Patent CA-2406576-C (CA)
Inventor: MALAH DAVID
IPC: G10L21/02
Filed: 2002-10-04
Granted: 2007-12-18
Abstract: A system and method are disclosed for extending the bandwidth of a narrowband signal such as a speech signal. The method applies a parametric approach to bandwidth extension but does not require training. The parametric representation relates to a discrete acoustic tube model (DATM). The method comprises computing narrowband linear predictive coefficients (LPCs) from a received narrowband speech signal, computing narrowband partial correlation coefficients (parcors) using recursion, computing M nb area coefficients from the partial correlation coefficient, and extracting M wb area coefficients using interpolation. Wideband parcors are computed from the M wb area coefficients and wideband LPCs are computed from the wideband parcors. The method further comprises synthesizing a wideband signal using the wideband LPCs and a wideband excitation signal, highpass filtering the synthesized wideband signal to produce a highband signal, and combining the highband signal with the original narrowband signal to generate a wideband signal. In a preferred variation of the invention, the M nb area coefficients are converted to log-area coefficients for the purpose of extracting, through shifted-interpolation, M nb log-area coefficients. The M wb log-area coefficients are then converted to M wb area coefficients before generating the wideband parcors.

Abstract: The present invention relates to a method of copy protecting optical discs, such as CD-ROMs. Instead of encoding data onto the CD-ROMs in a manner which ensures balanced dc content, for copy protection the digital data is encoded and recorded onto the optical disc such that it is arranged to give some of the recorded digital data unbalanced dc content. Thus, for example, the DSV  value of the encoded data may be changed rapidly in less than (100) frames to (Figure 9). For an area of digital data on the optical disc in which the DSV  has been caused to rise steeply (Figure 10a), heavy distortions in audio arise (Figure 10c) during an attempt to copy an audio track including the single segment of unbalanced dc content.
