A system and method for securely delivering and updating media using portable storage. In one embodiment, field-modifiable storage presents itself to the host system as a read-only standardized media player, where the user adds, replaces, or updates media onto that storage. A further embodiment establishes encrypted streaming from field-modifiable storage directly into the graphics processor of the viewing host, bypassing the general-purpose computing infrastructure.

Aspects of the disclosure relate to systems and methods of recording video frames from a computing device by a management device. The management device may receive video frames from the computing device. In response to receiving the video frames, the management device may process the video frames in a first-in-first out (FIFO) order to generate processed video frames according to a recording method, store the processed video frames in the FIFO order in the memory of the management device, and then release the memory occupied by some of the processed video frames in the FIFO order based on a memory releasing condition defined by the recording method to store the processed video frame. The memory releasing condition is determined by multiple optimized parameters of the recording method. The recording method may be a sliding window recording method, a multiple-window fixed size recording method, or a multiple-window dynamic size recording method.

An information processing device including: a data processing unit that generates an encryption key of content; and a communication unit that transmits an encryption key generated by the data processing unit, wherein the data processing unit generates, as the encryption key, individual keys that are different for each new content recording processing on a recording medium in a content recording device, and transmits the individual keys through the communication unit.

Improved techniques to utilize and manage a group of media items (or media assets) on a computing device are disclosed. The group of media items can be utilized and managed at a host computer for the host computer as well as a media device (e.g., media player) that can couple to the host computer. One popular example of a group of media items is know as a playlist, which can pertain to a group of audio tracks. One aspect pertains to providing a persistent media device playlist at a host computer. Another aspect pertains to imposing capacity limits to a playlist, such as a media device playlist. Still another aspect pertains to a graphical user interface that enables a user to trade-off storage capacity of a media device between media asset storage and data storage. Yet still another aspect pertains to a graphical user interface that assists a user with selecting media items to fill a group of media items.

An improved portable media device and methods for operating a media device are disclosed. According to one aspect, the portable media device can also function as a solid-state drive for data storage. The form factor of the portable media device can be hand-held or smaller, such that it is highly portable. The portable media device can use one or more status indicators. The portable media device can also include a peripheral bus connector, a rechargeable battery, and one or more input devices. According to another aspect, the portable media device has the capability to store media device status information in persistent memory before powering down. Thereafter, when the portable media device is again powered up, the stored media player status information can be retrieved and utilized. According to still another aspect, the portable media device can form and/or traverse a media asset playlist in an efficient manner.

A system, a removable memory device and a method for fruition of multimedia contents are provided, wherein the user can instantly mark a multimedia content as favourite by pressing a button while that content is in reproduction. The archive containing the favourite multimedia contents, along with non-favourite contents, is updated immediately, so that said archive, which is stored in a removable memory device, can be moved from one reproduction apparatus to another. One variant of the invention allows also older-generation reproduction apparatuses, which cannot handle playlists and metadata, to reproduce favourite multimedia contents while excluding those that have not been marked as such.
