Power line broadcasting transmission / reception apparatus and transmission / reception method of visual broadcasting information using complex frequency code

摘要

PURPOSE: A power line transmission and reception apparatus of video broadcast information by using a complex frequency code and a transmission and reception method thereof are provided to exclude a mutual influence of a harmonic signal that is generated by a nonlinearity of an alternating frequency. CONSTITUTION: A power line(100) transmits a predetermined power signal. A broadcast signal formation apparatus(200) encodes one or more video broadcast information among a year, a month, a day, an hour, a minute and a second that are corresponding to the specific zero crossing view point of a current power signal. The broadcast signal formation unit creates a video broadcast signal that is composed by different frequency of a complex frequency code according to a coded video broadcast signal. A broadcast signal associated apparatus(300) combines the video broadcast signal with a power signal.
