STEREO PARAMETERS FOR STEREO DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18513188 titled 'STEREO PARAMETERS FOR STEREO DECODING

Simplified Explanation

The apparatus described in the patent application is a system that includes a receiver and a decoder. The receiver is responsible for receiving a bitstream containing two frames, with each frame containing specific audio information. The decoder then processes this information to generate a complete channel output.

  • Receiver receives bitstream with first and second frames
  • First frame includes mid channel portion and stereo parameter
  • Second frame includes another mid channel portion and stereo parameter
  • Decoder generates channel based on first frame information
  • In absence of second frame, decoder estimates stereo parameter based on previous frames
  • Decoder generates second portion of channel based on estimated stereo parameter

Potential Applications

This technology could be applied in audio decoding systems, such as in streaming services, broadcasting, and virtual reality applications.

Problems Solved

This technology solves the problem of incomplete frame data in audio decoding, allowing for the generation of a complete channel output even when certain frame information is missing.

Benefits

The benefits of this technology include improved audio quality, seamless playback of audio content, and efficient decoding processes.

Potential Commercial Applications

Potential commercial applications of this technology include audio streaming services, broadcast systems, virtual reality platforms, and any other audio processing systems.

Possible Prior Art

One possible prior art for this technology could be the use of interpolation techniques in audio decoding to estimate missing frame data.

Unanswered Questions

How does this technology compare to existing audio decoding methods?

This article does not provide a direct comparison between this technology and other existing audio decoding methods. It would be interesting to know the specific advantages and disadvantages of this system compared to traditional methods.

What are the limitations of estimating stereo parameters based on previous frames?

The article does not delve into the potential limitations or challenges of estimating stereo parameters based on previous frames. Understanding these limitations could provide insight into the reliability and accuracy of this technology.


Original Abstract Submitted

An apparatus includes a receiver and a decoder. The receiver is configured to receive a bitstream that includes a first frame and a second frame. The first frame includes a first portion of a mid channel and a first quantized stereo parameter. The second frame includes a second portion of the mid channel and a second quantized stereo parameter. The decoder is configured to generate a first portion of a channel based on the first portion of the mid channel and the first quantized stereo parameter. The decoder is configured to, in response to the second frame being unavailable for decoding operations, estimate the second quantized stereo parameter based on stereo parameters of one or more preceding frames and generate a second portion of the channel based on the estimated second quantized stereo parameter. The second portion of the channel corresponds to a decoded version of the second frame.
