摘要： A digital satellite broadcasting system for providing copy protection or so-called macrovision signals which hinder the recording of designated picture signals and which do not adversely affect the performance of a television receiver. Such satellite broadcasting system may include a broadcasting station (100), a satellite (200), and a plurality of satellite receivers (31) each located at a subscriber's premises and coupled to the subscriber's television receiver (60) and recording/reproducing device (VTR) (70). Parameters pertaining to a number of types of television receivers (60) may be transmitted from the satellite broadcasting station (100) by way of the satellite (200) to the satellite receivers (31). Upon receiving such transmitted parameters, each respective satellite receiver (31) obtains the parameters associated with the respective television (60). Such obtained parameters are utilized in forming a macrovision signal which is combined with video data and supplied to the respective television receiver (60). As a result of using parameters associated with the respective television receiver (60) in forming the macrovision signal, the performance of such television receiver (60) is not adversely affected and picture signals of designated programs which are recorded on the VTR (70) will produce unacceptable pictures upon reproduction so as to provide the desired copy protection.
