RGB accordingto the following transform:0.07220.7152 0.2126 R B G Y E E E E ++=()8556.19278.07152.02126.09278.05.0B G R Y B CB E E E E E E +−−=−= (3)()5748.10722.07152.07874.07874.05.0B G R Y R CR E E E E E E −−=−= (4) After the transform, the signal should be quantized. In BT.1120 recommendation, as 8-bit quantization, the Y component has 220 steps, the value 0 is mapped to 16; the Cr and Cb components both have 255 steps and 0 is mapped to the median, 128. So the quantized signal is derived as follows:()5.16219int +=Y Y E D (5)()5.128224int +=CB CB E D (6) ()5.128224int +=CR CR E D (7)D Y , D CB , D CR respectively represents the quantized digital YCbCr signal. For FPGA to achieve, fixed-point decimal arithmetic can be multiplied by a factor into integer arithmetic. All the values in (5)~(7) are multiplied by 1024, the new transform is (8)~(10):1024187 6296316896Y D R G B =+++ (8)131584450347--1031024++=B G R D CB (9) 131584414094501024+−−=B G R D CR (10)After the color space converted, the signal should be sampled. ITU-R BT.1120 describes the YCbCr signals in4:2:2 sampling rate. This system uses the 8-bit color space,so that each pixel has 16 bit data composed of achrominance(C) component and a luminance(Y) component.In accordance with the bit-parallel interface in BT.1120, Cband Y are transmitted in odd numbers of pixel clock; Cr and Y are transmitted in even numbers. The sequence isrepresented as:(Cb 1 Y 1) (Cr 1 Y 2) (Cb 3 Y 3) (Cr 3 Y 4)… The FPGA can convert the image from RGB to YCbCr in parallel processing rapidly, the conversion can be completed in two timing cycles while nine DSP multipliers are used. The data path is shown as Fig. 2.Figure 2. YCbCr conversion.ITU-R BT.1120 digital interface contains only the videodata signal without a separate control signal. it use the timing reference codes to identify the line and frame. There are two timing reference codes embedded into video data stream, one at the beginning of each video data block(start of active video, SAV) and the other at the end of each video data block(end of active video, EAV). These codes are contiguouswith the video data, and continue during the field/frameblanking interval.Each code consists of a four-word sequence. In the 8-bit implementation, the bit assignment of the word is given in Table I. The first three words are fixed preamble and the fourth word carries the information that defines fieldidentification (F), frame blanking period(V), and line blanking period (H). TABLE I.

The value of protection bits, P0 to P3, depends on the F, V and H as shown in Table15. The arrangement permits one-bit errors to be correctedand two-bit errors to be detected at the receiver, as shown inTable II.TABLE II.

The bits F,V and H are mapped to the ROM address, the protection bits are stored in the corresponding address. When encoding the timing reference codes, the bits are read from the ROM address and then combined with it.IV.L OW L ATENCY R ATE C ONTRLThe SOC can encode the BT.1120 stream to H.264 data. Under the prerequisite of image quality, this paper designs a low-delay rate control algorithm to reduce the transmission bandwidth and lower the delay.The rate control algorithm uses data on the size of past frames to estimate the size of future frames. It uses its algorithm to decide if the size of future frames must be changed in order to meet performance requirements such as bitrate and latency.Rate control algorithms are usually classified as VBR (Variable Bit Rate) and CBR (Constants Bit Rate). CBR generally means maintaining the specified bitrate over time. VBR generally means that the rate control is allowed to generate a bitrate much lower than specified when the image is easy to encode. This is intended to prevent wasting bits, if a lower bitrate can achieve a high quality. This paper uses a VBR algorithm.Low latency encoding is the most difficult case for the rate control, since it is typically used for network streaming. Network streaming usually requires a low transfer rate due to limited bandwidth, so this produces