Abstract
Data received by a receiver is processed at a sampling rate indicated manually or automatically in the receiver. The sampling rate of the received data is controlled in accordance with the processing rate. The sampling rate controlled data is then processed so as to convert its frequency distribution to that the received data originally had.
Claims6
A receiver apparatus for receiving a signal including an encoded sound signal transmitted from a transmitter, comprising:
- a decoder for decoding the encoded sound signal to thereby produce a decoded signal;
- a sample rate converter for controlling a count of samples of the decoded signal per unit of time, based on first information about control of sample count;
- a frequency distribution converter for converting frequency distribution, based on second information about conversion of frequency distribution;
- a sample counter for measuring the count of samples;
- and
- a control information generator for generating the first information and the second information, based on the count of samples measured by said sample counter.
A method for receiving a signal including an encoded sound signal transmitted from a transmitter, comprising:
- decoding the encoded sound signal to thereby produce a decoded signal;
- converting a count of samples of the decoded signal per unit of time, according to first information about conversion of sample count;
- converting frequency distribution according to second information about conversion of frequency distribution;
- measuring the count of samples;
- and
- generating the first information and the second information, based on the count of samples.
A computer readable medium containing program instructions for receiving a signal including an encoded sound signal transmitted from a transmitter, said program instructions, when executed by one or more processors of a computer, controlling the computer to function as a receiver by executing, the steps of:
- decoding the encoded sound signal to thereby produce a decoded signal;
- converting a count of samples of the decoded signal per unit of time, according to first information about conversion of sample count;
- converting frequency distribution according to second information about conversion of frequency distribution;
- measuring the count of samples;
- and
- generating the first information and the second information.
