Abstract: A medium having a plurality of data blocks stored therein is disclosed. The medium can be a DVD. The plurality of data blocks can be viewed by playing the medium in a medium player. The medium player can be a DVD player. A first instruction set instructs the medium player to play the plurality of data blocks of the medium in a pre-determined sequence. Further, a second instruction set instructs the medium player to play the plurality of data blocks of the medium in response to user commands that determine the order for playing the plurality of data blocks of the medium.

Abstract: A system and method for initiating communication in real-time between two users in a multi-user communication environment. To limit the receipt of unwanted messages, a unique code is provided to a first user and transmitted by the first user to a second user outside of the multi-user communication environment. The second user may then initiate real-time communication with the first user after the code is authenticated in the multi-user communication environment. To ensure secure and comprehensible communications, at least one word may be selected from a first menu having a plurality of words to enable a second menu comprising a plurality of words. A string is formed by selecting at least one of a word from the second menu which string may then be communicated to at least one of a user or a program in the multi-user communication environment.

Abstract: An apparatus has an antenna distance setting mechanism that sets a distance between a cosmetic cover and a radio antenna. An upper housing and a radio antenna, which has a ground and a radiating element and is movably attached to the upper housing, are covered by a cosmetic cover formed of a dielectric material. An antenna distance setting mechanism includes a radio antenna supporting member, elastic members, and protrusions. The radio antenna-supporting member is movably attached to the upper housing. When the cosmetic cover is attached to the upper housing, an inner wall of the cosmetic cover pushes the ends of the protrusions against an elastic force of the elastic members to set the distance between the radiating element and the inner wall of the cosmetic cover to a predetermined distance.

Abstract: Methods and apparatus for the rapid adaptation of classification systems using small amounts of adaptation data. Improvements in classification accuracy are attainable when conditions similar to those that present in adaptation are observed. The attendant methods and apparatus are suitable for a wide variety of different classification schemes, including, e.g., speaker identification and speaker verification.

Abstract: It is one object of the present invention to provide a method and system for embedding an electronic watermark directly in an MPEG stream. An intra-macroblock of an I-frame or of a P or B-frame is detected in an MPEG stream, and following the detection of an intra-macroblock of the I-frame or of the P or B-frame, data for one macroblock are extracted from the MPEG stream and buffered. An embedding pattern is embedded in the buffered macroblock without changing the length of VLC, and the resultant macroblock is returned to the MPEG stream. More specifically, a DC factor is extracted from the buffered macroblock, and a pseudorandom number is generated to produce an embedding pattern. Then, whether the bit length of the DC factor will not be changed by embedding the obtained embedded pattern is determined. When the bit length of the DC factor not be changed, the embedding pattern is embedded in the buffered macroblock.
