First Claim
Patent Images
1. A method comprising:
- decoding compressed data using a dequantizer to recover high priority data from a received signal, the high priority data being associated with spectral envelope data of input data that was previously encoded as the received signal before the received signal was received; and
recovering. from the received signal, low priority data associated with residual spectrum data of the input data using a side model, the side model being concurrently trained with the training of a quantizer used to encode the input signal, the quantizer trained with respect to the high priority data.

Abstract
An apparatus for providing improved data compression may include an encoder comprising a quantizer for encoding input data and a side model. The quantizer may be trained with respect to high priority data among the input data and may be configured to partially encode the input data by encoding the high priority data. The side model may be trained jointly with the training of the quantizer and is configured to model low priority data among the input data.
