摘要： A method for decoding a data stream containing audio/video substreams (14) and control substreams comprises buffering nodes (12) having the possibility to buffer multiple data packets in the same buffer. This may be achieved by having separate parameters for the allocated buffer size and any stored packet. Thus, not only multiple packets may be stored in the buffering node (12), but also such node may exist while its buffer is empty, so that the node may be reused later. This is particularly useful for buffering and selectively accessing multiple audio packets in MPEG-4 audio nodes or sound nodes.
摘要翻译：一种用于对包含音频/视频子流（14）和控制子流的数据流进行解码的方法包括具有在同一缓冲器中缓冲多个数据分组的可能性的缓冲节点（12）。这可以通过为分配的缓冲区大小和任何存储的分组具有单独的参数来实现。因此，不仅可以在缓冲节点（12）中存储多个分组，而且在其缓冲器为空时也可以存在这样的节点，以便稍后可以重用该节点。这对于缓冲和选择性地访问MPEG-4音频节点或声音节点中的多个音频分组特别有用。

摘要： In the MPEG-4 standard ISO/IEC 14496:2001 several audio objects that can be coded with different MPEG-4 format coding types can together form a composed audio system representing a single soundtrack from the several audio substreams. In a receiver the multiple audio objects are decoded separately, but not directly played back to a listener. Instead, transmitted instructions for mixdown are used to prepare a single soundtrack. Mixdown conflicts can occur in case the audio signals to be combined have different channel numbers or configurations. According to the invention an additional audio channel configuration node is used that tags the correct channel configuration information items to the decoded audio data streams to be presented. The invention enables the content provider to set the channel configuration in such a way that the presenter at receiver side can produce a correct channel presentation under all circumstances. An escape code value in the channel configuration data facilitates correct handling of not yet defined channel combinations.
摘要翻译：在MPEG-4标准ISO / IEC 14496：2001中，可以用不同MPEG-4格式编码类型编码的几个音频对象可以一起形成代表来自多个音频子流的单个音轨的组合音频系统。在接收机中，多个音频对象被单独解码，但不直接回放到收听者。相反，用于混音的传输指令用于准备单个音轨。要组合的音频信号具有不同的通道号或配置时，可能会发生混频冲突。根据本发明，使用附加的音频通道配置节点，其将正确的信道配置信息项标记到要呈现的解码音频数据流。本发明使得内容提供商能够以这样一种方式设置频道配置，使得接收机侧的演示者可以在任何情况下产生正确的频道呈现。通道配置数据中的转义码值有助于正确处理尚未定义的通道组合。

摘要： A method for implementing an IIR filter (100) on a parallel processing hardware platform (200) such as a GPU (340), comprises separating the IIR filter into a sequence of biquad filters (110), implementing each biquad filter as a separate thread (120) with one or more processing elements (130) each, assigning to the first thread a first output memory block (140), and to the last thread a first input memory block (150), assigning to each of the remaining threads an input memory block (150) and an output memory block (140), executing each of the threads with a first block of data (160) to be processed, and when all threads (120) are finished, assigning to the first thread a different second output memory block and to the last thread a different second input memory block, assigning to each of the remaining threads a different input memory block and a different output memory block than before, such that each output memory block of a thread becomes a new input memory block of the next thread, and each input memory block of a thread becomes a new output memory block of the previous thread, and executing each of the threads with a second block of data (160) to be processed. The above steps are repeated for all blocks of the data to be processed.

摘要： Method for describing the composition of audio signals, which are encoded as separate audio objects. The arrangement and the processing of the audio objects in a sound scene is described by nodes arranged hierarchically in a scene de-scription. A node specified only for spatialization on a 2D screen using a 2D vector describes a 3D position of an audio object using said 2D vector and a 1D value describing the depth of said audio object.In a further embodiment a mapping of the coordinates is per-formed, which enables the movement of a graphical object in the screen plane to be mapped to a movement of an audio ob-ject in the depth perpendicular to said screen plane.

摘要： A parametric description describing the wideness of a non-point sound source is generated and linked with the audio signal of said sound source. A presentation of said non-point sound source by multiple decorrelated point sound sources at different positions is defined. Different dif-fuseness algorithms are applied for ensuring a decorrelation of the respective outputs. According to a further embodiment primitive shapes of several distributed uncorellated sound sources are defined e.g. a box, a sphere and a cylinder. The width of a sound source can also be defined by an opening-angle relative to the listener. Furthermore, the primitive shapes can be combined to do more complex shapes.

摘要： The transmission and use of real, i. e. of measured, room impulse responses for the reproduction of sound signals with this room characteristic compatible to the MPEG-4 standard is made possible by inserting impulse responses in multiple successive control parameter fields (15, 16, 17, 18), espe-cially the params[128] array. A first control parameter field (15) contains information about the number and content of the following fields. For presentation of the sound sig-nals the content of the successive control parameter fields is separated, stored in an additional memory of a node (12) and used during the calculation of the room characteristic.

摘要： So that listeners can compile their radio service on an individual basis, broadcasts are classified according to the respective information content, and the broadcasts in each information class are sent in a respective data stream at parallel times. At the reception end, the data streams are simultaneously picked up, are possibly buffer-stored, and are forwarded to a reproduction device according to individual stipulations.
