Describe operating process of the present invention now in detail.

During power connection, U28 CPU makes intercommunication port, time, interruption and various interior initialization of register, and it also makes the display part of key I/O part 20, MIDI sound source unit part and external unit partially-initialized; And when choosing certain melody with switch, it deposits in by the MIDI address that will be externally comprised in the MIDI expanding element part prepares to read outside MIDI ROM in the shortest time in the specific memory of U30.

U28 regularly confirms the switch element part by U32.The melody of being chosen by U41 number is judged through U39 and to be obtained a numeral, makes this numeral shinny by U43.These running programs were regularly carried out by the set time.

When melody was chosen by U41, U28 chose the extended address of U36 and U37, and by U1 and U2 choose corresponding melody data and deciphered.When U28 sent to IC2 with 31.25 kilo hertzs speed with these addresses, IC2 read the data that IC9 takes a sample by the PCM method, and sends it to IC4.IC4 converts digital signal to simulating signal, is amplified under low frequency by IC5, and by loudspeaker it is exported.

The serial clock impulse starting U4 that U1 produces makes it produce the HSYNC signal, by U4 this HSYNC signal is imported among the U23.According to the HSYNC signal of input U23, U19 produces composite video signal.U23 will convert remote state through the composite video signal that U54 compares and two kinds of external image signals choosing, the HSYNC signal of importing U23 and U19 produce to and offer the folded part of reflecting of external image.

From the demoder of the VSYNC output signal of U23 input U10, and as the signal of the signal source of difference odd field and even field.

When finishing aforesaid operations, the signal on the panel forms linear loop, and external image itself appears on the panel simultaneously.U18 receives the address that is selected from U1, produces the RAS signal, and U5 then produces the CAS signal according to described signal.

RAS and CAS signal that U18 and U5 produce regularly offer U6 and U7, by U6 and U7 these signals are refreshed.U1 reads and stores character and the U16 of image and the data of U17, is handled in U13, U14 and U15, and it is deposited among the U6 and U7 of screen storage area.

U5 reads those by the pixel that signal write down of continuous generation corresponding to a pixel of screen, with their storage a period of times, again they is sent to U11 in U12.U11 handles them with the speed of U5 twice, thereby exports three light units (red, green and blue).

R, G, the B input end of the signal input U23 of these outputs with the outer video signal synchronization that produces among the U54, carry out electric current then and amplify.After this, the visual input end that they are input to TV converts the visual information that can be come out by the naked eyes sensing to.Like this, the shape of word just is presented on the televisor.

Information is to the favorable U28 of standard MIDI performance with monitor that exchange between the U1 of captions device has promoted the asynchronous communication with the FIFO buffer of U30, and the captions CPU (central processing unit) of U1 only shows a line character by the data that send through U28 or according to the color of playing time change character on televisor.

When the present invention wants on televisor or display monitor central monitoring system displayed image, the folded image control MPU (U1) and video synchronization signal synchronization that reflects cell mesh of external image, and continuously with form reciprocal and exponential form with character ROM (U16, U17) and RAM (U13, U14, U15) address wire converts dual number and random number to, reads these data then.Input D/A switch part (U11) converts analog video signal to data once just reading directly.Therefore, be very fast compared with the processing speed of existing pictorial data, thereby not only can amplify, dwindle, go up volume and flip image, but also can accelerate its slewing rate, improve its resolution.
