Abstract
Provided is a pop-noise removing method. The pop-noise removing method analyzes an acoustic noise, occurring when receiving digital broadcasting under a weak electric field environment, and reduces a pop-noise on the basis of the analyzed result, for transferring digital broadcasting with a minimized pop-noise to consumers. Accordingly, an output of the pop-noise of digital broadcasting can be minimized
Claims6
A pop-noise removing method, comprising:
- performing, when a audio signal is received, a CRC on audio stream data in units of a frame;
- and
- doing, when audio frame data is determined to be broken as the CRC result, a fade-in of an audio volume at an output time of audio frame data just previous to the broken audio frame data, for preventing a pop-noise from occurring when decoding the broken audio frame data.
Dependencies are inferred from the claim text.
