First Claim
Patent Images
1. A multicast content accessing method for use on a user device, wherein a multicast service provides the multicast content, comprising:
- receiving multicast service activation data over a network;
generating on the user device a broadcast key;
sending from the user device the generated broadcast key over a network;
wherein the generated broadcast key indicates that multicast content is to be provided to the user device.

26. A multicast content accessing apparatus for use on a user device, wherein a multicast service provides the multicast content, comprising:
-
a data storage mechanism that stores user identification key and multicast service activation data;
key generation operation instructions configured to generate on the user device a broadcast key based upon the stored user identification key and the multicast service activation data;
wherein the generated broadcast key indicates that multicast content is to be provided to the user device.
