Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing residual quantization are described. One example of the methods includes performing a first residual quantization on a first target residual signal at a first bit rate to generate a first quantized residual signal. A second target residual signal is generated based at least on the first quantized residual signal and the first target residual signal. A second residual quantization is performed on the second target residual signal at a second bit rate to generate a second quantized residual signal, where the first bit rate is different from the second bit rate.

A method, comprising:
- performing a first residual quantization on a first target residual signal at a first bit rate to generate a first quantized residual signal;
- generating a second target residual signal based the first quantized residual signal and the first target residual signal;
- and
- performing a second residual quantization on the second target residual signal at a second bit rate to generate a second quantized residual signal,
- wherein the first bit rate is different from the second bit rate.
An electronic device, comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more hardware processors in communication with the memory storage, wherein the one or more hardware processors execute the instructions to:
- perform a first residual quantization on a first target residual signal at a first bit rate to generate a first quantized residual signal;
- generate a second target residual signal based at least on the first quantized residual signal and the first target residual signal;
- and
- perform a second residual quantization on the second target residual signal at a second bit rate to generate a second quantized residual signal,
- wherein the first bit rate is different from the second bit rate.
A non-transitory computer-readable medium storing computer instructions for performing residual quantization, that when executed by one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
- performing a first residual quantization on a first target residual signal at a first bit rate to generate a first quantized residual signal;
- generating a second target residual signal based at least on the first quantized residual signal and the first target residual signal;
- and
- performing a second residual quantization on the second target residual signal at a second bit rate to generate a second quantized residual signal, wherein the first bit rate is different from the second bit rate.
