A data transferring device and a data transfer method. The data transferring device for transferring an audio-visual stream stored in a first medium to a second medium, includes: a reader comprising reading circuitry configured to read the audio-visual stream from the first medium; and a controller configured to: extract an audio packet and a video packet from the audio-visual stream; write the audio packet and video packet to the second medium; and store, in a memory, first location information indicating locations at which the audio packet and the video packet are written in the second medium, and second location information indicating locations at which the audio packet and the video packet are read from the first medium.

An electronic device comprising: an internal memory which has a folder for back-up; and a first controller, wherein the first controller outputs playlists of an application to the folder for back-up of the internal memory as a playlist file when a playlist managing device is connected to the electronic device.

A portable apparatus includes a first connector, a memory, and first circuitry. The first connector automatically receives a plurality of content data from a computer. The memory stores the plurality of content data. The first circuitry performs a mutual authentication process with the computer via the first connector, and plays back the plurality of content data. The computer includes second circuitry and a second connector. The first circuitry stores the plurality of content data to a storage medium, and provides a graphical user interface to receive an input identifying a list of the plurality of content data stored in said storage medium that are to be automatically transferred to the portable apparatus. The second connector is configured to transfer the plurality of content data stored in the storage medium to the portable apparatus.

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 video replay system which allows for the playback of video files from a buffer in random access memory and from disk to minimize the delay between capturing and replaying a desired video portion. In one embodiment, a portion of RAM is allocated to provide a buffer for holding video files in memory before the files are written to a hard drive or other non-volatile storage. An index of key frames is also stored in the buffer. The computer system executes software that is responsive to an operator's commands to read the video files and index and playback desired video portions in a variety of modes and speeds, including slow motion, reverse, fast-forward, and slow or fast reverse.

An information processing device includes: a data processing unit that executes a process of reproducing content recorded in a medium; and a memory storing a content revocation list in which an identifier (ID) of revoked content is recorded, wherein the data processing unit compares a minimum allowable version of a content revocation list recorded in a token which is management data corresponding to content recorded in the medium with a version of a content revocation list acquired from the memory, and when the version of the content revocation list acquired from the memory is an old version lower than the minimum allowable version of the content revocation list recorded in the token, the data processing unit halts determination on revocation of content based on the content revocation list acquired from the memory and reproduction of content.

A system and method for creating an electronic icon containing information unique to a particular user including information allowing access with respect to a particular digital media file having the icon associated therewith over a communication network by a third party.

An article of manufacture includes a machine-readable medium that stores a multimedia content file in a first format and multiple program sets. Each program set is a version of software that, when executed by a respective electronic system, produces the multimedia content file in a second format for use in the respective electronic system. A first program set is compatible with a first operating system executed by a first electronic system and a second program set is compatible with a second operating system executed by a second electronic system. The second operating system is distinct from the first operating system.

A data transferring device and a data transfer method. The data transferring device for transferring an audio-visual stream stored in a first medium to a second medium, includes: a reader comprising reading circuitry configured to read the audio-visual stream from the first medium; and a controller configured to: extract an audio packet and a video packet from the audio-visual stream; write the audio packet and video packet to the second medium; and store, in a memory, first location information indicating locations at which the audio packet and the video packet are written in the second medium, and second location information indicating locations at which the audio packet and the video packet are read from the first medium.

An information processing apparatus includes a data processing section for reproducing contents stored in a medium having a general purpose area in which encrypted contents and corresponding utilization controlling information are stored and a protected area including a plurality of blocks having access limitation set thereto and including a block having an encryption key for decrypting the encrypted contents stored therein. The data processing section acquires utilization controlling information corresponding to a content from the general purpose area, decides, based on the utilization controlling information, whether validity period information indicative of a content utilization permission period is to be acquired from the utilization controlling information or the encryption key storage block, acquires the validity period information based on a result of the decision and then compares the acquired validity period information and current date information to decide permission or inhibition of content reproduction.
