What is bad frame interpolation?
Poor frame interpolation occurs after packets are lost and / or damaged, especially when using VoIP (Voice over Internet Protocol). Bad frame interpolation aims to replace the bad packets by estimating possible packet values using the previously received speech frames. It improves the voice quality to make voice transmission more reliable despite errors.
Poor frame interpolation is a critical process used to avoid the voice quality problems associated with packet loss or packet corruption during a call.
Data packets can be lost for two main reasons:
Sometimes line quality degrades due to moisture or other environmental issues, making line attenuation too high for any signal to survive the noise.
Sometimes packets can be lost due to a problem with the digital network backbone, where packets travel a certain route consequences should. However, the route can change due to a failure in one of the route nodes.
