The present invention relates to methods and systems for extracting digital content using an interactive television application. The interactive television application may allow the user to record programs on a set-top box. The interactive television application may also allow the user to extract the audio from one of the recorded programs and transfer the extracted audio to removable media (e.g., a CD-R). The interactive television application also be configured to perform a future transfer of digital content to removable media. The future transfer may occur without requiring any further user interaction.

In the case of a conventional data structure of a disk on which data is recorded by a CD-R multisession method, a dedicated command is needed to read the latest file structure recorded during the last session by reading chainedly the first address of the subsequent session recorded in the read-in area of a session, and it is necessary to close the session so as to read data by means of a reproduction-only device. According to the invention, a set of information on management of unrecorded areas and a set of information on management of file structure/file information are recorded as chain-type information (111, 115, . . . ) and are read chainedly in a volume space so as to acquire the latest management information. Open maintenance information (105, 125) is recorded at the start of recording and close maintenance information (107, 126) is recorded at the end of the recording. The information is read chainedly, and thus information on volume is acquired.

A method for preventing the illegal copying of a copy protected content by a computerized system by installing a driver in the operating system of the computerized system for intercepting any attempt of the I/O routines of the operating system to access the device drivers of the Operating System, producing a CRC codes for data read from devices containing original copies, producing a CRC codes for data to be written to devices, and preventing any attempt to write such data whenever the CRC code produced match a CRC code produced for read data. The protection of content stored on a recordable CD can be achieved by recording on the CD a first sA method for preventing the illegal copying of a copy protected content by a computerized system by installing a driver in the operating system of the computerized system for intercepting any attempt of the I/O routines of the operating system to access the device drivers of the Operating System, producing a CRC codes for data read from devices containing original copies, producing a CRC codes for data to be written to devices, and preventing any attempt to write such data whenever the CRC code produced match a CRC code produced for read data. The protection of content stored on a recordable CD can be achieved by recording on the CD a first session including one or more Tracks, each of which includes unique and/or nonstandard data structures. The protected content is then recorded on the CD in a concealed form together with an authentication module capable of determining the existence or non-existence of the unique and/or nonstandard data structures and capable of accessing the concealed content and reveal its content. Whenever attempting to access the CD, the authentication module is activated, and if the unique and/or nonstandard data structures are found on the CD, the concealed content is revealed and accessed.

Digitally encoded content (e.g., music) is provided in a protected mode, along with a player that can unlock and/or decode this music on a user's personal computer (PC) for enjoyment only at their PC. Since the music is in a proprietary, protected form, the user cannot download to players for other formats, e.g., MP3 players, nor can a CD be burned for use external to the PC. If the user decides that they like the content and wants to use it on another playback device, e.g., a MP3 player, or copy it onto a CD-R for use in a standard audio player, the user can initiate a transaction for payment through the player. Once the transaction is completed, the player either converts or transforms the content into a format usable by the, e.g., MP3 player, or converts or transforms the content into wave format and writes it to a CD-R.

A CD-R drive has two USB ports. One USB port is connected as an ordinary interface port to a host computer by a USB cable, and the other USB port is connected as an assist power supply port to the host computer by another USB cable. With this arrangement, the CD-R drive can operate with maximum current consumption of 1.0 A without using a separate AC power supply adapter because each USB port allows passage of 500 mA of current at maximum.

A DVD playback apparatus accurately discriminates a hybrid disc, to prevent a recordable CD installed therein from being damaged by a laser beam for a DVD/MMCD. The hybrid disc includes a label printed surface formed on a substrate, a CD recording surface formed below the label printed surface, having identification information expressing a disc type, and a DVD recording surface formed below the CD recording surface. The DVD playback apparatus irradiates a CD laser beam on an optical disk installed therein. If data is readable from the optical disc, it is checked whether the identification information is recorded in the predetermined recording area. The DVD playback apparatus recognizes the optical disc as the hybrid disc, if the identification information is recorded in the predetermined recording area.

Optical medium identification codes, such as the ATIP start codes used for CD-R optical media, are preassigned by optical medium manufacturer for association with planned optical media of the manufacturer. Optical disc drive manufacturers build optical disc drives having the preassigned optical medium identification codes in write strategy tables even though the optical disc drives are manufactured and sold before release and development of write strategies for the planned optical media. General write strategies associated with the preassigned optical medium identification codes provide more rapid write speeds for optical media having preassigned codes than for optical media having unknown identification codes by basing the preassigned write strategies on planned optical media design parameters, such as similarities with existing optical media of the manufacturer.
