Audio data processor
First Claim
Patent Images
1. An audio data processor comprising:
- a receiver for receiving packets each containing coded data obtained by encoding audio linear data; and
a coded data obtaining section for obtaining said coded data from said packets received by said receiver, wherein said coded data obtaining section includes;
a detector for detecting a missing packet from said packets received by said receiver; and
a data interpolator for interpolating coded data of said missing packet, when detected by said detector, by interpolation coded data generated on the basis of coded data of a preceding packet normally received immediately before said missing packet.

Abstract
An audio data processor includes a packet receiver for receiving audio data packets and a coded data extractor for extracting coded data from the received packets. When an error detector detects a receiving error of a packet in the packet receiver, a data interpolator generates interpolation coded data on the basis of coded data of a packet normally received immediately before the missing packet, and interpolates coded data of the missing packet by the interpolation coded data.
