Embodiment

Central processing unit is connected with TV functions module, I/O control function module, network function module, USB connector, BIOS storage chip, sound partial function module, notebook memory bar, electronic hard disc or notebook hard disk, CPU cooperation chip respectively, and this TV functions module also is connected with LCD with tuner respectively.

Central processing unit is responsible for all external informations are gathered and call allocation, realizes that by the traditional notebook internal memory the temporary and conversion of data is called.The utility model adopts standard notebook hard disk or the solid state hard disc memory device as data, greatly conserve space and save power consumption., be derived as the burning voltage of system works and the operating voltage of other each functional module work respectively, and have the effect of voltage stabilizing and filtering by processing by the power management chip of the Enable Pin Control work that powers on external dc power.The I/O part is complemented each other by pci bus mode and system by W83627 external keyboard and mouse signal is implemented monitoring.Sound partly adopts ALC203 acoustic processing module to cooperate power amplifier segment chip EUA6011AQIT1 to realize also can realizing sound input and output, microphone input function to the processing and amplifying of sound.The utility model connects USB port for the user provides in one of 2 circumscribed USB port, by the CS5526 chip it is controlled.The TV functions module of specialty has adopted main flow IC MST719 as master chip, the utility model directly matches this kind of IC on the mainboard of LX800 processor, conserve space and reduced power consumption to greatest extent, this IC provides the LVDS interface of standard can realize external LCD liquid crystal display screen, and cooperates tuner to realize the reception of TV signal.Infrared receiving port provides the function selecting of an external remote for system, and the user can come the switching of controlling computer and television interfaces by remote controller, and can restarting and off-mode with the remote controller controlling computer.System BISO has partly adopted traditional BISO flash chip, important initialization informations such as storage system log-on message.

System power supply is the direct current input mode; system cooperates the peripheral circuit of adjusting by power management chip when external power supply is imported; power supply is divided into four groups of different voltages to be used for each functional module of system; and each several part voltage is monitored; this part provides power protecting circuit for system in addition, prevents that circuit from short-circuit conditions occurring and causing mainboard to burn.Central processing unit cooperates with processor cooperation chip, realization is to the control and the feedback information of mainboard major function, internal memory is realized the memory function of temporarily calling of data and system information, data storage medium in whole system has electronic hard disc or notebook hard disk to finish, the utility model connects the USB mouth in one in 2 circumscribed USB mouths and is user-friendly to USB device for purposes provides, exist as the main equipment form at this USB, thereby can provide power supply to realize the normal use of other USB device other USB device.The Ethernet interface that system provides is supported power supply and data indicated number, shows to show amber light when green light has transfer of data when power connection.System provides the dual track mode aspect acoustic processing, supports the input of input and output mode and microphone, and the user can select external active audio amplifier or use the inner passive mode of reserving.BISO for system provides initialization information, provides convenient use of keyboard and mouse interface of P/S2 for the user by I/O control chip the utility model in system start-up.
