摘要： Content identification and quality monitoring are provided. The method involves obtaining a first fingerprint derived from a first media content, processing the first media content to generate a second media content, obtaining a second fingerprint derived from the second media content, and comparing the first fingerprint and the second fingerprint to determine one or more of: a similarity between the first fingerprint and the second fingerprint that indicates that the second media content is generated from the first media content or a difference between the first fingerprint and the second fingerprint to identify a quality degradation between the first media content and the second media content.

摘要： Techniques for adaptive processing of media data based on separate data specifying a state of the media data are provided. A device in a media processing chain may determine whether a type of media processing has already been performed on an input version of media data. If so, the device may adapt its processing of the media data to disable performing the type of media processing. If not, the device performs the type of media processing. The device may create a state of the media data specifying the type of media processing. The device may communicate the state of the media data and an output version of the media data to a recipient device in the media processing chain, for the purpose of supporting the recipient device's adaptive processing of the media data.

摘要： A media signal is accessed, which has been generated with one or more first processing operations. The media signal includes one or more sets of artifacts, which respectively result from the one or more processing operations. One or more features are extracted from the accessed media signal. The extracted features each respectively correspond to the one or more artifact sets. Based on the extracted features, a conditional probability score and/or a heuristically based score is computed, which relates to the one or more first processing operations.
摘要翻译：访问已经通过一个或多个第一处理操作生成的媒体信号。媒体信号包括分别由一个或多个处理操作产生的一组或多组伪影。从所访问的媒体信号中提取一个或多个特征。所提取的特征分别对应于一个或多个伪像集。基于提取的特征，计算与一个或多个第一处理操作有关的条件概率得分和/或启发式分数。

摘要翻译：提供了基于指定媒体数据的状态的单独数据对媒体数据进行自适应处理的技术。媒体处理链中的设备可以确定是否已经在媒体数据的输入版本上执行了媒体处理的类型。如果是这样，则设备可以调整其对媒体数据的处理以禁止执行媒体处理的类型。如果没有，则设备执行媒体处理的类型。设备可以创建指定媒体处理类型的媒体数据的状态。为了支持接收方设备对媒体数据的自适应处理，设备可以将媒体数据的状态和媒体数据的输出版本传送到媒体处理链中的接收者设备。

摘要： The present document relates to processing of multimedia data, notably the encoding, the transmission, the decoding and the rendering of multimedia data, e.g. audio files or bitstreams. In particular, the present document relates to the implementation of loudness control in multimedia players. A method for providing loudness related data to a media player is described. The method comprises the steps of providing a first loudness related value associated with an audio signal; wherein the first loudness related value has been determined according to a first procedure; of converting the first loudness related value into a second loudness related value using a reversible relation; wherein the second loudness related value is associated with a second procedure for determining loudness related values; of storing the second loudness related value in metadata associated with the audio signal; and of providing the metadata to the media player.
