DEVICE FOR PRESENTATION upmix signal On the basis of the downmix signal, a device for providing BITOTOVOGO stream representing the multichannel audio signal, method, computer program and bitstream employs signaling WITH CONTROL OF DISTORTION

摘要

1. A device (100; 200; 300; 400) for providing the presentation of the up-mix signal (120; 428a-428M) based on the representation of the down-mix signal (110, 414) and object-related parametric information (112; 416), which are turned on in the presentation of the bitstream of the audio content, and depending on the visualization information (114; 424); the device includes: a distortion limiter (140; 240; 340; 422) configured to adjust the upmix parameters by using a distortion control circuit (142) to avoid or limit the audible distortion caused by the inappropriate selection of visualization parameters (114; 424), where a distortion limiter is formed to obtain a distortion limiting control parameter (116; 418; q), which is included in the representation of the bitstream of the audio content, and to adjust the distortion control circuit to depending on the distortion limit control parameter; where the distortion limiter is generated to evaluate the dynamic sign (flag) of the update in terms of the presentation configuration of the bitstream of the audio content, where the distortion limiter is formed to evaluate the presentation portion of the bitstream of the audio content to obtain the distortion limit control parameter, if the dynamic sign (flag) of the update is inactive, and in order to evaluate part of the presentation frame of the sound stream bitstream neigh to obtain multiple control parameter updates distortion constraint, if the dynamic attribute (flag) of the update aktiven.2. The device (100; 200; 300; 400) according to claim 1, where the device for
