First Claim
1. A method of transmitting digital content to a plurality of separate 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 generate IP digital data;
b) providing a streaming transmission of the IP digital data from a transmission site to a remote Internet point of presence of an Internet service provider (ISP) 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;
c) multicastiag multicasting the IP digital data transmitted by step (b) from the remote Internet point of presence to a plurality of separate receiving Internet user apparatus connected to but distant from the remote Internet point of presence; and
d) contemporaneously with step c), transmitting relatively time-insensitive additional IP digital data via a conventional two-way IP connection that is separate from the one-way data flow bandwidth portions to the remote Internet point of presence and then to the plurality of separate receiving Internet user apparatus;
wherein, on each among the plurality of separate receiving Internet user apparatus, received IP digital data multicast by step (c) and received additional IP digital data transmitted by step (d) is processed to allow simultaneous use of both.

Abstract
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.
