CONSTITUTION: An apparatus for detecting a synchronizing signal of public wave using an audio watermark comprises an ADPCM(Adaptive Differential Pulse Code Modulation) converter(3) for converting a public wave signal having the watermark into an ADPCM type; an analog/digital and digital/analog converter(2) for converting the public wave signal output from the ADPCM converter; a watermark detecting portion for detecting the watermark inserted into the public wave signal; and a synchronous signal generating portion for receiving a detected watermark signal to generate the synchronous signal of a broadcasting system. In the apparatus, the public wave signal is a voice signal. A method of detecting the synchronizing signal of public wave using the audio watermark comprises the steps of: receiving the public wave signal having the watermark through an antenna(4); converting the input public wave signal by the ADPCM method; converting the public wave signal from the ADPCM converter into an analog or digital signal; detecting the watermark; and generating the synchronous signal of the broadcasting system suing the watermark signal.

    • PURPOSE: A device and a method for encoding a 3D mesh model by analyzing connection information are provided to apply differential pulse code modulation and arithmetic encoding or determining bit encoding through analysis of a shared vertex without performing phase incision, thereby improving compression complexity of 3D model data and improving a compression rate. CONSTITUTION: A data analyzer(100) separates a vertex, an attribute and vertex connection information configuring a 3D mesh model from data of a 3D mesh model. A mesh model quantization unit(102) uses the information to generate a quantized vertex, attribute and connection information. A differential pulse code modulation unit(106) analyzes a sharing vertex of consecutive connection information of the 3D mesh model according to the quantized connection information to perform differential pulse code modulation. An entropy encoder(108) arithmetically encodes the quantized vertex, attribute information and connection information which is different-pulse-code modulated to output binary arithmetic or determining bit encoded data.
