  • Publication number: 20250061906
    Abstract: An audio decoder decodes a bit stream of encoded audio data, which bit stream represents a sequence of audio sample values and includes a plurality of frames, wherein each frame includes associated encoded audio sample values. The audio decoder includes a determiner configured to determine whether a frame of the encoded audio data is a special frame including encoded audio sample values associated with the special frame and additional information, wherein the additional information include encoded audio sample values of a number of frames preceding the special frame, wherein the encoded audio sample values of the preceding frames are encoded using the same codec configuration as the special frame, wherein the number of preceding frames is sufficient to initialize the decoder to be in a position to decode the audio sample values associated with the special frame if the special frame is the first frame upon start-up of the decoder.

  • Publication number: 20240404540
    Abstract: An audio decoder for providing a decoded audio signal representation on the basis of an encoded audio signal representation is configured to adjust decoding parameters in dependence on a configuration information, to decode one or more audio frames using a current configuration information, to compare a configuration information in a configuration structure associated with one or more frames to be decoded by the current configuration information, and to make a transition to perform decoding using the configuration information in the configuration structure associated with the one or more frames to be decoded as a new configuration information if the configuration information in the configuration structure associated with the one or more frames to be decoded, or a relevant portion thereof, is different from the current configuration information, and to consider a stream identifier information included in the configuration structure when comparing the configuration information.

  • Patent number: 12149762
    Abstract: Audio video synchronization and alignment or alignment of audio to some other external clock are rendered more effective or easier by treating fragment grid and frame grid as independent values, but, nevertheless, for each fragment the frame grid is aligned to the respective fragment's beginning. A compression effectiveness lost may be kept low when appropriately selecting the fragment size. On the other hand, the alignment of the frame grid with respect to the fragments' beginnings allows for an easy and fragment-synchronized way of handling the fragments in connection with, for example, parallel audio video streaming, bitrate adaptive streaming or the like.

  • Publication number: 20240355340
    Abstract: A streaming client device receives a bitstream, which includes an encoded audio signal according to an encoded audio signal version selected among multiple selectable versions, each having at least one personalization option among multiple personalization options. The bitstream also includes side information with configuration information and capacity information. The streaming client device: defines a personalization, by choosing a preferred selectable version based on the capacity information and the configuration information; selects an encoded audio signal version based on a current state of the external resource and the personalization, so that the capacity required by the selected encoded audio signal version matches the current state of the external resource; and decodes the received encoded audio signal or transcodes it onto another bitstream.
