AUDIO DECODER, APPARATUS FOR GENERATING ENCODED AUDIO OUTPUT DATA AND METHODS PERMITTING INITIALIZING A DECODER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240212697 titled 'AUDIO DECODER, APPARATUS FOR GENERATING ENCODED AUDIO OUTPUT DATA AND METHODS PERMITTING INITIALIZING A DECODER

The abstract describes an audio decoder that decodes a bit stream of encoded audio data, which includes a sequence of audio sample values in frames. The decoder can determine if a frame is a special frame containing additional information, such as encoded audio sample values of preceding frames, to initialize the decoder for decoding the special frame.

• The audio decoder decodes a bit stream of encoded audio data.
• Each frame in the bit stream includes encoded audio sample values.
• The decoder can identify special frames with additional information.
• Additional information includes encoded audio sample values of preceding frames.
• Preceding frames are encoded using the same codec configuration as the special frame.
• Sufficient number of preceding frames to initialize the decoder for decoding the special frame.

Potential Applications: - Audio decoding systems - Multimedia devices - Communication systems

Problems Solved: - Efficient decoding of audio data - Seamless transition between frames - Initialization of decoder for special frames

Benefits: - Improved audio decoding accuracy - Enhanced performance in decoding special frames - Better overall audio quality

Commercial Applications: Title: Advanced Audio Decoding Technology for Multimedia Devices This technology can be used in various commercial applications such as: - Smartphones - Tablets - Smart speakers - Audio streaming services

Frequently Updated Research: Researchers are constantly working on improving audio decoding algorithms to enhance the efficiency and accuracy of audio decoding systems.

Questions about Audio Decoding Technology: 1. How does the audio decoder determine if a frame is a special frame? The audio decoder uses a determiner to identify special frames based on the additional information included in the frame. 2. What are the potential implications of using the same codec configuration for encoding preceding frames and special frames? Using the same codec configuration ensures compatibility and seamless decoding of audio data.

Original Abstract Submitted

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.
