Claim:
1. A method for implementing multicast on shared network, comprising: receiving a multicast program request from a terminal device; wherein the multicast program request comprises multicast program information and a terminal device identifier indicating the terminal device; updating a table of correspondence between multicast program and terminal device according to the multicast program information and the terminal device identifier; wherein the table of correspondence between multicast program and terminal device comprises a plurality of entries, each entry records a correspondence between multicast program information indicating a multicast program and terminal device identifier indicating terminal devices that have requested the multicast program indicated by the multicast program information of this entry; and broadcasting the updated table of correspondence between multicast program and terminal device and a multicast program according to the multicast program request to the terminal devices; wherein the updated table of correspondence between multicast program and terminal device is used to indicate whether a terminal device needs to receive the broadcasted multicast program, wherein the terminal device identifier in the entry is terminal ID mask information, wherein the terminal ID mask information comprises a plurality of bits that respectively corresponds to different terminal devices on the shared network, and each bit is used to indicate whether a corresponding terminal device requests playing of the multicast program.
