    摘要： An application on a computing device to write data to a storage medium associated therewith. The data is to be written to a secure storage area associated with an object on the storage medium, and the secure storage area has a value storage area associated therewith. The application generates a nonce and employs a shared session key (KS) to encrypt the nonce to result in (KS(nonce)). The storage medium receives same and decrypts with (KS) to result in the nonce, locates the value storage area associated with the secure storage area, and stores such nonce in the located value storage area. The application employs the nonce to generate a key (KH), encrypts the data with (KH) to result in (KH(data)), and sends same to the storage medium for storage in the secure storage area. Thus, (KH(data)) is associated with the nonce in the value storage area.

    摘要： Multimedia presentations are multicast using an announcement channel that includes presentation description information along with multiple channels for multiple streams of multimedia data to accommodate clients of different multimedia resources. Clients can use the announcement channel to select channel(s) appropriate for their multimedia resources. The channels are created in a predetermined manner (e.g., preselected logical addresses, preselected ports of an IP address, etc.) so that clients can immediately join a channel without (or concurrently with) joining the announcement channel to reduce startup latency. An acceleration channel may be created that provides blocks of data containing a preselected number of previous units, which may be transmitted at at a bit rate that is “faster than real-time”. This feature allows clients with suitable resources to more quickly buffer sufficient data to begin presenting the multimedia data to users.

    摘要： In a protected media path for delivering content from a source to a sink, a source authority (SOTA) on behalf of the source decides with regard to a policy corresponding to the content that a particular type of action with the content is to be refused, and provides a particular enabler to an application. The provided enabler includes information and methods necessary for the application to obtain data necessary to respond to the refusal. The application receives the enabler at an interface thereof and the interface applies a common interaction procedure to run the enabler to obtain the data necessary to respond to the refusal.
