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: A basic frequency extraction apparatus, vocal melody extraction apparatus, and method thereof are provided to enable a user to easily search a sound source by effectively extracting a vocal melody. CONSTITUTION: A frequency peak detection unit(120) detects a frequency peak in the frequency spectrum of a music signal. A basic frequency candidate determination unit(130) analyzes values corresponding to the location of a peak value. The basic frequency candidate determination unit selects the basic frequency candidate included in the input signal. A basic frequency determination unit(140) selects one or more basic frequency candidates among plural basic frequency candidates.

PURPOSE: An electronic program guide offering apparatus and method thereof are provided to display the preference of a user on an electronic program guide. CONSTITUTION: A first receiver(110) receives broadcasting program information. A preference data calculator(120) calculates preference data of a broadcasting program from broadcasting program information. An EPG(Electronic Program Guide) data generator(130) generates EPG data. A memory unit(140) stores a watching usage history.
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:
PURPOSE: A humming or song-based sound source searching method and system are provided to improve sound source search performance using the audio signal(humming data) of a user inputted to an audio input unit. CONSTITUTION: An error pattern map(102) stores a pitch providing a sound height extracted from user humming and a humming error pattern, information about chroma which is a scale extracted from the user humming. An input unit(100) is input the audio signal of a user. A pre-processor(104) performs the pre-processing of the audio signal which is inputted with the use of the humming error pattern saved in the error pattern map. A search engine unit(108) refers to the sound source of the pre-processed audio signal.

Abstract:
PURPOSE: A method for constituting an album using an audio file stored in a recording medium is provided to increase convenience of a user by constituting an album with various audio files stored in all types of recording medium. CONSTITUTION: A category used for classifying an audio file is set(S10). The category of the audio file is automatically classified by analyzing all audio file stored in the recording medina according to category information(S18). An album stored the audio file according to the category and constituted the file(S20). The automatic classification is preformed by using name information of the audio file, index information embedded in the audio file, and analyzing data of tempo of the audio file and bit characteristics.