the rate control’s worst case scenario of low latency plus low transfer rate. Therefore, this section refers to "low latency" encoding but actually means low latency plus low transfer rate.A.Rate comtrolOn MG3500, the algorithm set the slice QP (quantization parameters) value in order to control the long term bitrate. In AVC encoding, the QP value controls the quantization of all coefficients in the frame [8]. More quantization (a higher QP value) means fewer bits per frame, and less quantization (a lower QP value) means more bits per frame. The QP values range from 0 to 51. For the VBR application, the minimum QP value is set to 20.The rate control use separate parameters for the bitrate and for the transmission rate. The bitrate is an approximate target for the size of the bitstream. The transfer rate is an absolute upper limit on the size of the bitstream. The transfer rate controls the fluctuations of the bitrate.If the transfer rate is set much higher than the bitrate, then the bitrate may rise very high for short periods. If the transfer rate is set close to the bitrate, it places a limit on how high the bitrate can increase within a short period.The transfer rate represents the rate at which data can be transferred to the decoder. In the case of network streaming, the transfer rate should be set to approximately the maximum bandwidth available. The transfer rate should not be set low unless this is required. A lower transfer rate limits the rate control when it is choosing the short term bitrate. This will generally result in a long term bitrate, because the rate control will tend to produce smaller frames in order to avoid exceeding the transfer rate. The risk of frame drops is also increased.Recommended transfer rates are 1.5 x bitrate for low latency applications.B.Low latencyThe rate control includes explicit setting parameters for the target latency. Technically, this is the amount of data the decoder is expected to buffer before starting playback. In reality, it affects the overall latency between the encoder and the decoder. The rate control’s latency setting does not control the overall latency, which depends on encoder and decoder settings and the network delay. However, the rate control must be set to support this latency or it will occasionally produce frames which are too large, and cannot be transmitted to the decoder when it requires them. The latency setting can only be understood in combination with the transfer rate setting above. The latency controls the number of frames which can be buffered up between the encoder and the decoder, and the transfer rate controls how fast those frames are actually transmit. The two of these together control the size of the frames.If the latency is low but the transfer rate is very high, only a few frames can be buffered but their size does not matter. Even if they are very large, they can be transmitted before a new frame is encoded and there will always be a small number of buffered frames. But if the transfer rate is low but the latency is very high, many frames can be buffered. A few large frames will be averaged with many smaller frames, and they will not exceed the buffering limit.Only if both latency and transfer rate are low does the rate control’s behavior change substantially. As latency and transfer rate are reduced, the actual bitrate will fall further below the specified bitrate. The rate control cannot use the full bitrate, or it will risk generating a frame which is too large to transmit to the decoder on time. So the recommended latency for the network is 4 frames(133ms).the H.264 coding chose high profile and level 4.1 feature, using the IP GOP (group of Pictures) structure [8] with only I-frame and P-frame ,the B-frame is not used to lower the decoder’s latency.V. N ETWORK T RAMSMISSIONAs a video network communication system, network transmission is also very important. After encoding, the H.264 stream is transmitted in the network over TCP/IP.Video communication has high real-time requirements. In order to ensure that