Abstract:
A portable CD player and burner comprising:a housing with an entrance in favor of independent operation and for placing therein a CD; a CD reading/writing unit mounted in said housing at a location in corresponding to that of said entrance; an operating unit including a display panel and a push button provided on said housing; a main board placed in said housing for providing thereon electronic elements and the elements in electrical connecting with all units of said CD player and burner; a multiplexer used to switch among the bridging paths for distribution of data signals passively, in order that the data read by said CD reading/writing unit and the command transmitted from said operating unit are transmitted to the remaining of said units of said CD player and burner for processing through said multiplexer; a CPU used to actively distribute and transmit data signals to all said units after receiving said command from said operating unit; a memory unit for providing program software and to support said CPU to process encoded and decoded codes of the formats of digital signals; a signal converting unit including a TV encoder, a digital/analog converter and a computer signal controller; said digital signals read by said CD reading/writing unit are processed by said main board, said multiplexer, said CPU and said memory unit and are transmitted to said signal converting unit to be converted into output signals; and at least an output/input unit connected between said signal converting unit and a computer system and/or a video/acoustic household electric appliance system, said output/input unit includes communication ports connectable to a computer system, and an output jack connectable to a video/acoustic household electric appliance system; a CD placed in said CD reading/writing unit is given a command from said operating unit to render said multiplexer to switch for changing path, thereby to encode and decode data through said CPU, said memory unit and said signal converting unit, then signals are transmitted to a computer system or a video/acoustic household electric appliance system via said signal converting unit and said output/input unit, or the data of said computer system are transmitted to said CD reading/writing unit for inputting, thereby functions of playing a CD, reading data and making a data spare are obtained.
