A method, a computer readable storage medium, and an apparatus for determining a target sound scene at a target position from two or more source sound scenes. A positioning unit positions spatial domain representations of the two or more source sound scenes in a virtual scene. These representations are represented by virtual loudspeaker positions. A projecting unit then obtains projected virtual loudspeaker positions of a spatial domain representation of the target sound scene by projecting the virtual loudspeaker positions of the two or more source sound scenes on a circle or a sphere around the target position.

A synchronisation of the presentation or reproduction of video data with audio data is described, which data each are processed on two non-synchronised computers. An MPEG-type stream is separated into video data and audio data, wherein the video data is processed utilising the first processing means and the audio data is timestamped and forwarded to the second processing means which compares the received time-stamp to the local time. The transmission time periods of sending audio data packets from the first processing means to the second processing means are calculated based on the local system time and timestamp is inserted into the audio data packets. Subsequently, synchronised audio and video presentation or reproduction is performed.

The invention relates to the technical field of data transmission via a transmission link according to the TDM method, corresponding to time division multiplex. Such a method is used in an audio mixing console in order to transport the sample words of a plurality of audio channels jointly to an audio DSP processor and, after processing, to transmit them back from said processor to an output processor. Since the data output process is performed in an automated manner with the aid of a DMA unit, severe interfering noise can occur in cases of error, said noise also being output via the loudspeakers. The invention is based on the aim of avoiding such interfering effects. An error detection method based on the marking of data frames is used for this. For this purpose, a number of marking bits of the time slot of the data frame are set, the bit pattern of the marking bits being alternated in a defined sequence. Upon error detection, the outputting of the data via the loudspeakers is prevented, such that no interfering noise arises.
