Patent number: 7328162Abstract: The present invention proposes a new method and apparatus for the enhancement of source coding systems. The invention employs bandwidth reduction (101) prior to or in the encoder (103), followed by spectral-band replication (105) at the decoder (107). This is accomplished by the use of new transposition methods, in combination with spectral envelope adjustments. Reduced bitrate at a given perceptual quality or an improved perceptual quality at a given bitrate is offered. The invention is preferably integrated in a hardware or software codec, but can also be implemented as a separate processor in combination with a codec. The invention offers substantial improvements practically independent of codec type and technological progress.Type: GrantFiled: October 9, 2003Date of Patent: February 5, 2008Assignee: Coding Technologies ABInventors: Lars Gustaf Liljeryd, Per Rune Albin Ekstrand, Lars Fredrik Henn, Hans Magnus Kristofer Kjörling
