    • 1.4 References 1.4.1 Software engineering (the production of quality software), second edition, Shari Lawrence. 1.4.2 System analysis document. 1.4.3 IEEE recommended practice for software requirements specification 1.4.4 World Wide Web (internet). 1.4.5 University guide and our supervisor. 1.4.6 Hebron radio member. 1.5Overview. We describe in the previous sections most of things will help us to continue with documentations and we will do the rest of and making overall description and specific requirements of the web application of the Hebron radio in the next two chapters 2- Overall description. Here we describe the general factors that affect the product and requirements .here we want to provide a background for requirements of the Hebron radio and make them easier to understand by the designers and programmers of the system. This part contains the following subsection: 2.1 Product perspective. 2.2 Product function.
    • 2.3 User characteristics. 2.4 Constraints 2.5 Assumption and dependencies. 2.6 Requirements subset. 2.1 Product perspective. The web application of Hebron radio we want to build is depended on the user and the administrator who control all the work in this sit, and here we describe the following: 2.1.1 System interface. 2.1.2 User interfaces 2.1.3 Hardware interface. 2.1.4 Software interface. 2.1.6 Memory constraints. 2.1.7 Operations. 2.1.1 System interface The system interface will made according to PHP product and it will be complete and here there is need to other software which is the dream waver and MYSQL and the most important software which I needed in this web is the media server which I explain about it in brief:
    • What is media server? • It is exactly like a web server that can add capabilities to any Web site, such as offering radio and television programs that use ASF format. • Advanced Streaming Format (ASF) A data format for streaming audio and video content, images, and script commands in packets over a network. ASF content can be an .asf file or a live stream generated by Windows Media Encoder. ASF content that is in the process of being delivered over a network is called an ASF stream. WINDOW MEDIA PLAYER TOOLS COMPUTER 1-windows media tools can create /asf files 2-windows media tools can create as a file 3-windows media encoder can driver a live stream to a windows media server to be served as a unicast and a multicast contact. 4-windows media server can use .asf files as a source for unicast or multicast content. 5-windows media server cans unicast content to a client. 6-windows media server cans multicast content over an IP address.
    • Why we use media server? 1. Windows Media Services offers the ability to provide multimedia content to a large number of clients using ASF.Wma .MP3 and .wav formats. 2. Each client can render content as it is being received over the network without downloading the content first due to the use of data streaming
    • 3. Permits presentations of unlimited length, as well as live broadcasts. 4 media server use. ASF format for streaming. This is the better than .wav or .MP3 files, because if it’s used this format the performance can be significantly affected. Also, features such as adding images and script commands are not available. 5. Windows Media Services is a product that can be used to provide content to both Internet and intranet users 1- unicast content can be accessed by a term publishing point which is a virtual directory that stores content you have made available to clients on your server 2- multicast 3- A multicast is a content stream delivered over a multicast-enabled network all clients on the network share the same stream. The biggest advantage of streaming ASF content in this manner is that it saves network bandwidth 4- Multicast content can be accessed by a term station point which is consists of at least one program and stream
    • Windows Media Services protocols • The following diagram depicts how protocols are used to communicate between the components (Windows Media component services and Windows Media Administrator. )Of a Windows Media Services system.
    • Windows Media Encoder is the tool of choice when: 1- You are using a live source. 2- You need to compress the video source (live or stored) so that the resulting ASF stream or .asf file fits in a target bandwidth 3- You want to create content that can span several target bandwidths. 4- You are converting content from an .avi, .mp3, or .wav file, and you want to use a different codec or select the size of the video display. You can run Windows Media Administrator on:- 1- Microsoft Windows 2000 Server. 2- Microsoft Windows 2000 Professional, Microsoft Windows 98, or Microsoft Windows NT 4 with Service Pack 4 (SP4) or later. 3- It is possible to run Windows Media Administrator in Internet Explorer 4.01, or on Microsoft Windows 95, but these are not supported platforms. • Unreal media server Is a Streaming Server for Windows operating systems, that dares to compete with mentioned servers from the standpoint of quality and performance.
    • • File types Both media files and live media streams are supported. File types include all the types playable by MS DirectShow, namely: AVI, MPEG-1, MPEG-2, MPA, WMV, WMA, ASF, MP3, QuickTime (version 2 and lower). • Protocols:- TCP and HTTP transport protocols are used for streaming content from Media Server to clients. Incoming content is not stored on client computer's hard disk and user is not allowed to save media locally, thus author's rights are fully protected. • Installation and configuration 1. Media Server and Client. After you have downloaded and run the installation program for Unreal Media Server, the service called UMediaServer should be running and listening on TCP port 5119. If you have Microsoft IIS running on the computer, then it is suggested to install IIS extension for streaming (UHTTPProxy). During the installation please do not change the name of the virtual folder. After the installation please make sure that the IIS virtual folder
    • UHTTPProxy allows anonymous access. When you have installed IIS extension for streaming, the Media Server will be able to stream media content via HTTP. The installation program sets up a sample video clip by creating a virtual folder called Media Root (this is not IIS folder, but Media Server's one), mapping this folder to the program installation directory ("Program FilesUnreal StreamingMedia Root" by default) and placing file "test.avi" in latter directory. • Streaming Media Player Needs to be installed in order to see streaming media. Start the player and enter IP address or machine name of the Media Server computer. If you choose TCP as a transport protocol, make sure there are no firewalls between client and server machines that block port 5119. If this particular port is blocked, use Media Server Configuration tool, which is a part of Media Server installation, to change this port number. If all TCP traffic is blocked, your only choice is to connect via HTTP. Once the client computer can reach the server computer, you should be able to stream the test file. Using Media Server Configuration tool, you can create virtual folders and map them to the different physical locations on the server machine.
