METHOD, DEVICE AND MEDIA FOR DECODING AUDIO SIGNALS WITH SKIP-Blocks

Claims

1. A method for decoding an audio signal, wherein the method comprises the steps of receiving a bit stream containing at least one frame, wherein each frame of the at least one frame contains a plurality of blocks; determining from the signaling data information for identifying for each frame a subset of one or more blocks of the plurality of blocks to be decoded based on the device information for the output device; and decoding an identified subset of one or more blocks from the plurality of blocks.

2. The method according to claim 1, wherein the information for identifying a subset of one or more blocks from a plurality of blocks comprises a matrix that associates each output device from the plurality of output devices with a subset of one or more blocks.

3. The method of claim 2, wherein said one or more frames are required to decode the bit stream for a corresponding associated output device.

4. The method according to any one of paragraphs. 1-3, in which the output device may comprise at least one of a wireless device, a mobile device, a tablet computer, a single-channel speaker, a multi-channel speaker and / or an audio reproduction system.

5. The method according to any one of claims 1 to 4, wherein one or more blocks contain partially and / or completely at least one audio signal for reproduction based on device information in an output device.

6. The method according to any one of claims 1-5, wherein the output device is a first output device, further comprising a step of applying joint coding technologies between one or more bit stream signals to at least a second output device.

7. The method according to any one of claims 1-6, wherein the identification data of each output device and / or decoder is specified during the system initialization phase.

8. The method according to any one of paragraphs 1-7, in which the signaling data is determined from metadata of the bit stream.

9. A method for generating an encoded bit stream of an audio signal, wherein the method comprises the steps of forming a bit stream containing at least one frame, wherein each frame of the at least one frame contains a plurality of blocks; determining for each frame, based on the device information for the output device, signaling data for identifying a subset of one or more blocks of the plurality of blocks to be decoded; and encoding a bit stream with signaling data identifying a subset of one or more blocks from a plurality of blocks to be decoded, during decoding.

10. The method according to claim 9, wherein the information for identifying one or more blocks from the plurality of blocks to be decoded during decoding comprises a matrix that associates each output device from the plurality of output devices with a subset of at least one audio signal.

11. The method of claim 10, wherein said one or more frames are required to decode the bit stream for a corresponding associated output device.

12. The method according to any one of paragraphs. 9-11, in which the output device may comprise at least one of a wireless device, a mobile device, a tablet computer, a single-channel speaker, a multi-channel speaker and / or an audio reproduction system.

13. The method according to any one of paragraphs. 9-12, in which one or more blocks contain partially and / or completely at least one audio signal for reproduction based on the device information in the output device.

14. A device capable of implementing the method according to any of paragraphs 1-13.

15. A non-transitory machine-readable storage medium containing a sequence of instructions that, when executed, cause one or more devices to perform the method according to any one of paragraphs 1-13.
