Voice Server Aspiration Provide a unique service

Voice Server

Aspiration Provide a unique service to the members of CCSU. n Provide a Streaming Voice Server that can be used for storing presentations, public announcements, speeches, and conferences. n Members will be able to access this service for research and general knowledge purposes. n Collaborative effort to add something of value to the school community. n

Why is this topic interesting? n Allows us to combine our knowledge and experience learned from the school curriculum as well as from personal endeavors. n Provides a challenge to create a tangible device to be used by the college community.

Contributions n n n Providing the hardware and software needed to build the server test bed Installing operating system and Windows Media Services Troubleshooting of hardware and software Testing of server functions Documentation of steps needed to install Windows Media Services

Contributions (cont’d) n n n Verifying the implementation and settings of the IIS software Configuration of server services Troubleshooting of hardware and software Testing of server functions Design of web interface

Project Overview n Windows Media Services will be used in our project n Steps for a file to be streamed n Encode the file n Create a metafile with a windows extension n Adding tags to the HTML file so the user’s browser can recognize the streaming content

Project Overview (cont’d) n Streaming media files: n n Place any files that need to be available for streaming into the WMRoot folder Supported file types include: . asf, . wma, . wmv, . wm, . avi, . midi, . mpg, . mpeg, . mp 2, . mp 3, . aiff, . wav Non-supported file types: . ra, . rm, . ram, . mov, . qt, . mp 4 n IIS files: n Files for the website are stored in the Inetpub folder n

Windows Media Services Used in small businesses because it is cheaper n Simply embed the hyperlink file pointing to the file on the server into the website using special HTML coding n When the user clicks on the hyperlink, their media player opens and they can view or listen to the file n

Windows Media Services (cont’d) A program that comes with Windows Server 2003 n Handles streaming audio and video to users logging into the server n Live broadcasting, intelligent streaming (automatically adjusts to the users bit rate) n Web servers are not designed as well as WMS to handle streaming n Easy to configure because it is part of the OS n

Storage n By using an. mp 3 extension for an audio file, 1 minute of audio is typically compressed into 1 MB n By having a streaming server that just streams. mp 3 files, your server can have a 10 GB hard drive dedicated just to store the audio files and would provide the user with 10, 000 minutes of streaming audio to select from n Suggestion: Have your C: drive dedicated to holding the Operating System and core components of the system. Have a second hard drive just for storing the files to be streamed by the user

Storage (cont. ) n By using an. avi extension for a video file, 1 minute of video is typically compressed into 7 MB n Using a 10 GB hard drive on the server with just. avi files, the user can enjoy about 1, 430 minutes of video files n Decide what format the files on the server will be compressed in and calculate the space that will be needed

What have others used? n Real. Networks Helix Server n Linux, Windows Server 2000/2003, and Solaris n Apple Quick. Time Streaming Server n OSX Server n Apple Darwin Streaming Server (opensource) n OSX, Windows Server 2000/2003, and Red Hat 9 or above n Other Opensource servers: n GNUMP 3 d, Icecast, and Video. LAN

Future Considerations n Possibly add more software to server to make it more dynamic such as PHP n Add FTP services for downloading the file instead of streaming Collaborate with programmers to develop code to work with Firefox/Netscape-based browsers n Test server applications for security holes, i. e. IIS 6. 0, Windows Media Services, and Windows Server 2003 itself n

Conclusion We’ve learned how to setup the Windows Media Services on Server 2003 as well as integrating that service with IIS 6. 0. n Able to stream supported audio and video formats n Identified what issues there are with using a browser other than Internet Explorer n
