Portable CD player and burner {PORTABLE CD PLAYER AND BURNER}

The present invention relates to a portable CD player and burner, in particular to playing CDs, reading data, and adding to CDs (CDs such as VCDs, DVDs, regular CDs, CDs stored in software file formats for burning, blank CDs for burning, etc.). In order to meet the various needs of users, such as making a spare, computer systems used in video / acoustic consumer electronics systems and CD-ROM players (such as DVD players, CD players) of CD / RW players (CD-RW, CD player and burner incorporating a DVD-ROM).

As the storage technology of multimedia and photologic has evolved, the tendency to use various video / acoustic information on CDs is accelerating. For example, VCD used for recording MPEG1 data format, DVD used for recording MPEG2 data format, CD-DA used for recording general music format, and the like. Such CDs are used in large quantities to store media of various video / sound programs such as movies, television, operas, music concerts, record players, and the like. Apparatus corresponding to such a CD-ROM, for example, an application apparatus such as a DVD player, VCD player, CD player, CD walkman and the like can be connected to a television set, a projector, a speaker and the like.

On the other hand, the CD has a large capacity and a secure data retention capability, which is particularly suitable for the storage of extra data. Thus, the field of computer technology focuses on the speed of access and the technology of burning and copying CDs. Today, CD-ROM players have long been the basis of personal computers, primarily read-only CD-ROM players (CD-ROM, DVD-ROM, etc.) and writable CD-ROM players (CD-RW, DVD-RW, DVD + RW, etc.).

The two kinds of CD players mentioned above are both peripherals (drivers) rather than applications. The difference between a driver and an application device is that the application device operates independently, while the peripheral device (driver) can only function under the backup of the host. For example, a DVD-RW is a peripheral device in a computer that does not perform the function of decoding and outputting the image data of a CD, and does not function on the screen of the computer without relying on a backup of the CPU and video display card on the computer's main board. Can't show dynamic video. On the other hand, the DVD player independently performs a decoding function for the image data of the CD, and outputs the data through an AV jack or the like for performing the purpose of watching a movie.

In particular, the portable CD player and burner of the present invention mainly includes a housing, a CD R / W device, an operation unit, a motherboard, a multiplexer, a CPU, a memory, a signal conversion device, and at least one input / output device. The CD inserted in the CD R / W device can be switched to be path-converted by the multiplexer, and the data is encoded and decoded by the CPU, the storage device, and the signal conversion device after the operation unit commands. The signal is then transmitted via a signal converter and input / output device to a computer system or video / acoustic consumer electronics system, or a conventional CD-ROM player or CD player can simultaneously operate two different systems-a computer and a video / acoustic consumer electronics-. In order to solve the problem of not being used in the computer, data from the computer system is transmitted to the CD R / W device for input.

The main purpose of the present invention is to support the playback and burning of all multimedia video / sound CDs, CDs stored in the form of software files for burning, blank CDs for burning, and to provide input / output devices for multipurpose and convenient use. To provide a portable CD player and burner that can be combined with a projector, speaker, or personal computer.

Another object of the present invention is to use the present invention to integrate a CD-ROM player and a video / sound player, each of which is used in two different systems including a computer and a video / acoustic home appliance in the terminal of the device. This can meet the requirements of playing CD-ROM players from various customer groups, reading data, making data redundant, and so on, to significantly reduce spending on the use of CD-ROM tools.
