    • The invention consists of attaching or embedding a "TIRIS" transponder (or other RF or IR or barcode or other identifying device) physically into the center of the proposed DVD disk. Within the memory of the transponder, both a predetermined address and a code word are preprogrammed into the transponder at the manufacturing level of the media product. The media player not only comprises functionality to play the disk, but also comprises the functionality to transmit an interrogation signal to the transponder, and then to receive the transponder response signal. Therefore, once a disk is input to a media player, the interrogation portion of the media player transmits an interrogation signal to the transponder located on the disk. Thus once empowered with the interrogation signal, the transponder accesses the predetermined address and the code word from it's memory. Then the transponder transmits both the address and the code word to the interrogator, located within the media player, and the player accesses the particular address location on the disk. The media player only plays if there is a match between the read data-word and received code word. The comparison can occur within the interrogation portion of the media player or within the media player itself.
    • 本发明包括将“TIRIS”应答器(或其他RF或IR或条形码或其他识别设备)物理地附接或嵌入到所提出的DVD盘的中心。 在应答器的存储器内,在媒体产品的制造级别将预定地址和码字都预编程到应答器中。 媒体播放器不仅包括播放盘的功能,还包括将询问信号发送到应答器的功能,然后接收应答器响应信号。 因此,一旦将盘输入到媒体播放器,媒体播放器的询问部分向位于盘上的应答器发送询问信号。 因此,一旦授权了询问信号,应答器从其存储器访问预定的地址和代码字。 然后,应答器将地址和码字都发送到位于媒体播放器内的询问器,并且播放器访问盘上的特定地址位置。 如果读取的数据字和接收的代码字之间存在匹配,则媒体播放器才播放。 比较可以发生在媒体播放器的询问部分内或媒体播放器本身内。
