Methods and apparatus for persistent control and protection of content

A novel method and apparatus for protection of streamed media content is disclosed. In one aspect, the apparatus includes control means for governance of content streams or content objects, decryption means for decrypting content streams or content objects under control of the control means, and feedback means for tracking actual use of content streams or content objects. The control means may operate in accordance with rules received as part of the streamed content, or through a side-band channel. The rules may specify allowed uses of the content, including whether or not the content can be copied or transferred, and whether and under what circumstances received content may be “checked-out” of one device and used in a second device. The rules may also include or specify budgets, and a requirement that audit information be collected and / or transmitted to an external server. In a different aspect, the apparatus may include a media player designed to call plugins to assist in rendering content. A “trust plugin” is disclosed, along with a method of using the trust plugin so that a media player designed for use with unprotected content may render protected content without the necessity of requiring any changes to the media player. In one aspect, the streamed content may be in a number of different formats, including MPEG-4, MP3, and the RMFF format.

Hardware assisted formatted data transfer system having a source storage controller and a formatting storage controller receiving on-media structure definition and a data definition

A system and method for hardware assisted formatted data transfer allows a formatting storage controller to read and record data on a formatted storage medium and avoids a requirement of continuous interaction by a host system in the transfer process. The host system can initiate the transfer process by sending a command block, a data definition, and an on-media structure definition to a formatting storage controller, which performs the formatted transfer and notifies the host system when the transfer is completed or an exception occurs. Alternately, the formatting storage controller can access one or more on-media structure definitions stored in a persistent storage unit in accordance with an on-media structure selector provided by the host system in the command block. In alternative implementations, the system and method of the present invention allows for the performance of a "verify copy" operation which causes the formatting storage controller to compare the formatted data recorded on the formatted storage medium with the data stored on an alternate storage medium (e.g. a source or destination storage medium) and a "formatted read" operation, which causes the formatting storage controller to read the formatted data stored on the formatted storage medium and transfer it to a destination storage medium. Further disclosed is a program product for recording data on a formatted storage medium in accordance with an on-media structure definition initiates a transfer process in accordance with a command block provided to a formatting storage controller.

Multitrack recording using multiple digital electronic devices

The present invention is a method and apparatus for multitrack recording of audio information using handheld digital electronic devices such as suitably equipped portable digital music players. Recording of video tracks by digital electronic devices to complement the audio is also contemplated. One device serves as a master; the remainder are slaves. A key aspect of the invention is the transmission of start and stop recording signals by the master, which facilitates synchronization of the various tracks. In certain embodiments of the invention, some slaves may begin preliminary sampling of audio information prior to the start recording signal. This prepares these slaves to begin the actual track recording without delay. Upon receiving the command to start recording, each slave chooses as the first frame of its, say, audio track that sample closest to the time the signal to record was received. The task of stopping recording is typically handled similarly. A recording device may store an indicator whereby the time offset of its first frame from the start recording signal can be determined, thus facilitating time interpolation of the samples in its track. In this way, all audio tracks, for example, might be transformed to a common set of time points. In a typical configuration, the master might also record a sound track or a video track.
