Abstract
The present invention relates to a method for asynchronous multimedia content retrieval, which can be applied to TV-Anytime standard or MPEG standard. In summary, an asynchronous multimedia retrieval method is provided as including: a client establishing the first session as requesting to the server; transmitting to the server the retrieval inquiry message for contents that the server needs; terminating the first session after the retrieval inquiry; establishing the second session and requesting to the server the result for the retrieval inquiry at a certain point in time that the previously set time has passed; and receiving the retrieval result from the server and terminating the second session.
