Abstract:
PURPOSE: A method for matching objects between sound sources and a device thereof are provided to decode other sound sources in reproducing object based sound sources and preprocess the other sound sources when objects of the object based sound sources are matched. CONSTITUTION: A device for matching objects between object based sound sources receives a matching target sound source and an object(S210). The device adjusts the speed of other objects included in other sound sources according to a reference object of set reference sound sources(S220). The device adjusts the lengths of sound sources of the speed-controlled other objects(S230). The device matches the objects(S240).
Abstract:
PURPOSE: A multimedia content transcoding method of home network and a system thereof are provided to convert codec of multimedia content into code which a multimedia reproducing apparatus supports. CONSTITUTION: A control point performs compatibility test of codec(S201). The control point searches for a corresponding transcoder in case a reproducing apparatus does not support the codec(S203). The transcoder performs trnascoding of source content by the codec(S301). The control point determines the completion of transcoding(S209). The reproducing apparatus reproduces target content(S403).
Abstract:
PURPOSE: A method for building search criteria for home network multimedia content and a device thereof are provided to prevent the generation of invalid search criteria and easily build the valid search criteria by obtaining the feature value and keyword of multimedia from a media server in advance. CONSTITUTION: A feature value input unit(105) receives one or more feature values of multimedia content. A keyword input unit(101) receives one or more keywords extracted from the feature values. A condition input unit(111) receives search condition of the keywords. A search criteria building unit(109) builds search criteria to search the multimedia by using the keywords according to the search condition. A keyword selecting unit(103) receives a selected search keyword as a search target from the keywords.
Abstract:
PURPOSE: An up-mixing method for converting a stereo channel input signal into a multichannel output signal and an apparatus thereof are provided to apply a sound source separation technique in a stereo signal itself, thereby maintaining spatial properties including sound sources during a mixing process of a multichannel signal. CONSTITUTION: An up-mixing apparatus divides an input signal of a stereo channel into a plurality of sub-bands in a frequency range(S210). The sub-band with a highest mutual correlation is selected as a representative sub-band by measuring a mutual correlation between two channels of a stereo input signal(S220). A sound source level difference value between estimated two channels is determined as a first sound image fixing level difference value by analyzing the stereo input signal(S230). A sound image fixed sound source signal and reverberation signal are separated(S240). A sound image fixing level difference value is calculated with respect to a front channel of a multichannel speaker output system(S250). The up-mixing apparatus synthesizes the separated sound image fixed sound source signal and reverberation signal into a multichannel output signal(S260).

Abstract:
A method for serving inquiry content by a soap operation is provided to serve accurate and various results of contents inquiry by sorting and grouping the questioned contents when requesting the contents inquiry. A request message for an SOAP inquiry operation to which a request element field type is added is transmitted in order to request the various contents searches based on a complex operation. In case that the request message has a request element field type which designates a result value of inquiry request, an inquiry result expression value which corresponds to a table field designated at the request field type element is extracted. In addition, the expression value of the inquiry is added to an inquiry result element and the inquiry result element is transmitted through a response message of the SOAP operation. The response message sorts and groups the inquiry results depending on the requested contents.
Abstract:
A multimedia retrieval method for supporting asynchronous retrieval environment is provided to protect a session even though the connection session is cut off and receive retrieval results continuously by analyzing question contents, carrying out the retrieval, and storing/managing the question results after disconnecting from a server. A multimedia retrieval method comprises the steps of: asking a client server for establishing a retrieval question session(1); transmitting a message of the retrieval question, asking for the retrieval, and receiving the message(2); transmitting a receiving confirmation message to the client(3); disconnecting from a server and analyzing question contents(4); carrying out the retrieval(5); storing and managing the question results(6); asking the server for the question results(7); and returning the question results to the client or transmitting the retrieval results(8).
