摘要： The present invention presents techniques for transmitting application specific instruction between a host and a memory card. The commands for the application specific protocol are embedded along with a signature in the data portion of a transmission protocol that is used to communicate between the host the memory card. This allows for the transmission of application specific commands that lack a corresponding command in the transmission protocol to still be transmitted in that protocol. The method can be implemented on the host side either at the device driver level or the file level. In order to implement a read command in the application specific protocol, a write command in the first protocol with an embedded read command is first sent to a logical address, followed by a second read command to the same logical address.
摘要翻译：本发明提出了用于在主机和存储卡之间传输应用程序特定指令的技术。用于应用程序特定协议的命令与用于在主机与存储卡之间进行通信的传输协议的数据部分中的签名一起嵌入。这允许在传输协议中缺少相应命令的特定于应用的命令的传输仍然在该协议中传输。该方法可以在主机端在设备驱动程序级别或文件级别上实现。为了在应用专用协议中实现读取命令，具有嵌入式读取命令的第一协议中的写入命令首先被发送到逻辑地址，然后是第二读取命令到同一逻辑地址。

摘要： Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.

摘要： One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file contains a valid RO or not. Preferably, there is a one-to-one correspondence between the location for a RO in a RO file and a location in the RO navigation file for the status bit which identifies whether its corresponding location in the RO file contains a valid RO or not. Whether a particular location in a RO file contains a valid RO or not can be found by checking its corresponding status bit in the RO navigation file. By finding out whether a particular location in a RO file contains a valid RO or not in this manner, it is possible to delete ROs without having to go through an authentication process. The process of finding an empty slot in the RO file for storing a new RO is also simplified. This greatly increases the efficiency of RO management. A similar system may be used for management of content encryption/ encryption keys for protecting content files.
摘要翻译：可以使用一个或多个权限对象（RO）文件来存储RO，优选地在仅对经认证的用户可用的保护区域中。 RO导航文件优选地存储在包含状态位的未受保护的公共区域中，其中每个状态位识别RO文件中的位置是否包含有效的RO。优选地，在RO文件中的RO的位置与用于状态位的RO导航文件中的位置之间存在一一对应关系，该状态位标识其在RO文件中的相应位置是否包含有效的RO。通过检查RO导航文件中相应的状态位，可以找到RO文件中的特定位置是否包含有效的RO。通过查找RO文件中的特定位置是否包含有效的RO，以这种方式，可以删除RO而无需经过身份验证过程。在RO文件中找到用于存储新的RO的空槽的过程也被简化。这大大提高了RO管理的效率。类似的系统可以用于管理用于保护内容文件的内容加密/加密密钥。
