Abstract
The CODEC adjustment system is used when an incoming call is received for emergency services and the received audiovisual data does not reflect the information useful to the emergency services operator. The operator may want to hear background noise or increase the fidelity of the call in order to identify voices or determine the full extent of the emergency. Using the CODEC adjustment system, the operator or the caller can change the parameters of the sending CODEC during the emergency services call such that the encoded data contains the desired information.
