Apparatus and method for providing call quality information

An electronic device comprising:

• at least one memory;
• and
• at least one processor, coupled to the at least one memory, to perform a process comprising:
• receiving an encoded call signal and bandwidth information on the encoded call signal from a transmitting terminal;
• decoding the received encoded call signal at a first reference sampling rate;
• resampling the decoded call signal at a sampling rate supported by an outputter that is associated with the electronic device to output the resampled call signal from the electronic device;
• and
• generating call quality information based on at least one of the bandwidth information, the first reference sampling rate, and the sampling rate supported by the outputter.

A method comprising:

• by a transmitting terminal,
• resampling an input signal at a reference sampling rate, wherein
• the input signal having been received by the transmitting terminal from an inputter, included in or connected to the transmitting terminal to input the input signal to the transmitting terminal, and then, prior to the resampling, having been sampled at a sampling rate supported by the inputter, or
• the input signal having been generated by decoding content prestored in the transmitting terminal or provided from an external content provider to the transmitting terminal;
• encoding the resampled input signal;
• and
• transmitting, to a receiving terminal, the encoded input signal and bandwidth information, wherein
• when the input signal was received by the transmitting terminal from the inputter and then, prior to the resampling, was sampled at the sampling rate supported by the inputter, the bandwidth information is based on the reference sampling rate and the sampling rate supported by the inputter,
• when input signal was generated by decoding content prestored in the transmitting terminal or provided from an external content provider to the transmitting terminal, the bandwidth information is based on a sampling rate at which the content was decoded, and
• the encoded input signal and the bandwidth information transmitted to the receiving terminal are for use by the receiving terminal to generate information on a call quality related to a bandwidth used for a call between the transmitting terminal and the receiving terminal.

A method comprising:

• by a receiving terminal,
• receiving an encoded call signal and bandwidth information on the encoded call signal from a transmitting terminal;
• decoding the received encoded call signal at a first reference sampling rate;
• comparing a sampling rate supported by an outputter included in or connected to the receiving terminal to the first reference sampling rate;
• in response to the comparing indicating that the sampling rate supported by the outputter is different from the first reference sampling rate, resampling the decoded call signal at the sampling rate supported by the outputter and generating call quality information based on the first reference sampling rate and the sampling rate supported by the outputter, wherein the outputter is to output the resampled call signal from the receiving terminal;
• and
• in response to the comparing indicating that the sampling rate supported by the outputter is identical to the first reference sampling rate, generating the call quality information based on the bandwidth information and the first reference sampling rate.
