METHOD AND DEVICE FOR QUANTIZATION OF LINEAR PREDICTION COEFFICIENT AND METHOD AND DEVICE FOR INVERSE QUANTIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17947249 titled 'METHOD AND DEVICE FOR QUANTIZATION OF LINEAR PREDICTION COEFFICIENT AND METHOD AND DEVICE FOR INVERSE QUANTIZATION

Simplified Explanation

The patent application describes a quantization apparatus that includes two quantization modules: one for quantization without inter-frame prediction and another for quantization with inter-frame prediction.

  • The first quantization module consists of a first quantization part for quantizing an input signal and a third quantization part for quantizing the first quantization error signal.
  • The second quantization module consists of a second quantization part for quantizing a prediction error and a fourth quantization part for quantizing the second quantization error signal.
  • Both the first and second quantization parts utilize a trellis structured vector quantizer.

Potential applications of this technology:

  • Video compression: The quantization apparatus can be used in video compression algorithms to efficiently encode and compress video data.
  • Image compression: The apparatus can also be applied in image compression techniques to reduce the size of image files without significant loss of quality.
  • Data transmission: The quantization apparatus can be used in data transmission systems to compress and transmit data more efficiently.

Problems solved by this technology:

  • Efficient quantization: The apparatus provides a method for quantizing signals with and without inter-frame prediction, allowing for more efficient compression of video, images, and other data.
  • Improved compression quality: By utilizing a trellis structured vector quantizer, the apparatus can achieve higher compression quality compared to traditional quantization methods.

Benefits of this technology:

  • Enhanced compression efficiency: The quantization apparatus enables more efficient compression of data, resulting in reduced storage requirements and faster transmission speeds.
  • Improved video and image quality: By utilizing inter-frame prediction and a trellis structured vector quantizer, the apparatus can achieve higher compression quality, leading to better video and image reproduction.
  • Versatility: The apparatus can be applied to various applications, including video compression, image compression, and data transmission, making it a versatile solution for different industries.
