Gong一、多媒体教室建设方案综述1、方案整体描述人类正阔步进入网络化和信息化社会，这是人才竞争的时代，是追求高效率优化创新的时代。国家一直在重点强调：实施素质教育，充分发挥现代教育技术的作用，大力提高教育技术手段的现代化水平和教育信息化程度。近年来，数字化校园网建设日趋完善，并逐步装备了现代多媒体教学设备和相应的教学系统，为实施素质教育提供了新的视野和前景，提供了有力的技术支持。传统的教学以教育者为中心，以传授知识为主。老师与老师之间、老师与学校之间互动不够，资源孤立，教师资源、校本资源浪费严重。设备冗余、分散，管理不便。而以信息技术为代表的现代化教育技术的应用则表现出明显的先进性、灵活性、可靠性、开放性。现代教育技术是运用现代教育理论和现代信息技术，通过对教学过程和教学资源的设计、开发、应用、评价和管理，以实现教学过程和教学资源的优化的理论和实践。它的内涵包括：一是现代教育技术的目的是实现教育最优化；二是现代教育技术设计的不仅是计算机、网络等现代教育媒体，而是教育过程所有可操作的要素，包括人力资源和技术资源，如教学人员、校本资源、常规教学媒体、教学设施、教学活动等。将校园网从普通计算机局域网建设成为面向教学、科研、管理等应用的网络，能够传输和处理多媒体信息，使各种类型的多媒体资源能在校园网上灵活应用，并且能一网多用，多网合一，将众多校园独立的应用系统整合起来，是校园网解决方案的发展方向。网络化多媒体教室就是以现代教育为目的，涵盖了以上所有要素的专业解决方案。在多媒体教室建设过程中，综合应用了计算机技术和多媒体技术及控制技术，集中协同控制计算机、影碟机、录像机、视频展台、投影机等现代视听设备，同时对电动窗帘、灯光、幕布等环境设备进行集中控制，通过大屏幕投影，营造出一个高精度大屏幕显示、高保真音质、受控声光背景的现代化多媒体视听教学环境。当前，很多高校的传统多媒体教室和基础校园网建设已相继完成。随着多媒体、计算机、网络等高新技术的飞速发展，多媒体教室建设需求不断发展，出现许多新的特性，逐渐的从单纯的设备控制变成基于网络的教学管的综合应用，对新兴的网络化多媒体教室建设提出了新的要求。2、从功能应用方面分析：1) 多媒体教室的网络化集中管理、控制和维护；对于多媒体教室，高校要求可管理性不断提高，可管理的范围不断扩大，使多媒体教室纳入有序化管理；同时，对于多媒体教室的控制力度加强，维护更加简易化，从设备配置、基础信息、状态报告、统计分析、远程调试、远程协助、远程升级等多方面实现控制。2) 多媒体教室实现可视化管理，全面扩展安全防盗系统；多媒体教室引入数字视频系统，实现可视化管理，提高管理效率；同时，系统要实现复用，配合电子锁、门磁、红外感应器、双鉴探测器等前端设备在特定时段实现安全防盗应用，这样，对于多媒体教室的核心设备中控的全天候工作能力提出了更高的要求。3) 多媒体主播教室及课堂录播系统的建设；在多媒体教室环境下，通过合理的扩展，采用先进高效的VGA采编技术，将主播教室多媒体课件内容和多路教学现况实时采编，传输，广播，点播，编辑等功能，实现优质课堂全方位、立体化再现，有效开展精品课程建设。4) 系统整合，实现综合应用；实现校园网、多媒体教室和数字化资源合理整合，实现基于多媒体教室环境下的教学管的综合应用。实现数字视音频直播功能、数字监控功能、IP电话功能、VOD、AOD、COD等多媒体教学功能；3、从系统性能方面分析：1) 多媒体教室的管理核心中控设备的稳定性；中控功能越来越强大，已经成为多媒体教室的管理核心，大部分的管理工作都依靠中控来实现，因此对中控工作的性能要求就很高，尤其是稳定性，需要从基础技术、工艺结构、设计开发、人机界面等多方面进行解决。2) 中控全天候工作的能力；可视化管理成为多媒体教室建设的必然趋势，可视化的一个重要应用就是安全防盗，整个中控系统不仅要满足教学时段的应用，还要满足非教学时段的应用，这就要求整个管理的核心中控要具备极佳的全天候不间断的工作能力。3) 中控管理的灵活性和定制性；由于教学方式和管理方式的差异，不同学校在多媒体教室的建设标准、应用标准和管理标准都是不一样，这就要求基于中控为核心的多媒体教室建设要灵活，整体规划，模块化搭建，管理模式可定制，以最适合学校用户需求的标准自主创建多媒体教室的建设和管理应用。4) 设备操作的简便性；操作的简便性是系统应用的基本特性，充分体现友好的人机交互和系统的人性化。4、方案设计思路多媒体教室建设方案是一个多种应用、多种设备整合的一个应用方案，这其中的核心就是中控，中控的技术架构就决定了整个多媒体教室建设的模式、特点和应用。