Abstract
An apparatus and a method for realizing a configuration for transmitting and outputting captured data of a video camera to a specific device via a network are provided. In a configuration for generating a transmission packet containing the captured data of the video camera and outputting the transmission packet via a network, a host name of a data transmission destination device and a port number, to which port forwarding processing of a relay device of a network connected to the data transmission destination device is set, are acquired from a memory, address information corresponding to the host name is acquired from a DNS server, and a captured image data containing transmission packet in which the address information and the port number are set as destination information is output via the network. This configuration permits data to be certainly transmitted to a specific selected device and reproduction of stream data in synchronization with a capturing timing is realized.
