ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is related to data transfer operations and, in particular, to a system for transferring digital data from a computer to a digital data storage (recording) device, such as a minidisk recorder/player, using a computer sound card as an interface between the computer and the digital device.
With the increase of Internet usage as a source of audio information (fee-based or otherwise), data transfer operations between a personal computer (PC) and a recording device take on a more important role than ever. For example, users access the Internet via a PC or web devices available on the market and “browse the Web” by “surfing” for audio information. It may be possible for these users to transfer (download) audio information, such as songs or other musical recordings, from their favorite music Web sites on the Internet and record the downloaded audio information on recording devices (minidisk player or Video Tape Recorder (VTR), for example) for subsequent reproduction (namely, to listen to the song, etc).
While the above operations of obtaining musical recordings, etc. from the Internet may be just as costly as going to a record store and purchasing a disk or a digital audio tape by a favorite artist, the convenience of sitting at home and having the audio information at one's fingertips is unsurpassed. Hundreds or thousands of titles available for preview and purchase/recording at home without leaving one's chair has unparallel appeal to many audiophiles as well as those who simply enjoy music for relaxation and unwinding effect after a long workday. This convenience, however, has to be user-friendly and at the level which any Web user can enjoy. Namely, novice and expert users of the Internet, as well as anyone in between, has to be able to use the transfer of audio information from the Internet easily and quickly. For widespread appeal, it is important that Internet users be able to carry out this operation without any additional devices (whether internal or external hardware), complicated setups or any other complicated apparatus or techniques that can truly be relegated to the world of “computer wizards” or alike. For example, except for the intelligent device (such as the PC for example) for accessing the Internet, a sound (audio) card installed in the PC, and two cables for supplying the output information from the PC to a minidisk player/recorder, no additional devices should be present in the system for transferring and recording audio information to the minidisk player/recorder.
A need therefore exists for a system and method for realizing the above criteria.
OBJECTS OF THE INVENTION
It is an object of the present invention to provide a system for transferring data between a computer and a digital storage (recording) device.
It is another object of the present invention to provide a system for transferring audio and accompanying digital control data between a computer and a digital storage (recording) device using an audio card in the computer.
It is a further object of the present invention to provide a system for downloading data from the Internet and transferring the downloaded data to a digital storage (recording) device using an audio card.
SUMMARY OF THE INVENTION
These and other objects, features and advantages are accomplished by a system for transferring digital data. The inventive system comprises a computer including a programmable controller for processing input digital data, and a sound card for converting the processed digital data to analog form. The system also includes a recording device connected to the computer via at least one cable. The recording device includes a processor for receiving the converted data from the sound card via the cable and for converting the received data to digital form.
In accordance with one aspect of the present invention, the digital data in the system is comprised of audio data and non-audio data including text data or control data. The programmable controller in the computer adds a code to the input digital data for identifying the audio data.
