Patent number: 8626503Abstract: An audio encoder (109) has a hierarchical encoding structure and generates a data stream comprising one or more audio channels as well as parametric audio encoding data. The encoder (109) comprises an encoding structure processor (305) which inserts decoder tree structure data into the data stream. The decoder tree structure data comprises at least one data value indicative of a channel split characteristic for an audio channel at a hierarchical layer of the hierarchical decoder structure and may specifically specify the decoder tree structures to be applied by a decoder. A decoder (115) comprises a receiver (401) which receives the data stream and a decoder structure processor (405) for generating the hierarchical decoder structure in response to the decoder tree structure data. A decode processor (403) then generates output audio channels from the data stream using the hierarchical decoder structure.Type: GrantFiled: September 15, 2010Date of Patent: January 7, 2014Inventors: Erik Gosuinus Petrus Schuijers, Gerard Herman Hotho, Heiko Purnhagen, Wolfgang Alexander Schildbach, Holger Horich, Hans Magnus Kristofer Kjoerling, Karl Jonas Roeden

Patent number: 8447621Abstract: The present invention proposes a new method and a new apparatus for enhancement of audio source coding systems utilizing high frequency reconstruction (HFR). It utilizes a detection mechanism on the encoder side to assess what parts of the spectrum will not be correctly reproduced by the HFR method in the decoder. Information on this is efficiently coded and sent to the decoder, where it is combined with the output of the HFR unit.Type: GrantFiled: August 9, 2011Date of Patent: May 21, 2013Assignee: Dolby International ABInventors: Kristofer Kjörling, Per Ekstrand, Holger Hörich
