Bad Frame Interpolation

What Does Bad Frame Interpolation Mean?

Bad frame interpolation occurs after packets are lost and/or corrupted, especially when using Voice over Internet Protocol (VoIP). Bad frame interpolation aims to replace the bad packets by estimating potential packet values using the previously received voice frames. It enhances voice quality to make voice transmission more reliable despite errors.

Techopedia Explains Bad Frame Interpolation

Bad frame interpolation is a critical process used to avoid the voice quality issues associated with packet loss or packet corruption during calls.

Data packets may be lost for two main reasons:

  • Sometimes line quality degrades due to moisture or other environmental issues, which makes the line attenuation too high for any signal to survive the noise.
  • Sometimes packets may be lost due to a problem with the backbone of the digital network, where packets were supposed to follow a certain route. However, the route may change due to an outage in one of the route nodes.
