    摘要: A method and an input-output device are proposed for rendering content. Further, a servicing device is proposed for delivering pre-rendered content.For rendering, a portion of processing or memorizing resources of said input-output device is allocated such that remaining resources of said input-output device are sufficient for maintaining the input-output capability of the device. Then, it is determined that an amount of resources required for rendering exceeds the allocated resources and a corresponding degree of pre-rendering is determined, too. On the serving device, pre-rendering of the content according to the determined degree is performed and the pre-rendered content is delivered from the serving device to the input-output device.Since server-side rendering is limited to a required degree, bandwidth constraints can be met more easily. Furthermore, rendering occurs more distributed and can be adjusted dynamically, thus, response time can be reduced.

    摘要: A method for encoding a digitized audio signal which includes the step of selecting one of two or more psycho acoustic model provided for generating masking thresholds used in a data reduction process. The selecting criterion is the available data rate for the encoded bit stream. Each one of the two or more psycho acoustic models is adapted to a specific data rate of the encoded bit stream. In a second embodiment, the method includes the step of combining two or more masking thresholds resulting from different psycho acoustic models, thereby leading to a more accurate calculation of a masking threshold for the data reduction process. Further, there are appropriate apparatuses for the encoding of digitized audio signals.

    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 description. 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 performed, which enables the movement of a graphical object in the screen plane to be mapped to a movement of an audio object in the depth perpendicular to said screen plane.

    摘要: A method for calling up information about current radio and television programs wherein desired signals are transmitted together or separately with decodable additional information signals. The method includes the steps of selecting from the additional information signals that information which is directly or indirectly linked to time information. The selected information is compared with a time period which can be predetermined and within which the current time and/or the time assigned to the current program occurs. The information corresponding to this time period is then displayed on a display device of a receiving device which receives the desired signals and additional information signals. The information is displayed in response to depressing a call up key of an associated receiving device or remote controller one or more times, such that at least two fields selected from the group consisting of start time, stop time, title, and remaining run time are displayed on a portion of the display device, while another portion of the display device displays information associated with the desired signals of a current channel which the receiving device is tuned to.

    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 diffuseness 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: In an MPEG multi-channel audio signal processor, a decoder requires a respective decoder matrix for determining different output channels from coded audio data. Some transmitted information indicates basic parameters of the multi-channel system. This information may be used to address a currently required decoder matrix which is stored in a decoder memory. The storage of a large number of such matrices would be required to enable the decoder to decode all possible channel configurations. Instead of addressing a required decoder matrix stored in decoder memory, initially the current encoder matrix is reconstructed in the decoder using the related transmitted information. The required decoder matrix is then computed from the reconstructed encoder matrix using a matrix inversion technique.

    摘要: In a method of transmitting a signal wherein the signal is partitioned into windows comprised of overlapping blocks with each block containing a partial signal. The partial signal in each block is converted into a digital signal and individually coded with a selected window function f(n). The overlapping areas of the window functions are weighted such that the resultant of the overlapping functions in each block equals one. The coded signals are transmitted. The received signals are reconverted into partial analog signals. The window functions are selected in accordance with frequency changes in the original signal.

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 ID value describing the depth of said audio object.
