Abstract
The disclosure provides a match-rule based service message transfer method and system in the IPTV, to address the problems in the IPTV message system of message storing and backlog, low push efficiency and poor usability. In the disclosure, match fields are arranged in a set-top box and a service message to be sent, the service message is sent by means of broadcast or multicast, the set-top box performs matching for the match fields based on the match rule, and filters the message. The disclosure avoids sending a service message by means of unicast, increases the push efficiency and can greatly reduce the storage load of offline messages in a message system. The formed message may be sent according to a single or combined policy which depends on a specific service attribute, thereby greatly facilitating the service operation.
