  • Patent number: 12170093
    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.

  • 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: 20240357214
    Abstract: There are disclosed techniques for performing personalization in a social media environment. E.g., there are disclosed techniques for multi-device and multi-user personalized and interactive audio for example through social media metadata. In one example, there is defined a streaming client device, comprising: a communication interface, to receive, from a streaming server system and/or from another streaming client device, at least one media stream and personalization option metadata enabling personalization options for rendering the at least one media stream according to the personalization options; a metadata engine, to generate personalization settings addressing the personalization options, wherein the communication interface is configured to transmit, to the streaming server system and/or to at least one second streaming client device, and/or to store, personalization metadata describing personalization settings of the at least one media stream.

  • 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.
