ABSTRACT:

TECHNICAL FIELD
The present invention relates to the transportation of data from a content node to a presentation node on a network, and particularly to the presentation of audio and video information on a selected network node which is presented at a user node with assistance from a media content server.
BACKGROUND OF THE INVENTION
Video or audio content presented to a user on a web browser may be in content documents and pages received from a media server, e.g., a video or audio server. The web browser may contain, or receive by downloading, a plug-in which is configured to play real-time audio or real-time video (respectively “streaming or real-time audio or video”) in cooperation with streaming data from an external video or audio server. The video or audio plug-in is installed on a client machine and includes code which opens a predetermined window in the browser within which the video content is played and viewable.
Unfortunately, the content provider often has no control over the amount of content usage by a user nor over the replication of this content. Accordingly, there is a need to control content presentation and reproduction by unauthorized and unauthenticated users of media content distributed over networks, including but not limited to the Internet.
In particular, there is a desire to ensure that content is sourced from the original content producer or maker at an initial URL, rather than allowing secondary sourcing from intermediate distributors who may undesirably modify the original content, or undesirably strip off ancillary content such as advertising material for example, or who may not charge the user. Thus, it would be desirable to encourage the user to view or receive only originally constituted content.
SUMMARY OF THE INVENTION
According to the present invention, the uniform resource locator (URL) code associated with a page provided by a world wide web server to a user is stored and provided to a media server which maintains a data base of documents and corresponding authorized URL profiles. When a user requests real-time presentation of selected media content, the user communicates the document name and URL prefix to the media server cooperating in user presentation of the selected content for authentication. If it is determined that there is no authorized correspondence with the indicated URL prefix and the document name provided, then the user node is notified that the requested presentation is unauthorized.
According to one embodiment of the present invention, the user is provided with the correct URL prefix to permit the user to communicate with the authorized content source directly, for example, to enable the user to download the document of interest from the authorized URL content provider for authorized viewing in cooperation with the selected media video server.
