# kVTDecompressionPropertyKey_ReducedCoefficientDecode

Requests approximation during decoding.

```
let kVTDecompressionPropertyKey_ReducedCoefficientDecode: CFString
```

## Discussion

This is an optional property for video decoders to implement. Only decoders for which such approximations make sense should implement this property. The meaning of the number of coefficients will be decoder-specific.
