THE APPARATUS FOR CONVERTING LIGHT WEIGHT REALTIME TRANSPORT PROTOCOL AND THE METHOD THEREOF

摘要

A device and a method for converting a lightweight real-time media transfer protocol of a USN(Ubiquitous Sensor Network) are provided to apply to monitoring equipment and a video monitoring device installed to a spot difficult to check within a distance reached by a Zigbee wireless communication network. A receiving unit(510) receives first packet data according to a first protocol from a USN node. A protocol convertor(520) converts the first packet data into second packet data according to a second protocol of an external Internet network. A transmitting unit(530) stores and transmits the second packet data to the external Internet network. The protocol convertor includes a threshold buffer(522) and an RTP(Real-Time Transport Protocol) packet data generator(524). The threshold buffer stores the first packet data up to a predetermined threshold size. The RTP packet data generator converts the first packet data stored in the threshold buffer into the second packet data according to the second protocol.