the transmission of the image will not obviously delay the system in the unknown network, UDP protocol is used in the transport layer for network communications.Considering the complexity of the data packets out of order in the transmission network, this will bring some error in real-time decoding to affect the image quality, the system has completed the RTP (Real-time Transport Protocol) protocol [9]. RTP is an application layer protocol, which also use UDP in the transport layer, not a connection-oriented TCP.In the data packets to be transported, there is a RTP header that contains some important information such as the data sequence numbers and timestamps, Timestamp is the description of the packet time synchronization information, it helps the critical data be restored to the correct chronological order, which requires that the sender timestamps increase continuously and monotonically. So that at the receiving end, as long as a certain data cached, the video data can be sorted and restored in accordance with the normal sequence.According to the size of the receive buffer, using the RTP transmission will bring a little certain delay, but a certain improvement in image quality at the same time, which doesn't influence the real-time.RTP and UDP are point-to-point transmission, in order to meet some one-to-many transmission requirements, the system also implements RTSP (the Real Time Streaming Protocol) protocol stack with the Client (decoder) / Server (encoder) model, it's a text-based protocol for client and server to establish and negotiate the real-time streaming.RTSP is also an application layer protocol, which is located above RTP. This protocol doesn’t transmit the data, it only control the states of the stream. The system still uses the RTP/UDP to transmit the stream at the transport layer.VI. E XPERIMENTSThe design described in this paper is successfully used in a opto-electronic system, Fig.3 shows the bitrate curve in the corresponding experiments.We set the video bitrate of 6000kb/s, the long term rate is stable. In the static scene, the bitrate is about 5000kb/s, especially in some low complexity scene, the rate is below 4000kb/s; in the motion scene in a short while, the rate increases to 6000kb/s.The whole latency is about 300ms, when the videodisplays in the remote decoder.Figure 3. The Bitrate changes.VII. C ONCLUSIONThe paper designs a real-time full HD video communication system which combined FPGA and SOC, and then introduces in detail the design of each module including BT.1120 Stream conversion, low latency rate control and network transmission. The result shows that the system has the following advantages. One is high real time, the H.264 codec can encode the video at high speed with the low latency rate control algorithm. The other one, the FPGA have rich resources inside, and can achieve the required functions on different demands.R EFERENCES[1] W. Chen, P. Chen, W. Lee and C.

位置: 接主板上. 通过主板USB、PCI、1394、网卡等组件接口与视频捕捉设备(USB摄像头\数码相机\视频采集卡等等) 直接或间接连接,以获取视频源数据
功能: 提供一个接口或插槽, 以兼容不同厂家品牌的视频硬件设备, 一般都需要硬件驱动
其他:
系统设备
名称: 图像处理设备
位置: 视频硬件驱动安装后, 出现在”设备管理器”中”图像处理设备”子树下, 视频捕捉设备(fme)可以识别捕捉到的系统硬件
功能: 包装不同类型硬件驱动层,以使fme可以识别的软件, 可以屏蔽了不同类型硬件驱动成OS标准接口
注意: 有可能需要自己提供一层软件包装, 以解决fme不可识别的情况,

视频数据收集程序
名称: flash media encoding 2.5
位置: 需安装
功能: 收集视频源数据, 编码成fms可以识别种类的视频流, 并发往”视频服务器”对应的流频道上, 供client的flash访问
右侧Stream to Flash Media Server 页，主要功能：设置编码后发送的目的地属性
1、FMS URL属性，设置去向地址，格式: http://IP地址:端口/频道
2、Stream属性，在FMS URL的去向地址上新建一个流。
使用: 配置完成后,需先启动fms服务和fms admin服务, 再启动fme右侧的连接,最后启动编码服务, 完成后可以在fms里看到多个数据输入的客户端.
WEB容器
名称: tomcat6.0以上
位置: 安装或绿色版, 安装版需要启动tomcat服务
功能: 网站程序运行环境, 提供客户端访问. IE访问时,除了实时视频部分,其他数据均与”web容器”交互通讯.
视频服务器
配置: 配置极好性能极佳的服务器. Client数量小,视频数据极少时,可用”单板电脑’充当硬件要求: CPU: 2.0G , 内存: 4G, 硬盘空间: 如果需要保存实时数据,空间要求比较大
视频软件
程序名称: Adobe Flash Media Server 3.0.1(开发版)
功能: 存放视频服务器软件—Flash Media Server程序, 属Adobe公司产品, 用来设置处理多路客户端和多服务器及边缘服务器的程序, 接收”视频数据收集进程”发送过来的数据. 它是整个视频方案的核心.
安全认证: 在线视频频道可以进行一些简单的配置编程, 用于验证flash客户端, 拒绝非法连接, 保护服务器性能
支持系统: winXP,win2003及以上版, linux--RED4 5以上版(文档介绍支持, 但未试验测试), 经过虚拟机测试: win2K不支持
