    • Provided is a method for performing hierarchical B picture-based coding on a video sequence using the structure of adaptively divided group of pictures (GOP). The method includes the steps of, for each predefined 2N frame-sized group of pictures (GOP) of the video sequence, (a) encoding the 2N frame-sized GOP of the video sequence based on each of the different GOP sizes from the maximum size, 2N, to the minimum size, 2M (M is an integer between 1 and N) and obtaining different values between frames reconstructed after the encoding is performed and frames after the hierarchical B-picture prediction is performed, based on each of the different GOP sizes; (b) selecting at least one sub-GOP based on the difference values obtained by encoding the 2N frame-sized GOP of the video sequence based on each of the different GOP sizes; and (c) generating a bitstream by encoding the 2N-frame-sized GOP based on the at least one selected sub-GOP. Thereby, the hierarchical B picture-based video coding is performed by adaptively dividing the GOP size based on performance and thereby obtains high coding efficiency.

    • A user authentication method of authenticating a user on an on-line basis using a user's e-mail address and hardware information is provided. The user authentication method includes the steps of: transmitting a user's authentication client platform hardware information and e-mail address to an authentication server module through an authentication client module installed in the authentication client platform; and the authentication client module determining user authentication according to whether or not the e-mail address and hardware information received from the authentication server module is identical to user's e-mail address and hardware information stored in an authentication database. A user's authentication request and authentication is confirmed through an e-mail in the case that authentication fails in the primary authentication process. The user authentication method performs authentication by using a user's hardware information and e-mail address, their uniqueness of which is verified. Accordingly, since a user's password is not required, inconveniences of reissuing the user's password due to losing the same can be reduced.