高校多媒体教室已发展多年，目前，多媒体教室的建设已经从单纯的设备控制变成了基于网络环境的教学管的综合应用，这就对核心设备中控的功能扩展和性能提出了更高的要求。A、这些要求从功能方面分析有：1) 多媒体教室的网络化集中管理、控制和维护；2) 多媒体教室实现可视化管理，全面扩展安全防盗系统；3) 多媒体主播教室及课堂录播系统的建设；4) 系统整合，实现综合应用；B、从性能方面分析有：1) 多媒体教室的管理核心中控设备的稳定性；2) 中控全天候工作的能力；3) 中控管理的灵活性和定制性；4) 设备操作的简便性；为了满足这些需求，目前在中控领域主要有三种主流的技术架构：单片机架构、PC机架构、嵌入式架构。单片机架构在中控领域发展时间比较长，稳定性较好，但面临基于网络环境的教学管的综合应用比较大的问题就是扩展性；PC机架构刚刚开始进入中控领域，比较好的解决了基于网络环境的教学管的综合应用，但PC架构的特性使中控的稳定性、全天候工作能力方面产生了严重问题。采用嵌入式架构可以充分发挥以上两种技术架构的优点，屏蔽缺点，具体的思路有：1) 嵌入式平台低功耗、发热小、稳定性高；2) 嵌入式Linux操作系统高效稳定；3) ARM9平台运算能力强，接口丰富，扩展性强；4) 开放式结构，实现用户管理控制自定义，体现定制性；5) 功能定义准确明晰，模块化搭建，体现灵活性；6) 人机界面友好，体现简便性；7) 配合强大完整的C/S、B/S后台软件，全面提升多媒体教室应用。5、多媒体教室功能建设需求分析A、多媒体教室管理系统1) 本地/远程信号切换、设备开关、幕布升降、音量调节等基本控制；2) 钢制讲台、投影机、计算机的本地/远程开启/关闭；3) 多层次树形结构，灵活分级、分类查看；4) 所有教室状态、设备状态的远程监看和管理；5) 课表自动导入，课表开关机；6) 多种形式的定时管理；7) 日志记录及统计分析管理，以报表形式输出，提交打印；8) 用户及权限管理；9) 本地调试设置，B/S结构远程设置、维护、升级，远程WEB管理界面；10) IC 卡管理（接触式、感应式），门禁系统联动、校园一卡通系统整合；11) IC卡刷卡，PC机软件客户端自动登陆；12) 控制自定义，实现基本控制、组合控制等的随意定制；B、视频监控系统1) 多画面集中监看，自动或手动巡视，远程云台镜头控制；2) 数字电视墙集中监看，灵活布局，集中管理；3) 手动或定时录像，集中管理，分布存储；4) 录像资料管理，加密、抓拍、截取、回放等；5) 三层体系的电子监考系统，城域网、广域网平台整合；6) 移动侦测，自动录像；7) 教学评估，微格评测系统；8) 教学示范，广播、现场直播。C、安防报警系统1) 红外灯、探测器、双鉴等触发报警；2) 电子锁远程开启/关闭；3) 门磁报警；4) 断线报警（投影机线、摄像机视频丢失报警等等）；5) 移动侦测报警；6) 本地和远程触发声光报警。7) IC非法刷卡报警（非法用户、非允许时段等）D、课堂录播系统1) 多路音视频、VGA信号同步采集、编码、压缩、传输；2) 所见即所录，VGA信号采编自适应（分辨率、刷新率），不同的VGA信号源（PC机、笔记本、展台）任意切换也可轻松采编；3) 课堂直播，多路视频流同步直播，任意切换控制；4) 课堂录制，多流合一，生成一个或多个标准AVI文件，便于后期编辑；5) 资料编辑，添加标题、索引、背景资料，裁减，提供通用播放平台界面等；6) 离线课堂，资源可以生成网页或DVD格式，便于传播；7) 课堂录制资源自动导入资源管理平台。E、多媒体教学系统1) B/S或C/S架构的VOD、AOD、COD资源点播；2) U盘资源点播，远程接管电脑的点播方式；3) 模拟音视频资源、闭路电视点播；4) B/S架构的资源管理平台，提供上传、检索、自动导入、批量导入等应用，学校和家庭的建设模式；5) 互动课堂，视频会议；6) 音视频资源广播、本地音、视频广播、课件广播、字幕广播、精品课程广播等。F、IP电话通讯系统1) 教室和主控室之间语音通讯，可视通讯；2) 即插即用；3) 手动拨号、快速拨号、缩位拨号等；4) 教室通过IP电话呼叫网络中心，网管软件自动弹出控制、监控界面；H、PC机远程管理维护系统1) PC机远程开关机；2) PC信息远程读取，硬件配置和软件信息；3) PC机远程状态报告，CPU、硬盘、温度等；4) PC机远程接管，远程协助；5) VHD计算机管理系统，远程备份，远程恢复，双模式启动；I、资产管理系统1) PC机的配置硬件（包括显卡、CPU、内存、硬盘等）信息统计；2) 投影机灯泡计时信息统计；3) 其他设备配置及使用信息统计；4) 统计信息形成并输出资产报表（Excel格式）。