With the increasing number of MBone sessions the interest of home users to participate in multicast sessions is also increasing. Unfortunately the cost for the hardware necessary to participate in multicast sessions over a high speed link are still prohibitively high. This paper discusses technical problems and solutions for users who wish to participate in multicast sessions over dial-in lines and presents our approach, the Dial-In Multicast Gateway, which meets the requirements for an application layer multicast router with a restrictive broadcasting policy and a dynamic tunneling mechanism. The Dial-In Multicast Gateway allows the transmission of selected multicast sessions over dial-in connections such as modems, ISDN or even new network access technologies like ADSL by providing a mechanism to configure a multicast tunnel dynamically. For each selected media stream the desired quality of service parameters can be set interactively, e.g. a certain share of the available bandwidth can be reserved. In order to allow a graceful scaling of video we integrated a simple scaling mechanism for H.261 video streams that controls the temporal resolution of the video.
