Encoding circuit, encoding method, digital signal transmitting apparatus, and digital signal recording/reproducing apparatus |
摘要 |
An encoding circuit for use with a digital signal transmitting apparatus and a digital signal recording/reproducing apparatus encodes a 16-bit information word into a 18-bit code word by trellis encoding method in the condition that the range of the variation of the ADS is limited in such a manner that the 18-bit code word is composed of a combination of 9-bit sub-code words. Thus, while the channel line density and the circuit scale are being suppressed from increasing, the transmission rate of user data can be improved.
