Publication number: 20200127846Abstract: The present document relates to transcoding of metadata, and in particular to a method and system for transcoding metadata with reduced computational complexity. A transcoder configured to transcode an inbound bitstream comprising an inbound content frame and an associated inbound metadata frame into an outbound bitstream comprising an outbound content frame and an associated outbound metadata frame is described. The inbound content frame is indicative of a signal encoded according to a first codec system and the outbound content frame is indicative of the signal encoded according to a second codec system. The transcoder is configured to identify an inbound block of metadata from the inbound metadata frame, the inbound block of metadata associated with an inbound descriptor indicative of one or more properties of metadata comprised within the inbound block of metadata, and to generate the outbound metadata frame from the inbound metadata frame based on the inbound descriptor.Type: ApplicationFiled: December 17, 2019Publication date: April 23, 2020Applicants: DOLBY LABORATORIES LICENSING CORPORATION, DOLBY INTERNATIONAL ABInventors: Andreas SCHNEIDER, Christof FERSCH, Martin WOLTERS, Jeffrey RIEDMILLER, Scott Gregory NORCROSS, Michael GRANT

Publication number: 20190335285Abstract: Audio content coded for a reference speaker configuration is downmixed to downmix audio content coded for a specific speaker configuration. One or more gain adjustments are performed on individual portions of the downmix audio content coded for the specific speaker configuration. Loudness measurements are then performed on the individual portions of the downmix audio content. An audio signal that comprises the audio content coded for the reference speaker configuration and downmix loudness metadata is generated. The downmix loudness metadata is created based at least in part on the loudness measurements on the individual portions of the downmix audio content.Type: ApplicationFiled: July 8, 2019Publication date: October 31, 2019Applicants: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Michael Ward, Jeffrey Riedmiller, Scott Gregory Norcross, Alexander Stahlmann

Patent number: 10015612Abstract: Some methods may involve receiving a block of audio data, the block including N pulse code modulated (PCM) audio channels, including audio samples for each of the N channels, receiving metadata associated with the block of audio data and receiving a first set of values corresponding to reference audio samples. A second set of values, corresponding to audio samples from the block of audio data, may be determined. The first and second set of values may be compared. Based on the comparison, it may be determined whether the block of audio data is synchronized with the metadata.Type: GrantFiled: May 23, 2017Date of Patent: July 3, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Kent Bennett Terry, Scott Gregory Norcross, Jeffrey Riedmiller

Publication number: 20180151188Abstract: Apparatus and methods for generating an encoded audio bitstream, including by including program loudness metadata and audio data in the bitstream, and optionally also program boundary metadata in at least one segment (e.g., frame) of the bitstream. Other aspects are apparatus and methods for decoding such a bitstream, e.g., including by performing adaptive loudness processing of the audio data of an audio program indicated by the bitstream, or authentication and/or validation of metadata and/or audio data of such an audio program. Another aspect is an audio processing unit (e.g., an encoder, decoder, or post-processor) configured (e.g., programmed) to perform any embodiment of the method or which includes a buffer memory which stores at least one frame of an audio bitstream generated in accordance with any embodiment of the method.Type: ApplicationFiled: January 23, 2018Publication date: May 31, 2018Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Michael GRANT, Scott Gregory NORCROSS, Jeffrey RIEDMILLER, Michael WARD

Publication number: 20180095718Abstract: Embodiments are directed to a method and system for receiving, in a bitstream, metadata associated with the audio data, and analyzing the metadata to determine whether a loudness parameter for a first group of audio playback devices are available in the bitstream. Responsive to determining that the parameters are present for the first group, the system uses the parameters and audio data to render audio. Responsive to determining that the loudness parameters are not present for the first group, the system analyzes one or more characteristics of the first group, and determines the parameter based on the one or more characteristics.Type: ApplicationFiled: December 7, 2017Publication date: April 5, 2018Applicants: Dolby Laboratories Licensing Corporation, DOLBY INTERNATIONAL ABInventors: Jeffrey RIEDMILLER, Scott Gregory NORCROSS, Karl Jonas ROEDEN
