阅读:623发布:2020-12-21

专利汇可以提供Error detecting method for sub code signal专利检索,专利查询,专利分析的服务。并且PURPOSE: To exactly judge whether the error correction of a sub code is completely executed or not by extracting a pack for error detection from a sub code signal to be obtained by combination, comparing the extracted data with prescribed data and discriminating the inclusion of error in the case of dissidence.
CONSTITUTION: The sub code signals recorded to a disk 1 as EFM signals are successively recorded for the unit of the pack. Namely, in the train of the MIDI packs composed of MIDI data, packs P1, P2, P3, P4... for error detection are arranged at prescribed intervals. A processor in a MIDI controller 24 discriminates whether the packs for error detection are supplied from a pack extraction circuit 27 for error detection or not, and when the pack for error detection is supplied, it is identified whether the data field of the pack for error detection is coincident with prescribed data or not. Thus, it can be exactly judged whether the error correction of the sub code is completely executed or not.
