FIELD: physics, video.
SUBSTANCE: invention relates to a broadcasting system for transmitting a digital television program, particularly a transmission device and a transmission method, in which content which meets needs can be acquired. A server generates a script PDI-S for obtaining a user side PDI-A representative of an answer of a user to a question about user preferences; generates launch information for executing the PDI-A; and transmits the launch information and PDI-S in response to the delivery of broadcast content, and transmits to the client in response to the delivery of reference content a provider side PDI-A representative of an answer set by a provider to the question. The client executes the PDI-S based on detection of launch information and carries out matching between the user side PDI-A and the provider side PDI-A to determine acquisition of reference content delivered by the server.
EFFECT: facilitating delivery of content to a client which satisfies the needs thereof at that time.
