<p><P>PROBLEM TO BE SOLVED: To provide a digital BTSC encoder which operates successfully and is neither excessively complicated nor expensive. <P>SOLUTION: A BTSC encoder (200) includes: a left digital high pass filter (212) for receiving a digital left channel audio signal (L) and generating a digital left filtered signal; a right digital high pass filter (214) for receiving a digital right channel audio signal (R) and generating a digital right filtered signal; a matrix including an adder (216) for summing the digital left and right filtered signals and generating a digital sum signal (L+R), and including a subtractor (218) for subtracting one of the digital left and right filtered signals from the other of the digital left and right filtered signals and generating a digital difference signal (L-R); a difference channel processor (230) for digitally processing the digital difference signal (L-R); and a sum channel processor (220) for digitally processing the digital sum signal (L+R). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
