    • Aspects of the present disclosure relate to methods of managing and delivering digital media content data. In certain embodiments, a management device in communication to a computing device via a universal serial bus (USB) connector is provided. The management device has a processor, a volatile memory and a non-volatile memory. The non-volatile memory includes a first partition storing a firmware and a second partition. When executed at the processor, the firmware emulates an emulated bootable storage device for the computing device at the USB connector. In response to an access instruction from the computing device to access data stored at an emulated address of the emulated bootable storage device, the management device converts the emulated address to a physical address of the second partition, and accesses the data at the physical address. The data includes digital media content data and a control module configured to play the content data.
    • 本公开的方面涉及管理和传送数字媒体内容数据的方法。 在某些实施例中,提供了经由通用串行总线(USB)连接器与计算装置通信的管理装置。 管理设备具有处理器,易失性存储器和非易失性存储器。 非易失性存储器包括存储固件和第二分区的第一分区。 在处理器上执行时,该固件会模拟USB连接器上计算设备的模拟可启动存储设备。 响应于来自计算设备的访问指令来访问存储在仿真可引导存储设备的仿真地址的数据,管理设备将仿真地址转换为第二分区的物理地址,并且访问物理地址处的数据。 数据包括数字媒体内容数据和被配置为播放内容数据的控制模块。
