单次拷贝源数据的记录/管理设备及其方法
摘要：
本发明涉及单次拷贝(copy－once)源数据的记录/管理设备及其方法。在本发明中，单次拷贝源数据指按照MPEG－4制式编码，并存储入记录媒介内时，不允许再进行复制的复制管理信息与MPEG－4相关联被存储入设备的存储装置内，当播放所述记录媒介内存储的文件时，以所述复制管理信息为基础，控制图像输出，在模拟输出的图像信号中，插入宏观镜像，在作为数字输出的图像信号内，插入了包含不再允许复制数据的CGMS(拷贝发生管理系统)信息。因此，单次拷贝源数据被按照MPEG－4制式编码，具有能够防止被无端复制的效果。
摘要（英）：

The invention relates to recording / managing equipment for copy-once source data and the means thereof. In the invention, the copy-once source data relates to that encoded according to MPEG-4 format and stored in a recording medium, copy managing information of not allowing further copies is correlated with the MPEG-4 and stored in the storing device of the equipment, when the files stored in the recording medium is played, image output is controlled based on the copy managing information, macro mirror images are inserted into the analog-output picture signal, and CGMS (copy generating managing system) information of not allowing further copies is inserted into the picture signal which is output as digits. Therefore, copy-once source data encoded according to MPEG-4 format has the effect of preventing copies for no reason.
