Abstract

A method for employing a Hypertext Transfer Protocol (HTTP protocol) for transmitting streamed digital media data from a server. The server is configured for coupling to a client computer via a computer network. The method includes receiving at the server from the client an HTTP POST request. The POST request requests a first portion of the digital media data and includes a request header and a request entity-body. The request entity body includes a media command for causing the first portion of the digital media data to be sent from the server to the client. The method further includes sending an HTTP response to the client from the server. The HTTP response includes a response header and a response entity body. The response entity body includes at least a portion of the first portion of the digital media data.
