A streaming media publishing system and method for use in delivering streaming media to personal computers. The streaming media publishing system and method preferably delivers streaming media content by way of a broadband satellite-based communications network. A content processing center receives media content in analog. digital and textual formats from a content provider or corporation. The media content is processed at the content processing center to produce a streaming media presentation. The streaming media presentation comprises a video and audio stream that includes searchable metadata that is integrated with HTML web pages. The content processing center communicates by way of a satellite or terrestrial linkwith a cache server that stores the streaming media presentation. The streaming media presentation displayed on the client personal computers using web browser software and by selecting an thumbnail representative of the presentation. The metadata may be searched to allow a user to jump to the a particular word in the presentation. Words contained in each HTML page may be indexed to permit searching based upon the use of &#x3c;meta&#x3e; tag placed in headers of each HTML page. Markers may also be placed in the video that allow users to jump to various points in the presentation.

Streaming media publishing system and method

Low-cost, high performance access is provided to an Internet service provider (ISP) not convenient to a high volume Internet exchange point using a flexible hybrid terrestrial-satellite Internet communications system and method. The system and method provide high volume connectivity between an Internet service provider (ISP) and a remote customer site that generates a request for content to be supplied by the ISP. In an exemplary system, a first gateway processes a request for content generated at the remote customer site and routes the request. A second gateway processes the request routed by the first gateway to route the request to the content provider. One or more satellites are used to transmit requested content supplied by the ISP to the remote customer site. An exemplary method comprises the steps of generating a request for content at the remote customer site, processing the request for content to route it to the content provider, and transmitting requested content supplied by the ISP to the remote customer site by way of one or more satellites. The request for content may be routed by way of a terrestrial communications link, such the Internet, or may be routed to the ISP by way of the one or more satellites. The transmitted content may be received directly at the remote customer site, or routed to the remote customer site by way of a gateway or other point of presence (pop) site.

Internet communication system and method with asymmetric terrestrial and satellite links

Low-cost, high performance access is provided to a group of Internet service providers (ISPs) not convenient to a high volume Internet exchange point through a flexible hybrid terrestrial-satellite Internet communication system. Asymmetric hybrid circuits, that combine satellite and terrestrial backbone technologies, are used to handle asymmetry resulting from low volume requests and high volume responses. A user request is coupled via routers and servers to a point of presence (POP) on a group ISP backbone network. The ISP's backbone couples ISP's POPs to a terrestrial gateway location, which is coupled to a high volume ISP peered with other high volume ISPs. Requests are directed to the high volume ISP through a POP on the backbone of the high volume ISP. Responses from the high volume ISP are routed to a hybrid network provider. Responses packets are translated into permanent virtual circuits (PVC) by a router. The high volume ISP is instructed to advertise response packets with high priority and reference toward the satellite uplink. Response packets are transferred to the group ISP or ISPs based on the type of transmitted information. In the hybrid network provider POP, switch devices impose a committed information rate on each PVC, which has a guaranteed minimum bandwidth for its associated PVC. The hybrid network provider POP delivers the PVCs to the satellite link, which transmits signals incorporating all the transmitted PVCs via satellite and satellite downlink to each group ISP. Routers coupled to each POP of each such ISP, filter the received PVCs so that responses are delivered to the closed POP to the location of a corresponding request.
