Streaming Media Protocols
Online video websites like YouTube, Google Video, MySpace, Yahoo video etc are using streaming technology to sharing and delivering videos.
With Streaming Video Recorder, You can download streaming videos from these websites.
Here is something about Streaming Media Protocols:
Streaming Media Protocols: HTTP streaming
Hypertext Transfer Protocol (HTTP) is a communications protocol. Its use for retrieving inter-linked text documents (hypertext) led to the establishment of the World Wide Web. HTTP Streaming is achieved through several common mechanisms.
In one such mechanism the web server does not terminate the response to the client after data has been served. This differs from the typical HTTP cycle in which the response is closed immediately following data transmission. The web server leaves the response open such that if an event is received, it can immediately be sent to the client. Otherwise the data would have to be queued until the client’s next request is made to the web server. The act of repeatedly queing and re-requesting information is known as a Polling mechanism.
Typical uses for HTTP Streaming include market data distribution (stock tickers), live chat/messaging systems, online betting and gaming, sport results, monitoring consoles and Sensor network monitoring.
Streaming Media Protocols: MMS (Microsoft Media Services)
Microsoft’s streaming server uses the Microsoft Media Services (MMS) protocol (also called NetShow Services) to transfer unicast data. MMS can be transported via UDP or TCP. If the Windows Media Player client cannot negotiate a good connection using MMS over UDP, it will resort to MMS over TCP. If that fails, the connection can be made using a modified version of HTTP (always over TCP). This is not as ideal for streaming as MMS over UDP, but ensures connectivity nonetheless.
The default port for MMS is 1755.
Streaming Media Protocols: RTSP
The Real Time Streaming Protocol (RTSP), developed by the IETF and published in 1998 as RFC 2326, is a protocol for use in streaming media systems which allows a client to remotely control a streaming media server, issuing VCR-like commands such as “play” and “pause”, and allowing time-based access to files on a server.
Some RTSP servers use RTP as the transport protocol for the actual audio/video data. Many RTSP servers use RealNetworks’s proprietary RDT as the transport protocol.
Streaming Media Protocols: RTMP
Real Time Messaging Protocol (RTMP) Is a proprietary protocol developed by Adobe Systems (formerly developed by Macromedia) that is primarily used with Macromedia Flash Media Server to stream audio and video over the internet to the Adobe Flash Player client.
The default connection port is 1935.
