Error correction encoding method, error correction decoding method, error correction encoding apparatus, and error correction decoding apparatus
First Claim
1. An error-correction coding method for performing coding in which an error correction code to be used for correcting a transmission error at a receiving end is added to a digital audio signal to be transmitted, when transmitting a digital video signal and the digital audio signal between a transmitting end and the receiving end through a digital interface means, said method including:
- an error correction code addition step of adding an error correction code to each of samples of the igital audio signal; and
an interleaving step of interleaving continuous n (n;
integer equal to or larger than
2) pieces of samples of the digital audio signal to which error correction codes are added in the error correction code addition step, thereby to generate a coded audio signal.

Abstract
An error-correction coding method and an error-correction decoding method, in which error detection and error correction for an audio signal can be carried out when a video signal and the audio signal are multiplexed and transmitted by a DVI, is provided.
After an error correction code is added to each of samples of the digital audio signal, continuous n (n: integer equal to or larger than 2) pieces of samples of the digital audio signal, to which error correction codes are added, are interleaved to generate a coded audio signal.

13. An error-correction coding apparatus for performing coding in which an error correction code to be used for correcting a transmission error at a receiving end is added to a digital audio signal to be transmitted, when transmitting a digital video signal and the digital audio signal between a transmitting end and the receiving end through a digital interface means, said apparatus including:
-
an error correction code addition means for adding an error correction code to each of samples of the digital audio signal; and
an interleaving means for interleaving continuous n (n;
integer equal to or larger than
2) pieces of samples of the digital audio signal to which error correction codes are added by the error correction code addition means, thereby to generate a coded audio signal.
