IP MULTICAST RECEPTION TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide an IP multicast reception terminal that not only quickly carries out switching of a video image or voice but also suppresses disturbance of the video image or the voice.

SOLUTION: A reception channel selection module 303 registers a multicast group for allowing high-order application to carry out data processing by a packet data processing module 301 in a reception multicast table 103b of a multicast management table 103 apart from the multicast group participating on the basis of IGMP (Internet Group Membership Protocol). An IP packet reception module 101 carries out analysis of an IP header and IP fragment reconstruction only in the case where a destination IP address of the received IP packet is registered in the reception multicast table 103b.
