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.
Claims19
A method in a computer system having a memory and a processor for adjusting CODEC parameters during a call, the method comprising:
- receiving an incoming call for emergency services, the incoming call comprising encoded data, wherein the encoded data is produced by a CODEC having at least one adjustable parameter and wherein the CODEC is configured to filter background noise from the incoming call;
- decoding the encoded data;
- playing the decoded data so that it can be heard by an operator;
- receiving an indication of a determination that the CODEC is filtering too much background noise from the incoming call, the determination having been made by the operator after hearing the played decoded data;
- displaying to the operator a user interface for adjusting the background noise filter of the CODEC;
- receiving from the operator an indication to adjust the background noise filter of the CODEC;
- sending by the processor a request to change a first parameter and a second parameter of the CODEC, the second parameter for adjusting the background noise filter so that the CODEC filters less of the background noise from the incoming call;
- and
- auditing the requested change by storing an indication of the requested to change the first parameter and the second parameter of the CODEC.
A computer-readable storage medium containing instructions to change the quality of data received in a call by adjusting the parameters of a CODEC that encodes the data, by a method comprising:
- during an emergency services call,
- receiving, at a callee's site, call data produced by the CODEC and containing encoded audiovisual information,
- receiving from the callee an indication of a determination that the call data contains less than the amount of information desired by the callee as a result of overfiltering by the CODEC;
- displaying to the callee a user interface for adjusting parameters of the CODEC to adjust the amount of information filtered by the CODEC,
- receiving from the callee an adjustment of at least one parameter of the CODEC to adjust the amount of information filtered by the CODEC, and
- sending from the callee site to a caller site a request to adjust a parameter of the CODEC to adjust the amount of information filtered by the CODEC.
A system for adjusting CODEC parameters during an emergency services call, comprising:
- a call receiving component that receives a call comprising encoded data, wherein the encoded data is produced by a CODEC having adjustable parameters;
- an output component for outputting the received call to a user so that the user can determine whether the CODEC is filtering too much information from the call based on the amount of information contained in the received call relative to an amount of information desired by the user;
- a user interface component that displays a user interface with controls for adjusting a parameter of the CODEC and receives a selection from the user indicating a new value for the parameter based on the user's assessment of the amount of information within the call relative to the amount of information desired by the user;
- and
- a CODEC adjusting component that adjusts the parameters of a CODEC based on the received selection.
