>Dear All,

>As you may have already known, the AACS group has modified its Bus 
>Encryption specification in response to inputs from the DVD Forum that 
>the Media Seed could be erased by legacy drive and could be set to other 
>value by new drive and therefore could not be persistent. The modified 
>Bus Encryption specification no longer uses the Media Seed and instead 
>uses two Data Keys (Write Data Key and Read Data Key). The modofication 
>of AACS Bus Encryption specification requires related changes in the Mt. 
>Fuji7 specification draft.
>
>The attached zip file contains proposed modification of Mt. Fuji7 
>specification draft. This is an official proposal from the AACS group. 
>I would like to review it and have a voting for adopting the proposal at 
>the next Mt. Fuji meeting in Colorado Springs.
>
>I will also upload the proposal to the Mt. Fuji FTP site.
