摘要： 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.

摘要： An audio processing unit, comprising a buffer memory (201) configured to store at least one frame of an encoded audio bitstream which includes audio data and a metadata container having a header and one or more metadata payloads after the header, a parser (205) coupled to the buffer memory, and an audio decoder (202) coupled to the parser. The one or more metadata payloads include dynamic range compression (DRC) metadata including DRC control values indicative of a compression profile assumed by an encoder to generate said DRC control values. The audio decoder is configured to perform dynamic range compression on decoded audio data generated by decoding said at least some of the audio data, using the DRC metadata.

摘要： Apparatus and methods for generating or decoding an encoded audio bitstream according to AC-3 or E-AC-3 format, said bitstream carrying program information metadata, PIM, within a skipfield, the addbsi or the auxdata field in addition to audio data in the bitstream. The PIM includes active channel metadata indicative of each non-silent and each silent channel of an audio program.

摘要翻译： 用于生成编码音频比特流的装置和方法，包括通过在比特流中包括节目响度元数据和音频数据，以及可选地还包括比特流的至少一个片段（例如，帧）中的节目边界元数据。 其他方面是用于对这样的比特流进行解码的装置和方法，例如，通过对由比特流指示的音频节目的音频数据进行自适应响度处理，或对这种音频的元数据和/或音频数据的认证和/或验证 程序。 另一方面是配置（例如，编程）以执行该方法的任何实施例的音频处理单元（例如，编码器，解码器或后处理器），或者包括缓冲存储器，其存储产生的音频比特流的至少一个帧 根据该方法的任何实施例。