J、扩声投影等外部系统1) 根据教室布局合理选择投影机亮度及幕布大小；2) 投影机专用吊箱，提供安全防盗和高效散热；3) 扩声系统的选择（数字功放模块、普通扩声、移频扩声等）；4) 灯光系统的设计；二、录播系统方案综述1、方案整体描述精品课程录播系统解决的问题就是把一些非常优质的教育资源通过现代化的教学手段，得到共享。而传统的教学以教育者为中心，以传授知识为主。老师与老师之间、老师与学生之间互动不够，资源孤立，教师资源、校本资源浪费严重。而以信息技术为代表的现代化教育技术的应用则表现出明显的先进性、灵活性、可靠性、开放性。现代教育技术，是运用现代教育理论和现代信息技术，通过对教学过程和教学资源的设计、开发、应用、评价和管理，以实现教学过程和教学资源的优化的理论和实践。它的内涵包括：一是现代教育技术的目的是实现教育最优化；二是现代教育技术设计的不仅是计算机、网络等现代教育媒体，而是教育过程所有可操作的要素，包括人力资源和技术资源，如教学人员、校本资源、常规教学媒体、教学设施、教学活动等。将校园网从普通计算机局域网建设成为面向教学、科研、管理等应用的网络，能够传输和处理多媒体信息，使各种类型的多媒体资源能在校园网上灵活应用，并且能一网多用，多网合一，将众多校园独立的应用系统整合起来，是校园网解决方案的发展方向。精品课程录播系统：针对现今高校信息化教学的重点需求，利用纯硬件的VGA采集压缩编码技术实现老师的讲稿、多媒体课件、现场多路的音视频信号实时采集压缩，以标准的流媒体方式实现在网络中的传输、管理、控制，支持网络的点播、广播、直播、存贮、后期编辑等多种利用。2、系统背景介绍从1999年起，校园信息化建设开始兴起，局域网、城域网、计算机教室等热潮不断兴起。技术上的创新与进步，客观上能推动教学辅助手段的进步。进入21世纪，随着PC记、笔记本类设备不断普及，师生对计算机类设备的操作应用水平不断提高。同时，网络技术的发展对教育最大的影响就是网络教育的兴起，网络技术使用得物理、空间上的距离不断缩小，使得优质教学资源能让更多的师生共享。共享优质教学资源，实现公平教育，力推网上自主学习，使得精品课程建设就成为一种新的潮流。从精品课程建设发展的过程来看，最早是从高校开始兴起。教育部关于精品课建设的要求及政策，极大地推动了相关设备与技术的发展。近两年，国内职业学习的实训教室以及普教中应用水平较高的中小学，也开始精品课程建设。最发展的趋势来看，精品课程建设正在不断深入发展之中，其发展前景广阔。3、系统应用范围1、精品课程课件、网络课件制作系统能自动生成精品课程课件，并可生成可供网络点播的网络课件，后期可对录像文件进行删减、合成、索引等编辑，也可导入非线编平台进行专业编辑。方便用户教与学的综合应用，优质精品课件的评比等等。2、精品课资源库建设可以为学校进行精品课程资源库建设，同时也可为课件上传提供开放式管理平台。教师上课完，录制的课件自动生成后，上传到服务器；配合个人资源库管理权限，进行资源分类/多级目录创建/课件预览/课件删除等操作。系统还提供B/S和C/S两种结构的资源管理平台，为教师资源上传点播提供开放式管理平台。同时管理平台全面支持基于内部园区网或广域网终端对课件库资源的授权访问/浏览查询/下载导出应用。3、远程教学应用随着网络技术的运用普及，学校也从单纯的教室课堂发展到了与网络课堂相结合的多模式教学活动。通过录播系统，用户可以进行课件的网络直播和课后点播，示范性教学、学生远程学习，远程互动教学等等。用户可以随时随地进行观摩、学习，不再受空间和时间的限制。4、教学技能训练教师的教学技能训练一直是学校关注的重点，以往通过上教室现场听课的方式无法正确客观地对教师进行评估，已经无法满足学校的需求。结合学校的需求，根据微格教学的特点，在录播系统中嵌入微格教学评估系统，学校通过系统内的各项技术指标进行评测评估（技术指标内容可根据学校实际情况进行修改），通过远程对教师的教学技能进行客观的综合评估，以训练教师的各项教学技能，从而使教学水平得以提高。5、校园电视台由于精品课堂录播教室是一个专业的演播教室，扩音、拾音、灯光、等各系统的配置均达到了专业演播要求，因此，学校也可以把精品课堂录播教室做为校园电视台利用。企事业单位培训、专家报告、重要会议录制在企事业单位里，各种培训、专家的报告、重要的会议越来越多，随着信息技术数字化、网络化进程的不断深入，各种如手工记录、人工录音和人工录像的原始模式已经无法满足需求，通过录播系统进行全方位的录制，真实地记录各种会议的全过程，并作为历史资料永久保存下来，可以方便用户在会后进行资料查询和播放
