Second, I am intending on placing a HD TV capture card in my new Windows Sever PC, which currently shares through simple file sharing, all my media across my home network.
Clients use different methods to receive digital media content from Windows Media servers and Web servers: they stream digital media from a Windows Media server and download digital media from a Web server.
With the broader availability of high-bandwidth networks and new media delivery features for IIS 7 and above, the differences that previously favored the use of a Windows Media server over a Web server for delivering digital media content have blurred.
In non-multicast streaming scenarios, depending upon your business need, a Windows Media server or a Web server can both be viable options for digital media content delivery today. This article introduces the delivery methods and bandwidth-management capabilities of Windows Media servers and Web servers, two important aspects of media delivery to consider when you are trying to decide which server type to deploy for your delivery scenario.
This section introduces the two primary Windows Server roles that are used to deliver digital media to clients:. A Windows Media server is designed specifically for streaming on-demand and live digital media to clients. It is especially useful for streaming large amounts of data over busy, congested networks and low-bandwidth connections.
Streaming uses bandwidth more efficiently than downloading because it sends data over the network only at the speed that is necessary for the client to render it correctly. This helps prevent the network from becoming overloaded and helps maintain system reliability. Users that connect to a stream can start to play it almost immediately. If streaming on-demand content was indexed during encoding, they can use Seek functions Fast-Forward and Rewind on their player to jump to any part of the stream without waiting for a download to finish.
Streaming prevents users from downloading files directly to their hard disk because the streaming data packets are delivered directly to the client application and discarded by the client application after they are rendered. It also supports the use of JPEG files as media elements in server-side playlists or as banner graphics to be displayed in Windows Media Player. A Web server is designed to host Web sites and serve the Web site's pages and files to clients upon request.
When a client requests a file from a standard Web server, all available network bandwidth is used to download the data to the client as quickly as possible.
Web server deployments that serve small files to a limited number of users simultaneously require little bandwidth. But as delivery of audio and video files which are frequently large has increased, and as sites must serve greater numbers of simultaneous client requests, more bandwidth is required to fulfill the client requests in a timely manner. A Web server supports delivery of an unlimited number of popular digital media file formats using standard file-download.
User Datagram Protocol UDP has long been the preferred transport protocol for traditional streaming media. It is a fast, lightweight protocol without any retransmission or data-rate management functionality, making it an ideal protocol for transmitting real-time audio and video data, which can tolerate some lost packets.
UDP also has higher priority than Transmission Control Protocol TCP -based HTTP for Internet traffic, giving streaming audio and video data higher priority over file and Web page transfers and increasing the likelihood of uninterrupted viewing on congested networks.
A Windows Media server also uses UDP Resend, an intelligent UDP-retransmission scheme that ensures that it only retransmits lost packets that can be sent to a player in time to be played, instead of the blind retransmission scheme employed by TCP.
This smart-resend feature conserves additional bandwidth on congested networks. On networks that don't support UDP, the server is normally configured to use a process called protocol rollover to try TCP-based streaming, first by using RTSP, and if that doesn't work, it uses its own version of HTTP for firewalls that allow Web traffic through port This enables corporate users to view Internet content without compromising firewall security and ensures that all users on all networks can access all streaming media content.
As network bandwidths increase, the use of TCP is becoming more common. Because TCP guarantees delivery of every packet, it is preferred for video-on-demand delivery, especially if end users are paying for the content through a pay-per-view or subscription billing model. Fast Streaming. Fast Start and the newer Advanced Fast Start for WMS significantly reduce streaming buffering times to deliver near-television-like experiences when playing back content or switching between sources.
For on-demand content, Advanced Fast Start also enables quick seeking within a WMS stream, allowing users to "seek" forward or backward instantly. Included with Windows Media Services , this plug-in allows a Windows Media server in a branch office or other remote location to easily split a single broadcast stream from the home office into multiple streams for local end users, reducing WAN traffic.
Similarly, the caching functionality caches on-demand content streamed to the remote location e. Monetize Content. Cut Costs. Streaming for Windows Web Server Advertising for Streaming Content.
