3、制作辅助文件 hdcpkey_index.bin，该文件保存当前 KEY 的索引值，每烧录一次该值会
递增 1。初始值设置为 0 即可。该文件制作方法同 mac.bin 的制作方法，初始化只需要在第一
个字节写入 00 即可，如下图所示：
3) upgrade HDCP_KRY by factory menu
A . prepare relevant document about HDCP_KEY
1. use slice tools to incise a file from master key ,which include the keys should
be used to product the same day
2. renamed the key file to hdcpkey.bin
3. make a auxiliary file hdcpkey_index.bin, this file save the index number of
present key, it will add 1 every time when a key was burned. It is initial was
0.the way to make this file is same as mac.bin, and initialize it just need to
write the first bit to 00
，
as follow image

4、HDCPKEY 文件制作完毕，保存文件并拷贝至 U 盘，准备烧录。再次制作其它机型的辅助
文件 hdcpkey_index.bin 时，只需要将此文件拷贝后将第一个字节修改为 00 即可。
4.after HDCPKEY is completed
，
save the file and copy to USB flash disk for going to
burned
。
Next time
，
when making the auxiliary file hdcpkey_index.bin for other TV
，
just
need to copy it and write the first bit to 00.
说明：hdcpkey_index.bin 文件有记忆，为了防止 U 盘丢失，导致无法知悉 KEY 的上次截