    • Alternatively, the physical location can be anywhere in the server machine's LAN. To make this work, several steps should be done. • Win 2000: You will need to map network drive, such that the remote folder will be treated as a local folder. Win XP: Browse to network folder. • The security should be setup such that the account, under which UMediaServer runs, has access to this network drive. By default, UMediaServer runs under local system account. You will need to have an account that can access this network drive, and make UMediaServer service run under this account. Use "control panel - services - UMediaServer properties" to change the account. Once virtual folder is accessible by Media Server, the files in this folder can be streamed to the clients. Users will need to specify this folder in Streaming Media Player. Virtual folder can be configured to require internal or session-based authentication. • Live Source Server • Live source server should be installed on the computer that has live media sources attached to it. Live media sources include: digital cameras, microphones, analog video sources (analog camera or TV) connected to Video card or to Frame Grabber card that supports DirectShow
    • interface. There can be multiple live sources attached to a single computer. Download and run the installation program for Unreal Live Server . The service called ULiveServer should be running and listening on TCP port 5120. It's very important to understand that the requests to this server will be coming from Media Server computer, not from the client computers. Therefore Live Server machine should be reachable from Media Server machine. The request from Media Server to Live Server can only be made by TCP via port 5120. Use Live Server configuration tool to add and configure a source for your live media content, such as camera/microphone/other. You can also configure access restrictions based on Media Server. • IP addresses. The clients should be able to see live source, provided they know the IP address/machine name of Live Server and Media Server machines, and the media source ID. Using Media Server Configuration tool, you can create aliases for live sources. Clients can then use the alias to get live stream.
    • • Creating a link to media resource The most comfortable way for the users to access remote media is to click on a link in the Web browser. Setup of Streaming Media Player registers a custom URL protocol on user's machine. This is a UMS protocol, allowing launching Streaming Media Player directly from the hyperlink on the Web page. The person, who configures the Media Server, is responsible for creation of these links and putting them to the web pages. The link can refer only to File or Alias of the live source. Direct access to the live source is not allowed in the link. Link should consist of 4 parts: 1. "ums:" or "ums://". 2. Transport protocol followed by semicolon - TCP or HTTP. 3. Media Server IP address followed by backslash. If no port is specified, default port corresponding to the transport protocol will be used for the connection. Default TCP port is 5119, default HTTP port is 80. 4. Actual media name. In no slash or backslash is found in the name, the name will be treated as the Alias of the live source. Otherwise the name will be treated as a filename.
    • The hyperlink on the web page might look like this: <A HREF="ums:TCP:65.68.17.44:5127MediaMyfile.avi">Myfil e.avi</A>. Or like this: < A HREF="ums:HTTP:207.68.171.244MyWebCam">My Web Camera</A>. The part shown in brown color is the actual link. This link can alternatively be used on the local user's machine in two ways: Passing it as a parameter to Streaming media player: StreamingMediaPlayer.exe ums:TCP:65.68.17.44:5127Media Myfile.avi Running the link alone: ums:TCP:65.68.17.44:5127Media Myfile.avi in all the described cases streaming media player will launch and start playing the remote media. • Media Server's advantages: We stream any type of multimedia file; therefore you don't need to re-encode your existing files. Our live server compresses video in real-time using one-pass MPEG-4 codec. Therefore the delay from the real time on the client is minimal - less than a couple of seconds. Using Microsoft's
    • server, you never get delay less than 8 seconds, typically it is much bigger. This is because they use two-pass WMV codec to encode video. Only 10 clients can simultaneously get video streams from the server via HTTP: Internet Information Server (IIS) running on Windows 2000 Professional or XP is limited to work with only 10 concurrent clients. This is hard coded in IIS by Microsoft and cannot be changed. If there will be many clients connected via HTTP, then it's recommended to install Unreal Media Server on Windows 2000 or 2003 server platform. Does Unreal Media Server support Multicast protocol? No, it doesn't. However, the way Media Server works is very similar to IP multicasting. When many clients view the same live stream simultaneously, Media Server receives only a single stream from Live Server computer, and distributes this stream to the clients. Thus, the traffic between Media Server computer and live server computer doesn't depend on the number of active clients. 2.1.2 User interfaces.
    • The web application of Hebron radio will be used by several user (we will describe them in the section among this document) Each of them used and works with the part of the system and need some interface about the work. We have the admin page this page just seen by the administrator and just control by administrator (with privilege his user name and password). And we have the user page .this page user can enter to it and make the allowing operation that allow to you. That is discussing in the next chapter. 2.1.3 Hard ware interface.
