A method and arrangement is provided for the multicasting of streaming digital content to a plurality of Internet users. Streaming digital audio, video or other digital data content that is to be multicast to Internet users is formatted into IP protocol at a head-end content source transmission site. The streaming IP digital data is transmitted from the head-end transmission site to at least one distant/remote routing station of an Internet service provider (i.e., a provider-edge router or Internet point of presence) via a bandwidth portion of a digital communications data transport service or transmission medium that is substantially unaffected by conventional Internet communications traffic. The Internet service provider (ISP) maintains at least one access router for providing Internet access via its Internet domain for its customers accessing the Internet via conventional two-way IP connection. The streaming IP digital data received from the content source transmission site by the ISP routing station may then be multicast via the IPS's existing infrastructure to one or more of its Internet access customer.

A method of providing digital content to a plurality of disparate users accessing Internet services at least in part via conventional two-way Internet protocol (IP) connection, said digital content comprising digital data and/or digital audio and/or digital video, the method comprising the steps of:a) formatting said digital content in accordance with an IP protocol to produce IP digital data; b) providing a streaming transmission of the IP digital data from a transmission site to a distant routing station at an internet service provider's internet point of presence through one or more substantially one-way data flow bandwidth portions of a digital communications medium that is substantially unaffected by conventional two-way IP Internet communications traffic; and c) providing, from the Internet service provider's Internet point of presence, multicast access of said IP digital data received via streaming transmission at the Internet service provider's Internet point of presence by step (b) to said plurality of disparate users accessing Internet services via two-way IP connection. 3. The method of claim 2 wherein one or more of said substantially one-way data flow bandwidth portions comprise one or more video content channels.4. The method of claim 2 wherein one or more of the substantially one-way data flow bandwidth portions comprise one or more audio content channels.5. The method of claim 2 further including the step of receiving and processing at least one IP request from at least one of said separate users.6. The method of claim 2 wherein the multicast access service provided in step c) is localized to a predetermined geographic region.7. The method of claim 2 wherein the digital communications medium substantially unaffected by conventional two-way IP Internet communications traffic comprises, at least in part, an extraterrestrial satellite communications system.8. The method of claim 2 wherein the digital communications medium substantially unaffected by conventional two-way IP Internet communications traffic is a substantially terrestrial communications system.9. The method of claim 2 wherein the digital communications medium substantially unaffected by conventional two-way IP Internet communications traffic is a reserved portion of a commercial IP communications network.10. A method of providing digital streaming content to a plurality of disparate users accessing Internet services at least in part via conventional two-way Internet protocol (IP) connections, the streaming digital content comprising digital data and/or digital audio and/or digital video, the method comprising the steps of:a) transmitting the digital streaming content from a transmission site to a distant routing station at an Internet service provider's Internet point of presence through one or more substantially one-way data flow bandwidth portions of a digital communications medium that is substantially unaffected by conventional two-way IP Internet communications traffic; and b) providing, from the Internet service provider's Internet point of presence, access to the digital streaming content received at the Internet service provider's Internet point of presence via step (a), by multicast transmission to said plurality of disparate users accessing Internet services via two-way IP connection. 11. A method of providing access to multicast digital content to a plurality of disparate users accessing Internet services at least in part via two-way Internet protocol (IP) connections, the digital content comprising digital data and/or digital audio and/or digital video information, the method comprising the steps of:a) transmitting the digital data from a transmission site to a distant routing station at an Internet service provider's Internet point of presence through one or more substantially one-way data flow bandwidth portions of a digital communications data transport service or transmission medium that effectively bypasses congested portions of the Internet and remains substantially unaffected by IP Internet communications traffic; b) receiving the digital data, transmitted by step (a), at said routing station; and c) providing access to the digital data by multicast transmission delivery from said Internet point of presence to said plurality of disparate users accessing Internet services via two-way IP connection. 12. A method of transmitting digital data, said digital data comprising streaming and/or non-streaming data encompassing both video and audio information content, to a plurality of disparate Internet users accessing Internet services at least in part via conventional two-way Internet protocol (IP) connection, the method comprising the steps of:a) transmitting the digital data to at least one distant Internet point of presence of an Internet service provider through one or more substantially one-way data flow bandwidth portions of a digital communications medium that is disparate from and substantially unaffected by conventional two-way IP Internet communications traffic; and b) multicast transmitting the digital data from said at least one distant Internet point of presence to said plurality of disparate Internet users over a two-way IP network connecting said at least one Internet point of presence to said disparate Internet users, wherein at least one or more of said plurality of disparate Internet users employ digital communications equipment that utilizes an Internet browser program or its equivalent to access Internet services. 13.
