STEREO PARAMETERS FOR STEREO DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240161757 titled 'STEREO PARAMETERS FOR STEREO DECODING
Simplified Explanation
The apparatus described in the patent application includes a receiver and a decoder, with the receiver receiving a bitstream containing two frames - the first frame with a portion of a mid channel and a quantized stereo parameter, and the second frame with another portion of the mid channel and a second quantized stereo parameter. The decoder then generates a channel based on the information in the frames, and if the second frame is unavailable, estimates the second quantized stereo parameter based on previous stereo parameters and generates the corresponding portion of the channel.
- Receiver receives bitstream with two frames - first frame with mid channel portion and quantized stereo parameter, second frame with another mid channel portion and second quantized stereo parameter
- Decoder generates channel based on frame information
- If second frame is unavailable, estimates second quantized stereo parameter based on previous frames and generates corresponding channel portion
Potential Applications
This technology could be applied in audio decoding systems, multimedia devices, and communication equipment where efficient decoding of stereo parameters is required.
Problems Solved
This technology solves the problem of efficiently decoding stereo parameters in a bitstream when one of the frames is missing or unavailable for decoding operations.
Benefits
The benefits of this technology include improved efficiency in decoding stereo parameters, enhanced audio quality, and better utilization of available frame information for generating the channel.
Potential Commercial Applications
One potential commercial application of this technology could be in audio streaming services, where high-quality audio decoding is essential for providing a superior user experience.
Possible Prior Art
One possible prior art for this technology could be existing audio decoding algorithms that handle stereo parameters in a bitstream. However, the specific method of estimating stereo parameters based on previous frames may be a novel aspect of this innovation.

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.
