Progressive Streaming of Video And Audio Over Http

ABSTRACT

Implementing low cost Progressive Streaming of Video & Audio over HTTP protocol. Main aim of this solution is to capture, send and play the video of conference through HTTP.
Real-time streaming of media allows users to play media as they receive it. Users don't have to wait for the whole media file to be downloaded before watching. To enable real-time streaming, dedicated streaming media servers and streaming protocols, such as Real Time Protocol (RTP), are required. RTP is an Internet standard for transporting real-time data. It uses the unreliable UDP protocol to transmit packets.
A variant of real-time streaming is progressive streaming, also called HTTP streaming because it uses the commonly used HTTP protocol and standard HTTP servers to deliver media files. Progressive streaming enables files to be watched as they are downloaded. When the client makes a request (HTTP) to the server for the media file, the file eventually gets stored in the client's memory buffer. The playback is allowed before the entire file gets downloaded. Most firewalls allow traffic over HTTP whereas RTP is not permitted by most firewalls. In our approach, we're emulating HTTP streaming. In this we are using JMF to capture the media file.
